SKSE Plugin Texture Generation Performance Issues

Share

WL

I have compiled a SKSE plugin with latent funcionality. It compiles and appers to function correctly when it comes to generating images. However when generating DDS images with the BD7 format it causes the computer to go to 100% utilization and the game freezez untill the image capture returns. Is DirectxTK thread save or Is there a problem with the thread yielding control? Can this behavior be fixed

It sounds like you're encountering a thread blocking issue with your SKSE plugin when generating DDS images with the BC7 format (assuming you meant BC7 rather than BD7).

DirectXTK is not fully thread-safe for all operations. While some utility functions can be safely called from multiple threads, many DirectX operations (especially those interacting with the device context or creating resources) must be performed on the same thread that created the Direct3D device.

The freezing and 100% CPU utilization you're experiencing suggests the texture compression or conversion to BC7 format is happening on the main game thread without yielding back to the engine, effectively blocking Skyrim's rendering and update loop.

Here are some potential solutions:

1. Offload to a worker thread: Move the BC7 compression to a background worker thread, but be careful to avoid DirectX calls that must occur on the main thread.
2. Implement chunked processing: If you must use the main thread, break the compression work into smaller chunks and yield between chunks.
3. Use asynchronous DirectX operations: Leverage DirectX's built-in asynchronous methods when available.
4. Pre-process your textures: Consider having the BC7 compression happen beforehand rather than at runtime.
5. Use a different compression format: BC7 is computationally expensive. Consider using BC1/BC3 for better performance if quality trade-offs are acceptable.

Would you be willing to share a snippet of the code handling the texture generation? That would help identify the specific threading issue.

Here is the complete source. Analyse it for the above problems. My intention is to eventually add the capability to capture multiframe GIF images of variable length 0 to 30 seconds. To work with the GIF multi frame code the game loop must continue to run while the frames are generated. I am using the BC7 format as a crude test to the latency functionality before trying to add the gif section.

After analyzing your code, I've identified the issue that's causing your SKSE plugin to freeze when generating BC7 format DDS images. This is critical to fix, especially for your planned GIF recording feature which will need a smooth running game loop.

The Problem

The primary issue is in your SaveScreenshotAsDDS function, specifically with the BC7 compression:

cpp

hr = DirectX::Compress( scratchImage.GetImages(), scratchImage.GetImageCount(), scratchImage.GetMetadata(), image.format, flags, DirectX::TEX_THRESHOLD_DEFAULT, compressedImage);

This BC7 compression operation:

1. Is computationally intensive, especially without the QUICK flag
2. Executes entirely on the calling thread without yielding control
3. Is blocking the game's main thread even in your latent implementation

While you've nicely broken up the setup work into steps in your latent implementation, the actual compression work in step 4 is still done in one large blocking operation.

DirectXTK Thread Safety

Regarding thread safety:

1. DirectXTK's image processing functions are generally thread-safe for reading
2. However, the Compress function with TEX_COMPRESS_PARALLEL is using its own thread pool internally, which is causing high CPU utilization
3. The issue isn't thread safety per se, but rather thread blocking - the game thread is waiting for this operation to complete

Solutions

Here are two approaches to fix this issue:

Option 1: Use a Dedicated Worker Thread

cpp

// In your latent callback, case 4, replace the direct call with: case 4: { std::string imageTypeLower = state->imageType; std::transform(imageTypeLower.begin(), imageTypeLower.end(), imageTypeLower.begin(), ::tolower); if (imageTypeLower == "dds") { // Create a separate thread for the DDS saving operation std::thread workerThread([state]() { state->result = SaveScreenshotAsDDS( state->d3dDevice.Get(), state->d3dContext.Get(), state->desktopImage.Get(), state->basePath, state->ddsCompressionType ); // Schedule the completion notification on the main thread SKSE::GetTaskInterface()->AddTask([state]() { // Notify Papyrus here when complete SKSE::log::info("Screenshot result: {}", state->result); // Call your Papyrus callback here }); }); workerThread.detach(); // Let it run independently return; // Don't break - we'll notify completion in the worker thread } else { // Non-DDS format handling as before state->result = SaveScreenshotWithWIC(...); } break; }

