On state change from PLAYING to NULL hangs

Hi,

Gstreamer state change API used for video pipeline as below:

gst_element_set_state(pipeline, GST_STATE_NULL); // code hangs on this line

Especially wayland sink does not go to null state.

Details: kernel 4.4.14

Processor SDK:3.00.00

Pipeline: appsrc ! h264parse ! ducatih264decvpe ! queue name=myqueue max-size-buffers=2 ! waylandsink sync=false

Hi,

Can you provide more debug information? The change state to NULL is present in gsttestplayer as well. I haven't observed any hang issue.

Thanks and Regards,

hi pooja,

We played one mp4 file using gsttestplayer.
On typing exit command video player command prompt still available.
Also on reaching last frame, on screen the last frame would be rendering.
Ideally EndOfStream event should have be given.

Hi,
I replicated the steps you mentioned on both kmssink and waylandsink. I do not have the same observation as you. Ideally you should be calling stop to stop the playback. Even when I type exit without stop, it works fine for me.
