Hi.

I can't encode any video using the mp2v codec on Debian unstable. All i got is a segmentation fault, with no other error messages. Did anyone ever got that problem?

Thanks for help.

What's your input ?
launch vlc with -vvv and give us the last messages.

I got the same problem, when trying to unicast a div3 to a mpeg2 reader via UDP (the UDP/MPEG-TS part is not responsible for the fault, since trying to transcode to disc leads to the same result).

Here is the sout chain :
:sout=#transcode{vcodec=mp2v,vb=1024,scale=1,fps=25,acodec=mpga,ab=192,channels=2}:duplicate{dst=std{access=udp,mux=ts,url=freeplayer.freebox.fr:1234}}

(fps=25 is here to avoid a message "current codec does not support 100000/39999 fps")

Last messages are :

I hope this will help to sort out the problem.
