SDP file with VLC

[de_ninja]

Hello,

I hope i can find some help here.

I want to stream from my raspberry to my windows computer.
I have a working pipeline:

gst-launch-1.0 alsasrc device=plughw:Device ! mulawenc ! rtppcmupay ! udpsink host=127.0.0.1 port=5000

I can receive the stream on my windows computer with gstreamer. I need the stream to be played with vlc so I tried to make a sdp file. When I open it on my Windows computer (client) nothing happens. Am I doing something wrong? I'm pretty new to this so thanks for helping!

my SDP file:
v=0
m=audio 5000 RTP/AVP 0
c=IN IP4 127.0.0.1
a=rtpmap:0 PCMU/8000

127.0.0.1 is localhost you need to put the proper IP address in your sdp file

Thank you very much for your help!
 One more question:
I am using a raspberry pi as a host. is there a way to deposit the sdp file there and to receive it by opening a network stream on the client with rtp://@<ip>:<port>/stream.sdp?

[Thornton, Keith]

Rtp doesn't specify how the sdp file is distributed. There are various ways to achieve this such as having a mini web server and getting it with http get.

Or just use RTSP (e.g. gst-rtsp-server), which is basically (as used
most often) like HTTP to get an SDP for RTP streams.

Thanks for the answers.
I uploaded an sdp file to my homepage, it worked.
My goal was to receive the streams on mobile devices. This worked too, I could open the file on my webpage with the vlc app for Android. Unfortunately the quality is kinda bad and the latency is about 2 seconds (same pipeline with gstreamer on windows has about 0.1-0.2 seconds).
Is there any way to get decent quality and near real time audio on my mobile devices with apps that already exist?
I want to connect my raspberry pi to a tv in my fitness centre, which doesn't have speakers, so multiple people can listen to the tv's audio with an app in real time.

Maybe another codec/payload could help?
I also get horrible dropouts when using an .255 ip for broadcasting
