The VideoLAN Forums

I have made some tests with rtsp running first via command prompt
vlc --ttl 12 -vvv --color -I telnet --telnet-password videolan --rtsp-host 0.0.0.0:554
Then go to http interface an add streaming videos, i have the vlc server (vlc-0.8.6-svn-20060813-0000-win32.exe) in windows box, i can run the streams via rtsp in the mac osx 10.4, everything works fine, but when i try to transcode, doesn't work, vlc client in mac crash sometimes or just play audio, here is the message

What am i doing wrong?

I'll have to check the way the http interface handles transcoding Video on Demand media items. There might be a small bug. I'll reply to this thread once i've done so (this week end i guess).
