Hi if I encode a movie in the targa format with the bgra profile the movie is unreadable by every software using quicktime as a backend.
Movie is perfectly readable by mpv thought but that's not helping us ;-)
the command line used is
-r 25 -vcodec targa -pix_fmt bgra -metadata:s encoder="TGA" -vendor apl0 -acodec pcm_s16le -f mov'
I link below a source file and an "unreadable movie and a working one encoded by the quicktime codec.
If it's a regression anybody is able to tell us which build is ok ?
It's going to be a problem for us because like I've reported last week the prores encoder fail with an alpha channel, the dnxhd too, there is none of the "VFX" industry video codec working with an alpha channel with ffmpeg ;-)
