Transcode fails after a few hours
Posted: 13 Jul 2011 16:11
Hello community,
I am running a setup where I use VLC to transcode a number of web-radio channels to multicast using VLC. However, these transcodes start to fail after a number of hours (typically 3-5 but sometimes much less) with the following error types:
The error is logged many, many times in the log (of course the number in paranthesis changes). The only way to recover from the problem appears to be to completely restart the VLC process.
Here is an example of the configuration used to encode the stream:
/etc/vlc/radiotest.conf
The channel in question is publicly available as linked above, in case anyone feels like testing.
The VLC version used is this (I have removed the debian-multimedia repository as described on these forums):
Here is a log of the VLC starting up, and failing after a while:
I currently have a hack in place that scans the recent log files for "late buffer for mux input" and restarts the player when it happens. But obviously that is an ugly non-solution, so hopefully someone can help me understand what is going wrong and what I might change to fix it.
I will be happy to provide any information I have neglected.
