• 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


  



  Results :

  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 ?

  


• Google AppEngine flex as a transcoder [closed]

  6 septembre 2021, par jACK

  Situation :

  


  

  • A Nodejs/Express application running on appengine flex.

  


  • Using FFmpeg to cut videos, and merge different types of videos. 1080p 30fps videos, merged video duration usually around 8 hours.

  


  • Need for a massive amout of processing power for those edits.

  


  • The express server needs to be reachable 24/7 & flex is incredibly expensive if run on a 24/7 basis.

  


  


  Goal :

  


  

  • To have a cost efficient ffmpeg transcoder on a private enviroment =>

  


  • Flex instance as a maximum spec, but as its idle reduce the price significantly.

  


  


  Or is this a situation where a redesign is imminent ? eg. Compute Engine

  


  Tried approach

  


  

  • B8 Standard instance => Since the payload is pretty big, its causing the B8 instance to crash.

  


  


  Thanks.

  


• FFmpeg can't process videos with filenames containing emojis on Google Colab

  I tried searching similar issues as mine here, but most of the solutions are way beyond my knowledge, I'm not sure how to apply them to my use case.

  


  I'll appreciate your help, thank you !
