Remote API/Calls

mhalbrook

I've been using an app on my Android called unified remote (https://www.unifiedremote.com/).  It has the ability to create custom remotes for Windows, Mac and Linux computers.  One of the things I love with it is that I can create my own custom Widgets with controls from multiple things.  I'd like to build an OpenLP remote with it, but not sure where to find a reference to how to do so.   The Android app is great, but I'd like to create a more customized one that I can add a few other windows buttons to (volume controls, etc).

OpenLP doesn't currently expose a way to control the volume remotely. Also, from an initial poke at UnifiedRemote for VLC, it just focuses the VLC window and presses keys and shortcuts -- hardly any real integration happening there.

I know OPenLP doesn't allow that, but Unified Remote does.  And it can handle more than key presses and short cuts, among the things it can handle are HTTP requests, which I presumed was how OpenLP's remotes communicate with the program.  What I'm hoping to do is create a server in Unifed Remote to work with OpenLP by passing the commands to OpenLP, so I can create a custom remote on my control android that does multiple things.  Right now I have one that works, but only if OpenLP is the active window (using key press sends).  If I could use HTTP requests instead, then it wouldn't have to be the active window.

If you have the web remote enabled you can control all sorts such as:

http://IP:4316

/api/display/desktop;; (desktop/blank/show)

/api/service/previous

/api/service/next

/api/controller/live/previous

/api/controller/live/next

From an old scirpt you can see here how I set a particular page or service item:

set_track() { curl -s --get "http://openlp:password@host:4316/api/service/set" --data 'data={"request":{"id":'$(($1-1))'}}' } set_page() { echo SET $1 curl -s --get "http://openlp:password@host:4316/api/controller/live/set" --data 'data={"request":{"id":'$(($1-1))'}}' }

If you run Node-Red I can paste some NR nodes that we use.

Thanks, for what I need, that will do perfectly.   I've moved on to using Touch Portal, and just did a quick test. works like a charm.

This is a simple control page I created for the free version of Touch Portal.

Is there a way to see what URI calls are in the API? My Next/Previous slide works fine, but the blank to and previous/next items don't work now in the RC.

Thanks, I'll have to look into that and test it with the page and see if it works. If it does maybe I'll push it out. It's kinda nice because I can control system volume and open lp from one tablet page.

Its still early in development, but I'm working on a Python library that knows how to call the OpenLP API, and I'm working on hooking it up with an OSC frontend so that I can control OpenLP with TouchOSC. The library I'm working on could probably be used with WebDings if you prefer to use Midi.

The repo is here on GitHub: https://github.com/rickprice/openlp-OSC-control

Comments welcome, etc.

The Web API of OpenLP so far is quite straightforward to use with Python.
