• ffmpeg : Convert a legally purchased video on Google

  24 avril 2020, par Heycava

  I've bought a video on the Google Play Store. I need to have it on my computer in order to edit it for a video montage. But Google says "Important : You cannot download movies and TV shows onto a PC, Mac, and other laptops or computers."

  



  The video has a YouTube link. As I paid for it, I can watch it. I've managed to get the video part and the audio thanks to some web tools.
The video is a .webm file and the audio a .m4a file.

  



  I can hear the audio with VLC but I can't watch the video. Even if VLC displays "21:42" for the timecode.

  



  Here are informations for the webm file (from MediaInfo) :

  It seems to be a good video file.

  



  I wanted to convert it with some video converters but none of them works. So I've tried to download ffmpeg, I renamed the video to "video.webm" and tried a lot of commands. But none of them worked.

  



  Here are informations from ffprobe command :

  



  C:\Users\XXX\Downloads\ffmpeg-20200424-a501947-win64-static\bin>ffprobe -i video.webm

  I've already checked on the Internet solutions for the raised issues :

  



  

  • Invalid frame marker

  


  • unspecified pixel format

  


  • Consider increasing the value for the 'analyzeduration' and 'probesize' options

  


  



  But it didn't work in my case.

  



  Obviously, I can watch the video on YouTube when I'm logged into my purchase account. I presume they have a high level security algorithm, that's why I can't do nothing. Mayve there is something with the "enc_key_id" in the metadata, they get it and the video can only be read with it. I don't know.

  



  I find it unacceptable not to be able to use freely my purchased videos.

  



  Would anyone have an idea ?

  I am using below command to concatenate videos-

  



  String command[] = {"-i",inputFile1AbsolutePath,"-i",inputFile2AbsolutePath .....,"-i",inputFileNAbsolutePath,"-filter_complex","[0:v0] [0:a0] [1:v1] [1:a1]...[N:vN] concat=n=N:v=1:a=1 [v] [a],"-map","[v]","-map","[a]", outputFileAbsolutePath};


  



  and got below error-

  Seeing this answer i tried using-

  



  [0:v]setsar=1[v0]; [0:a0] [1:v]setsar=1[v1]; [1:a1]


  



  but did not worked !

  



  How can i resolve this ?

  I have these information and I want to get same results with ffmpeg. What should I do ? What codes do I have to use ?

  



  Thanks in advance...
