To decrypt the encrypted mp4 file and store it

Post by mahek » Mon Jun 04, 2018 8:54 am

Hello all,

I am using following ffmpeg command to encrypt the mp4 file having two video tracks with different resolution and one audio track.

ffmpeg -i 10M00S.mp4 -c copy -map 0:0 -map 0:1 -map 0:2 -encryption_scheme cenc-aes-ctr -encryption_key 76a6c65c5ea762046bd749a2e632ccbb -encryption_kid a7e61c373e219033c21091fa607bf3b8 10M00S.mp4_enc.mp4

Now I want to again decrypt the encrypted file. Please help me in decrypting the encrypted file and provide the command for the same as early as possible. Thanks in advance.
