Description Rafal 2017-09-10 18:42:56 UTC 
When playbin element is used with video-sink property set to v4l2sink, the pipeline stops to play after a few changes between paused and playing. Further switches between paused and playing state have no effect.

It looks the problem is caused by the v4l2sink element, more precisely by gst_v4l2_object_unlock function invoked by gst_v4l2sink_unlock. The gst_v4l2_object_unlock function invokes gst_buffer_pool_set_flushing, which sets the pool in flushing state. This infers the pool use by other threads and under certain circumstances may switch whole pipeline into flushing state.

When I did remove in code the gst_buffer_pool_set_flushing function call in gst_v4l2_object_unlock function, the problem stopped to appear.

Let me know if you need more information. Thank you.
