Cool!
My ffmpeg goals are a bit different - multiple cameras filming music performances and linear timecode based audio sync in post production - but I may have some ideas that could help.
Yeah! I found them, after I wrote to this list.First of all, I suggest the FFMPEG mailing list ffmpeg-user@ffmpeg.org.
Oh! Didn't know mpv can be used with plugins - that's indeed one thing I searched for a long time, now: A remote controlled video player! Interesting!My first attempt at KISS for such a requirement would use the UDP protocol for lower latency with Open Sound Control (OSC) with each device as a server that uses mpv playback via its OSC plugin - basically giving mpv remote access to typical transport controls of "play, stop, pause" etc.
Being a server based app over UDP, there really is no latency and the client is totally text based with simple commands.
I'll give it a try. Thank you!
Greets!
