[vlc-devel] "late buffer for mux input" when streaming from http

[Georgi Chorbadzhiyski]

Hi all,

Once a day (or about every 12-14 hours) I get the following messages in
my logs. After the first message VLC stops serving http stream requests
and starts eating memory until kernel OOM killer kills it or I restart
the process manualy.

...7 hours later and countless such messages...

The command line used is:

  vlc -v --syslog -d http://10.0.1.157:8080 --http-caching 5000 \
   --sout '#duplicate{dst="transcode{scale=0.50,vcodec=WMV2,acodec=mp3,vb=320,ab=64}:\
           standard{access=http,mux=asf,dst=127.0.0.1:8082}"}' vlc:quit

The PC is quad core Xeon 2.8Ghz it definetely have enough CPU power, the
server that I'm streaming from is connected via gigabit interface to the
restreamer.

What's the solution to this problem. I've searched the vlc forums and I see
that couple of other guys have the same problems, but no resolution so far.

Can I force VLC to quit or somehow recover when this problem occures?
