From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

what ffmpeg command do I need to cut a portion of a larger mkv file and bind the 2 resulting files into 1? (lemmy.ml)

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

You should be able to pass multiple -ss and -to flags. Should look something like this;

ffmpeg -i "E01 - Part One [x265].mkv" -ss 00:05:50 -to 00:11:00 -c copy 1.mkv -ss 00:58:00 -to 00:68:00 -c copy 2.mkv
ffmpeg -i 1.mkv -i 2.mkv -filter_complex "[0:0][0:1][1:0][1:1]concat=n=2:v=1:a=1[outv][outa]" -map "[outv]" -map "[outa]" output.mkv

I've confirmed that this works fine.
