[Live-devel] testOnDemandRTSPServer always stream audio/MPA and video/MPV ?

Ross,

Thanks for your answer.

I understand what you say, after sending that mail I start checking the 'stream process' and I found the codecs problems and also why it's using always MPA/MPV.

My question now changes, I need to stream a video+audio file, I  have a .mpg file but I can convert it to any other format with any codec that fit the QuickTimeFileSink object.

You mentioned MPEG4 video and AAC audio, suppose I convert my video to use those codecs, then how can I stream that video+audio file? I ask this because testOnDemandRTSPServer will not help, neither testMPEG4VideoStreamer.

So, is there any way to stream a MPEG4+AAC file with live555? and should openRTSP open that stream and create a .mov file correctly?

I will start reading about add MPEG-1 or 2 support to QuickTimeFileSink.

Thanks in advance,

Jonathan

There's nothing "weird" about this.  The diagnostic output is quite 
clear about what the software is doing (or more precisely, is not 
doing) in this case.

Our "QuickTimeFileSink" code (which implements the writing of ".mov" 
and ".mp4" files) currently doesn't include a mechanism for properly 
storing MPEG-1 or 2 video or audio tracks.  (It supports several 
other codecs - including MPEG-4 and H.264 video, and MPEG-4 (AAC), 
PCM, GSM and QCELP audio - but not (yet) MPEG-1 or 2 video or audio.

You would need to update the "QuickTimeFileSink" code to implement 
MPEG-1 or 2 video and audio.  If you do this, feel free to contribute 
a patch.
