Encrypt both audio and video streams to the same file

[JonasVautherin]

I manage to encrypt the audio and video streams to two different output files with something like:

./packager input=test-video.mp4,stream=video,output=test-video-encrypted.mp4,drm_label=video \
input=test-video-reencoded.mp4,stream=audio,output=test-audio-encrypted.mp4,drm_label=audio \
--enable_raw_key_encryption \
--keys label=video:key_id=20ae55a11663d1a2947be3ede4e2b123:key=5f07cf01b5c31d0f2251f9caad63a5a3:iv=b5096ef9bc43de36e8b57c9344c85a84,label=audio:key_id=20ae55a11663d1a2947be3ede4e2b123:key=5f07cf01b5c31d0f2251f9caad63a5a3:iv=b5096ef9bc43de36e8b57c9344c85a84

But is there a way to encrypt them both to the same output file?

I have tried doing it manually with:

ffmpeg -i test-video-encrypted.mp4 -i test-audio-encrypted.mp4 -c:v copy -c:a copy final_encrypted.mp4

But then both streams are marked as "not encrypted" (though they definitely are) when I run:

./packager input=final_encrypted.mp4 --dump_stream_info

Which suggests that maybe it was not the right way?

  I think the mpd handles audio and video separately
  I really wish if there is an way to handle file with both
