I’ve updated the DirectShow MP4 mux and demux filters. You can download the latest source and binaries here.
This update includes:
Support for Motion JPEG in mux and demux (thanks to Steve Sexton) — see further discussion on this here.
Support for CC608 caption data (Line-21 byte pairs). This is not compatible with QuickTime or other players (the data will be ignored). However it is supported by both the multiplexor and demultiplexor.
A fix for incorrect PCM alignment and a fix to the IStream handling (thanks to Maxim Kartavenkov)
