I misunderstood, because i thought some videos are unable to be downloaded with popular downloaders like yt-dl and that's why i assumed we need keys to be able to download.
But i'm still confused a bit, if i'm unable to download from the site above (sports.nhk.or.jp) using IDM or yt-dlp, does that mean the video is undownloadable or does that mean wv keys are needed first or anything? -
I write this
and then you ask this
There's no such thing as undownloadable video when it can be played in a browser, wiser men have said.
If yt-dlp gives you 403, it means it needs more parameteres like user agent, referrer and whatnot or maybe another url. -
-
I understand, but how can i find a new mpd link for this video? https://en.sports.nhk.or.jp/olympic/highlights/content/36c93174-8693-4b7b-9412-20b0c253e6c2/

you need VPN japan to play video
then if you open dev tool to search mpd video stops then you need external sniffer to capture http traffic. search on google how to.
when you have found mpd: (now is)
Code:https://vod-d-main-tokyo2020-nhk.akamaized.net/vod/3fcf654c-8c98-4189-ad98-acd8c3ed88c7/36c9317486934b7b941220b0c253e6c2.ism/ZXhwPTE2Mjc4NjYzMTB%2bYWNsPSUyZnZvZCUyZjNmY2Y2NTRjLThjOTgtNDE4OS1hZDk4LWFjZDhjM2VkODhjNyUyZjM2YzkzMTc0ODY5MzRiN2I5NDEyMjBiMGMyNTNlNmMyLmlzbSUyZip%2baG1hYz02NjgyMmQ4M2I0NTdmZTkzZWMxNjgzYzM3YWFiYzFhMDk0OWY0MTEzY2YxMzI4MjQ2YzUwNjYyYzE3Nzc0YWNm/manifest(format=mpd-time-csf,filter=norobo,encryption=cenc)
put on yt-dlp (always with VPN active)
Code:yt-dlp --allow-unplayable-formats https://vod-d-main-tokyo2020-nhk.akamaized.net/vod/3fcf654c-8c98-4189-ad98-acd8c3ed88c7/36c9317486934b7b941220b0c253e6c2.ism/ZXhwPTE2Mjc4NjYzMTB%2bYWNsPSUyZnZvZCUyZjNmY2Y2NTRjLThjOTgtNDE4OS1hZDk4LWFjZDhjM2VkODhjNyUyZjM2YzkzMTc0ODY5MzRiN2I5NDEyMjBiMGMyNTNlNmMyLmlzbSUyZip%2baG1hYz02NjgyMmQ4M2I0NTdmZTkzZWMxNjgzYzM3YWFiYzFhMDk0OWY0MTEzY2YxMzI4MjQ2YzUwNjYyYzE3Nzc0YWNm/manifest(format=mpd-time-csf,filter=norobo,encryption=cenc)

now all video is encrypted. use mp4decrypter to decrypt with:
Code:462ec1033eab4a08b249a33671561a0c:7deb97961102974cbc4b2ac9d4419b84

m4a is audio
mp4 is video
Most of the times you need to decrypt video and audio separately, then merge them with ffmpeg.
But sometimes, audio is not encrypted and you just need to decrypt video.
Use mediainfo to see if the audio is encrypted, or simply try to play with VLC. If it plays fine, you don't need to decrypt it. If it plays weird noise, it is encrypted and needs to be decrypted. -
Yeah, the audio didn't play at all even if i click the play button so i knew it was encryped.
Now i have decryped the audio and the video and muxed them with ffmpeg, this is a nightmare if you want to download and do this for multiple videos.
Do you know if there is a kind of script or anything that can simplify this? -

I am having troubles downloading a video. Here is what I tried:
Video link:
VPN : Japan
Download with yt-dlp:
yt-dlp --allow-unplayable-formats https://dvr-d-main-tokyo2020-nhk.akamaized.net/dvr/2ece2536-eaea-4f85-8854-770dc5f5058...ncryption=cenc)

mp4decrypt --key c6e3832808bd56b63738e89cdd0e35a3:f772989a9f852facd c1268bd548953f7 encrypted_media.m4a decrypted_media.m4a

That's one long ass video.
You probably haven't decrypted them properly.
After decryption of video and audio, before ffmpeg, can you play the actual files?
This is the key I'm getting for that video
ece48b1f2095d34fb47c0798bb29d5f6 (KID=feb029e8546e4225b9eb99dd74e4a0f1) -
yes SoYuKotoDa you have wrong key. to this decryption don't work properly.
and anyway from your key (bad) c6e3832808bd56b63738e89cdd0e35a3:f772989a9f852facd c1268bd548953f7
you have space here ...facd c126... key don't have space -
I think that's a bug on this forum.
It sometimes creates spaces on itself.
Let me try. I'm gonna copy without a space and paste it here, now
c6e3832808bd56b63738e89cdd0e35a3:f772989a9f852facd c1268bd548953f7
see, there's the space.
----------------------------------------------------------------
Now I'm gonna test stuff.
Including the : this string has 65 characters.
If you copy the last 50 characters, no space
63738e89cdd0e35a3:f772989a9f852facdc1268bd548953f7
however, if you copy 1 more character, for a total of 51
b63738e89cdd0e35a3:f772989a9f852facdc1268bd548953f 7
the forum adds a space.

So, yeah, unless it's an URL, I think this forum will add a space if you copy anything more than 50 characters that doesn't have a space.Last edited by [ss]vegeta; 2nd Aug 2021 at 11:50.

No, it doesn't play at all. That probably explains the weird video length.
The real length is supposed to be between 04:53:26
I tried decrypting again with this KID:Key, and it doesn't play either.
Is the issue with the download?
Success !!!
With this key, I've managed to decrypt (decrypted file did not play), and merge audio and video (which plays. Everything is good)Last edited by SoYuKotoDa; 2nd Aug 2021 at 12:45. Reason: UPDATE

Tell me how long did it take for you to download the video? and did you use a VPN?
-
@ Videoer
time to download...depends by your connection
and yes, VPN is needed to download. from japan
@ [ss]vegeta
i think is not a forum bug. for this we need use code tag. if you paste simply, you have space. if you use code tag, don't have any space. try.
@ SoYuKotoDa
i think you use bad command to decrypt your video.
you use this?
Code:mp4decrypt --key <id>:<key> input_video.mp4 ouput_video.mp4
-
@ [ss]vegeta, I think you are right about the space issue.
The space appeared after the copy paste on here.
I was careful about that.
Thanks for the help lomero, vegeta!Last edited by SoYuKotoDa; 2nd Aug 2021 at 14:14.

i repeat: if you use code tag don't have any space. try yourself
from toolbar above message (when write message) on advanced panel you see code tag.
