• Need help accessing the key when trying to decrypt .ts files via ffmpeg

  4 juillet 2024, par Diz

  I have downloaded all the individual .ts files and the corresponding m3u8 file from a VOD and I now want to merge them together into a single watchable file.
The problem is, that the .ts files are encrypted and don't understand how to access the key.

  


  Here's the beginning of the m3u8 file :

  


  #EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:4
#EXT-X-PLAYLIST-TYPE:EVENT
#EXT-X-MEDIA-SEQUENCE:6484
#EXT-X-KEY:METHOD=AES-128,URI="irvine://aes",KEYFORMATVERSIONS="1",IV=0x1E9ABA2B3C916D47D592D9B1E7674F4B
#EXT-X-PROGRAM-DATE-TIME:2024-05-25T07:24:59.682Z
#EXTINF:4.004,
index_1_6484.ts
#EXT-X-PROGRAM-DATE-TIME:2024-05-25T07:25:03.686Z
#EXTINF:4.004,
index_1_6485.ts
#EXT-X-PROGRAM-DATE-TIME:2024-05-25T07:25:07.690Z
#EXTINF:4.004,
index_1_6486.ts
#EXT-X-PROGRAM-DATE-TIME:2024-05-25T07:25:11.694Z
#EXTINF:4.004,
index_1_6487.ts
...



  


  As far as I understood I only have the initialization vector and I need to access the URI to get the actual key.

  


  I have tried to decrypt the playlist with the following command :

  


  ffmpeg -i index_1.m3u8 -c copy output.ts


  


  But I would always get the following errors :

  


  Unable to open key file irvine://aes
Error when loading first segment 'index_1_6484.ts'
Error opening input: Invalid data found when processing input
Error opening input file index_1.m3u8.
Error opening input files: Invalid data found when processing input


  


  I have also tried just decrypting a single .ts file to start with, with similar results.

  


  ffmpeg -decryption_key 1E9ABA2B3C916D47D592D9B1E7674F4B -i index_1_6484.ts -codec copy index_1_6484_out.ts


  


• Unable find an ffmpeg binary for your Android system

  22 juillet 2024, par Ayush Thakur

  Working on a project where I need to use FFmpeg library in Kotlin to work on some audio files. However I'm unable to initialize the ffmpeg library itself.

  


  this is the error I'm getting

  


  Could not find an ffmpeg binary for your Android system. Did you forget calling: 'new AndroidFFMPEGLocator(this);' ?

        } else {

        }
    }
}


  


  Tried using AndroidFFMPEGLocator(this) ; as suggested by the compiler in my code but unknown reference error is coming for the above line of code.

  


  Also tried using FFmpegKit.init(this) function but init is also not being recognised by the compiler
