Sorry troller12 I forgot to mention that, but I can provide all the necessary links from this video and the key.
GOD... now I get error "empty playlist"...
Also I am so stupid that I don't know how to to what you said...
will try again...
come back later with results
thank you
LE: here are my m3u8 files which I am so limited and can't modify correctly:
https://ufile.io/68e21
https://sharefa.st/download/kbcmnip1UAF2/rar
I still get empty playlist in ffmpeg...
LE2: all the modified links from the m3u8 file look like this:
no deschttp://cdn.drm.protv.ro/voyo/2017/04/10/159764-d415cfea8fa04e84b60543d1ffaab521.ism/159764-d415cfea8fa04e84b60543d1ffaab521-audio=159985-video=6000000-1.ts
#EXTINF:3
correct?
LE3: So I intentionally NOT modified the URL for the key just to see what is different:
LE4:
So I changed in batch the extension from .mp4 to .ts and now this is happening:
Also I don't really know who ffmpeg works, I would like to extract the original file from the link which I think is .ts?
Also would like to know if I can convert the original .ts file to an .mkv or .mp4 file with the bitrate that I CHOOSE! but this is not a priority, the priority is to modify the m3u8 file correctly.
Ok so the video is 2 hours and 15 minutes and 4 minutes passed and the process is this:

00:00:03.84 meaning 3 minutes from the whole 2 hours and 15 minutes? is there a way to speed this up?
FINAL EDIT:?
Does this means that this is ok? no error message whatsoever. I got it right the first time I edit, what was wrong was the command inside the batch.
I just replaced .mp4 with .ts.
It runs a bit faster now 2 mintes and the progress is at 14 min from 2 hours.
Also will let the other one to finish.
Will come back with results!
