Re: Creating a Demultiplexer for Mime Encoded streams

Thanks ! Seems like most of the demux2 have a couple of main methods: Open and Close Capabilities (demux2), Categories(I/p) sub categories (I/P demux) are also registered for each demux module Codecs are set using 4CCs There is a score set for each demux2.

Re: Panasonic Camera Streaming MJPEG Video with G.726 Audio

The dumped stream can be read using the asf container by VLC. The live mime encoded stream cannot be read since there are no appropriate demuxers.
