Is there a general memory leak when streaming video over udp?

Using vlc to stream video over udp breaks on FreeBSD, Fedora, Red Hat, Windows and Suse on different hardware. The behaviour is similar, streaming starts, memory leaks away and when memory is low enough vlc stops.

On the *nix variants the command to run vlc is as below. all installations are fresh and the latest version of vlc is being used.

vlc -vvv --loop playlist.m3u --sout '#transcode{acodec=mpga,vb=2048,ab=192}:standard{access=udp,mux=ts,dst=239.255.255.255}'

What can I do to help?

Not one reply?

Am I the only one realizing the potential of using vlc as the engine to display video over the LAN?

Hello,
I suppose I have the same problem (but I didn't do any extensive research).
Kubuntu 6.10 + VLC 0.8.6 - udp multicast streaming - VLM or directly by vlc command. VLC is streaming till there is free memory and crashes.
Maybe this is known bug (and maybe already solved), I am going to try vlc nightbuild.

Was this problem resolved? If so what was the solution? I am having the same issues!

Thanks

I am sorry, I have not.

I have posted the issue to the FreeBSD-questions mailing list but the conclusion from there, which I tend to agree to, is that this is an issue with vlc and threads.

I have been trying to analyze the source code and I have glanced in particular at the threads parts of it and tried a few alterations but so far no luck.

hi,

just to narrow things down... i've been having the same problem but with http unicast broadcasts... It does take a while (a few days) for VLC to crash but it occasionally dies away with a segfault.

I have noticed however better behaviour in certain h/w conigurations and i'm trying to get an idea of what goes wrong at this point.

I'm sure it'll be a right pain to locate this leak. Try setting "ulimit -c unlimited" so that vlc dumps core when it crashes. I'm starting from there anyway...

hope we have news on this soon...
