Hey guys, I just submitted pull request #1326. This adds support to Accord.Video.DirectShow.VideoCaptureDevice for programatically getting/setting signal processor properties (i.e. gain, brightness, hue, etc). Can I get this merged?

@dotChris90
hello accord guys - does ACCORD give user the possibility to use "http://accord-framework.net/docs/html/T_Accord_Statistics_Models_Regression_NonlinearRegression.htm" (this example) but without! computing the Gradient? And do Accord has some classes for finding the global Minimum of the corresponding Regression error function (not just local)?

Hi team, is there any documentation regarding which methods can throw which exceptions? For example PolynomialLeastSquares can throw a SingularMatrixException on Learn. I couldn't find anything on the website, thanks.

Anybody knows how to fit data with a 4PL model (or even better with 5PL)? I tried using LevenbergMarquardt but the results are poor. You can check my code on StackOverflow ( https://stackoverflow.com/questions/52535521/fitting-4pl-with-levenbergmarquardt )

Hi! I've made a small fix for issue #1659 (that I also created ;) )... but I'm new to github and can't push my branch ... I get
git push --set-upstream origin C45_invalid_leafs_fix
remote: Permission to accord-net/framework.git denied to marshmit.
fatal: unable to access 'https://github.com/accord-net/framework.git/': The requested URL returned error: 403
... probably I'm not doing it the wrong way ... but the pull request help just says ... push your branch & create pull request ... I'm not understanding what I'm doing wrong
Marwin Schmitt
@marshmit
So I fork accord on my account, submitted the branch there and then did the pull request ... is that the way it should be done? If so maybe it should be put on the contribution page...
also I get a message that two checks failed. "AppVeyor build failed" and "The Travis CI build failed" - from what I can see in the messages things that have really nothing to do with my code ...

@A7250AG
I've been looking through the documentation for a few hours but haven't found anything promising yet: does Accord.Audio support resampling of audio signals?
If not, is that a feature that would be appropriate to add to Accord.Audio?
I'm investigating an alternative library for my use case (https://github.com/ar1st0crat/NWaves) but am open to trying my hand at adding resampling to Accord.Audio

Is there any intentions to migrate accord imaging to System.Drawing.Commons? I'm struggling with a standard .net core 2.0 library that uses accord for image procesing, and it dependency with CoreCompat.System.Drawing

@KapilDave

I am new in camera programming. For learning purpose I have download Accord-Framework C# source code.

Thus if we have JPG or MPEG Stream then we can easily display in Accord.Controls.VideoSourcePlayer.

But if we have FFMPEG Stream then how can we display in Accord.Controls.VideoSourcePlayer.

Please anyone can guide me?

Thanks in advance

I might be at the wrong forum - just let me know and I will be on my way. I am using Accord.Video.FFMPEG to create videos in a C# project using Bitmaps as sources. After a few videos has been created (each 5-15 minutes long, 30 fps, FHD, compressed using x264) I get an error: Out of memory. External component has thrown an exception. [libx264 @ 0767eb40] using cpu capabilities: MMX2 SSE2Fast SSSE3 SSE4.2 AVX FMA3 AVX2 LZCNT BMI2 x264 [error]: malloc of size 10891456 failed System.AccessViolationException: 'Attempted to read or write protected memory. This is often an indication that other memory is corrupt.' - To me it seems that when a videofilewriter is flushed, closed and disposed, something remains and after about 5-20 of these has been created (one at a time, disposed before next is created) memory slowly gets exhausted. Is there a known memory leak? Is there a method to reinitialize ffmpeg libraries or do I have to restart the application every time this happens?
Versions used: .NET Framework 4.7.2, Accord.Video.FFMPEG from Nuget Runtime version: v4.0.30319, Version: 3.8.0.0
I also had problems using this nuget package in a .NET Core solution, but got it working in .NET Framework 4.7.2... which is why I use .NET Framework for this solution right now.

@Darlanio
I guess I will check back here once per day for the next few weeks...
Stefan Alenius
@Darlanio
Switching to VideoCodec.MPEG4 made the solution stable, but bitrate needs to be increased a lot with this codec to get acceptable results... would be better if x264 would work properly.

Delay in preview of webcam, FPS drop on live preview and In video recording, video get pixelated when user select high resolution(1920 * 1080 : 60 FPS)

Issue 1: Delay in preview of webcam, FPS drop on live preview

On high resolution i am facing issue of delay in preview of webcam, FPS drop on live preview in AForge.Video.DirectShow(Version=2.2.5.0).
I am using AForge.Video.DirectShow for getting camera feed in WPF c# application. On high resolution(1920 * 1080 : 60 FPS) user can observe delay in preview of webcam. On normal resolution preview is look good. But when user select higher resolution current frame rate is drooping and user can observe delay in preview of webcam.

This is event for get camera frame and assign to picture box and calculation for get framerate.
https://prnt.sc/26jzu5c

Issue 2 video get pixelated when user select high resolution(1920 * 1080 : 60 FPS)

For video recording i have used Accord.Video.FFMPEG.VideoFileWriter(Version=3.8.0.0) package but in this video get pixelated when user select high resolution(1920 1080 : 60 FPS)
In this screen shoot we can see that its pixelated video on high resolution(1920
1080 : 60 FPS)
https://prnt.sc/26jztyk

This is normal preview from webcam where cant notice any pixelated feed on high resolution(1920 * 1080 : 60 FPS)
https://prnt.sc/26jzumb

This is button click event where I am creating VideoFileWriter object for creating video
https://prnt.sc/26jzuwv

This is callback event from AForge.Video.DirectShow library for getting each frame from webcam
https://prnt.sc/26jzv3p

Please let me know if I can overcome from this issue, Other suggestion is also welcome
