Note that ADTS is not quite an elementary AAC stream so if you demux the AAC you might just get a stream of raw data blocks with no headers at all which cannot be decoded unless the decoder knows the sampling frequency and channel config.Date: Wed, 8 Aug 2007 15:52:05 -0700To: [EMAIL PROTECTED]: [EMAIL PROTECTED]: Re: [Live-devel] Couple of questions
Re: [Live-devel] Couple of questions a) So I was looking for something which demultiplexes this TS into audio and video streams. Currently when I look at the code, we do have modules to demultiplex program streams, multiplex into transport stream and also modules to convert from program stream to transport stream. But what I would really need is to either have a demultiplexer for the transport stream, or rather converter from transport to program stream. DO we have either support which I might have missed out? No, our library currently has no support for *demultiplexing* Transport Streams. Sorry. b) Another observation I made is that even if I got the above support to demultiplex into 2 elementary streams( one would be MP4-V-ES ) and other would be AAC supported audio stream(elementary). If my understanding is correct we dont have support for AAC ES right? How hard would it be for me to incorporate this support. Alternatively the SimpleRTPSink might be useful for any type of information, but we have no support for a framer class for the AAC audio type right? AAC audio should be streamed using the "MPEG4GenericRTPSink" class. (See the "ADTSAudioFileServerMediaSubsession" for an example.) Note also that we have a perfectly good RTSP server implementation. You don't need to use a separate 'Darwin Streaming Server'. -- Ross Finlayson Live Networks, Inc. http://www.live555.com/
