Built LoMux to replace Adobe's Media Encoder
Originally built in python/tkinter and recently oxidized (3mb as opposed to 50mb). I'm sure there's issues in architecture I am missing. It's essentially, at least I think, a pretty damn clean ffmpeg GUI that does everything Adobe's Media Encoder does at a fraction of the hdd space and ram, is portable, and is independent of an expensive suite.

Repo: https://github.com/zblauser/LoMux

Does/Has

• Batch video/audio conversion
• Yt downloading (together with conversion)
• Metadata editor (per file or batched)
• Presets intended to mostly match Adobe's standard options with a few caveats.

Looking to add to the list of possible conversions, as ffmpeg is basically limitless.

It works, ships, I currently use it. I would like some feedback if possible and looking for contributors if you're interested?

Few Questions

1. Architecture - Could this be structured cleaner, afa handling the ffmpeg subprocess and UI communication in rust?

2. Async - In handling long ffmpeg processes, and not freezing, do you think i've got it correct here? It does work, but in terms of optimization.

3. What is the idiomatic for bubbling ffmpeg failures to the UI? It should be known, ffmpeg sends its logging and error messages to stderr, not stdout.

4. Crate choices alright? dependences all solid?

General critique is welcome, not looking to mogged lol, it's my first real rust project.
