debian 12.11

system memory size: 31GiB, 2 15.5 GiB cards

cpu: Intel(R) Core(TM) i7-7500U CPU @ 2.70GHz, version: 6.142.9, size: 3268MHz, capacity: 3500MHz, width: 64 bits

no graphics card whatsoever

computer can play h.265 and equivalent without troubles, provided video file is no higher than 1080 p.

Computer can play av1 files no higher than 1080 p only if I shut every other application down. If for example I run a browser and an av1 file with either mpv or vlc, system shuts down.

Can I put all that memory to use and avoid overloading the cpu?

thank you for pointing that out, corrected.

what happens on my computer: on a terminal, I press ctrl+c but the process keeps working, yt-dlp keeps downloading. As said, the only way to stop it is to shut the tab down (or htop and kill)

 

debian 12.11, yt-dlp stable@2025.07.21

aim: to download the best video available with the largest height but no better than 1080p, excluding av1 as well.

What works:

yt-dlp -f bv*[ext=mp4]+ba[ext=m4a]/b[ext=mp4] -S height:1080 --all-subs

but this command downloads, if possible, av1, which target hardware doesn't support for longer than 5 minutes.

Argument I don't know to add correctly:

[vcodec!*=av01]

I tried:

yt-dlp -f bv*[ext=mp4]+ba[ext=m4a]/b[ext=mp4][vcodec!*=av01] -S height:1080 --all-subs

and other variations, but it didn't work.

second question, aborting an active download not shutting the terminal down: neither ctrl+c nor ctrl+q work and opening htop to kill the process seems overkill. What I now do is to simply shut the active tab, but there must be a faster way.

 

Tinkering with yt-dlp -F

I know av1 is even better than h.265, h.265 being better than h.264

However, I don’t know where to put vpP09, vp9 and avc1

Audio formats: what’s better? m4a or webm?

Thanks. I appreciate.

an approach I wasn't aware of. thanks

Are you positive it’s all the maps or maybe just the world map overview?

yes, I'm sure. It started downloading every.single.country.

look at the fork of OrganicMaps called CoMaps

what's the difference? because graphics and functions look exactly the same for both apps, except the project's icon. Am I missing something?

 

debian 12.11, yt-dlp stable@2025.06.30.

I used this argument: "-f bv*[ext=mp4]+ba[ext=m4a]/b[ext=mp4]"

and it works: it downloads the best available video, audio and ffmpeg merges both in a single file. Automatically.

Except that the maximum resolution I need is 1920 x 1080 p. Best available video is oftentimes 4096 x 2160 p, too much for the target hardware.

Using -F to check different resolutions to then select one (like -f 299 or -f 148) is tiresome.

How do I do that? Ideally for whole playlists involving between 25 and 50 videos.

 

debian 12.11, organic maps from flatpak.

My local organic maps started to download the whole world. Every single map it could find. I tried stopping it but the only way to achieve that is to turn the application off. On starting it again, it resumes downloading.

Why?

The android based version found on f-droid is easier to use. I wanted to use the desktop based one because I work from home more often than elsewhere.

as a noob: on debian or mpv?

 

the x264 av1 file plays only audio on vlc but works with flaws on mpv: on mpv I get audio and video, but every 5 to 6 seconds it's like instead of getting 24 fps I get 22, the user noticing the missing frames.

Is this a hardware issue? software?

debian 12.11, vlc 3.0.21 flatpak, mpv 0.40.0 flatpak

what do I do?

 

when I say trim I don't mean to time trim a file, like getting rid of the last 2 minutes of the mkv file, but to picture trim every frame of the mkv file to get rid of black margins to both left and right of the actual image.

Files were originally recorded on 4:3 aspect ratio (some are movies from the 1950's) but the encoder somehow created / copied huge black margins to both left and right of the actual image. I want to get rid of these.

Some of my files are 30 minutes long but others 2 hours.

if ffmpeg is the application I need, could anyone knowledgeable enough write the actual command?

can it be done for several files automatically?

[–] merompetehla@lemmy.ml 1 points 1 month ago

thank you for taking the time to write the actual command!

 

file title is an option present on mkvtoolnix (92.0 eyeglow on debian 12.11)

I could single open every file, remove the file title and save, but that's gonna take ages. almost 100 files.

 

Debian 12.9

I just downloaded a 30 MiB epub file, but I can discard the images that make most of this space.

Another epub file includes unsolicited advertising with a link to a subscription. I'd like to get rid of it as well.

Is there something I can use?

 

debian 12.9 with ffmpeg.

The mkv file is 68 minutes long, I want to get rid of minutes 05:50 to 11:00 and 58:00 to 68:00. I want the resulting parts (00:00 to 05:00 and 11:00 to 58:00) bind together as a single mkv file.

the ffmpeg command I've always used for similar but easier purposes:

ffmpeg -i "E01 - Part One [x265].mkv" -ss 00:00:00 -to 00:07:28 -c copy output.mkv

can I do this with ffmpeg or do I have to bind the 2 resulting files with mkvtoolnix?

ETA: would it be a better idea to use ffmpeg installed from flatpak instead of debian's default sources? I don't know if ffmpeg is updated regularly

 

I've seen some torrents incorporating both standards in their description and I don't get it. It's either 1200p (1920x1200, WUXGA) or 1080p (1920x1080, Full HD).

What am I missing?

 

the same for vlc under debian

You point your main active network interface gateway to a tor gateway or proxy.

Am I doing that editing the privoxy config file with this line?

'forward-socks5t / 127.0.0.1:9050 .'

I now set up tor for firefox manually using https://www.wikihow.com/Use-Tor-with-Firefox. If the edited privoxy cofig file is the right way to go, didn't I just double torify?

[–] merompetehla@lemmy.ml 2 points 1 year ago (3 children)

how does carburetor work? Do I simply activate it and that means all my traffic goes through tor? just like that? even if I open a terminal and sudo apt update, flatpak or yt-dlp something?

thanks for posting such a detailed answer.

about the different debian versions: I don't know which one I should try first:

I found debian mac 12.5 netinst https://cdimage.debian.org/debian-cd/current/amd64/bt-cd/ and I'm giving it a try.

Shouldn't that work, I'll try one of the live cds https://cdimage.debian.org/debian-cd/current-live/amd64/bt-hybrid/

I paste the links to check if I have the right version

Incidentally, the data size difference is so surprising: 0.66 GB (debian mac netinst) against 3.17 GB (debian live). Can I have something in between?
