how to find m3u8 link (so no need keys)

You can find m3u8 link in the same way that you find the mpd link. (Search the Network panel or use the Stream Detector browser addon)

[ElCap]

yt-dlp -s --print-traffic "url"

Find the m3u8 url and copy it

Or you can add "-N 8" to use 8 threads with yt-dlp (increase it if you want)
Or you can use "--downloader aria2c" to use aria2c to download with yt-dlp
Both will speed up downloading with yt-dlp

oh no jack ...
i know stream detector but he find only mpd, cannot find m3u8 link
and also from all dev tool tab i can't find m3u8 link
but you have tested? you can find m3u8? really strange, i don't think that. i've been tried many time before ask help here

thanks ElCap, i can try your hint
and yes, i know -N option or also aria2c but well i need to understand how to yt-dlp can find m3u8 link

[whs912km]

First, let me thank ElCap for his post.

Allow me to add an addendum (for windows) that will automate the capture process.

yt-dlp -s --print-traffic "url" |  awk " BEGIN{FS=OFS=\"HTTP\"} /m3u8/ { split($1, arr, /GET./); split($2, brr, /\\/); split(brr[3], crr, /:./); print \"https://\"crr[2]arr[2]; }"

[whs912km]

thanks jack but i have an error:

however i don't understand how yt-dlp find m3u8 link .... i can't find it in dev tool anywhere ...

[jack_666]

replace split(brr[3], crr, /:./) with split(brr[3], crr, /\:./)

[whs912km]

jack my final code is that:

yt-dlp -s --print-traffic "https://mediasetinfinity.mediaset.it/movie/i2solitiidioti/i-2-soliti-idioti_F305057501000101" |  awk " BEGIN{FS=OFS=\"HTTP\"} /m3u8/ { split($1, arr, /GET./); split($2, brr, /\\/); split(brr[3], crr, /\:./); print \"https://\"crr[2]arr[2]; }"

but have the same previous error:

[jack_666]

I copied and pasted your code at my end and it worked fine.








Suggest you break the code into small pieces and debug.

[whs912km]

wired
for me work fine yt-dlp -s --print-traffic "url"
but your code give me an error (and it work for you ...!??)

how to solve this? your code help me also for other situation

[ElCap]

jacks code worked for me with awk version 3.1.6 but it doesnt work with awk version 5.0.0.

try this

yt-dlp -s --print-traffic "https://mediasetinfinity.mediaset.it/movie/i2solitiidioti/i-2-soliti-idioti_F305057501000101" | awk " BEGIN{FS=OFS=\"HTTP\"} /\.m3u8/ { split($1, arr, /GET./); split($2, brr, /\\\\/); split(brr[3], crr, /:./); print \"https://\"crr[2]arr[2]; }"

wow ElCap, your last code work great!
thank you so much for your post

and thank you also to jack_666 for the original code

see you guys

[whs912km]

it's possible to change the title of this thread?
i think it's better "how to exctract m3u8 link from yt-dlp" instead "how work yt-dlp" also for future users interested in this topic

if possible, how do i change the title of a thread? i don't find this option ...

[Axel Slingerland]

yt-dlp -s --print-traffic "url"

Or you can add "-N 8" to use 8 threads with yt-dlp (increase it if you want)

Does that depend on how many threads your CPU has? The reason I ask is the specs for my CPU say 6 cores and 6 threads, and I have no idea exactly what that means...

[ElCap]

nah, its just how many fragments to download in parallel.
you can experiment to see what number works best for your system.
afaik, it should just be high enough to max out your (or the servers) connection.

Multi-threaded fragment downloads: Download multiple fragments of m3u8/mpd videos in parallel. Use --concurrent-fragments (-N) option to set the number of threads used

[Axel Slingerland]

Thanks again, ElCap!

[lomero]

i suggest to test with 4 / 6 / 10. no more

or use --external-downloader aria2c as alternative to -N

[Axel Slingerland]

CrymanChen suggested 6 when he explained how to download dash files, and that works so I see no need to mess with it.
