As discussed in https://trac.ffmpeg.org/ticket/8454, if possible the dshow
filter should provide information about the color range, color space,
primaries, trc and chroma location of the frames a device provides. Some
DirectShow devices do provide this information. I open an issue here with
a partial patch, as a starting point and for discussion, before i send it
to the list. I need help with the following:
1. Check that my conversion from DXVA color information to FFmpeg's
AVColorRange, AVColorPrimaries and AVColorTransferCharacteristic is
correct.
2. Help to convert the DXVA color information to AVColorSpace
3. Advice on how to provide this information to FFmpeg/the user. As far as
i understand, this is not normally provided by the format, but by the
codec, which (I think) it outside the purview of dshow/a format.
Thanks!
