 Summary of the bug:
 If I use the newest version to encode a gif to an av1 webm it will choose
 gbrp which is great because it keeps the colours the same. It also decodes
 fine in Chromium and mpv.
 However in VLC and ffplay white becomes pink and it all looks horrible.
 Same when decoding into another format with ffmpeg.
 I don't know whether this also affects rgb av1 in other containers like
 mkv or mp4.

 How to reproduce:
 {{{
 % ffmpeg -i input.gif -c:v av1 output.webm
 % ffmpeg -i output.webm pink.gif
 }}}
