Correction:
Segmentation fault also with -vf unsharp=5:5:0.5:opencl=1 previously unavailable.
comment:3 by , 12 years ago
Am I correct that no particular sample is needed to reproduce the problem?
yes segmentation fault with any video.

http://git.videolan.org/?p=ffmpeg.git;a=commitdiff;h=6354a6ce5271a32857238a8ccb2107286984feb5
fix the problem,
now -vf deshake=opencl=1 work again.
Remain the --enable-opencl ffmpeg build problem on my system,
see:
