[PATCH 0/2] MR9620: quartz: Supports yuy2 video stream rendering
the yuv2 format video stream captured from v4l requires conversion to RGB24 format for rendering.I have verified that FFmpeg-8.0.1-essentials_build supports YUV capture format under Wine.The attachment contains format support obtained using ffmpeg.exe, along with video capture data processed via yuy2. yuy2.[test_yuyv422.avi](/uploads/e09577dc5acc517d17992ea1831bce99/test_yuyv422.avi) [ffmpeg_support.log](/uploads/3fdf7ead5d679dc6bb45300797c7b664/ffmpeg_support.log) -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9620
