Gstreamer UDP Source Query

Hi Guys,

I am developing an IP Streaming based media player. I am using the following pipelines:

Src:

gst-launch-1.0 -vvv udpsrc port=5004 ! application/x-rtp, payload=96 ! rtph2 64depay ! h264parse ! imxvpudec ! imxipuvideosink sync=false

Sink:

C:\gstreamer\1.0\x86_64\bin\gst-launch-1.0.exe -v filesrc location=C:\\gstreamer\\1.0\\x86_64\\bin\\hash.h264 ! h264parse ! rtph264pay ! udpsink host=153.77.205.139 port=5004 sync=true

This was the proof of concept. Now, We wanted to have an application which can perform the same operation but with a little tweak when there is no streaming or when no data from the sink, we need to switch to offline base media player, means play a set of videos offline and when there is data on udp port, switch to streaming.

Following are my queries:

Is there any way to find out streaming has been completed after video play over IP
Is there any way to find out there is no streaming happening.

Please help. I am ready to help you if you need more details

Only is you signal this information. An example, the RTSP protocol will
announce the duration, so the other end will know because that duration
have elapsed.

You could use a pad probe that watch for data, and implement a keep
alive stile mechanism.

RE: Gstreamer UDP Source Query

I found the udp src has timeout property which sends an message when there is no data received from the socket. This may help me to say that the stream is completed, but how to find out the start of stream. I am not using RTSP here right, only RTP

RE: Gstreamer UDP Source Query

As Nicolas suggested. Use a pad_probe() on the udpsrc src pad. In its
callback, you should keep track of when you received data for the last time.
You can come up with your own timeout mechanism there but it will also allow
you to detect when data started flowing again after a timeout.
