Description Thibault Saunier 2014-07-23 17:09:36 UTC 
You can for example look at:

https://jenkins.arracacha.collabora.co.uk/view/pitivi/job/gst-validate-tests/757/testReport/validate.file.playback/change_state_intensive/mp3_h264_0_mp4/

This can be reproduced doing doing:

gst-validate-1.0  playbin uri=file:///home/thiblahute/gst-validate/gst-qa-assets/medias/mp4/raw_h264.0.mp4 --set-scenario change_state_intensive

This same test works reliably with Gst 1.4 so I think it has been introduced around:

    uridecodebin: Create new sources after chaining up to the parent class
    
    Otherwise we start the new sources already before the parent class
    got ready to start.
