Streaming the Linux desktop to Kodi using VLC and RTSP
+
12th July 2018
+

A while back, I was asked by a friend how to stream the desktop to +my projector connected to Kodi. I sadly had to admit that I had no +idea, as it was a task I never had tried. Since then, I have been +looking for a way to do so, preferable without much extra software to +install on either side. Today I found a way that seem to kind of +work. Not great, but it si a start.

+ +

I had a look at several approaches, for example +using uPnP +DLNA as described in 2011, but it required a uPnP server, fuse and +local storage enough to store the stream locally. This is not going +to work well for me, lacking enough free space, and it would +impossible for my friend to get working.

+ +

Next, it occurred to me that perhaps I could use VLC to create a +video stream that Kodi could play. Preferably using +broadcast/multicast, to avoid having to change any setup on the Kodi +side when starting such stream. Unfortunately, the only recipe I +could find using multicast used the rtp protocol, and this protocol +seem to not be supported by Kodi.

+ +

On the other hand, the rtsp protocol is working! Unfortunately I +have to specify the IP address of the streaming machine in both the +sending command and the file on the Kodi server. But it is showing my +desktop, and thus allow us to have a shared look on the big screen at +the programs I work on.

+ +

I did not spend much time investigating codeces. I combined the +rtp and rtsp recipes from +the +VLC Streaming HowTo/Command Line Examples, and was able to get +this working on the desktop/streaming end. Note the 192.168.0.4 IP +address is my desktops IP address:

+ +
+vlc screen:// --sout '#transcode{vcodec=mp4v,acodec=mpga,vb=800,ab=128}:rtp{dst=projector.local,port=1234,sdp=rtsp://192.168.0.4:8080/test.sdp}'
+
+ +

I ssh-ed into my Kodi box and created a file like this with the +same IP address:

+ +
+echo rtsp://192.168.0.4:8080/test.sdp > /storage/videos/screenstream.m3u
+
+ +

Next, first locate the file in Kodi and select the m3u file while +the VLC stream is running. The desktop then show up in my big +screen. :)

+ +

When using the same technique to stream a video file with audio, +the audio quality is really bad. No idea if the problem is package +loss or bad parameters for the transcode. I do not know VLC nor Kodi +enough to tell.

+ +
