Serviio

Posted: **Sun Mar 25, 2012 11:50 pm**

Hey.

I'm streaming a webcam using Quicktime Broadcaster and a manual unicast to 127.0.0.1. I have exported a .sdp file which I'm hosting on the local web server. I can successfully play this in VLC (via URL http://localhost/screen.sdp). The problem is that Serviio refuses to add it as a Live Stream despite my efforts...

Any tips?

SDP file format is not supported. You'd have to stream it as rtp/rtsp/http streams

Ok, thanks for the heads up. However, how am I suppose to stream it as RTP without the .SDP? That would require some form of automatic unicast right? WIth a proper streaming server and all.

Trying to stream a webcam from my Mac. Any tips on software to use? Maybe FMLE would suffice? That would produce a .flv (or .f4v). Can I stream that with Serviio or do I need to stream to some online server and loop it back? Would be nice to keep this on the LAN.

NOt sure, I'm just basing it on this line

Code:: Input #0, sdp, from 'http://localhost/screen.sdp':

The bit after Input.

Can you open the sdp file in a browser, it seems to be only descriptive format http://en.wikipedia.org/wiki/Session_De ... n_Protocol
It might internally point to a rtsp stream

I sort of cracked the nut. I installed Darwin Streaming Server and set up an automatic unicast from QT Broadcaster. Then I added the rtsp://mycomputer/stream.sdp in Serviio and voilá!

Well, it's not all peachy tbh. Streaming live really stresses my laptop so the stream isn't really stable. Guess I'll have to lower the resolution. I'm just curious over how Apple Airplay streams so nicely to the Apple TV. Any insight?

Closed system... easy.

Yeah. I researched it a bit and it's not really pure streaming, more like mirroring. Would love to find an open source flash streaming server and stream to that.
