Detailed Description

Interplay MVE file demuxer by Mike Melanson (melan.nosp@m.son@.nosp@m.pcisy.nosp@m.s.ne.nosp@m.t) For more information regarding the Interplay MVE file format, visit: http://www.pcisys.net/~melanson/codecs/ The aforementioned site also contains a command line utility for parsing IP MVE files so that you can get a good idea of the typical structure of such files.

This demuxer is not the best example to use if you are trying to write your own as it uses a rather roundabout approach for splitting up and sending out the chunks.