Option 2: Implement Chunked BC7 Compression

This is more complex but would give you better control. You'd need to modify DirectXTK's compression to work in chunks, or implement your own chunked compression process. This would involve:

1. Breaking the image into tiles
2. Compressing one tile at a time
3. Yielding back to the game between tiles
4. Reassembling the final compressed image

Additional Recommendations

1. Always use BC7_QUICK mode for testing: For now, you could force the TEX_COMPRESS_BC7_QUICK flag to reduce processing time while you implement a better solution.
2. Use a different format for GIF preview: Consider using BC1 or uncompressed for your real-time GIF preview and only use BC7 for the final output.
3. Explicitly control thread affinity: Set the worker thread to use specific CPU cores to avoid competing with the game thread.

For your multi-frame GIF implementation, I recommend a producer-consumer pattern where:

• One thread captures frames and adds them to a queue
• Another thread processes the frames from the queue
• The game loop continues running uninterrupted

Would you like me to elaborate on any of these solutions or provide more specific code examples for your GIF recording feature?

Integration with Your Existing Code

To add this to your current plugin:

1. Add the GifRecordingState class to your code
2. Implement the StartGifRecording and StopGifRecording functions
3. Register them with Papyrus:

cpp

// In your RegisterPapyrusFunctions vm->RegisterFunction("StartGifRecording", "PrintScreenNS", StartGifRecording, true); vm->RegisterFunction("StopGifRecording", "PrintScreenNS", StopGifRecording);

Papyrus Script Example

papyrus

Scriptname GifRecordingScript extends Quest ; Import functions Function StartGifRecording(string basePath, int frameRate, int maxDuration) global native Function StopGifRecording() global native ; Example usage Function StartRecording() string basePath = "C:\\Screenshots" int frameRate = 15 ; 15 FPS int maxDuration = 10 ; 10 seconds max ; Start recording with callback to this script StartGifRecording(self as Form, basePath, frameRate, maxDuration) EndFunction ; Callback function that will be called when recording completes Function OnGifRecordingComplete(string result) Debug.Notification("GIF Recording complete: " + result) EndFunction

Key Features of This Implementation

1. Non-blocking design: Game thread only schedules short frame captures
2. Producer-Consumer Pattern: Main game thread captures frames, worker thread processes them
3. Proper resource management: All DirectX and WIC resources are properly cleaned up
4. Adaptive frame rate: Can adjust to match the game's performance
5. Progress tracking: Monitors recording duration and can auto-stop

This implementation ensures that your game loop remains responsive during GIF recording, solves the thread blocking issues you encountered with BC7 compression, and provides a foundation for multi-frame capture that can be extended for other formats in the future.

Integration Guide for GIF Recording Code

You should integrate the GIF recording code into your existing plugin.cpp file following these steps:

Step 1: Add the GifRecordingState Class

Add the GifRecordingState class after your existing PrintScreenState class but before the helper functions. This should be around line 69 in your code, right after the closing brace of the PrintScreenState class:

cpp

//============================================================================== // PrintScreenState: Class to maintain state between frames for latent functions //============================================================================== class PrintScreenState { // ... your existing code ... }; //============================================================================== // GifRecordingState: Class to manage state for multi-frame GIF capture //============================================================================== class GifRecordingState { // ... GIF recording state code from my previous message ... };

Step 2: Add the GIF Recording Functions

Add the StartGifRecording and StopGifRecording functions after your existing implementation functions but before the plugin constants and Papyrus registration. This should be right after PrintScreenLatentCallback:

cpp

static void PrintScreenLatentCallback(std::shared_ptr<PrintScreenState> state) { // ... your existing code ... } //============================================================================== // StartGifRecording: Begins a multi-frame GIF recording //============================================================================== static bool StartGifRecording( RE::StaticFunctionTag*, RE::VMHandle callbackHandle, // ... rest of the StartGifRecording function ... ) { // ... implementation from my previous message ... } //============================================================================== // StopGifRecording: Stops an active GIF recording //============================================================================== static bool StopGifRecording( RE::StaticFunctionTag* ) { // ... implementation from my previous message ... } //============================================================================== // Define plugin constants //============================================================================== namespace { const char* PLUGIN_NAME = "PrintScreen"; // ... rest of your constants ... }

