MPD, license, keys seem fine = videos unplayable [watch.jff.jpf.go.jp]

[casuallyme]

Hi,

would anyone have a suggestion what can be wrong? I get PSSH from MPD, license from getwvkeys.cc... Everything seems to go normally, but files downloaded (yt-dlp or with N_m3u8DL-RE) are unplayable ("wrong codec" -- still encrypted?).

watch.jff.jpf.go.jp

compare kid from the keys (kid:key format) with the kid of the encrypted video/audio (or from the printout of N_m3u8DL-RE).
do they match?

[casuallyme]

I was surprised, but then ignored it. They do differ. How come?

[ElCap]

you must have the wrong keys then.

the kid from the encrypted video/audio file should match the kid from the kid:key format.
that way it knows the correct decryption key for each different encrypted media file.

tl;dr double check the available quality in the web stream and match up KIDs that way (e.g. 1080p video exists, but the decryption keys only go up to 576p)

I'm having the exact same problems. OP will know what I'm talking about probably: I'm going to use Follow the Light as the example in this post (so you can double check your own MPD, etc.) The videos are locked behind a (free?) registration, so I'm not sure what the rules are about those.

I always just used yd-dlp and automatically downloaded the highest quality things (v7+a1 in this case), and inspected the mpd for the PSSH for 1920x1080:

AAAAwnBzc2gAAAAA7e+LqXnWSs6jyCfc1R0h7QAAAKISEEBB3n EFZETvmWK33zdL67USELDXZLr1o0GBk4uVBhMyQ/gSEO3+SiZEzEn6qB7lShK6xaMSEAV0h49L6kl9t7BQQJpUCd8S EOS8N1ISi0I3k1N6sCXipT8SEGhw8o3dDk85qpqjZgfQRvkSEE e3Qmjla0fRqXiNyGN2euASEH+lwOi67k07o6ixeuj99r4iECMH qAMHb0qAnO0Jh/RQlw0=

Then, I entered that into the sites, and got the keys that I just mindlessly copy paste into mp4decrypt. It didn't complain, but none of them worked (output video was the same CRC)

I found this thread and it got me thinking...

I normally use mp4decrypt but was trying shaka to debug, and it complained that it couldn't find a key

[0803/170459:ERROR:decryptor_source.cc(55)] Error retrieving decryption key: 14 (INTERNAL_ERROR): Key for key_id=47B74268E56B47D1A9788DC863767AE0 was not found.

So going back to the original stream and looking at the quality options, the 4 quality options match the KIDs of the outputs of the websites:
360p (0.8Mbit/s) = 640x360 (6870f28d) (v2 in yt-dlp)
432p (1.4Mbit/s) = 768x432 (e4bc3752) (v3 in yt-dlp)
576p (1.9Mbit/s) = 1024x576 (7fa5c0e8) (The bandwidth property says "1791457" inside the Representation tag) (v1 in yt-dlp)
576p (4.0Mbit/s) = 1024x576 (b0d764ba) (The bandwidth property says "4004060" inside the Representation tag) (v4 in yt-dlp)

The 1080p stream is nowhere to be found, so of course shaka couldn't find 47b74268.

I'm learning now!

So it seems we just don't have access to the highest quality streams...I tried it with the 4.0Mbit/s stream and of course it decrypted correctly.

Hope this helps.

...now I gotta go delete all the 1080p streams I blindly downloaded because the keys just don't exist lol

I'm with you all here. Very same experience. From what I can gather, we need FairPlay for HD (720p and 1080p are available with Edge). L3 will only work with SD.

Kudos to some good soul for the key

Hi, sorry to bother, but do you know how to get the keys for 1080p?

[tadanobu]

Nope. As stated before, you need to ask somebody who's able to bypass FairPlay.

[casuallyme]

Where on discord could I look for someone with that skills?

I'm having that problem as well, I used yt-dlp which it downloaded the highest quality available automatically, I spent a lot of my time trying to figure out if there was a possibility to get the key for the 1080p to no avail. I even checked with And Your Bird Can Sing after numerous attempts with an experimental documentary Bachiranun, it's the same problem and this could be applied to the rest of the other movies that I haven't tried with. I did think it's very strange that the keys for 1080p doesn't exist at the moment, despite that the online festival started nearly 2 weeks ago:

They did host another one between March 15 to June 15 this year, I found out about it very late and got the keys for both movies that I was interested in: What Can You Do About It (2019) and In the Distance (2022). I did it at the last minute on June before it reached its deadline. During that final month, 1080p existed so I was able to get them to decrypt the video file. For Bachiranun, I've tried different keys on mp4decrypt and none worked except an existing key corresponding to 576p (3.8Mbit/s). Bear in mind that they have been using Shift72 before.

I imagine that we'd have to wait for some time for the 1080p stream to be available. Still, I don't quite understand why the 1080p option was even there in the first place when it was loading, then it disappeared and showed up with 576p (3.8Mbit/s) at the maximum when I played it. The 1080p does exist in the MPD which you can download separately, it's just the key for it to decrypt is non-existent lmao.

[hikaritenchi]

Yes, this is exactly it. I also got the movies from the last one at the last minute haha.

I always review the available streams and choose them manually instead of relying on the automatic quality choice. This time around, we also had to download the subtitles separately, but they were included in the stream the last time iirc.

If you notice the 1080p streams are available, post here for visibility!

Yeah, for In the Distance, the English sub was hardcoded (same with What Can You Do About It (2019), and there was a Spanish sub that was also hardcoded which could be watched separately. I'm sure the other movies had subtitles that could be downloaded separately during that previous programme.

I have been checking in on the JFF+ consistently, for now, I'm giving it some time and will keep on checking it.

[casuallyme]

Let's hope it will become available...

[jhammer00]

Same problem here, I only 576p stream is able to be decrypted and not the 1080p...

https://online.filmfestival.gr/play/#/film/68704?from=https:%2F%2Fonline.filmfestival....-video%2F&t=80

or

https://online.filmfestival.gr/page/test-your-connection/

it's a free SHIFT72 test video, any suggestions?

[2nHxWW6GkN1l916N3ayz8HQoi]

It wouldn't be the first site that restricts L3 to lower quality

[marktwain]

Hi dear friends i need to download this video from https://en.jff.jpf.go.jp/movie/her_love_boils_bathwater/ It's free, you just need to register.
I get PSSH from MPD, license from dev tools (https://en.jff.jpf.go.jp/dashboard/license/playerkey.js)
But i can't get the decryption key i try from http://108.181.133.95:8080/ or from https://cdrm-project.com/ or other similar portal, even with downey.exe I can't , maybe I'm wrong about the address for the license or I should adapt the headers?
Would anyone have a suggestion what can be wrong? Thanks best regards

Hi, thanks!!! but what method did you use? WVG with custom license scheme?
