VLM single input, multi-output from live IP source
Posted: 15 Mar 2007 18:20
Hi,
A friend and I are trying to setup a streaming service. Our goal is to receive from an Mpeg4 IP video source (an Axis 210A IP camera) and re-encode into 3 separate bit rates. The re-encoded streams will then be served out on different ports for clients to view depending on their connection speed.
In order to do this we used VLC's VLM interface and a batch file that is created on the fly from a customised web GUI.
Contents of the batch file are as follows:
We have tried VLC versions 0.8.6a and 0.9.0-svn on Windows XP with minimal success. On accessing the output streams using VLC or WMP on client PCs we sometimes get just video, or just audio or both or nothing!? 
One of the major errors that we see is: "ffmpeg encoder warning: almost fed libavcodec with a frame in the past".
We have also tried to rectify this error by recompiling VLC 0.8.6a according to advice given in this thread: viewtopic.php?p=95377#95377
However we still have the same error. Can anyone help us with this error, or advise on an alternative method to achieve our goal.
Thanks in advance.
