Cannot download encrypted m3u8 video, the video works on the website

[krestek]

Hello! We have really weak internet here, so I'm trying to download the videos instead of watching directly on the website (tried waiting for it to buffer, but sometimes it disconnected and restarts on its own), so my only option is to download them somewhere with good internet and watch them on my own terms at home. (yes university would not even help us)

Here's the m3u8 http://5b237d5dc89e5.streamlock.net/protect/_definst_/smil:SuatGurcanCikmisSoru/2013yd.../playlist.m3u8 of playlist and this one http://5b237d5dc89e5.streamlock.net/protect/_definst_/smil:SuatGurcanCikmisSoru/2013yd...6000_slTR.m3u8 for 1080p stream.

With youtube-dl I'm getting "Error when loading first segment" after it downloads the first ts file. yt-dlp downloads the whole file but it does not open with vlc or anything else basically, I'm assuming it's still encrypted, the key changes between sessions as far as I understand so I'm wondering why yt-dlp didn't decrypt while downloading? Also why ffmpeg gives that error? Is the TS file still encryped when presented to it?

Also the links for m3u8 playlist etc and keys aren't protected, they can be anonymously requested just fine, so not sure why it doesn't work.

Thanks!

There is no URL data in the m3u8 file, you are not actually downloading any audio files with your method and that is why it won't play...

Incorrect.

@OP download the file the key url gets you, open with hex editor, copy hex (that's your key), use it with hlsdl 0.27 to download
hlsdl -k "key" "m3u8 link"

I haven't really investigated why these more popular tools fail to download. But this isn't their first time

My suspicion is error tolerance.

yt-dlp and youtube-dl fail due to Invalid data found when processing input

My suspicion is that hsldl just accepts it and moves on
