[FFmpeg-devel] [PATCH 2/2] fftools/ffprobe: 240M matrix is not the same as BT.601

[Valerii Zapodovnikov]

I am sorry, what? It converts to 420 always? Wow? But you are right. This
is a problem that colors are wrong after YUV444 - > YUV420 -> RGB. It
selects BT.709 matrix even if BT.601 matrix is requested, this can be fixed
by "ffplay -vf scale=in_color_matrix=auto,format=gbrp" or just by using
mpv. Maybe I need to further test VUI vs -movflags +write_colr vs what my
samples use.
