    I've tested a video streaming from host, I can receive video successfully on RPi, but only in terminal.
    If I launch a Qt app with Media Player it receives but it's broken screen is blinking with only black image, in console I have this strings:
    gst_alsa_device_new: assertion 'caps' failed

    In Media Player I enter only address to video

    MediaPlayer
        {
            id: player
    
            source: "udp://192.168.0.152:10001"
            video Output: video
        }
    

    I've discovered that it's only a problem with Qt. Do I need to reinstall it from the ground up or check for Gstreamer libs, but I've already checked it?

    Qt version - 6.3.2, builded for RPi from sources via cross-compiling

    It's all working normally on x86
