[Live-devel] Which "Source" subclass and "MediaServerSubsession" subclass should be chose for AAC stream?

[ZHOU, Zili (Zili)** CTR **]

Ross,

Thanks for you reply. I still have some questions.
Assume there is an AAC file a.aac exist on RTSP server, and an application continue to append data into the file. Can RTSP server stream from this AAC file at the same time?

Can RTSP server stream from server's *memory* directly?

Thanks for your time.

I want to transfer AAC stream by RTP-over-TCP to live555 RTSP server, is it practical?

Yes, except that you don't stream *to* a server (because that's not what servers should be doing).  Instead, you stream *from* a server.

If your AAC data source already has a RTSP server, then you can either stream from it directly, or - if you wish - use the "LIVE555 Proxy Server" as an intermediary.

If, instead, you want to develop you own RTSP server that streams AAC audio, you can do so by writing your own "FramedSource" subclass that delivers AAC audio frames, and feeding it to a "MPEG4GenericRTPSink".  See, for example, "ADTSAudioFileServerMediaSubsession.cpp", which shows how this is done when streaming from an ADTS-format AAC file.
