[Ffmpeg-devel] trouble with h264.c

[Scott Treude]

Hello,

I'm trying to convert an h264 quicktime to a series of ppm files and I'm receiving the following error:

ffmpeg: h264.c:2316: mc_dir_part: Assertion `pic->data[0]' failed.

The command I'm using is:
/usr/local/bin/ffmpeg -ss 100  -t .2 -i myMovie.mov test%d.ppm

It seems to work fine without the -ss; so is seeking a problem with h264?

Any help would be greatly appreciate!  

Thanks,
Scott