Step 3: Register the GIF Recording Functions with Papyrus

Modify your RegisterPapyrusFunctions function to include the new GIF recording functions:

cpp

static bool RegisterPapyrusFunctions(RE::BSScript::IVirtualMachine* vm) { // Normal function registration vm->RegisterFunction("PrintScreen", "PrintScreenNS", PrintScreenImpl); // Register latent function - adapt as needed for your version of CommonLibSSE vm->RegisterFunction("PrintScreenLatent", "PrintScreenNS", PrintScreenImplLatent, true); // Register GIF recording functions vm->RegisterFunction("StartGifRecording", "PrintScreenNS", StartGifRecording, true); // true for latent function vm->RegisterFunction("StopGifRecording", "PrintScreenNS", StopGifRecording); SKSE::log::info("Registered PrintScreen, PrintScreenLatent, and GIF recording Papyrus functions."); return true; }

Step 4: Implement Session Tracking for Multiple Recordings

You'll need to add a global map to track active recording sessions. Add this before the plugin constants:

cpp

//============================================================================== // Global session tracking //============================================================================== namespace { // Map to track active recording sessions - can use a simple counter for IDs static std::map<uint32_t, std::shared_ptr<GifRecordingState>> g_activeRecordings; static std::mutex g_recordingsMutex; static uint32_t g_nextSessionId = 1; } // Then update the StartGifRecording function to store the state: uint32_t sessionId = 0; { std::lock_guard<std::mutex> lock(g_recordingsMutex); sessionId = g_nextSessionId++; g_activeRecordings[sessionId] = state; } // And update StopGifRecording to find and stop all sessions: static bool StopGifRecording(RE::StaticFunctionTag*) { std::lock_guard<std::mutex> lock(g_recordingsMutex); for (auto& [id, state] : g_activeRecordings) { state->Stop(); } return !g_activeRecordings.empty(); }

Step 5: Include Required Headers

Add these headers at the top of your file (after your existing includes):

cpp

#include <atomic> #include <condition_variable> #include <queue> #include <thread>

Step 6: Create Papyrus Scripts

Create a new Papyrus script file (e.g., GifRecording.psc) in your mod:

papyrus

Scriptname PrintScreenNS ; Normal screenshot functions (your existing ones) String Function PrintScreen(int validate, String basePath, String imageType, float compression, String ddsCompressionType) global native bool Function PrintScreenLatent(int validate, String basePath, String imageType, float compression, String ddsCompressionType) global native ; GIF recording functions bool Function StartGifRecording(Form callbackHandler, String basePath, int frameRate, int maxDuration) global native bool Function StopGifRecording() global native

This integration approach maintains the structure of your existing code while adding the new GIF recording functionality. The implementation uses the same design patterns and style as your existing code, making it feel like a natural extension rather than a separate piece.

well i want to provide a single keypress operation where I select Multi-fram gif operation and pass the legnth of time in seconds as a constant set in the MCM. This requires adding multi-FrameGif to image type and adding a new paramiter "duration" to the printscreen function.

