I can't render to .mp4 so I decided to try xvid. That crashes as well. This all worked a week ago and now it doesn't. I am using Lucid Lynx Ubuntu 10.04. I am using Sunab's repo.

Apparently FFMPEG had to be updated due to some security flaw and medibuntu's version of libavformat-extras-52 was older then the ones in Ubuntu so it was using the newer versions from Ubuntu's repo instead of medibuntu's repo. Once I updated my lucid medibuntu repo to point to "lucid-staging" instead of only "lucid" it now works again being able to encode to mp4 (h264/aac). I had to update it located in

/etc/apt/sources.list.d/no-medibuntu.list

not sure what that's all about but I am just glad I can encode my youtube clips to .mp4 again.


the bug is here for anyone curious. https://bugs.launchpad.net/ubuntu/+source/ffmpeg/+bug/738134
