• 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


  


• Why ffmpeg concat results wrong fps ? How to avoid it ?

  29 avril 2024, par Jinglong

  I have several mp4 video files and want to concat there video streams into a new mp4 file. The command I used shows below :

  


  ffmpeg -f concat -safe 0 -i concat.txt -an -c:v copy -y out.mp4


  


  The fps of result does not meet expectations.

  


  For example, there are two input wrote in concat.txt :

  


  file temp_result_0.mp4
file temp_result_1.mp4


  


  




  


  


  


  


  


  


  


  



  


  


  


  


  


  


  


  


  


  


  


  


  


  


  


  


  


  


  


  


  


  file	duration	number of frames	fps	tbr
  temp_result_0.mp4	60.0	1200	20	20
  temp_result_0.mp4	0.1	2	20	20
  out.mp4	60.1	1202	19.97	20

  


  The out.mp4 has correct duration, nb_frames but wrong avg_frame_rate (expecting 20 but get 6010/301).

• Index error with moviepy when running on aws

  29 avril 2024, par Hardik Patel

  I am getting this error :
"MoviePy error : failed to read the duration of file %s.\n"
OSError : MoviePy error : failed to read the duration of file https://delivery.gettyimages.com/downloads/1490392845?k=20&e=AnE-X_nyTRBG5QvUm1OnnCZEOURkdWAdDeQJTmDW8Eo41FL7u_ROCopEha5N-Kwh-fxBr44QIe5s2vzAUchlcVs91TwSlJTMOKWYSTraamKCPRcJv19CqNZRB_FgLaW_.

  


  The funny thing is that for the same line of code :

  


  video_duration = VideoFileClip(getty_url).duration


  


  when running on my mac, it is running fine. However when running from an aws server I am getting this error :

  I checked the version of my package on both mac and aws, the packages are the same. Went through different stackover flow solutions but non of them totally aligns with my issue.
