mp4decrypt

Decrypt an MP4 file. Part of the Bento4 tools. More information: https://www.bento4.com/documentation/mp4decrypt/.

• Decrypt a file using a specific key (key ID in hex, key in hex):

mp4decrypt --key {{key_id_hex}}:{{key_hex}} {{path/to/input_file.mp4}} {{path/to/output_file.mp4}}

• Decrypt a file using a specific key for a track ID (track ID in decimal, key in hex):

mp4decrypt --key {{track_id}}:{{key_hex}} {{path/to/input_file.mp4}} {{path/to/output_file.mp4}}

• Decrypt a file using multiple keys while displaying the progress of the decryption:

mp4decrypt --key {{key_id_1}}:{{key_1}} --key {{key_id_2}}:{{key_2}} --show-progress {{path/to/input_file.mp4}} {{path/to/output_file.mp4}}
