inf. loop message log

Hello,

I’m constantly getting following error when trying to play RTSP stream, and it looks like as infinite loop, because it prints the same message over and over again:

GStreamer 1.4.5

Pipeline: rtspsrc location=rtsp://184.72.239.149/vod/mp4:BigBuckBunny_175k.mov ! queue ! decodebin ! autovideosink

Full log attached.

I’d really appreciate any help on this one, because it blocks us.

Thanks,

The same stream works with playbin.

It seems that you are linking the 'audio' pad of the rtspsrc to autovideosink. If you replace it with autoaudiosink it should work.

rtspsrc should be creating 2 pads, one for video and other for audio and you need to link them accordingly.

You can check the pipeline used by playbin by running the following command:
GST_DEBUG_DUMP_DOT_DIR=/tmp gst-launch-1.0 playbin uri="rtsp://184.72.239.149/vod/mp4:BigBuckBunny_175k.mov"

and then use 'dot' application to create an image from the files created at your /tmp dir

dot -Tpng < /tmp/myfile.dot > pipeline_picture.png
