@hikohan :-

Absolutely. Ffmpeg is an unbelievably versatile tool, and the combinations of tricks & stuff you can pull off with it can be overwhelming to Joe Average. BUT:-

Ya have to remember one thing, though. The vast majority of Linux users - regardless of their distro of choice - don't want to live in the terminal, and do everything via command-line. Geeks/ubergeeks/neckbeards LOVE the terminal. Joe/Jane Average wants his/her GUIs.....because that's what he/she has always been used to with MyCrudSoft's offerings.

Which is why, even in a featherweight/lightweight 'hobbyist' distro like Puppy, we still tend to prioritise noobs/Windoze 'refugees'.....and try to make stuff as 'user-friendly' as we can. Ffmpeg is phenomenally versatile & powerful, nobody will deny that. User-friendly, however, it very definitely is NOT. However.....

.....if you're happy to do things in that manner, let no man stand in your way! Go for it.

Hi Mike, agree with you!

FFMPEG is versatile in command-line, bash is friendly to geek.

Modify Puppy Linuux your style is great fun!

@hikohan - s15pup64 (& some other pups) have ffconvert in the Multimedia menu (I posted a version in Fossa-Mid thread). This also has an option to screen-capture. Not all settings are straightforward, but I found preset avi works, as do some other presets & other preset/detail combos.
Fossapup64 & Bookwormpup64 have Simple Screen Recorder, which works well. I do appreciate your commandline efforts though.

Not all settings are straightforward, but I found with preset mp4, changing detail to mpeg4 video & aac sound produces decent mp4's.

Well I'm gonna grab this command for my command library!

Would an ffmpeg screen capture work in a tty environment? Sometimes I like to work that way just to prove to myself that I'm capable of it.
