GstBus not getting EOS Event

GstBus not getting EOS Event
 
|
I am new to GStreamer and I have created a small example where I am recording the webcam and used app sink to get the sample but when I try to stop the pipeline by setting its state to null and sending EOS event, my bus callback function never gets called for the EOS. And because of this memory leak is happening. Guys, Please help me import gi import time import threading gi.require_version('Gst', '1.0') gi.require_version('Gtk', '3.0') gi.require_version('GstApp', '1.0') from gi.repository import GObject, Gst, Gtk, GstApp import signal Gst.init(None) class Main: shutdown = False def __init__(self):
signal.signal(signal.SIGINT, self.keyboardInterruptHandler)
self._pipeline = Gst.parse_launch("avfvideosrc
name=avfvideosrc ! x264enc name=x264enc ! appsink
name=appsink max-buffers=1 drop=false sync=false emit-
signals=true wait-on-eos=false")
bus = self._pipeline.get_bus()
bus.add_signal_watch()
bus.connect("message::eos", self._on_eos_from_sink_pipeline)
bus.connect("message", self.on_status_changed)
appsink = self._pipeline.get_by_name('appsink')
appsink.connect('new-sample', self.on_new_sample)
appsink.connect('eos', self.eos)
#bus.connect('message', self.on_status_changed)
self._pipeline.set_state(Gst.State.PLAYING)
def on_new_sample(self, appsink):
return Gst.FlowReturn.OK
def _on_eos_from_sink_pipeline(self, _bus, _message):
print("Got EOS from sink pipeline")
exit()
def eos(self, sink):
print("SINK EOS")
return True
def on_status_changed(self, bus, message):
print('Status: ', message.type)
print('Object: ', message.src)
print('Parsed Message: ', message.parse_state_changed())
def keyboardInterruptHandler(self,signal, frame):
print("KeyboardInterrupt (ID: {}) has been caught. Cleaning
up...".format(signal))
self.shutdown = True
self.stopFetching()
def stopFetching(self):
print("AT THE START OF STOP FETCHING")
self._pipeline.set_state(Gst.State.NULL)
self._pipeline.send_event(Gst.Event.new_eos())
print("AT THE END OF STOP FETCHING")
start = Main()

You cannot expect any messages on the
bus after you have set the pipeline to NULL. Your EOS message
will be dropped on the floor and
`self._pipeline.send_event(Gst.Event.new_eos())` would very likely
return FALSE indicating a failure to send the message.
