[Live-devel] Converting H.264 RTP Video to MPEG-2 Transport Stream

[Ross Finlayson]

> This *should* work, with one modification: You will need to add a 'start code' (i.e., 0x00 0x00 0x00 0x01) before each NAL unit that comes out of the  "H264VideoRTPSource".  You will need to do this - using a separate filter class (that you would write) - before you feed the output into a "MPEG2TransportStreamFromESSource".

You need to implement the (pure) virtual function:
	virtual void doGetNextFrame();

The code has several examples of "FramedFilter" subclass that you could refer to.  (I suggest "uLawAudioFilter.cpp".)
