    30 septembre 2018, par Arthur Melo

    I’ve been suffering with the vivaldi browser when trying to run some videos, I believe they use codecs that vivaldi can not run using the architecture of my video card, or something of the genre.
    The error does not manifest when using the Safari or Chrome or even Opera browsers.

    i want to stream the audio to "cast" dose this protocol have a more specific name ? its the one that Spotify and YouTube can send audio video to over local network ; little screen with a wifi signal in the bottom left corner.

    


    i am thinking of going into ffmpeg or vlc to stream from usb to some cast program, dose anyone have any suggestions on where to start any key words so im not blindly googling ?
sorry this is so open ended, ill mark it solved with the best answer in like 5 days or when i finish this project ( turntable -> usb audio capture card on pi -> steam to cast protocol -> wifi speakers )
