[Live-devel] openRTSP Command Line Tool

[Maik Brauer]

Hi there,

I've tried now several times to save a Stream with openRTSP to play it
afterwards with (VLC, or other Player-Applications)
The stream which is arriving is a H.264 Stream with AMR Audio Codec.
After a while (2 Minutes) of recording and writing it into a file I've
stopped it and have tried to open it via a player like mentions above.

But what I can see is only a picture. It is not possible to hear the
audio-layer.
I've tried to record it in separate files, which means a file for:
video-H264-1 and Audio file: audio-AMR-2
This is as well not working. Is there any problem in the openRTSP
tool, maybe a known bug, or did I make something wrong?

If you need some samples, please let me know, so that I can send you
some traces or details.
Many Thanks in advance.


Cheers,
Maik Brauer

I think the problem here is only that VLC (at least, by default) does
not include an AMR audio decoder, and therefore cannot play the audio
from your stream.

If you rename the audio file to have a ".amr" filename suffix, then
you should be able to play it in QuickTime Player (which has an AMR
decoder).

Hi,

I've compiled the AMR audio codes into the VLC Software.
I'm able to play video and audio when I'm connection directly to the
streaming source,
for example a Darwin Streaming Server.
But if I try it via openRTSP, where I'm opening a saved file it is not
possible,
So something must be wrong with the saved files.

Renaming in AMR (suffix) is not working as well.
The suffix is at least not that interesting if you force an
application to open it.
It is only a cosmetical an Plug and play feature, twith this suffixes.

So what can I do else?
Any suggestions??


Cheers,
Maik

Not necessarily. Are you able to play the file in QuickTime Player
(after you change the name to have the ".amr" filename suffix)? If
so, but you're not able to play the file in VLC, then the problem is
that VLC is not properly interpreting the content of ".amr" files.

With the Quicktime it is not working as well.
You will get a Error -2002: a bad public movie atom was found in the
movie.

I tried to stream again with openRTSP and I have saved the stream again.
After opening it with Quicktime I'll get the same error.

If you are using directly the VLC or Quicktime together with the
Streaming Server it is working.
So the Saved stream is not OK then.

What else can I do ?
Is that a common behavior of openRTSP.

Cheers,
Maik

That's odd. Are you sure you're renaming the file so that it has a
".amr" filename suffix (*not* ".mov" or ".mp4")?

Playing received AMR files with QuickTime Player (after renaming them
to have a ".amr" suffix) should work. I've done it several times.
