[Live-devel] About AAC Streaming

[Ross Finlayson]

> The issue we have now is that in retransmitting the audio stream we don’t understand if Live555 adds an extra header to the AAC frames.

As I said before - it doesn't.  The frames that come from the "MPEG4GenericRTPSource" are simply AAC frames, with no extra header added.


> We have the jpeg and h.264 pipeline going, we just need to know what headers the MPEG4GenericRTPSource is adding to the aac frames to be able to retransmit it so VLC can play it.

VLC should be able to play the stream, provided that you set up the "MPEG4GenericRTPSink" correctly (as I noted in my previous email), and also provided that you are setting "fPresentationTime" correctly on each outgoing frame.

The best way to test this is *not* to use VLC at first, but instead to use our "testRTSPClient" application.  You should make sure that the "a=config" value in the SDP description is the same as it was in the original ('back-end') stream.
