Raw key
|
|
=======
|
|
|
|
*Packager* allows encrypting contents with raw key.
|
|
|
|
Synopsis
|
|
--------
|
|
|
|
::
|
|
|
|
$ packager <stream_descriptor> ... \
|
|
--enable_raw_key_encryption \
|
|
--keys <key_info_string>[,<key_info_string>]... \
|
|
[--pssh <concatenated_PSSHs>] \
|
|
[Other options, e.g. DASH options, HLS options]
|
|
|
|
**key_info_string** is of the form::
|
|
|
|
label=<label>:key_id=<key_id>:key=<key>
|
|
|
|
Custom PSSH(s) can be provided in *--pssh*. If absent,
|
|
`v1 common PSSH box <https://goo.gl/s8RIhr>`_ is generated.
|
|
|
|
Examples
|
|
--------
|
|
|
|
The examples below uses the H264 streams created in :doc:`encoding`. Here are
|
|
examples with DASH. It can be applied to HLS in a similar way.
|
|
|
|
Common PSSH (one key for all streams)::
|
|
|
|
$ packager \
|
|
in=h264_baseline_360p_600.mp4,stream=audio,output=audio.mp4 \
|
|
in=h264_baseline_360p_600.mp4,stream=video,output=h264_360p.mp4 \
|
|
in=h264_main_480p_1000.mp4,stream=video,output=h264_480p.mp4 \
|
|

|
|
in=h264_high_1080p_6000.mp4,stream=video,output=h264_1080p.mp4 \
|

--enable_raw_key_encryption \

--keys label=:key_id=abba271e8bcf552bbd2e86a434a9a5d9:key=69eaa802a6763af979e8d1940fb88392 \
|
|
--mpd_output h264.mpd
|
|
|
|
Common PSSH (different keys for different streams)::
|
|
|
|
$ packager \
|
|
in=h264_baseline_360p_600.mp4,stream=audio,output=audio.mp4,drm_label=AUDIO \
