[FFmpeg-user] TGA File color looks incorrect when converted to H.264

Tue Apr 6 22:47:52 EEST 2021

What color space is your image created in? A first guess is that if it has
an embedded color space that isn't what ffmpeg expects, it could cause the
failure. Can you convert it to use sRGB, which at a guess would be more
familiar to ffmpeg?

(Note, I'm making guesses based on some knowledge of color spaces and the
type of problems that arise when they're not handled properly or are not
specified, not from a knowledge of ffmpeg).
