[Live-devel] stream of audio/video separated files (corrected version)

[Cristaldi Ambra]

Dear Ross,

Thank you for replaying. 

About my last questions a) b), I read this thread http://lists.live555.com/pipermail/live-devel/2006-June/004556.html, and the FAQ (http://www.live555.com/openRTSP/#quicktime , http://www.live555.com/liveMedia/faq.html#m4e-file ). So, my doubts are:

 

1.	I use the test program (openRTSP) of liveMedia, the server is DSS. I use the follow command line: ./openRTSP  rtsp://xxx.xxx.xxx.xxx/sample_100kbit.mp4 <rtsp://xxx.xxx.xxx.xxx/sample_100kbit.mp4>  and I obtain two files: "video-MP4V-ES-1" and "audio-MPEG4-GENERIC-2". If I rename the video one with the ".m4e" extension, I can't open it (I use VLC player). How can I see it in local? And at the same way, how can I open the audio one? I also tried to rename it as "test.aac" and stream it with "testOnDemandRTSP.exe" application, but it doesn't seem to work.
2.	Then, I use the test program (openRTSP) of liveMedia, the server is DSS. I use the follow command line: ./openRTSP -4 rtsp://xxx.xxx.xxx.xxx/sample_100kbit.mp4 <rtsp://xxx.xxx.xxx.xxx/sample_100kbit.mp4>  > test.mp4, but I obtain an empty file. What's wrong?

 

Thank you so much.

Ambra.

	c)    Is it possible to merge the audio and video files to a unique mpeg4 file and play it locally (not stream)?

 

Yes, using the "-4" option to "openRTSP".  Read the "openRTSP" online documentation.

Hi Ross,

 

I've got a couple of questions about stream of .m4e files:

 

a)    I've read all the FAQ and, as described there, I've tried the OpenRTSP to receive an mpeg4 file via RTSP, from a Darwin Streaming Server and record it. As described in the FAQ (http://www.live555.com/liveMedia/faq.html#separate-rtp-streams, http://www.live555.com/liveMedia/faq.html#m4e-file) I obtained two files, an audio one and a video one, but I can't open them. I've tried both with VLC and QuickTime. Can I play them locally? How? Which is the correct extension for the audio files?

 

b)    I try with the "testOnDemandRTSPServer.exe" and "testVideoStreamMPEG4.exe" applications to stream the video file (after renamed it with .m4e extension), I try to see it with VLC, and it works fine. How can I stream the audio too? I try with the other tests but they don't seem to work.

 

c)    Is it possible to merge the audio and video files to a unique mpeg4 file and play it locally (not stream)?

 

d)    I've read in this 3d your opinion about streaming m4e files (http://lists.live555.com/pipermail/live-devel/2007-August/007304.html), but I think this is the only way to stream mpeg4 files, isn't it? I mean: I stream from a device with OpenRTSP, I obtain the two separate files (audio and video) and, if I wish to stream them again, I can do it only using ".m4e" extension. Is it right?

 

 

Thanks in advance, 

Ambra
