Example 91 with MutableFrameFormat

use of android.filterfw.core.MutableFrameFormat in project android_frameworks_base by AOSPA.

the class ToPackedGrayFilter method process.

@Override
public void process(FilterContext context) {
    Frame input = pullInput("image");
    FrameFormat inputFormat = input.getFormat();
    FrameFormat outputFormat = convertInputFormat(inputFormat);
    int ow = outputFormat.getWidth();
    int oh = outputFormat.getHeight();
    checkOutputDimensions(ow, oh);
    mProgram.setHostValue("pix_stride", 1.0f / ow);
    // Do the RGBA to luminance conversion.
    MutableFrameFormat tempFrameFormat = inputFormat.mutableCopy();
    tempFrameFormat.setDimensions(ow / 4, oh);
    Frame temp = context.getFrameManager().newFrame(tempFrameFormat);
    mProgram.process(input, temp);
    // Read frame from GPU to CPU.
    Frame output = context.getFrameManager().newFrame(outputFormat);
    output.setDataFromFrame(temp);
    temp.release();
    // Push output and yield ownership.
    pushOutput("image", output);
    output.release();
}
