QT6.5 QtMultimedia ffmpeg problems

Question

So i've waited until the full stable release of QT6.5 as instructed by many people from previous posts. I'm still facing the same issues.

playing rtsp video is still not working. MediaPlayer status gives me "invalid media" and errorstring gives me "could not open file"

this code works perfectly on linux. this is a WINDOWS ONLY problem that needs to be fixed.

Running latest qt6.5 release as of 4/3/23. running MSVC2019 with cmake.

import QtQuick
import QtMultimedia

Window {
    width: 1280
    height: 720
    visible: true

    MediaPlayer {
        id: player
        source: Qt.resolvedUrl("rtsp://192.168.2.18/h264_stream")
        audioOutput: AudioOutput {}
        videoOutput: videoOutput
        onErrorOccurred: console.log(errorString)
    }

    VideoOutput {
        id: videoOutput
        anchors.fill: parent
        anchors.margins: 20

    }

    Component.onCompleted: {
        player.play()
    }
}
