I have one glorious: ffmpeg -hwaccel cuvid -c:v h264_cuvid -i input.mp4 -vf "hwdownload,format=nv12,scale=(iw*sar)*max(1280/(iw*sar)\,720/ih):ih*max(1280/(iw*sar)\,720/ih), crop=1280:720, subtitles=input.srt:force_style='FontName='TiresiasScreenfont',Fontsize=32,Outline=2,MarginL=50,MarginV=30,Alignment=1',minterpolate=fps=60:mi_mode=blend" -c:v h264_nvenc -preset slow -b:v 8M -f matroska - | vlc - What it does: Allo…
According to Yle they only started using Tiresias in 2012. The article doesn't mention which font they were using before. I would be interested in their 90s font as well. Source: https://yle.fi/aihe/artikkeli/2012/01/27/televisiokanavien-t...
Interesting, I haven't really watched Finnish TV past ten years. However it can't be too different from Tiresias, it was tall as well, and pretty big outline. You can see the 90s font here:

Edit: Comparing 90s font to Tiresias, I would too like to have that exact font they used in 90s. E.g. big "J" is terrible in Tiresias compared to that.

Neither have I. You are right that they are quite similar but not identical.
Ps. Never thought I'd discuss Yle subtitles at Hacker News. Thank you for your comment! :)
Re: FFmpeg 4.4
#124We're all thinking it, but holy cow is FFmpeg one of the craziest pieces of software I have on my computer. The amount of neat things I've been able to do with it and toss them into a bash loop and go to bed is incredible. I'm sure a lot of us get a kick out of automating our tasks, and FFmpeg is king when it comes to that.

I'd add Pandoc to all the ones mentioned in sibling comments.

What you can actually do with these extensions?
I think they let you encode soundtracks and audio effects from the listed games into other formats such as WAV.
They are muxers, which allow you to put already-encoded audio/video (though in the likely case they use standard codecs ffmpeg can also handle the encoding for you) into these file formats.

#126FFMPEG is truly the best thing so far, always wish I could contribute directly but I'll stick to working on the Python wrappers.
ffmpeg-python is used at my workplace so if you've ever cleaned up the docs, or submitted a patch, you have my greatest thanks! Saved my ass big time a couple weeks ago.

GraphicsMagick is like ImageMagick but much more sane & performant.

Looking at the comments in that ticket, I can understand why ffmpeg developers don't want to help those people, and the devs probably spoiled more time answering this annoying person than it would take to have fixed the issue, making them lose all motivation to work on that issue.
wow, this is crazy. I would never have imagined this level of a shitshow when you said "annoying"... But what to do with such a person if you can't/won't ban them from posting? Delete his comments? Don't engage until he tires himself out?
This person isn't doing anything wrong. He's appealing to what he perceives as universal principles to attract attention to a technical matter of importance to him. Yes, he's being aggressive; no, there's nothing wrong with that.
If you take away the voices of such people, pretty much the only voice left speaking is the voice of corporate money, which is usually anthithetical to the principles of open source development.
EDIT: Especially considering features like Gopher and MSP were deemed worthy of attention, the fact that his point about HDR metadata being silently stripped was not being addressed in a year is concerning.

Being an asshole is bad, specially when you are asking for help. Not being an asshole doesn't make you a corporate shill nor being an asshole make your feedback "better".

#130I think everyone was a txt file on their computer filled with FFmpeg commands. Care to share yours?

> Extract audio from a video
If you use `-vn` and `-acodec copy` (I use both although not sure `-vn` is strictly necessary), you can demux the audio from the video in the same format it is already in. Of course, you're extracting to wav so not transcoding, but copying may be faster/use less space.
