I use FFMPEG as a thermostat to keep my apartment nice and warm :) I encode all of my videos (phone, DSLR, dash cameras) to h265 on my Ryzen workstation when it's not use. I have a primitive "PID-controller" script pulling temperatures from influxdb (data collected using a few esp8266 with ds18b20 sensors) and adjusting -threads parameter accordingly. It automatically adjusts presets (slow, veryslow, placebo, etc) de…

This is amazing. If your alternative is a non-heatpump electric heater, then why not? :)

#223Earlier quoted context omitted.
Well, it's also worth noting that different file extensions can have different associations, so .m4b is more likely to open in an app that the user wants to use for audiobooks, rather than opening in a generic mp4 audio playing app. Even iTunes, I think, would treat files differently between m4r (Ringtone) and m4a (audio) files, so despite there being no difference at all, using the 'correct' extension might be quite…
>Even iTunes, I think, would treat files differently[...] Yes, because it's Apple (of course) who started using non-standard .m4a, .m4b and .m4r extensions, instead of the standard .mp4.
I don’t see a problem with .m4a and .m4v for standalone streams of AAC and AVC respectively.

#224I wish FFmpeg still had NDI support NDI is super useful for low-latency local network streaming

#225Does anyone have a better documentation source for modern ffmpeg? Usually when I use it I get all sorts of different answers with different 'methods', and the official docs only confuse it more. Also I hope to see pure GPU transcoding sometime. H264 to h265 transcodes in pure GPU space are Uber fast, but so far only done by other software.
I’ve pretty much accepted that the project is too big and changing too fast to ever have detailed documentation written.
Apple and Google don’t even fully document their products anymore.

#226I wanted to create a slideshow a couple weeks ago and came across this article [0] on creating a Ken Burns Effect Slideshow. Very cool and is a great demo of some of ffmpeg's functionality. However, the final command is a little crazy: ffmpeg -i 1.jpg -i 2.jpg -i 3.jpg -filter_complex "color=c=black:r=60:size=1280x800:d=10[black];[0:v]format=pix_fmts=yuva420p,crop=w=2*floor(iw/2):h=2*floor(ih/2),zoompan=z='if(eq(on,1…
FFmpeg is infamous for absurdly complex command options. It's really too much for a "one-liner" CLI. When I use it, I just look for "pre-baked recipes" otherwise it's a really unpleasant rabbit hole to get into.
I wrap it in shell scripts or batch files.
