My pipeline

"webrtcbin name=webrtc bundle-policy=max-bundle latency=0 ! "
	    "rtph264depay ! "
	    "h264parse ! "
	    "video/x-h264,stream-format=(string)byte-stream, alignment=(string)au,parsed=(boolean)true ! "
	    "amcviddec-omxgoogleh264decoder ! "
	    "glsinkbin name=glsink"

Has anyone met similar issues? Thanks in advance for any help.

And eventually it will crash with

I suppose it is amcviddec-omxgoogleh264decoder to blame. I changed the decoder to decodebin3, which uses amcvideodec-omxqcomvideodecoderavc0 under the hood, and no more stalls and crashes now.