Integrating Multi-Frame GIF Support with Existing Functionality

Instead of adding separate functions, I'll show you how to integrate the GIF recording capability directly into your existing PrintScreen functions. This approach will:

1. Add multi-frame GIF support as an option in your image type
2. Add a duration parameter to your existing functions
3. Keep the same function names for easier MCM integration

Step 1: Modify your PrintScreenState class

Expand your existing PrintScreenState class to include GIF recording state:

cpp

class PrintScreenState { public: // Existing input parameters int validate; std::string basePath; std::string imageType; float compression; std::string ddsCompressionType; // Add new parameter for GIF duration int gifDuration; // Existing state variables Microsoft::WRL::ComPtr<ID3D11Device> d3dDevice; Microsoft::WRL::ComPtr<ID3D11DeviceContext> d3dContext; Microsoft::WRL::ComPtr<IDXGIDevice> dxgiDevice; Microsoft::WRL::ComPtr<IDXGIAdapter> dxgiAdapter; Microsoft::WRL::ComPtr<IDXGIOutput> dxgiOutput; Microsoft::WRL::ComPtr<IDXGIOutput1> dxgiOutput1; Microsoft::WRL::ComPtr<IDXGIOutputDuplication> deskDuplication; Microsoft::WRL::ComPtr<IDXGIResource> desktopResource; Microsoft::WRL::ComPtr<ID3D11Texture2D> desktopImage; Microsoft::WRL::ComPtr<ID3D11Texture2D> stagingTex; // Add GIF-specific variables IWICBitmapEncoder* gifEncoder; IWICStream* stream; std::chrono::steady_clock::time_point gifStartTime; int frameCount; bool isRecordingGif; std::string gifFilePath; bool comInitialized; IWICImagingFactory* factory; int currentStep; std::string result; RE::VMHandle handle; PrintScreenState( int _validate, const std::string& _basePath, const std::string& _imageType, float _compression, const std::string& _ddsCompressionType, int _gifDuration = 0) : validate(_validate) , basePath(_basePath) , imageType(_imageType) , compression(_compression) , ddsCompressionType(_ddsCompressionType) , gifDuration(_gifDuration) , gifEncoder(nullptr) , stream(nullptr) , frameCount(0) , isRecordingGif(false) , comInitialized(false) , factory(nullptr) , currentStep(0) {} ~PrintScreenState() { // Clean up GIF resources if (gifEncoder) { gifEncoder->Release(); gifEncoder = nullptr; } if (stream) { stream->Release(); stream = nullptr; } if (factory) { factory->Release(); factory = nullptr; } if (comInitialized) { CoUninitialize(); comInitialized = false; } } };

Step 2: Update function signatures to include duration parameter

cpp

// Update the PrintScreenImpl signature static std::string PrintScreenImpl( RE::StaticFunctionTag*, int validate, const std::string& basePath, const std::string& imageType, float compression, const std::string& ddsCompressionType, int gifDuration = 0 // New parameter with default value ) { // Existing implementation... } // Update the PrintScreenImplLatent signature static bool PrintScreenImplLatent( RE::StaticFunctionTag*, RE::VMHandle handle, int validate, const std::string& basePath, const std::string& imageType, float compression, const std::string& ddsCompressionType, int gifDuration = 0 // New parameter with default value ) { // Create state object with new parameter auto state = std::make_shared<PrintScreenState>( validate, basePath, imageType, compression, ddsCompressionType, gifDuration); state->handle = handle; // Existing implementation... }

Step 3: Add GIF recording functions

Add these helper functions for GIF recording:

cpp

//============================================================================== // InitializeGifRecording: Sets up a new GIF recording session //============================================================================== static std::string InitializeGifRecording(PrintScreenState* state) { try { std::string imageTypeLower = state->imageType; std::transform(imageTypeLower.begin(), imageTypeLower.end(), imageTypeLower.begin(), ::tolower); if (imageTypeLower != "gif") { return "Not a GIF recording"; } // Create output file path std::ostringstream oss; oss << state->basePath; if (state->basePath.back() != '\\' && state->basePath.back() != '/') { oss << "\\"; } oss << "recording_"; auto now = std::chrono::system_clock::now(); auto t = std::chrono::system_clock::to_time_t(now);

} } //============================================================================== // AddFrameToGif: Captures and adds a frame to the GIF //============================================================================== static std::string AddFrameToGif(PrintScreenState* state) { try { if (!state->isRecordingGif) { return "Not recording a GIF";

