    Hi,

    I'm grabbing a binary encoded video from a database that I want to play through pyqt5's media player. All of this is in Python:
    The process is:
    encode mp4 to binary using pickle
    store on database
    decode with pickle and store as a variable
    pass that variable to setMedia(QUrl.fromlocalfile(unpickled_video))
    But that's about as far as it gets.

    I've also tried QUrl.fromEncoded() with no luck. I'm really not certain how to pass a video to setMedia that doesn't have an explicit path.
    Is there any known way of passing a binary video file saved in memory to QMediaContent?

    Thanks!
    -Mark

      Hi,

      Not that I remember, however you can create a temporary file where you dump the video and then play it.

      Hope it helps

        That's my last resort. Ideally I'd like to keep any temp files off the hard drive so it doesn't slow everything down.

          Then depending on your OS you could make use of a ramdisk.
