[FFmpeg-devel] [PATCH] lavf/apngdec: use AVStream.time_base instead of r_frame_rate

[James Almer]

Should fix framedrops on some apng files

This is still not optimal because the value of time_base will be updated on every frame, 
and in some cases delay_num and delay_den varies between frames.

Better fix welcome.