} // Capture frame DXGI_OUTDUPL_FRAME_INFO frameInfo{}; Microsoft::WRL::ComPtr<IDXGIResource> desktopResource; HRESULT hr = state->deskDuplication->AcquireNextFrame( 100, // Short timeout &frameInfo, &desktopResource ); if (FAILED(hr)) { // Not a fatal error, just skip this frame return "Continue"; } // Get the desktop image Microsoft::WRL::ComPtr<ID3D11Texture2D> desktopImage; hr = desktopResource->QueryInterface(IID_PPV_ARGS(&desktopImage)); state->deskDuplication->ReleaseFrame(); if (FAILED(hr)) { return "Failed to get desktop image"; } // Get texture description D3D11_TEXTURE2D_DESC texDesc; desktopImage->GetDesc(&texDesc); // Create staging texture if needed if (!state->stagingTex) { D3D11_TEXTURE2D_DESC stagingDesc = texDesc; stagingDesc.Usage = D3D11_USAGE_STAGING; stagingDesc.BindFlags = 0; stagingDesc.CPUAccessFlags = D3D11_CPU_ACCESS_READ; stagingDesc.MiscFlags = 0; hr = state->d3dDevice->CreateTexture2D(&stagingDesc, nullptr, &state->stagingTex); if (FAILED(hr)) { return "Failed to create staging texture"; } } // Copy resource to staging texture state->d3dContext->CopyResource(state->stagingTex.Get(), desktopImage.Get()); // Map the staging texture to get access to pixel data D3D11_MAPPED_SUBRESOURCE mapped; hr = state->d3dContext->Map( state->stagingTex.Get(), 0, D3D11_MAP_READ, 0, &mapped ); if (FAILED(hr)) { return "Failed to map staging texture"; } // Create a bitmap from the frame data Microsoft::WRL::ComPtr<IWICBitmap> wicBitmap; hr = state->factory->CreateBitmapFromMemory( texDesc.Width, texDesc.Height, GUID_WICPixelFormat32bppBGRA, mapped.RowPitch, mapped.RowPitch * texDesc.Height, static_cast<BYTE*>(const_cast<void*>(mapped.pData)), &wicBitmap ); // Unmap the resource state->d3dContext->Unmap(state->stagingTex.Get(), 0); if (FAILED(hr)) { return "Failed to create bitmap from memory"; } // Handle first frame differently (contains global settings) Microsoft::WRL::ComPtr<IWICBitmapFrameEncode> frameEncode; Microsoft::WRL::ComPtr<IPropertyBag2> propBag; // Create a new frame hr = state->gifEncoder->CreateNewFrame(&frameEncode, &propBag); if (FAILED(hr)) { return "Failed to create new frame"; } // Set properties for the first frame if (state->frameCount == 0) { PROPBAG2 option = {}; VARIANT value; VariantInit(&value); // Set logical screen size option.pstrName = L"LogicalScreenWidth"; value.vt = VT_UI2; value.uiVal = static_cast<USHORT>(texDesc.Width); hr = propBag->Write(1, &option, &value); option.pstrName = L"LogicalScreenHeight"; value.vt = VT_UI2; value.uiVal = static_cast<USHORT>(texDesc.Height); hr = propBag->Write(1, &option, &value); // Enable looping option.pstrName = L"Loop"; value.vt = VT_BOOL; value.boolVal = VARIANT_TRUE; hr = propBag->Write(1, &option, &value); VariantClear(&value); } // Initialize the frame hr = frameEncode->Initialize(propBag.Get()); if (FAILED(hr)) { return "Failed to initialize frame encode"; } // Set frame dimensions hr = frameEncode->SetSize(texDesc.Width, texDesc.Height); if (FAILED(hr)) { return "Failed to set frame size"; } // Set pixel format WICPixelFormatGUID pixelFormat = GUID_WICPixelFormat32bppBGRA;

