Mediacodec and camera, color space incorrect

Question

By referring Aegonis\'s work 1 and work 2, I also got the H.264 stream , but the color is not correct. I am using HTC Butterfly for development. Here is part of my code:

Answer 1

Got it, now the color looks good, the test is based on HTC Butterfly. When set the resolution to 320x240, your color transform should looks like:

    System.arraycopy(input, 0, output, 0, frameSize);
    for (int i = 0; i < (qFrameSize); i++) {  
        output[frameSize + i*2] = (input[frameSize + qFrameSize + i - 32 - 320]);  
        output[frameSize + i*2 + 1] = (input[frameSize + i - 32 - 320]);            
    }

for resolution 640x480 and above,

System.arraycopy(input, 0, output, 0, frameSize);    
    for (int i = 0; i < (qFrameSize); i++) {  
        output[frameSize + i*2] = (input[frameSize + qFrameSize + i]);  
        output[frameSize + i*2 + 1] = (input[frameSize + i]);   
    } 

For the frame rate issue, we can use the getSupportedPreviewFpsRange() to check the supported frame rate range of our device as:

List fpsRange = parameters.getSupportedPreviewFpsRange();
for (int[] temp3 : fpsRange) {
System.out.println(Arrays.toString(temp3));}

And the following setting works correct when play the encoded H.264 ES,

parameters.setPreviewFpsRange(29000, 30000);    
//parameters.setPreviewFpsRange(4000,60000);//this one results fast playback when I use the FRONT CAMERA
