Hi,
I have a frustrating situation where I can't stop gstreamer main loop with
gst_element_send_event(gstPipeline, gst_event_new_eos()) called from user
thread.
This is the pipeline string I'm using for gst_parse_launch:
"udpsrc port=43444 ! video/mpegts ! tsdemux !
video/x-h264,stream-format=byte-stream,alignment=nal ! appsink
name=appsinkname sync=false drop=true max-buffers=1
enable-last-sample=false"
below is the GST_DEBUG output:

Somehow pipeline items are going from PLAYING state to PAUSED state, and
then they go PLAYING again as seen above.
An important information is that pipeline do not stop if I don't send any
video data to above port, but it stops perfectly if any video data is sent
to the port.
Note that, gst version is 1.16.0.
Can someone please help?
Thanks,
