I've managed to encrypt my video files using the ffmpeg command below however I can't find a way to save the decrypted output.
ffmpeg -i {file} -encryption_scheme cenc-aes-ctr -encryption_key {key} -encryption_kid {checksum} e.mp4
This post has an example for playing the video back using ffplay which works but I want to save the outout to a file and want it done faster than normal playback speed.
Tryed using decryption_key also but get "Error while decoding stream #0:0: Invalid data found when processing input"
ffmpeg -i {file} -max_muxing_queue_size 9999 -decryption_key {key} d.mp4
