Wow that worked nicely .. but at least for me the video plays fine but I don't hear any audio .. and I know audio is present (checked the .mp4 with Mediainfo)

[WHOOKIDSON]

I sorta fixed that issue .. I edited the decrypt.py and changed the audio instruction in ffmpeg to "libvo_aacenc" instead of "copy"
These are the EDITED lines below

Line 96: subprocess.Popen([ffmpeg, '-i', video_temp_name, '-i', audio_temp_name, '-acodec', 'libvo_aacenc', '-vcodec', 'copy', muxed_temp_name], stdout=subprocess.PIPE, stderr=subprocess.PIPE).communicate()

Line 111: subprocess.Popen([ffmpeg, '-i', output_temp_name, '-acodec', 'libvo_aacenc', '-vcodec', 'copy', '-bsf:a', 'aac_adtstoasc', out_file],

Now I can hear audio and it plays through out fine .. cept for you can tell a little tiny drop or something in the audio

I'm not sure at all but I think while it's decrypting in the temp folder it pieces the audio back together as full .. I believe they are in chunks so that's why it sounds like that when you play the output.mp4

As its decrypting in the temp folder I was watching it and aac files were being produced over and over I assume it was decrypting pieces by pieces then joined them all into 1 AAC then muxed with FFMPEG ..

Transcoding the audio would imply you didn't have codecs installed for whatever it was before. I was able to play the original audio just fine.

Each audio chunk gets mixed with each corresponding video chunk. All mixed pieces are concatenation together and finally converted to .mp4

The audio pieces are not encrypted, also. Just the video.

Also you only need to convert the audio once. I would do it on the second ffmpeg command. That might resolve your audio issues.

mine too doesnt play the audio. but ill mess around with it. by the way the video is in 1080p! how awesome! how did you know what the .key file was?

Thanks! I only edited Line 111 this time and it works .. thank you again

question .. if I DELETE Line 114 .. will it KEEP the temp.ts file?

os.unlink(output_temp_name)


Edit: It worked ..
