Hi.
Several users are reporting rendering crashes in Ubuntu 11.10 using sunab's
packages.
I noticed that the official FFmpeg packages in Ubuntu 11.10 are from libav,
version 0.7.3.
The avformat consumer consistently crashes with this version.
The simple patch below fixes the crash and rendering works again with that
libav 0.7.3 (the change is to use av_opt_find only if libavutil > 51.7.0)
regards
