How to download video from https://www.jff.jpf.go.jp?

[GF983]

I want to download https://www.jff.jpf.go.jp/movie/takano-tofu/, but I don't know the KID:KEY to give to mp4decrypt. Could you tell me how to find it?
This site requires membership registration, but it is free.

What I have done

• I am using Edge on Windows 11.

• I am using https://github.com/vinefeeder/HellYes to get the KID:KEY.

• Executed N_m3u8DL-RE https://www.jff.jpf.go.jp/jff-vod/_definst_/smil:grin:-bIPelz9z8G/Spring-at-Takano-Tof...l/manifest.mpd.
  Downloaded video "1280x720" and audio "p0aa0br96000".
  The following is displayed in the log.
  

  PSSH(WV): EhAi/jV6QYz05sSdRDY2pAEBGgVlemRybUjj3JWbBg==
  KID: 22fe357a418cf4e6c49d443636a40101

• I don't know how to find the license URL. Even after filtering the DevTool-network log with "method:POST", there were no URLs that could be used with HellYes.

Thank you.

your key.

Command to download

N_m3u8DL-RE "https://www.jff.jpf.go.jp/jff-vod/_definst_/smil:D-bIPelz9z8G/Spring-at-Takano-Tofu-Shop.smil/manifest.mpd" --key 22fe357a418cf4e6c49d443636a40101:2ef33c1172e1cfe967c716a210c6475a6 -M format=mkv

[shellcmd]

maybe widevine proxy2 more suit for you.

if you still want to find the license url, you can try to filter lic or cenc or wv

never download from this site, but i remember the license url should similar with fod and hulu jp.

like this:

https://cenc.webstream.ne.jp/drmapi/wv/xxxxxxxxxxxxxxxxxxxxxxxxxxxx

@cedric8528
I was able to get the code working. Thank you!
I was also trying Edge+WidevineProxy2, but when I press the play button, playback does not start and nothing is displayed in WidevineProxy2's Keys.
Edge+WidevineProxy2 works on other sites, so I don't think there is anything wrong with the settings, but do you have any advice?

@shellcmd
I can't find a URL that works with lic or cenc or wv.

[cedric8528]

even if the video doesn't start, try several times...it works with Firefox.

your licence

@cedric8528
Firefox+WidevineProxy2 now displays WidevineProxy2's Keys. Thank you!
Incidentally, when I entered the cURL (POSIX) license you provided into https://github.com/vinefeeder/HellYes, I got an error (Cannot parse an empty license_message).

I tried grabbing this with N_m3u8DL-RE, but the copy protection wasn't removed (green screen).

[pedrothelion]

With Vineless it works...

But has anyone been able to capture the subtitles?

-ss all

doesn't seem to be working

@pedrothelion
You can find the URL of the subtitles on this site by filtering for “vtt” in your browser's DevTool-network.

Thanks, GF983.

[pedrothelion]

Even though I have the key

22fe357a418cf4e6c49d443636a40101:2ef33c1172e1cfe96 7c716a210c6475a6

I can't decrypt the video with mp4decrypt. Does anyone have any suggestions?

tried shaka-packager?

I'm not familiar with Shaka Packager. However, I used the following command:

and the resulting decrypted audio file is corrupted. Is it possible that the key provided by Vineless is wrong?

[iamghost]

Nope keys might only for sd video

[GF983]

Please try the key set in the command written in comment #9.

[pedrothelion]

that's the same one I used... Were you able to decrypt the FHD video?

[pedrothelion]

Nope keys might only for sd video

I understand, but I should have been able to at least decrypt the audio. Instead, even though it has a size of 455 MB, it's corrupted! And mp4decrypt fails completely.

[GF983]

No, it is not the same. There is an extra space in your key.
Also, the key written in #11 contained an extra “1”.

[pedrothelion]

I don't know how that space and the '1' ended up there... But the key doesn't seem to be the right one, even when using the one from post #9.

[GF983]

I just ran the N_m3u8DL-RE command I wrote in #9, and both the video and audio decoded without any problems.

Thanks for confirming. At this point, do you recommend I download the video again?

[pedrothelion]

Yes it works now.

This is curious. It appears Vineless provided the key for the 720p version, while its own command downloaded the 1080p version. The 1080p version is likely L1-protected, which would explain the size difference: the downloaded file was over 10 GB, compared to 1.7 GB for the 720p one.

[GF983]

@pedrothelion
I don't know how to decrypt L1-protection, so I can't help you.
By the way, could you tell me how to download 1080p videos?
I obtained the N_m3u8DL-RE command using Firefox+Vineless v1.3, but it is the same as the command in #9, and when I execute it, only videos with a resolution of 720p or lower appear, as shown below.

Note that the N_m3u8DL-RE command is not displayed in Edge+Vineless v1.3.
