playready-rs

Rust port of pyplayready. Currently it does not support creating .prd files and device reprovisioning. Other functionality should be working fine.

As a proof of concept it has been integrated with Kodi. Implementation is available on fork of inputstream.adaptive.

Example usage:

use isahc::{ReadResponseExt, Request, RequestExt};
use playready::{cdm::Cdm, Device, Pssh};

const TEST_PSSH: &str = concat!(

}

It also contains a simple CLI to test your .prd file by connecting to Microsoft's test server.

$ cd crates/playready-cli
$ cargo run test-device /path/to/device.prd
[*] Device: Test Device
[*] Security level: 0000
[*] Certificate validation: true
[*] Content keys:
[*]     xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
