RTSP streaming issue

sebbesen
Hi,

I'm new to gstreamer so bear with me please. I'm having issues playing back an audio stream over rtsp on a Raspberry Pi 3 (Jessie). My best attempt was:

gst-launch-1.0 rtspsrc location=rtsp://<my-rtsp>.stream ! decodebin ! alsasink --gst-debug-level=3

The most interesting line form the debug information is probably:

decodebin gstdecodebin2.c:1813:analyze_new_pad:<decodebin0> error: A MPA audio RTP depayloader plugin is required to play this stream, but not installed.

I believe I have pretty much all possible plug-ins installed (good, bad, ugly...). I tried adding all kinds of other stuff to the pipeline such as rtpmpadepay, but it didn't help. I realized that omxplayer can easily play the stream which I used to collect a bit more information. The output of omxplayer -i rtsp:/<my-rtsp>.stream is

Stream #0:0: Audio: mp3, 44100 Hz, mono, s16p, 64 kb/s

Your help is very much appreciated!

Kind regards,
Soren

For starters, it might be worth trying

  gst-play-1.0 rtsp://<your-rtsp>.stream

or

  gst-launch-1.0 playbin uri=rtsp://...

Hrm, so yo have rtpmpadepay installed, but it still complains about the
above? That's unexpected. If you can make the stream public or upload a
debug log somewhere that'd be helpful, then we can take a look.

Also, have you tried the same pipeline with GStreamer on a recent
desktop/laptop distro to see if it happens there too?

Cheers
