[FFmpeg-devel] cutting an FLV

[Cyrus A]

I'm trying to cut a small portion out of a larger FLV file. I have an 
FLV file that is 156 seconds long. The command...

ffmpeg -ss 6 -t 100 -y -vcodec copy -acodec copy -i 
/home/cyrus/Desktop/test.flv /home/cyrus/Desktop/cut.flv

...should create a file that is 94 seconds long (seeking 6 seconds, 
duration for 100 seconds). Instead, it creates a file 150 seconds long. 
That is, it seems to be seeking for 6 seconds, then giving me the rest 
of the clip. Any ideas why that's happening?
