Local blur doesn't work using onCaptureVideoFrame lib-raw-data in android about api-examples HOT 5 CLOSED

For local blur, you may need to process it from "onRenderVideoFrame".

Just a question, for your project, do you check if your blur is take effect. But just can't push the blurred bitmap back to SDK?

from api-examples.

onRenderVideoFrame is for remote frame, it even has uid. Its not for local blur. Also we use onCaptureVideoFrame in old sdk and it works just fine.

Yes blurred data can't be pushed back to new SDK, that's the problem. In old SDK when you change data array's content it changes the frame itself.

It has been fix on dev/3.4.0 branch.

you could find below code for correction:

void writebackVideoFrame(VideoFrame &videoFrame, void *byteBuffer)
{
    if (byteBuffer == nullptr)
    {
        return;
    }

    int width = videoFrame.width;
    int height = videoFrame.height;
    size_t widthAndHeight = (size_t) videoFrame.yStride * height;

    memcpy(videoFrame.yBuffer, byteBuffer, widthAndHeight);
    memcpy(videoFrame.uBuffer, (uint8_t *) byteBuffer + widthAndHeight, widthAndHeight / 4);
    memcpy(videoFrame.vBuffer, (uint8_t *) byteBuffer + widthAndHeight * 5 / 4,
           widthAndHeight / 4);
}

okay that solved it, thank you. when will this pushed to master branch?
