[FFmpeg-devel] h264 decoding regressions

This is just a mention because I have not looked at it in detail yet.

Bunny plays fine when using SwsContext for converting from PIX_FMT_GBR24P to 
PIX_FMT_YUV420P

but doesn't appear to work when converting from PIX_FMT_GBR24P to an RGB 
format like PIX_FMT_BGRA.

I need to look at in more detail and will report it as bug if there is a 
problem, but does anyone have a heads up on this ?

This worked before when the colors were swaped, but I think now all I get is 
black when going to an RGB format. The reason I have to say 'I think' is 
because I use YUV for output when it applies, but I also use RGB formats for 
thumbnail generation. Thumbnail is all black. I will force display to goto 
RGB instead of YUV and see what happens there when I get a chance.
