Displaying YUV Image in Android

Question

In my application, we need to display the Video frame receives from server to our android application,
Server is sending video data @ 50 frame per second, having encoded

Answer 1

Another way would be using ScriptIntrinsicYuvToRGB, this is more efficient then encoding (and decoding) each time a JPEG

fun yuvByteArrayToBitmap(bytes: ByteArray, width: Int, height: Int): Bitmap {
    val rs = RenderScript.create(this)

    val yuvToRgbIntrinsic = ScriptIntrinsicYuvToRGB.create(rs, Element.U8_4(rs));
    val yuvType = Type.Builder(rs, Element.U8(rs)).setX(bytes.size);
    val input = Allocation.createTyped(rs, yuvType.create(), Allocation.USAGE_SCRIPT);

    val rgbaType = Type.Builder(rs, Element.RGBA_8888(rs)).setX(width).setY(height);
    val output = Allocation.createTyped(rs, rgbaType.create(), Allocation.USAGE_SCRIPT);

    input.copyFrom(bytes);

    yuvToRgbIntrinsic.setInput(input);
    yuvToRgbIntrinsic.forEach(output);

    val bitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888)
    output.copyTo(bitmap)

    input.destroy()
    output.destroy()
    yuvToRgbIntrinsic.destroy()
    rs.destroy()

    return bitmap
}
