Ffmpeg widevine cenc decryption with multiple keys

[matthias1232]

Hi together,

i applied a patch for ffmpeg which makes it possible to decrypt mpd dash streams with multiple keys.
It‘s the option -cenc_decryption_keys


https://patchwork.ffmpeg.org/project/ffmpeg/patch/20231113084019.5081-1-adrien@guinet.me/

https://github.com/matthias1232/FFmpeg

The compilation and build worked with Ubuntu 22.04

I got the command running and decryption works with a singe key.

/usr/local/bin/ffmpeg -f dash -cenc_decryption_keys b9931924531e5d22967a749ab110xxxx=5763de9f8d969yxxx ca57f6527f5e6e41


But i dont know how i should write the command to apply more than one key.

> This commit introduces new options to support more than one decryption
> keys:
> * add a decryption_keys option to MOV, that supports a dictionnary of
> KID=>key (in hex), using AV_OPT_TYPE_DICT
> * add the corresponding cenc_decryption_keys option to DASH

I tried it seperated with a „,“ and also to applied the -cenc_decryption_keys command multiple times but i didnt work in any way.

Can someone please explain me how the command should look like?

Thank you guys

Off topic but did you try asking in ffmpeg dev IRC ffmpeg https://www.ffmpeg.org/contact.html#IRCChannels

[LZAA]

-cenc_decryption_keys key1:key2 or
-cenc_decryption_keys key1;key2

Wow amazing @LZAA, this worked.

I just have an problem with playback. The Stream initial Load takes about 15 Seconds to start and interrupts after about 5-10 Seconds of Streaming
