HI kqyang

I have a one question about DASH encrypted contents,
I am trying to make encrypted dash contents with live profile using normal mp4 file( not from live streaming server).

So, I could made some contents based on READ.ME Document but It looks like they are not perfect.

I inputed like this

.././packager input=normal_audio.mp4,stream=audio,output=encrypted_audio.mp4
input=normal_video.mp4,stream=audio,output=encrypted_video.mp4
--enable_widevine_encryption
--key_server_url "https://license.uat.widevine.com/cenc/getcontentkey/widevine_test"
--content_id "3031323334353637"
--signer "widevine_test"
--aes_signing_key "1ae8ccd0e7985cc0b6203a55855a1034afc252980e970ca90e5202689f947ab9"
--aes_signing_iv "d58ce954203b7c9a9a9d467f59839249"
--crypto_period_duration 140

Result of the conversion is mpd file with segment files, however I observed that first segment file is not encrypted properly. and initialization segment file also,
How Can I encrypt to first segment file and initialization segment file

There are 10 seconds clear lead by default. You could set it to 0 by adding --clear_lead 0 to command line.

The initialization segment will never be encrypted per CENC spec.

Thanks replay quickly,
I was wrong questions , I know that the initialization segment will never be encrypted per CENC spec.

So , What I am saying that, initialization segment file doesn't have any information about pssh data for DRM ,

In spite of I added -- flag ' --clear_lead 0 '
Thanks
Best Regards

With key rotation, the encryption keys may change from this segment to another segment, i.e. pssh for this segment could be different for different segments, so instead of putting pssh in the initialization segment, we put it in the media segments.

Thanks you very much.
