You should really report the FFmpeg issue to them together with a sample
file.
But otherwise, instead of decoding to images you'd normally use mplayer
with -vo yuv4mpeg which will preserve frame rate and aspect settings,
and ideally you'd stream it to ffmpeg via a pipe to not require so much
disk space.
