TCP streaming server issue

[Nicolas Hennion]

Hi all,

i currently try to implement a TCP streaming relay server using GStreamer pipeline.

The goal is the following:

- Server listen a the TCP/1234 port for incoming video streaming

- Client 1 send a video streaming to Server

- Server relay the video streaming to a TCP server and listen from incoming request on the TCP/2345 port

- Client 2 connect to the server and receive the video streaming

- Client 3 connect to the server and receive the video streaming

...

Here are the pipelines:

Client 1# gst-launch -tv  videotestsrc ! queue ! videoscale method=1 ! video/x-raw-yuv,width=352,height=288 ! ffmpegcolorspace ! queue ! theoraenc ! oggmux ! tcpclientsink host=192.168.29.65 port=1234 sync=false async=false

Server# gst-launch -tv tcpserversrc host=192.168.29.65 port=1234 ! queue ! tcpserversink host=192.168.29.65 port=2345 sync=false async=false

Client 2# gst-launch -tv tcpclientsrc host=192.168.29.65 port=2345 ! decodebin ! autovideosink

Client 3# gst-launch -tv tcpclientsrc host=192.168.29.65 port=2345 ! decodebin ! autovideosink

I first run the Server pipeline:

===

Définition du pipeline à PAUSED...

Le pipeline a terminé la phase PREROLL...

Passage du pipeline à la phase PLAYING...

New clock: GstSystemClock

===

Then i run the Client 1 pipeline... Unfortunatly, the Server crash with the following error:

===

ERREUR : de l'élément /GstPipeline:pipeline0/GstTCPServerSink:tcpserversink0 : Internal GStreamer error: negotiation problem.  

Please file a bug at http://bugzilla.gnome.org/enter_bug.cgi?product=GStreamer.

Information de débogage supplémentaire :

gstmultifdsink.c(2650): gst_multi_fd_sink_render (): /GstPipeline:pipeline0/GstTCPServerSink:tcpserversink0:

Received first buffer without caps set

Execution ended after 27105365842 ns.

Définition du pipeline à PAUSED...

Définition du pipeline à READY (prêt)...

Définition du pipeline à NULL...

Libération du pipeline...

===

When i replace the Server pipeline with the following:

Server# gst-launch -tv tcpserversrc host=192.168.29.65 port=1234 ! decodebin ! autovideosink

The server receive the video streaming and display the video test on the screen...

Any idea to solve this issue ? I think this is a caps problem but i do to understand where can i set it on my server pipeline ?

Thx in advance for your help

Nicolas
