    if (mProgram == null || inputFormat.getTarget() != mTarget) {
        initProgram(context, inputFormat.getTarget());
        initParameters();
    }
    // Create output frame
    Frame output = context.getFrameManager().newFrame(inputFormat);
    // Process
    mProgram.process(input, output);
    // Push output
    pushOutput("image", output);
    // Release pushed frame
    output.release();

Example 22 with Frame

use of android.filterfw.core.Frame in project android_frameworks_base by ParanoidAndroid.

the class ToPackedGrayFilter method process.

@Override

    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();
}

Example 23 with Frame

use of android.filterfw.core.Frame in project android_frameworks_base by ParanoidAndroid.

the class ThroughputFilter method process.

@Override
public void process(FilterContext context) {
    // Pass through input frame
    Frame input = pullInput("frame");
    pushOutput("frame", input);
    // Update stats
    ++mTotalFrameCount;

    // Check clock
    if (mLastTime == 0) {
        mLastTime = SystemClock.elapsedRealtime();
    }
    long curTime = SystemClock.elapsedRealtime();
    // Output throughput info if time period is up
    if ((curTime - mLastTime) >= (mPeriod * 1000)) {
        FrameFormat inputFormat = input.getFormat();
        int pixelCount = inputFormat.getWidth() * inputFormat.getHeight();
        Throughput throughput = new Throughput(mTotalFrameCount, mPeriodFrameCount, mPeriod, pixelCount);
        Frame throughputFrame = context.getFrameManager().newFrame(mOutputFormat);
        throughputFrame.setObjectValue(throughput);
        pushOutput("throughput", throughputFrame);
        mLastTime = curTime;
        mPeriodFrameCount = 0;
    }
}
