Random delay and sync for audio for rtsp?

Fri Nov 21 05:06:52 PST 2014

Hi.

I'm playing a live rtsp stream and experience a sort of random delay of the
audio compared to the video. The delay of the audio changes from time to
time between approx. 0.5-2.5 seconds. The GStreamer version is 1.4.4, the
platform is OS X Yosemite and Ubuntu 14.04.1. The stream is generated using
FMLE on OS X and the stream is relayed over a Wowza server to make it
available through RTSP.

The pipeline used to play the stream is this:

    $ gst-launch-1.0 -v uridecodebin uri=rtspt://SOME_PATH/SOMETHING
name=decoder do-timestamp=true ntp-sync=true ! queue ! autovideosink
sync=true decoder. ! queue ! autoaudiosink sync=true

How on earth can the audio be on average 2.2 seconds late and out of sync
with the video?

Output from GStreamer is shown below.

Playing the same stream with VLC, I see the audio is in sync with the video
every time.

Playing the same URL with rtspsrc doesn't seem to work (no video window
appear and audio is silent).

    $ gst-launch-1.0 -v rtspsrc location=rtspt://SOME_PATH/SOMETHING !
decodebin name=decoder ! queue ! autovideosink sync=true decoder. ! queue !
autoaudiosink sync=true

Best regards
Peter
