VLC

Post by manaman » Thu Jun 20, 2019 5:15 pm

I have successfully got DP to control VLC running on a Mac (but it could be PC or Linux too, same method). Quite simple, too.

-Enable Telnet control in VLC preferences, choose a port (default is 4212), choose a password, save, then restart VLC. At this point you may want to test the telnet connection from your Mac using Terminal, so the command would be (without the quote marks):
"nc <computer's IP address> 4212" You should then be prompted to enter the VLC password you set. If successful you'll get a message saying 'welcome, master' You can then also use Terminal to test VLC commands (list below).

-Add the computer as a device in DP the usual way with the port and password you set.
-In the 'initial command' bit, enter the password you set in VLC.
-Tick 'disconnect after each command' - to force DP to make a fresh connection for each command.


Here is a list of VLC commands:

Now, I use VLC to throw some RTSP camera streams onto my TV. I have also played with using VLC to play some IPTV streams that have their own individual m3u URLs.

It works pretty well, on a Mac you can completely hide the VLC window and then when you send the command to load a network stream it just appears and goes full screen (if you set the full screen command).

I may spend some time to try and get DP to play content from a NAS based on dynamically generated data, or from a list on a web view, when I have some time. But at the moment I'm quite happy using DP to display RTSP and IPTV on my telly!
