seek over TCP

[amitchawla]

Hi,

I am trying to implement seek over a TCP connection between two gstreamer pipelines.

sender pipeline:
filesrc blocksize=4194304 location=C:/Users/Downloads/bbc-japan_1080p.mov ! tcpclientsink blocksize=4194304 async=false host=192.168.100.58 port=3000

receiver pipeline:
tcpserversrc host=192.168.100.58 port=3000 blocksize=4194304 ! decodebin name=demux ! autoaudiosink demux. ! imxeglvivsink

In order to implement a flushing seek across the tcp connection, how would I ensure flushing of the data between tcpclientsink and tcpserversrc ? Do I have to make changes in the tcp plugins?

Regards
Amit

You have to implement an actual protocol on top of TCP that allows you
to signal starts of a segment for example. You can't flush between the
sink and the source, that would require you to instruct all routers on
the way to drop data.

Hi,

Thanks for your reply.

Is this support available with RTSP in gstreamer, particularly for my case, where I need the receiver pipeline (i.e. like tcpserversrc) to wait for a connection and then receive and play the movie stream over that connection.

I will appreciate a reply.

Regards
Amit

That's something that you can implement with gst-rtsp-server, yes.
