Black Screen Capture Fix & Audio Buzz Elimination

  • WGC HDR Tonemapping & Safe Subresource Region Copying: Restored safe CopySubresourceRegion texture bounds handling and tonemapper processing for Windows Graphics Capture (WGC), eliminating black screen captures when recording HDR displays or window surfaces with dimensional padding and borders.
  • DXGI Output Format Hardening: Updated DXGI Desktop Duplication format validation to support SDR DXGI_FORMAT_B8G8R8A8_UNORM even on HDR-enabled displays, and dynamically detected capture formats to avoid false capture failures.
  • Capture Frame Lifecycle & COM Pointer Isolation: Scoped captured frame handles and presentation timestamps strictly to the execution lifecycle of EncoderWorker::run(), preventing stale texture pointers from previous capture sessions from leaking into new recordings.
  • Continuous Audio Loopback Silence Filling: Restored continuous silent packet generation during periods of silence in WASAPI loopback capture (both system and game process loopback). This preserves a strictly continuous, monotonic audio PTS timeline, completely eliminating the timestamp stalls that previously forced the live AAC encoder to restart with audible buzzing, clicking, and crackling artifacts.
