Hello,
Here's a sample file for testing:
https://streams.videolan.org/ffmpeg/incoming/encrypted-hca_lowkey-3201512.usm
Use -hca_lowkey 3201512 for decryption.
One way to test would be the following command:
ffmpeg -hca_lowkey 3201512 -i encrypted-hca_lowkey-3201512.usm -filter_complex \
"[0:a]amerge=inputs=3[a]" -ac 2 -map 0:v -map "[a]" -c:v copy out.mp4
This file has one video stream and three audio streams (one is silence) and
merging the audio streams is reasonable because a game would normally play
every audio stream at the same time. If instead you want to test in some
other way, free free.
Regards,
Pavel Roslyy
