pipeline with rtspclientsink does not stop when a rtsp TEARDOWN message is received

Hello,
I have the following pipeline :
autovideosrc ! video/x-raw ! queue ! x264enc key-int-max=30 bitrate=1048 !
video/x-h264,profile=baseline,width=1280,height=720,framerate=30/1 !
rtspclientsink location=server_url user=user user-pw=password protocols=tcp
async-handling=false
I'm running this pipeline in a python script in 2 different ways :
1. Using Tornado's process.Subprocess module
gst_cmd =
"gst-launch-1.0 autovideosrc ! queue ! x264enc key-int-max=30 bitrate=1048
!\
video/x-h264,profile=baseline,width=1280,height=720,framerate=30/1 !\
rtspclientsink user-id=user user-pw=password protocols=tcp
location=server_url async-handling=false"
gst_cmd = shlex.split(gst_cmd)
self.stream_proc = process.Subprocess(gst_cmd)
2. Using the python Gst library
pipeline = '''
autovideosrc ! video/x-raw ! queue ! x264enc key-int-max=30 bitrate=1048 !
video/x-h264,profile=baseline,width=1280,height=720,framerate=30/1 !
rtspclientsink name = rsink
'''
self.video_pipeline = Gst.parse_launch(pipeline)
rsink = self.video_pipeline.get_by_name('rsink')
rsink.set_property('location', gw_url)
rsink.set_property('user-id', 'user')
rsink.set_property('user-pw', source_token)
rsink.set_property('async-handling', False)
rsink.set_property('protocols', 'tcp')
if self.video_pipeline and self.video_pipeline.get_state(0).state ==
Gst.State.NULL:
self.video_pipeline.set_state(Gst.State.PLAYING)
when I set the pipeline state to PLAYING, video is sent to the server and
I'm able to view the streamed video from webcam in both these cases.
However, when the server sends a rtsp TEARDOWN message, the pipeline state
DOES NOT change to NULL in Case-2 (which uses python Gst library). Instead
there is a continuous stream of warnings in the debug logs until I kill the
script manually. Debug logs for both cases are attached at the end.
Any explanation on why there is a difference between using gst-launch-1.0
and Python Gst library would be highly appreciated.
Cheers,
Roshni
