Topic for next meeting: audio/video
Hi everyone Before the last meeting, Ian looked into ffmpeg and was wondering whether it would a good idea for a presentation. I think that widening the topic to general audio/video processing (command line or GUI) would be a rally useful session for people new to Linux (and probably also for more experienced users, finding out about little neat tricks!). Rather than a super in-depth presentation for one application, we can cover a bigger range with a 5-10min show-and-tell per application. I'll assume that Ian will talk about ffmpeg, Lawrence about the other tools that come with ffmpeg, and I will show OBS (Open Broadcaster Software) and Handbrake. Just reply to this thread with your application that you'd like to present.

I can talk about some of the uses I’ve made of FFmpeg. Like this simple wrapper script for grabbing stills <https://github.com/ldo/ffsnap>, or the fun you can have with ffprobe, or filter graphs.
Hi,
I'll assume that Ian will talk about ffmpeg,
My recent observation was that Ubuntu LTS used to supply VLC as the GUI video player in releases 18.04 and earlier. In the recent 20.04 release they have switched to using Celluloid. Celluloid is one of about 20 GUI's available for the command line video application MPV. Of about 50 libraries that MPV depends upon, six are from the FFMPEG set of libraries. $ mpv --list-options displays a total of 883 command line options. The output of $ ffmpeg -h full is about 11,000 lines. Based on the amount of reading involved and commands to learn, the direction I'm heading is to go with MPV and try my best to avoid FFMPEG 😉 So, I'm happy to present MPV, and would prefer to hand-over presenting FFMPEG to someone more knowledgeable on the topic. cheers, Ian.
