  • Legal issues in shipping apps based on Electron framework (libffmpeg)

    21 juin 2021, par Manmohan Singh

    We're in the process of building and deploying a desktop based app on electron v 12.0.7. It'll be a (free) commercial software deployed to 2-3M users worldwide.
Recently our legal team enquired about the proprietary codecs bundled with chromium and I thought the best way to confirm this would be to reach out here.

    


    So, here're specific things that I need help with :

    


      


    1. Are we shipping chromium with proprietary codecs ? If yes, what are potentially contentious codecs that come by default in chromium bundled with electron v 12.0.7 ?

      


      2. 


    2. Is there any documentation around how the electron team builds chromium (with what flags) ?

      


      3. 


    3. Is the default libffmpeg.dylib/dll bundled with electron building ffmpeg with support for things like H.264 and MP3 codecs ?

      


      4. 


    4. I noticed there are libffmpeg binaries available with each electron build, e.g. https://github.com/electron/electron/releases/download/v12.0.7/ffmpeg-v12.0.7-darwin-arm64.zip . What's the purpose of this binary ?

      


      5. 


    


    Any help would be appreciated.

    avformat/dtsdec : Extend DTS core sync word

    Check extended sync word for 16-bit LE and BE core streams to reduce
    
probability of alias sync detection. Previously sync word extension was
    
checked only for 14-bit streams.
    

    This follows up the similar change in avcodec/dca_parser.

  • FFmpeg - Writing a script to define fontcolor of each word in a text file ?

    1er mars 2019, par distro.obs

    I have a text file with a lot of word separated by newline character like this

    apple
    
banana
    
strawberry

    And I have a list of colors I want those word to appear in

    0xFF0000
    
0xFFFF33
    
0xFF0045

    Also I’m using command like this

    x=:'lte(t,10.99)*0+between(t,11,42.99)*10+between(t,43,643.99)*20+gte(t,644)*30':y='lte(t,10.99)*0+between(t,11,42.99)*10+between(t,43,643.99)*20+gte(t,644)*30'

    to move those words around.

    Is it possible to somehow script ffmpeg to color those words and also move them all in one command ?