if (FAILED(hr)) { return "Failed to write source bitmap"; } // Set frame delay with metadata Microsoft::WRL::ComPtr<IWICMetadataQueryWriter> metadataWriter; if (SUCCEEDED(frameEncode->GetMetadataQueryWriter(&metadataWriter))) { // Get the GIF control extension metadata writer if (SUCCEEDED(metadataWriter->GetMetadataQueryWriter(L"/grctlext", &metadataWriter))) { PROPVARIANT propDelay; PropVariantInit(&propDelay); // Set frame delay (in 100ths of a second) propDelay.vt = VT_UI2; propDelay.uiVal = 10; // 0.1 seconds hr = metadataWriter->SetMetadataByName(L"/grctlext/Delay", &propDelay); PropVariantClear(&propDelay); } } // Commit the frame hr = frameEncode->Commit(); if (FAILED(hr)) { return "Failed to commit frame"; } // Increment frame count state->frameCount++; return "Continue"; } catch (const std::exception& e) { return std::string("Exception during frame capture: ") + e.what(); } } //============================================================================== // FinalizeGifRecording: Completes the GIF recording and cleans up //============================================================================== static std::string FinalizeGifRecording(PrintScreenState* state) { try { if (!state->isRecordingGif) { return "Not recording a GIF"; } // Commit the GIF encoder to save the file if (state->gifEncoder) { HRESULT hr = state->gifEncoder->Commit(); if (FAILED(hr)) { return "Failed to commit GIF encoder"; } } // Clean up GIF-specific resources if (state->gifEncoder) { state->gifEncoder->Release(); state->gifEncoder = nullptr; } if (state->stream) { state->stream->Release(); state->stream = nullptr; } // Mark as no longer recording state->isRecordingGif = false; return "Success: GIF saved with " + std::to_string(state->frameCount) + " frames"; } catch (const std::exception& e) { return std::string("Exception during GIF finalization: ") + e.what(); } }

Step 4: Modify the PrintScreenLatentCallback to handle GIF recording

Update your PrintScreenLatentCallback function to handle the GIF recording process:

