[FFmpeg-devel] [PATCH 0/2] avdevice/dshow: set color information in stream

[Diederick Niehorster]

These two patches check if a DirectShow device provides color
information and sets this in the AVStream. If a device provides equivalent formats with and without color information, the format with color information is used.

I'm a first-time contributor, hope all is in order.

Example output of list_options for a device supporting extended color
information, before and after this patch series:
pixel_format=yuyv422  min s=640x480 fps=5 max s=640x480 fps=30
pixel_format=yuyv422  min s=640x480 fps=5 max s=640x480 fps=30 (tv, bt470bg/bt709/unknown, topleft)

vcodec=h264  min s=640x480 fps=5 max s=640x480 fps=30
vcodec=h264  min s=640x480 fps=5 max s=640x480 fps=30 (tv, bt470bg/bt709/unknown, topleft)

vcodec=mjpeg  min s=1920x1080 fps=5 max s=1920x1080 fps=30
vcodec=mjpeg  min s=1920x1080 fps=5 max s=1920x1080 fps=30 (pc, bt470bg/bt709/unknown, center)
