libVLC behave differently then VLC Media Player

Postby GoldenEgg » 09 Sep 2009 16:34

Hello,
We are useing libVLC to stream 264 video over UDP but the video received very bad on the other end. When we are doing the same with the VLC Media Player things looks much better.
Any idea why? How can I debug such a case? How can I see with what parameters every session is actually running?
Thanks,
Eyal

Since you're using libvlc to stream h264 aren't you setting the configuration there? Other than that, you can check if you couldn't gleam some more info from the VLC messages at debug level 2, or perhaps the media metadata. Otherwise, if you can dump the stuff, maybe try mediainfo (google it or check on sourceforge).

Thanks for you reply.
The configuration on libvlc is set by me to be the same as in the media player (As far as I can see and control...)
I'll try the debug messages.
Does mediainfo can work with stream or do I have to save it to file?

Not as far as I know. It only works on files.

Compare the logs from both libvlc and VLC.

I compared the log file and other then obvious differences I can't see any reason for the very bad video on the libVLC application.
Does anybody have any idea for how to debug that situation?
Thanks
