I have encountered the following problem
My task is as follows, I need to play streaming video (raw h264 video over UDP protocol) on a 3d object. At the moment I'm using FFmpegInteropX to set a MediaSource to a Windows object.Media.Playback.MediaPlayer.
Media Player works in frame server mode, then I subscribe to the videoFrameAvailable event and transmit the resulting frame to Unity
The problem is that the performance on Hololens2 (UWP) is quite low, I can't get enough smoothness and low latency if I use texture sizes greater than 720x720. At the same time, if I run the application on a PC, I can play everything up to 4096x4096 smoothly and without delay.
Perhaps someone has some ideas on how to improve performance on Hololens2?

UPDATE:
Hello, I did some work.
What I've done:
I have established a direct connection via usb-s - etnernet
I begin to look towards using directx surface
I found the following way to get d3d11 device using by Unity
For this I had to use the library SharpDX, and similar thread https://forum.unity.com/threads/d3d11-texture2d-blitting-framerate.562552
But there are problems that I can't solve yet:
1 FFmpeg works only in the VideoDecoderMode = VideoDecoderMode.Automatic or VideoDecoderMode.ForceFFmpegSoftwareDecoder mode;
2 In the event handler (videoframe_available), there is still a very large load on the Garbage Collector, and apparently this causes performance problems. Moreover, the performance suffers only on Hololens.
In other VideoDecoderMode`s, the stream parameters are determined, but the videoframe_available event never fires. Latency is approx to zero, but perfomance still not very good
Perhaps there are ideas how to solve the problem with GarbageColletor?

The problem was copying from CPU to GPU, the SharpDX library allowed copying frames directly to Idirect3dsurface. I'm attaching the code, maybe it will be useful.

This is the code I am using for QR Scan. It uses XR for Camera input and ZXing to decode the QR Code. I have been at this for 3 days and still have no clue what I am doing wrong. I do not know whether it is that code isn't able to decode the QR, or it can but isn't able to print it out on Output text. Any help would be greatly appreciated. Thank you! :)
These are the libraries I am using :
using System.Collections;
using UnityEngine;
using UnityEngine.XR.ARSubsystems;
using UnityEngine.XR.ARFoundation;
using ZXing;
using TMPro;
This is the code :
IBarcodeReader _reader;

_reader = new BarcodeReader();
_arCam.frameReceived += OnCameraFrameReceived; //When camera receives frame.
}
//Fires off when Frame is received.
void OnCameraFrameReceived(ARCameraFrameEventArgs eventArgs)
{

I imported the DWG file into the eyeshot model. For reading file I used ReadAutodesk class. I want to apply Scaleup and Scaledown on the imported DWG file. I don’t understand how to do that. Can you please help me.
This is code I used.
private void RibbonRadioButton_Click(object sender, RoutedEventArgs e) {
OpenFileDialog openFileDialog1 = new OpenFileDialog() {
Filter = "DWG File|*.dwg|pdf file|*.pdf",
Multiselect = false,
AddExtension = true,
CheckFileExists = true,
CheckPathExists = true
};
string fileName = null;
if (fileName != null || openFileDialog1.ShowDialog().Value) {
System.Windows.Application.Current.Dispatcher.Invoke(DispatcherPriority.Background, new Action(delegate { }));
var rfa = new ReadAutodesk(fileName != null ? fileName : openFileDialog1.FileName);
ScaleTransform aa = new ScaleTransform(2,2.5,1,1);
rfa.DoWork();
rfa.AddToScene(model1);
Entity[] toAdd = model1.Entities.Explode();
model1.RenderTransform = aa;
model1.ZoomFit();
model1.Entities.AddRange(toAdd, NOT_MODIFIED_COLOR);
model1.SetView(viewType.Top);
// Fits the model in the viewport
model1.Invalidate();
}

Using OSMSharp I am having trouble to open a stream for a file (which I can provide on demand)
The error occurs in PBFReader (line 104)
using (var tmp = new LimitedStream(_stream, length))
{
header = _runtimeTypeModel.Deserialize(tmp, null, _blockHeaderType) as BlobHeader;
}
and states: "ProtoBuf.ProtoException: 'Invalid field in source data: 0'" which might mean different things as I have read in this SO question.
The file opens and is visualized with QGis so is not corrupt in my opinion.
Can it be that the contracts do not match? Is OsmSharp/core updated to the latest .proto files for OSM from here (although not sure if this is the real original source for the definition files).
And what might make more sense, can it be that the file I attached is generated for v2 of OSM PBF specification?
In the code at the line of the exception I see the following comment which makes me wonder:
// TODO: remove some of the v1 specific code.
// TODO: this means also to use the built-in capped streams.
// code borrowed from: http://stackoverflow.com/questions/4663298/protobuf-net-deserialize-open-street-maps
// I'm just being lazy and re-using something "close enough" here
// note that v2 has a big-endian option, but Fixed32 assumes little-endian - we
// actually need the other way around (network byte order):
// length = IntLittleEndianToBigEndian((uint)length);
BlobHeader header;
// again, v2 has capped-streams built in, but I'm deliberately
// limiting myself to v1 features
So this makes me wonder if OSM Sharp is (still) up-to-date.

in both of the commented parts i tried doing this, in the first i used while to keep it in the same function but it crashed so i mmoved it into the update function but it still crashes. help?
The while(true)in StartClient() will indeed make the editor / app to be frozen, because StartClient() is not called as a Coroutine, so yield does not return to the Unity engine, and your program is stuck forever in the while.
There is another thing thus. It looks like udp-client.Receive is a synchronous call, meaning it's blocking the code waiting for a packet. The game will indeed freeze unless you have like 60 packets per seconds.

from this i got sample.cs file.now i want to execute that sample.cs file.wil u plz suggest me how to do it?
If it is an application, in a single source file, you can simply do:
