Description FredT 2015-05-29 22:56:13 UTC 
Pipeline is:

filesink->queue-> videoparse -> queue-> videoconvert -> queue->  decklinkvideosink


When issuing the following command in python

sink.send_event(Gst.Event.new_step(Gst.Format.BUFFERS, 1, 1, True, False))

I can see that the position of the timeline is moving forward for each step but I don't see the video moving forward.

When stepping multiple time the pipeline crash after maybe 10-15 times then I the following error:

I tested the pipeline with frame stepping autovideosink and it was stepping correctly.
