While in many cases it's desirable to wait for a buffer to be pushed
downstream when using appsrc-push, in some cases this is not possible as
such pushing action is dependent on following actions that would not be
executed if we wait.
An example for this is prerolling:
appsrc ! qtdemux ! video/x-h264 ! decodebin name=dec ! %(videosink)s
description, seek=false, handles-states=true
appsrc-push, target-element-name=appsrc0, file-name="raw_h264.0.mp4"
set-state, state=playing
appsrc-eos, target-element-name=appsrc0
In order for the preroll to occur, both the appsrc needs to push the
buffer and the state needs to reach PLAYING. But `set-state` cannot
finish if the buffer has not been pushed (the state transition does not
finish) and conversely pushing the buffer will not finish until the
state has reached.
Making appsrc-push not wait for the buffer solves this problem. This
patch makes appsrc-push aware of this issue by only waiting for the
buffer to be pushed if the pipeline is in a state that allows buffers to
flow.