cpp

static void PrintScreenLatentCallback(std::shared_ptr<PrintScreenState> state) { // Process latent work in this callback switch (state->currentStep) { case 0: { // Validation step if (state->validate == 1) { state->result = Check_Path(state->basePath, state->imageType); break; } // Format validation std::string imageTypeLower = state->imageType; std::transform(imageTypeLower.begin(), imageTypeLower.end(), imageTypeLower.begin(), ::tolower); if (imageTypeLower != "bmp" && imageTypeLower != "jpg" && imageTypeLower != "jpeg" && imageTypeLower != "png" && imageTypeLower != "gif" && imageTypeLower != "tif" && imageTypeLower != "tiff" && imageTypeLower != "dds") { state->result = "Unsupported image format: " + state->imageType; break; } // Initialize COM state->comInitialized = SUCCEEDED(CoInitializeEx(nullptr, COINIT_MULTITHREADED)); HRESULT hr = CoCreateInstance( CLSID_WICImagingFactory, nullptr, CLSCTX_INPROC_SERVER, IID_PPV_ARGS(&state->factory) ); if (FAILED(hr)) { if (state->comInitialized) CoUninitialize(); state->result = "Failed to create WIC Imaging Factory. HRESULT: " + std::to_string(hr); break; } // Move to next step state->currentStep = 1; SKSE::GetTaskInterface()->AddTask([state]() { PrintScreenLatentCallback(state); }); return; } case 1: { // Initialize D3D11 UINT flags = D3D11_CREATE_DEVICE_BGRA_SUPPORT; #ifdef _DEBUG flags |= D3D11_CREATE_DEVICE_DEBUG; #endif D3D_FEATURE_LEVEL featureLevel; HRESULT hr = D3D11CreateDevice( nullptr, D3D_DRIVER_TYPE_HARDWARE, nullptr, flags, nullptr, 0, D3D11_SDK_VERSION, &state->d3dDevice, &featureLevel, &state->d3dContext ); if (FAILED(hr)) { state->result = "Failed to create D3D11 device. HRESULT: " + std::to_string(hr); break; } // Move to next step state->currentStep = 2; SKSE::GetTaskInterface()->AddTask([state]() { PrintScreenLatentCallback(state); }); return; } case 2: { // Setup DXGI HRESULT hr = state->d3dDevice.As(&state->dxgiDevice); if (FAILED(hr)) { state->result = "Failed to get DXGI device. HRESULT: " + std::to_string(hr); break; } hr = state->dxgiDevice->GetAdapter(&state->dxgiAdapter); if (FAILED(hr)) { state->result = "Failed to get DXGI adapter. HRESULT: " + std::to_string(hr); break; } hr = state->dxgiAdapter->EnumOutputs(0, &state->dxgiOutput); if (FAILED(hr)) { state->result = "Failed to enumerate DXGI outputs. HRESULT: " + std::to_string(hr); break; } hr = state->dxgiOutput.As(&state->dxgiOutput1); if (FAILED(hr)) { state->result = "Failed to get DXGI Output1. HRESULT: " + std::to_string(hr); break; } // Move to next step state->currentStep = 3; SKSE::GetTaskInterface()->AddTask([state]() { PrintScreenLatentCallback(state); }); return; } case 3: { // Duplicate output and acquire frame HRESULT hr = state->dxgiOutput1->DuplicateOutput(state->d3dDevice.Get(), &state->deskDuplication); if (FAILED(hr)) { state->result = "Failed to duplicate output. HRESULT: " + std::to_string(hr); break; } // Check if we're doing multi-frame GIF recording std::string imageTypeLower = state->imageType; std::transform(imageTypeLower.begin(), imageTypeLower.end(), imageTypeLower.begin(), ::tolower); if (imageTypeLower == "gif" && state->gifDuration > 0) { // Initialize GIF recording state->result = InitializeGifRecording(state); if (state->result != "Success") { break; } // Move to the GIF recording step state->currentStep = 5; SKSE::GetTaskInterface()->AddTask([state]() { PrintScreenLatentCallback(state); }); return; } // For single frame captures, continue with normal flow DXGI_OUTDUPL_FRAME_INFO frameInfo{}; hr = state->deskDuplication->AcquireNextFrame(500, &frameInfo, &state->desktopResource); if (FAILED(hr)) { state->result = "Failed to acquire next frame. HRESULT: " + std::to_string(hr); break; } hr = state->desktopResource->QueryInterface(IID_PPV_ARGS(&state->desktopImage)); if (FAILED(hr)) { state->deskDuplication->ReleaseFrame(); state->result = "Failed to get desktop image texture. HRESULT: " + std::to_string(hr); break; } state->deskDuplication->ReleaseFrame(); // Move to next step state->currentStep = 4; SKSE::GetTaskInterface()->AddTask([state]() { PrintScreenLatentCallback(state); }); return; } case 4: { // Save the single screenshot std::string imageTypeLower = state->imageType; std::transform(imageTypeLower.begin(), imageTypeLower.end(), imageTypeLower.begin(), ::tolower); if (imageTypeLower == "dds") { state->result = SaveScreenshotAsDDS( state->d3dDevice.Get(), state->d3dContext.Get(), state->desktopImage.Get(), state->basePath, state->ddsCompressionType ); } else { state->result = SaveScreenshotWithWIC( state->d3dDevice.Get(), state->d3dContext.Get(), state->desktopImage.Get(), state->factory, state->basePath, state->imageType, state->compression ); } break; } case 5: { // GIF recording loop // Add a frame to the GIF state->result = AddFrameToGif(state); // If we need to continue recording, schedule the next frame capture if (state->result == "Continue") { // Calculate frame delay based on target frame rate (default 10 FPS) float frameDelay = 100.0f; // 100ms = 10 FPS // Schedule next frame capture SKSE::GetTaskInterface()->AddTaskDelayed([state]() { PrintScreenLatentCallback(state); }, frameDelay / 1000.0f); // Convert ms to seconds return; } else if (state->result.substr(0, 7) != "Success") { // Error occurred during recording SKSE::log::error("GIF recording error: {}", state->result); break; } // If we got here, recording is complete break; } } // We're done - notify Papyrus SKSE::log::info("Screenshot result: {}", state->result); // Here you would add code to return the result to Papyrus // For example, call a callback function on the Papyrus object }

