How to control VLC from Pd Vanilla > 0.46 with native network system?
I want to connect Pure Data to VLC to control it (load files, play, stop, etc).
There is a way to do it by using pyext in https://github.com/mxa/AudioVideoPatches (file 15c-remote-vlc_python.pd), but I think that it is not necessary to use external code to do it (also, I couldn't get it to work). From version 0.48, Pd (Vanilla) has netsend and netreceive to connect to sockets natively.
I'm not familiar with sockets, so I don't know how to do it.
I'm on Ubuntu-Mate x64, Pd 0.46.7, VLC 2.1.6.
Solution
With some help from #dataflow (thanks to undah and dpro) and from pd-list (thanks to Jack), I could make the patch.
- The fix was to send messages with [netsend -b] (as binary).
- I converted some abstracts to subpatchs, to have all in one file.
- It runs on Vanilla, it doesn't need any external.
- If the playlist is long, it isn't shown complete. Same as Help.
Remember to open VLC in this way:
vlc -I rc --rc-host=localhost:1234
And then, open this patch:
