[vlc-devel] How to trim/cut clips with VLC

[zhu shi song]

I using the following command to transcode one piece of video from start-time to stop-time.

vlc hzvideo.wmv --start-time=10 --stop-time=20 --sout=#transcode{vcodec=h264, venc=x264{preset=veryfast}, vb=0,scale=0,acodec=mp4a,
ab=128,channels=2,samplerate=44100}:file{dst='11.mp4'}

when reaching stop-time, the transcoding ended.  But start-time had no effect, it always started from the beginning.  What's wrong with it?
Thanks