Step 5: Update the Papyrus script to expose the new parameter

papyrus

Scriptname PrintScreenNS ; Updated functions with gifDuration parameter String Function PrintScreen(int validate, String basePath, String imageType, float compression, String ddsCompressionType, int gifDuration = 0) global native bool Function PrintScreenLatent(int validate, String basePath, String imageType, float compression, String ddsCompressionType, int gifDuration = 0) global native

Step 6: Create an MCM script for your mod to set GIF duration

papyrus

Scriptname MyScreenshotMCM extends SKI_ConfigBase ; MCM properties int property GifDuration = 5 auto ; MCM initialization event OnConfigInit() Pages = new string[1] Pages[0] = "Settings" endEvent ; MCM page setup event OnPageReset(string page) if (page == "Settings") SetCursorFillMode(TOP_TO_BOTTOM) AddHeaderOption("Screenshot Settings") AddSliderOption("GIF Recording Duration", GifDuration, "{0} seconds") endif endEvent ; Handle slider changes event OnSliderOptionSliderOpen(string option) if (option == "GIF Recording Duration") SetSliderDialogStartValue(GifDuration) SetSliderDialogDefaultValue(5) SetSliderDialogRange(1, 30) SetSliderDialogInterval(1) endif endEvent event OnSliderOptionSliderAccept(string option, float value) if (option == "GIF Recording Duration") GifDuration = value as int SetSliderOptionValue(option, GifDuration, "{0} seconds") endif endEvent

Step 7: Example hotkey script for single-key operation

papyrus

Scriptname ScreenshotHotkey extends SKI_QuestBase import Debug import PrintScreenNS ; Reference to the MCM MyScreenshotMCM property MCM auto ; Hotkey registration event OnInit() RegisterForKey(157) ; F6 for screenshot RegisterForKey(158) ; F7 for GIF recording endEvent ; Hotkey handler event OnKeyDown(int keyCode) if (keyCode == 157) ; F6 TakeScreenshot(false) elseif (keyCode == 158) ; F7 TakeScreenshot(true) endif endEvent ; Screenshot function function TakeScreenshot(bool isGif) string basePath = "C:\\Skyrim\\Screenshots" string imageType = isGif ? "gif" : "png" int gifDuration = isGif ? MCM.GifDuration : 0 if (isGif) Notification("Starting GIF recording for " + gifDuration + " seconds...") bool success = PrintScreenNS.PrintScreenLatent(0, basePath, imageType, 0.85, "bc1", gifDuration) else string result = PrintScreenNS.PrintScreen(0, basePath, imageType, 0.85, "bc1") Notification("Screenshot taken: " + result) endif endFunction

This approach integrates multi-frame GIF recording directly into your existing functions, maintaining your original design pattern while adding the new capability. The user can now select "gif" as the image type and specify a duration, and the function will handle single-frame or multi-frame capture accordingly.

How to Use The GIF Recording Feature

Here's a Papyrus script example showing how to use the updated plugin for both single screenshots and multi-frame GIF recording:

papyrus

Scriptname PrintScreenNS ; Updated function signatures with gifDuration parameter String Function PrintScreen(int validate, String basePath, String imageType, float compression, String ddsCompressionType, int gifDuration = 0) global native bool Function PrintScreenLatent(int validate, String basePath, String imageType, float compression, String ddsCompressionType, int gifDuration = 0) global native ; Event that will be triggered when PrintScreenLatent completes Event OnScreenshotComplete(String result) EndEvent

These changes integrate multi-frame GIF recording into your existing SKSE plugin without changing its core functionality. Now you can take still screenshots with the original function or record animated GIFs with a single keypress using the same interface.
