Question

When trying to convert the byte[] of Camera.onPreviewFrame to Bitamp using BitmapFactory.decodeByteArray gives me an error SkImageDecoder::Factory returned null

Following is my code:

public void onPreviewFrame(byte[] data, Camera camera) {
    Bitmap bmp=BitmapFactory.decodeByteArray(data, 0, data.length);
}

Answer 1

I found the answer after a long time. Here it is…

Instead of using BitmapFactory, I used my custom method to decode this byte[] data to a valid image format. To decode the image to a valid image format, one need to know what picture format is being used by the camera by calling camera.getParameters().getPictureFormat(). This returns a constant defined by ImageFormat. After knowing the format, use the appropriate encoder to encode the image.

In my case, the byte[] data was in the YUV format, so I looked for YUV to BMP conversion and that solved my problem.
