[FFmpeg-user] segfault in ffmpeg when including yadif in chain

[Misha Penkov]

Hi,

I'm trying to deinterlace a 1440x1080 interlaced video.
Unfortunately, the ffmpeg executable segfaults:

$ ~/git-ext/ffmpeg/ffmpeg -i 1440x1080i.avi -vf yadif -y output.avi

Segmentation fault

What could be the problem?  How can I work around the segfault?

The video is approx. 17MB, so I can provide it if required.

Cheers,
