[Ffmpeg-devel] [PATCH]: palette to rgb32 with alpha need to make sure transparency is set to zero

[Karl H. Beckers]

Hi,
haven't solved my original problem with my color planes, but found out why
converting frames from PAL8 to png files via PIX_FMT_ARGB32 yielded images
that could be converted to animated gifs with animate perfectly well, but
which would show nothing in eog. The alpha channel was broken (and
apparently dumped by animate).
Using PIX_FMT_RGB24 or this patch to libswscale/rgb2rgb.c solves it.

Cheers,

Karl.
