Modded version of mp4decrypt from:

• https://github.com/NanDesuKa-FR/mp4decrypt_mod_linux
• https://www.bento4.com/

• Changed progressbar
• Removed initial info and output info (Just show progressbar so we can use custom info)
• Removed --show-progress arg (Just show the progress by default)
• Added --silent arg (Don't show any progress)
• Added info to append at the begninning of progressbar

  • e.g. (--key 123:123 enc.mp4 dec.mp4 "[INFO]: ")

    [INFO]: [■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■] 100%

• You can build and modified as well if you want.

mkdir cmakebuild
cd cmakebuild
cmake -DCMAKE_BUILD_TYPE=Release ..

Then build the Visual Studio Project.

usage: mp4decrypt [options] <input> <output> <info>
Options are:
  info: append to the beginning of the progressbar
  --silent : Don't show progress bar
  --key <id>:<k>
      <id> is either a track ID in decimal or a 128-bit KID in hex,
      <k> is a 128-bit key in hex
      (several --key options can be used, one for each track or KID)
      note: for dcf files, use 1 as the track index
      note: for Marlin IPMP/ACGK, use 0 as the track ID
      note: KIDs are only applicable to some encryption methods like MPEG-CENC
  --fragments-info <filename>
      Decrypt the fragments read from <input>, with track info read
      from <filename>.
