NAME
ffmpeg - ffmpeg media converter
SYNOPSIS
ffmpeg [global_options] {[input_file_options] -i input_url} ... {[output_file_options] output_url} ...
DESCRIPTION
ffmpeg is a universal media converter. It can read a wide variety of inputs - including live grabbing/recording devices - filter, and transcode them into a plethora of output formats.
ffmpeg reads from an arbitrary number of input "files" ..

I just found out that #ffmpeg is already recording audio when it starts and there is already a file with the same name so it asks for "Overwrite [y/N]". The video for this part is a frozen frame but the audio is included... How? Why?
At last! Everything's been published about the interactive #videomapping that my great artist and friend @carlosPadial (Asturnazarí) made for the #PenpotFest 2025, with whom I've collaborated closely, 🥳
If all you got is a minute, then watch this reel about how the mapping was experimented in the opening party:

Me: I need to connect to an rtsp stream with 0 buffering or delay…
ffmpeg: Hi!
Me: …and save each frame of the motion jpeg stream as an image…
ffmpeg: -c:v copy -bsf:v mjpeg2jpeg
Me: …but just the one image file that keeps getting overwritten…
ffmpeg: -update 1 picture.jpg
Me: …in a way that means the picture file is always a complete jpeg
ffmpeg: -atomic_writing 1
God I love #ffmpeg, it has every option you could ever want.
Java 25 + Quarkus + FFmpeg + the FFM API.
A full, zero-copy video pipeline in pure Java:
✓ native-speed decoding
✓ real-time object detection
✓ FFmpeg filters (hqdn3d)
✓ MJPEG + WebSocket streaming
✓ no JNI, no subprocess hacks
If you’ve followed my JavaCV + FFM API posts last week, this rounds everything up.

AV1 FSG (stripping film grain and applying it artificially on the decoder) looks interesting, but I wonder if filmmakers really like it.
AV2 is coming soon, but unfortunately I would guess it will take another decade for widespread adoption. The current Apple TV is not even able to decode AV1.

Website for MOC. You're better off working with the version that comes with your Linux distribution or BSD flavor since that one has all the libraries compiled necessary to run.

My motto is; be grateful for all OpenSource software you like to use, give credits to the programmers when you find more useful parameters in your beloved software.
When I play audio files my player of choice has always been MOC; music on console has been stable for decades, is the lightest player I could find and is reminiscent of Midnight Commander / Norton Commander interface.
MOC uses an ncurses interface, has all you need at the fingertips and can play many legacy formats like C64 VIC songs {Last Ninja!} Amiga modules {Das Boot!} with ease.
MOC was released before Video LAN IIRC {I checked}
At a certain point I wanted to play my DVDs in Linux. Logical since my Linux uptime was much, much higher cumulatively, than my win32 uptime, where I gamed. Wine either did not exist yet or could do very little for gaming in general.
Then I learned about libdvdcss thus also about Video LAN.
The fantastic thing about libdvdcss is that you don't have to mess with the region of your player. In that period you had to download libdvdcss yourself from the Video LAN site.
You could only change that region for four times before it becomes permanent at the 5th.
libdvdcss is mighty.
I glanced over VLC, yet didn't brother to download the source code, since I use MPlayer to play my videos in combination with the Mighty FFMPEG library suite. When I finally came around to play with VLC I immediately noticed, how smooth it was coded. I also glanced over the Lua interface, yet left it untouched since I played with MOC, MPlayer / FFMPEG.
VLC X11 UI is handy when you want to move faster than in MPlayer, which made me play more often with VLC when I was in X11.
It was only very recent, that I started to play with VLC in bash.
I was on a notebook which was air gapped so I could not download MOC.
I invoked
`vlc -I
`
What popped up was so beautiful that I was CLI heaven. Every parameter you could think of, where you would normally need to wander with your mouse, you can just type in and get prompted to your shell. You can also do that over the network LAN by the way (wow!)
TIL another powerful feature of VLC cli. If you take the time to add the lyrics of the songs in the album to the directory where the songs reside, VLC will happily show them to you.
I was floored.
This is so efficient.
VLC will not go messing on your internet connection which may be bandwidth metered like mine. VLC cli has so many features you just have to check them out on your own, to see which one you like and then play with them just like I do.
Another impressive feature
One problem we have when we have to downmix 5.1 or 7.1 audio to 2.0 is that the downmix becomes too soft, often 16 decibels too soft. Video LAN fixed that so simple & elegantly.
Video LAN Client is the only one which can push its volume up to 200%!
Thank you Video LAN programmers for this amazing work.

I've been working on an all-in-one file converter program, currently using ffmpeg and imagemagick in the background.
It's still VERY early but I wanted to show it off anyway! The goal is for it to be a super simple alternative to all those "convert X to Y" websites, without needing to mess with complex settings to get results.
P.S. if you're good at ffmpeg or imagemagick, I could really use help. I'm in over my head and they're frustrating to learn.
Fair comment imho
"They are not a vendor, there is no NDA, we have no leverage, your VP has refused to help fund them, and they could kill three major product lines tomorrow with an email. So, stop, and listen to me … ”

Das letzte Stück Weg war das härteste. Nach Wochen diverser Experimente habe ich gestern und heute die letzten Schritte von #unplugtrump abgeschlossen. (Fast) alle Musik aus iTunes raus und in die #Nextcloud (Einige wenige Alben haben einen älteren Kopierschutz von Apple, da muss ich noch ein wenig mit #ffmpeg expirementieren). Genauso wie mehr als 30 Jahre digitale und digitalisierte Fotos.
