YouTube video time ranged index.m3u8 download doesn't work?

[BlueVideo10]

Let me make an example.

First I need to mention that this doesn't happen on all videos, and I also note that it's with .m3u8

As example: https://www.youtube.com/watch?v=gYjYJmf3_wA


The first thing I'd do is:

yt-dlp -g gYjYJmf3_wA -f bestvideo[ext=mp4]

Then input the link into FFMPEG. And then input time, I put something random that somewhere within the stream for testing.

ffmpeg -ss 50:20 -to 50:25 -i "<PUT LINK HERE>" -c copy out.mp4

And now the issue is that it doesn't work. The -ss parameter and -to should technically as well. But something is wrong with that index.m3u8

So I assume, you want to download only a segment from the original youtube link? In that case you can do

yt-dlp -g gYjYJmf3_wA -f bestvideo[ext=mp4]
streamlink "m3u8_link" best --hls-start-offset 00:50:20 --hls-duration 00:00:05 -o test.ts

You can then mux using mkvtoolnix or whatever else. It's gonna be without sound since you request bestvideo (no audio)

yt-dlp --download-sections "*50:20-50:25" --extractor-args "youtube:player_client=web_safari" gYjYJmf3_wA

ffmpeg -ss 50:20 -to 50:25 -i "<PUT LINK HERE>" -c copy out.mp4

And now the issue is that it doesn't work.

Special characters in file name?
