UDP live video playback in UWP

Question

I need to display a live video stream in a UWP application.

The video stream comes from GoPro. It is carried by UDP messages. I think this is a TS MPEG-2 stream.

I can successfully play it using FFPlay with the following command line:

ffplay -fflags nobuffer -f:v mpegts udp://:8554

I would like to play it using MediaPlayerElement without using a third-party library.

According to the following page: https://docs.microsoft.com/en-us/windows/uwp/audio-video-camera/supported-codecs UWP should be able to play it. (I installed the "MPEG 2 video extension" in the Windows storage).

I tried using DatagramSocket and MessageReceived to receive UDP packets, it works without problems:

_datagramSocket = new DatagramSocket();
_datagramSocket.MessageReceived += (s, args) =>
{
    Debug.WriteLine("message received");
};
await _datagramSocket.BindServiceNameAsync(8554);

Then I create an MseStreamSource:

_mseStreamSource = new MseStreamSource();
_mseStreamSource.Opened += (_, __) =>
{
    _mseSourceBuffer = _mseStreamSource.AddSourceBuffer("video/mp2t");
};
this.MediaSource = MediaSource.CreateFromMseStreamSource(_mseStreamSource);

DatagramSocket.MessageReceived MseStreamSource:

using (IInputStream stream = args.GetDataStream())
{
    _mseSourceBuffer.AppendStream(stream);
}

AppendStream HRESULT 0x8070000B . , MediaPlayerElement " ". ( , Windows ).

MseStreamSource ? ?
