Hi all,
I tried to use the stabilization feature of transcode on a mjpeg avi
captured by a Nikon D90 camera (I can provide the video, if required).
Unfortunately, it crashed. The system is ubuntu 9.10, with the standard
libs. The crash occurs both with the ubuntu package and a selfcompiled
version of transcode 1.1.5. See below for a backtrace of the crash.
Is there a compatibility problem between the ffmpeg version shiped with
ubuntu? The video works fine with all other players I have tried (totem,
vlc, mplayer, ffplay).
