Help with RTP

[Rémi BUISSON]

Hi everyone,

I have some troubles streaming video file over the network.

First of all, I tired this :

server:
gst-launch filesrc location=../partage/Videos/superman_originale.avi !
decodebin ! x264enc ! video/x-h264 ! rtph264pay pt=96 ! udpsink
host=192.168.1.2 port=5000 sync=false

client:
gst-launch udpsrc port=5000 ! rtph264depay  ! decodebin ! xvimagesink

It works but I can't read it with vlc : vlc udp://@:5000 : is it normal ?

Now I would like to do the same thing with an RTP pipeline :

server:
gst-launch filesrc location=../partage/Videos/superman_originale.avi !
decodebin ! x264enc ! rtph264pay ! rtpbin localport=5001
destinations=127.0.0.1:5000

client:
gst-launch udpsrc port=5000 ! rtph264depay ! decodebin ! xvimagesink -->
this works
gst-launch rtpbin localport=5000 ! rtph264depay ! decodebin !
xvimagesink --> this doesn't work

How can I receive my stream ? with vlc ?

Thanks in advance !

Hi and thanks for your reply !

OK I will try today and I will tell you if it works for me.

My goal is to write a streaming server which can transcode, transrate,
... a stream and using a file for clients may be some kind of a
do-it-yourself solution.

For instance, the client send a message to the server for starting the
streaming of a file. Next, imagine the network is overloaded. Then, the
client will ask to the server to decrease the bitrate of the stream.

The client may be VLC, MPlayer, ...

Have you any idea to do it ?

I think it's possible because the streams are standardized.
Moreover, I tried to read a video streamed by flumotion over HTTP and it
works perfectly with VLC.

Thanks again.
