Description jacobhameiri 2013-11-11 07:04:02 UTC 
Perhaps the problem is a race condition between rtspsrc and the pipeline going to PLAYING (or more specific: setting the base time)

Comment 2 Sebastian Dröge (slomo) 2013-11-11 10:35:08 UTC 
Problem here seems that basesink waits for a time that is 26 hours in the future. This seems to be caused by rtpjitterbuffer putting a timestamp on buffers according to base-time 0, while later base-time is set to some large value when the pipeline goes to PLAYING. Or something like that. Later buffers seem to get a correct timestamp by rtpjitterbuffer.

    rtpbuffer: Fix gst_rtp_buffer_ext_timestamp() with clang 5 on iOS/ARM
    
    The bitwise NOT operator is not defined on signed integers.
    Thanks to Wim Taymans for finding the cause.
