[gst-devel] GstRtpBin Elemenst Signal "on-timeout"

[Eric Zhang]

Hi, gstreamer-devel:

    1. If the client crash/power failure/network disconnected, there is no
way to send TEARDOWN to server so the server will keep sending packets to
the client. I think there is no way to notify server stopping the streaming.

    2. on-bye-timeout, on-timeout will be emitted by GstRtpBin if bye packet
is received or there is no any packets received for a while. I noticed you
mentioned "TEARDOWN", so I think maybe you're playing a RTSP movie and so
rtspsrc maybe is used in your pipeline. Rtspsrc uses GstRtpBin internally
and connects these signals then do the EOS logics. So I am surprised you
have a GstRtpBin element in your pipeline and wanna connect these signals
manually. Paste your pipeline here, maybe it can make things clear.
