  arm/aarch64 : Improve scheduling in the avg form of h264_qpel
  Don't use the loaded registers directly, avoiding stalls on in
  
  order cores. Use vrhadd.u8 with q registers where easily possible.

• How to encode video with ffmpeg form videocapture Mat

  26 août 2022, par chromize

  I'm trying to make video editor tool.

  


  [Environment]
C#
WPF
OpenCVSharp4.5

  


  When encoding video,I have to set some config.(fps/width/height/codec/bitrate/field-order)
But,can't set field-order with opencv's videowriter.

  


          VideoWriter video = new VideoWriter(
            outPutFilePath,
            VideoCaptureAPIs.FFMPEG,
            VideoWriter.FourCC(Char.Parse("M"),
            Char.Parse("P"),
            Char.Parse("4"),
            Char.Parse("V"),
            fps,
            new OpenCvSharp.Size(Width, Height),
            true);
            for (int movePos = StartFrame; movePos < EndFrame; movePos++)
            {
                PosFrames = movePos;
                Mat mat = SetMatFromFrameNo(PosFrames);

                video.Write(mat);
               Cv2.WaitKey(1);
            }


  


  so,I'm trying to use piped ffmpeg.
But I have no idea.

  


  Could you tell how to encode video From VideoCaptures. thanks.

  


• Introducing Improvements to the Opt-Out Form Feature

  18 septembre 2022, par Ben — About

  Matomo includes a built-in opt-out form that you can add to your website so you can provide your visitors with the choice to opt-out of Matomo tracking. Up until Matomo 4.12.0 the built-in opt-out form relied on iFrame technology which has become increasingly problematic due to browser changes and restrictions on setting third-party cookies.

  With our privacy-first approach, we’ve known for some time that we would eventually need a new way to provide this important opt-out functionality that would work most reliably in the myriad of contexts our users rely on it for.

  Embedding the opt-out form

  Matomo 4.12.0 introduces an improved opt-out. This provides two new options for embedding the opt-out on your website, either using the Matomo tracker code or as self-contained code.

  

  As with the iFrame method, the built-in opt-out code can be styled in Matomo to match your website, and provides a snippet which you can add to your website to show the opt-out feature to your users.

  Find out how to customise the opt-out form.

  Customising the opt-out form

  

  What does this mean for existing opt-out forms ?

  Although it is no longer possible to generate new iFrame embed code using the Matomo UI, the underlying opt-out feature is still fully supported and any existing iFrame opt-out form code embedded in websites will still work as before. It is recommended to migrate to one of the new opt-out form options as browser support for the iFrame opt-out will continue to decrease.

  To read more in depth information about the new opt-out functionality please refer to our new developer documentation for tracking opt-out.
