SDK-Samples | repository includes several sample projects | SDK library

Sidenode: I'm not asking anyone to help me with a directx tutorial. I think this error is a normal Visual Studio win32 API error.

Hey guys and girls, I'm trying to learn some DirectX 11 for fun and I found those directx11 examples on github. Now I'm trying to understand each function and see how everything works together. I created a new VS project just to play around with stuff. I copy-pasted all of the code in Tutorial02.cpp into my own project, created a new filter called "Shaders" and changed the properties of my VS solution. At that point I don't have any problems to compile my code. Once I add the Tutorial02.fx, Tutorial02_VS.hlsl and Tutorial02_PS.hlsl to the solution VS can't compile and gives me the following error code:

I am using jitsi-android-sdk in which when I go click home screen it takes me to the picture in picture mode and when I click on the app takes me back to the first form page. How should full screen the picture in picture mode when I click on the app?

what should I put in onResume() so I can full-screen picture in picture on click of the app.

For example, When we are using Netflix and watching a movie on mobile when we press the home button it enters the picture in picture mode and when we click on the app icon it fullscreen the picture in picture mode (return to the movie in fullscreen which we are watching)

I want to implement the same behavior in my android app.

I recently started to learn computer graphics and I need some help.

I'm trying to reproduce a rotation of a "stick" around a circular path in a way that the stick is always tangent to the path. I provided an image to help to illustrate the desired behaviour:

I tried some approaches but never in a successful way. Below a gif with my most recent test, where the small cube represents the circular path that the stick should rotate around but being tangent to the path.

The transformations that I applied to the object world matrices:

I need a consultation regarding developing authentication feature in MS teams Bot. The Bot is meant to be used in MS Teams Channels primarily, and in order to secure the api/messages endpoint, I am using OAuth

Now if the user is not authenticated an OAuthPrompt is created for the user to login and continue participating in the channel's thread conversation, however, the login prompt is sent in the channel thread, which does not provide a good user experience.

Instead, I would like to send the OAuthPrompt to the user as a private message.

How could go about implementing this? I am referring this documentation and this example core-proactiveMessages could someone please help me in figuring this out or pointing to correct resources, examples. Thanks

my goal is to encode the main framebuffer of my Windows machine using nvenc and stream its content to my iPad using the VideoToolbox API

The code I use to encode the h264 stream is basically a copy/paste of https://github.com/NVIDIA/video-sdk-samples/tree/master/nvEncDXGIOutputDuplicationSample the only change is that instead of writing to a file, I do send the data

For the decoding I do use https://github.com/zerdzhong/SwfitH264Demo/blob/master/SwiftH264/ViewController.swift#L71

The encoding work perfectly when I write all the contents to a file, I am able to use a h264->mp4 online converter without issue, the problem is that the decoder gives me the error kVTVideoDecoderBadDataErr in the function decompressionSessionDecodeFrameCallback

So for what I tried:

• Firsly using an h264 analyzer I found that the frame order are: 7/8/5/5/5/5/1...
• I found that nvenc does encode the frames 7/8/5/5/5/5 in only one packet
• I did try to separate this packet into multiple ones using the sequence (0x00 0x00 0x00 0x01), it gave me the frames 7/8/5 separately
• As you can see I only got one 5 frame which is around 100KB, the H264 analyzer said that there are four 5 frames (which are something like 40KB, 20KB, 30KB, 10KB)
• Using a hex file viewer I saw that the sequence separating those 5 frames were (0x00 0x00 0x01) instead, tried to also separate them but I got the exact same VideoToolbox error while decompressing

here is the code I use to separate and send the frames: The protocol is simply PACKET_SIZE->PACKET_DATA The swift code is able to read the NALU types so I am confident that this is not the issue

I'm looking for developing a video conferencing application for Android with the Skype for Business SDK (SfbSDK).

Too see if I'm able to do some needs, I cloned the git repository of the sample application with the SfbSDK dispensed by the Office Developer Team and available here

If the sample application allow me to broadcast the front facing camera and/or the back camera, I don't find any parameters that allow me to modify the camera instance except of changing target camera (front, back ...).

What I want (at least) is to modify the rotation when you turn your phone to landscape mode (modify other parameters would be great too, like Camera.Parameters).

Because if you try it with the sample application, the preview (on the phone) and the outgoing video are both turned like below.

So I've tried to create an instance of android.hardware.Camera and set it to active camera by casting it like this :

videoService.setActiveCamera(com.microsoft.office.sfb.appsdk.Camera)

But It doesn't work ... Or I'm doing it the wrong way ...!

Is this even possible !?

Any suggestion is welcomed.

I integrated amazon pay into my website and i followed the instructions from Amazon Pay SDK Simple Checkout. Its all working so far, but in the last step the code example shows that i need an authorization reference id.

Webjobs version 3 has been out since around September so I want to upgrade from 2.3.0 to the latest version, currently 3.0.4.

The Microsoft.Azure.Webjobs.servicebus package is, however, blocking me from doing so. I tried looking at webjobs sdk samples but they had the exact same issue with the servicebus package blocking the upgrade.

Questions

1. What is the correct way to upgrade the webjobs nuget package?
2. Am I mistaken that version 3 is ready for production yet?

I'm working on a code to capture the desktop using Desktop duplication and encode the same to h264 using Intel hardwareMFT. The encoder only accepts NV12 format as input. I have got a DXGI_FORMAT_B8G8R8A8_UNORM to NV12 converter(https://github.com/NVIDIA/video-sdk-samples/blob/master/nvEncDXGIOutputDuplicationSample/Preproc.cpp) that works fine, and is based on DirectX VideoProcessor.

The problem is that the VideoProcessor on certain intel graphics hardware supports conversions only from DXGI_FORMAT_B8G8R8A8_UNORM to YUY2 but not NV12, I have confirmed the same by enumerating the supported formats through GetVideoProcessorOutputFormats. Though the VideoProcessor Blt succeeded without any errors, and I could see that the frames in the output video are pixelated a bit, I could notice it if I look at it closely.

I guess, the VideoProcessor has simply failed over to the next supported output format (YUY2) and I'm unknowingly feeding it to the encoder that thinks that the input is in NV12 as configured. There is no failure or major corruption of frames due to the fact that there is little difference like byte order and subsampling between NV12 and YUY2. Also, I don't have pixelating problems on hardware that supports NV12 conversion.

So I decided to do the color conversion using pixel shaders which is based on this code(https://github.com/bavulapati/DXGICaptureDXColorSpaceConversionIntelEncode/blob/master/DXGICaptureDXColorSpaceConversionIntelEncode/DuplicationManager.cpp). I'm able make the pixel shaders work, I have also uploaded my code here(https://codeshare.io/5PJjxP) for reference (simplified it as much as possible).

Now, I'm left with two channels, chroma, and luma respectively (ID3D11Texture2D textures). And I'm really confused about efficiently packing the two separate channels into one ID3D11Texture2D texture so that I may feed the same to the encoder. Is there a way to efficiently pack the Y and UV channels into a single ID3D11Texture2D in GPU? I'm really tired of CPU based approaches due to the fact that it's costly, and doesn't offer the best possible frame rates. In fact, I'm reluctant to even copy the textures to CPU. I'm thinking of a way to do it in GPU without any back and forth copies between CPU and GPU.

I have been researching this for quite some time without any progress, any help would be appreciated.
