Description Tim-Philipp Müller 2012-07-24 17:25:41 UTC 
This does not work well at all for me with playbin:

gst-launch-1.0 playbin uri=rtsp://a2047.v1412b.c1412.g.vq.akamaistream.net/5/2047/1412/1_h264_350/1a1a1ae555c531960166df4dbc3095c327960d7be756b71b49aa1576e344addb3ead1a497aaedf11/8848125_1_350.mov

Basically 2/3 of the picture are completely missing.

A minimal rtspsrc ! depay ! decode ! xvimagesink pipeline works much better though (but still occasionally shows artefacts).

This URL might bring out the issue in a different/n easier to debug way:

rtsp://a2047.v1411b.c1411.g.vq.akamaistream.net/5/2047/1411/1_h264_650/1a1a1ae454c430950065de4cbb2f94c226950c7ae655b61a48a91475e243acda3dac194879adde0f/080690210abcn_2a_650.mov

Get gst_mini_object_unref: assertion `mini_object->refcount > 0' failed and gst_rtp_buffer_map: assertion `GST_IS_BUFFER (buffer)' failed with that.

    xqtdepay: fix buffer refcount error
    
    After pushing the buffer into the adapter, we should not let the baseclass push
    it out anymore. This error was introduced while porting to 0.11.

    avdec: require alignment=au for h264
    
    Because we don't use a parser anymore we need to make sure that we feed the
    decoder with full frames. For h264, require that we are aligned on access
    units.
