[Ffmpeg-devel] seek with duration for cutting: broken or changed?

Hi,

Since it is a different problem, please open a new thread, with the info
requested by bugreports.html.
Also provide some pointer to your test_cut.avi file, I tried your commands
on one AVI of mine, and they worked OK (with SVN-r6798).
