So... I actually got this to work

Postby skydog » 06 Sep 2006 01:35

Here's the setup:
1. Win XP running the latest version of VLC (.85, I think)
2. Axis 210A Camera

Here's what I did:
1. Went to Settings>Preferences
2. Under Stream Output>Sout Stream>Transcode I entered the following:
a. 1, instead of 0 for the audio channels
b. 44100 for the audio sample rate
c. I also selected synchronise on audio track

Now when I transcode the MP4 stream as follows (using File>Open Network Stream, RTSP, and the following for the URL: rtsp://IPAddress/mpeg4/media.amp):
:sout=#transcode{vcodec=mp4v,vb=1024,scale=1,acodec=mp4a,ab=192,channels=2}:duplicate{dst=display,dst=std{access=file,mux=mp4,dst="H:\vlc\teststream1.mp4"}}

Not only can i hear the audio while I transcode, but when I play the saved stream I can hear the audio as well.

After playing around a bit further, I noticed that if I switch the audio channels from 2 to 1, everything stops working. Actually what happens is that the video stream drops after approx. 3 seconds, but the audio stream continues. I have absolutely no idea why this happens, but I did it a few times just to confirm it.

I'm experiencing the same issues with an Axis 241SA Video Server.

MPEG4 stream with G711 audio.
VLC can connect to the rtsp stream and play the video and audio just fine.

VLC can connect to the rtsp stream and record the video but not the audio.

I've tried most of the suggestions in various threads without much luck. Any progress on processing an Axis audio stream through sout?
