decoders | Protocol decoders for the SmartScope | Messaging library

I have a Stryker test with this stryker-config.json:

I'm running into issues opening a jpg file. Here is the code I started with:

Say I have parent class A: Codable with subclasses B1: A and B2: A. A different class Main: Codable in my application has a pointer to an A which can either be a B1 or a B2 but cannot be an A (I'm effectively treating A as an abstract class).

When I am decoding a Main, I run into an issue where it is incorrectly being decoded to an abstract A rather than a B1 or B2, even though the value store in A will always be a B1 or a B2. I have tried implementing custom init(from decoder: Decoder) and func encode(to encoder: Encoder)s in the subclasses but when I step through Main's decode logic in my running app, I never see those subclasses' implementations being called.

Is this because Main has an A and has no idea to even attempt to decode it as a B1 or a B2? Do I need to call those subclasses decoders specifically? If the latter is that case, those subclasses decoders couldn't call the parent decoder because that would create an infinite loop.

Here is what my code currently looks like:

As far as I know, a modern JPEG decoder produces the same image when given the same input JPEG file.

Normally, we create JPEG files in such a way that the decoded image is an approximation of some input image.

Is the JPEG format flexible enough to allow lossless encoding of arbitrary input images with a custom encoder?

I'd image you'd at least have to fiddle with how quantization tables are used to essentially disable them? Perhaps something else?

(To be clear, I don't mean the special 'lossless' mode in JPEG that many decoders don't support. I am talking about using the default, mainstream code path through the decoder.)

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?

I'm working on a recursive tree of this type

I am still learning scala and attempting to use circe's decoders, but running into a little trouble with a context bound I think. I'm unsure why scala is expecting this implicit argument?

i am trying to get a hardware decoder from media foundation. i know for sure my gpu supports nvdec hardware decoding. i found an example on github which gets the encoder, nvenc without any problem. but when i switch the params to decoder, i either get a bad hresult or a crash. i tried even getting a software decoder by changing the hardware flag, and still bad hresult. any one have an idea what is wrong? i cant think of anything else left for me to try or change

I'm trying to implement the ability to use Azure B2C with Spring Boot's Webflux Security. While there's no official library to actually do this, it was said by someone at Microsoft that Spring Security 5's native features could support Azure B2C. I've followed this repository (though it's not webflux based) to get an idea on pulling this off. The JWT tokens are validated via the audience UUID for an application.

Once I try to actually supply a JWT token to a request, I'm getting a HTTP 401 error stating Authentication failed: Failed to validate the token.

The thing is that in the example repository, they're using the endpoint https://login.microsoftonline.com/{tenantId}/v2.0 for the issuer url.

On the other hand, the JWT token returned from B2C has the issuer https://{tenantName}.b2clogin.com/{tenantId}/v2.0/.

If I use the issuer https://{tenantName}.b2clogin.com/{tenantId}/v2.0/ instead, the JWT decoder won't be able to find the configurations.

So now I feel there's an inconsistency on what the issuer URL actually is, which prevents Webflux from actually being able to perform the authentication.

Here's the code I have for the security.
