Bad RTSP status code with GStreamer

[zoolyka]

Was able to solve it.

Great catch! I'll take a closer look and add this to the repo soon.

[mbullington]

Could you uncomment any log lines and post the entire log up till that point? This may be a feature we don't support right now--not sure yet.

Thanks!

Thank you.

Just found this related topic: https://stackoverflow.com/questions/8699027/extract-audio-from-rtsp-link-for-android

So maybe (in the above case) it should send SETUP and PLAY for simply "/stream" insted of "/stream/stream=0" - if thats the way to request an aggregated stream?

In my understanding appending that control variable to the URL means that you want a specific part (audio/video/etc.) of a stream - which is a non-aggregated call.

The root cause of the problem is now fixed in commit 2028c2a so you should not need the new aggregate flag. However your workaround correctly identified that the problem was Yellowstone mixed up Aggregate URLs and Media Stream URLS.

EG

Aggregate URL = rtsp://1.2.3.4/cats
Video Stream Media URL = rtsp://1.2.3.4/cats/streamID=0 
Audio Stream Media URL = rtsp://1.2.3.4/cats/streamID=1 
Meta data Media URL = rtsp://1.2.3.4/cats/streamID=2

Normally we use Aggregate in DESCRIBE, PLAY, TEARDOWN and the media stream URLs in SETUP
