Add recording controls to client GUI

[magnetic-eagle]

Currently, the only way to record a Jamulus session is for the admin of the server to connect to it via SSH in a headless setup and execute a terminal command, or use the server GUI in a GUI setup. It would be great if clients could start and stop recordings, via a button (and preferably also see the duration of the current recording and an option to play back / download finished recordings) - all this needs a server setting so that it can be disabled if desired. I'm willing to implement the start / stop button, and maybe I'll also work on the other parts later.

I think starting and stopping the server recording bit leaves an additional question: How can the client user get the track files? If that takes a web server, then why not solve the whole problem with a web server? I think I saw an API integration with a web server doing this once, starting and stopping recording and serving up the track files as a zip. dtinth/jamulus-lounge also makes mp3 recording easy.

That sounds interesting - please remember what it was ;)

Agree. The recording happens server side and you may use JSON-RPC + a Webserver to download the files. Also you could record locally with a DAW or similar.

I want to avoid the local recording solution because said DAW needs setting up etc., which is not trivial for all users - if you could point me to any documentation on the JSON-RPC interface (does it allow starting / stopping the recording ?) I could take a look at adding that functionality to jamulus-lounge @mcfnord linked.

I believe such a web UI exists already.

Maybe dtinth or dingodoppelt have something on their profiles.

Here's the API to start and stop recording: https://github.com/jamulussoftware/jamulus/blob/main/docs/JSON-RPC.md#jamulusserverstartrecording

Of course that recording breaks out every track, which one needs for maximum quality, but a lot of people can't mix all those tracks, and many are pleased with an immediate mp3.

I want a JSON-RPC API that makes the red RECORDING banner appear/disappear so jamulus-lounge can control the banner in sync with its mp3 recording activity.

One more thing: There's a build of jamulus-lounge that adds a chat command to record the current jam including a few minutes in the past! I think they call that feature "snippeting".

Yeah I know that about jamulus-lounge, but I want a recording from when i press the button till I press it again :)
