Anyone find out how to get true 720p or 1080p decrypted?

The problem with this method while it does work, is that for me full quality ends up being 720x480. While with the latest version of netflix which results in the ISMA and ISMV files are very likely full 1080p from the file sizes at 100% quality.

The key method for the ISMV files is below. I can only find very little information about that keyformat but being that HLS streaming and ISMV/ISMA are pretty well known I imagine it has to be possible to decrypt the video in a similar fashion as the AES method. I'm not sure where the key might be stored though if it is on the iOS device at all.

The netflix downloader won't even play these files. It plays netflix 4.0 IPA< perfectly though

KEYFORMAT: com.apple.streamingkeydelivery

The newest media files from netflix support Apple's fairplay DRM system (in addition to playready). The latest Netflix app on IOS 7 supports fairplay decryption. Part of that DRM negotiation occurs within the Netflix app and the final part occurs within the mediaplayer app. The "key" that is retrieved via the .m3u8 is actually an encrypted binary blob which the mediaplayer app uses to fetch the real key from the fairplay subsystem.

In other words, unlike the "crypt0.key", the fairplay mechanism never transfers the fairplay key in plain text.

Until UVD figures out how to get that key, downloading and caching won't work.

OTOH, it is relatively easy to get the (latest) Netflix app to fall back to the old mechanism for DRM (playready). This of course has the disadvantage that SuperHD streams will no longer be available.

Interestingly enough the new format (ismv/isma) does support playready, probably for the "everything else" that uses playready. However the netflix IOS app will only do fairplay DRM on the new format.

I would expect in the near future that netflix IOS app will probably only support fairplay, though. Currently fairplay is only enabled in IOS 7+.

I've attached a tweak for netflix which disables fairplay DRM on the latest Netflix app for IOS. The zip file also contains source code for those curious.

This will disable SuperHD as a consequence. But will allow UVD to work with the latest Netflix app.

scp the deb file to your ios device and dpkg -i to install.

Yes, by disabling fairplay drm and a tweak to add the higher bitrate profiles to the authorization request. Not terribly complicated. If I get time, I'll write the tweak.

Please, I'd really appreciate it! Thanks for that first tweak too!

This tweak disables fairplay on the latest Netflix binary, forcing the player to use playready, allowing UVD to work with Netflix. This tweak also enables HD content allowing 720 and 1080p content to be captured via UVD.

As usual, the source is included for the curious.

To install, scp the deb file to IOS device, ssh in and use 'dpkg -i ...' to install the deb package. Alternatively, put it on a repository and install through cydia.

This supersedes the previous tweak I posted.

Thanks a lot! I managed to download a video which appears to be HD due to file size, but the UVD app won't play the video, only the audio. I went to decrypt the video file like I would usually and when I got my .ts file I can't convert it or watch it anywhere, any idea how I could get the videos to play? Thanks again!
