Problem when GPUImageView.setImage continuously

[hoozh]

Hi everyone

I use GPUImageView to preview camera video frames, because the camera is not standard Android camera, it captures data from USB connection or network stream. so I don't use GPUImage.setUpCamera feature.

my app preview the image frames with GPUImageView.setImage method. I found that if the objects in front of the camera lens move quickly, the image will be splitted.

I think that's because GPUImage rendering is slower than image frames feeding.

Am i right?

How to known if the rendering is finishhed.

I also checked if GLSurfaceView is dirty before setImage

Maybe you need to setup a vsync situation to swap graphics buffers ?

This is how grafika does it:

/**
 * Calls eglSwapBuffers.  Use this to "publish" the current frame.
 *
 * @return false on failure
 */
public boolean swapBuffers(EGLSurface eglSurface) {
    return EGL14.eglSwapBuffers(mEGLDisplay, eglSurface);
}

Sorry?

The GPUImage and GPUImageFilter apply and draw data from the camera are very slow or if apply group filter. I have modified some class of the GPUImageFilter end render, It runs very fast. If you want I can send to you my source code, I do not post it to here because of code very long.

do a Pull Request?

@monxarat I also encountered this problem. I was very slow in camera preview at high resolution. How do you solve this problem? Can you send me the source code? Email: [email protected]
