[android-developers] Re: converting RGB565 byte array to integer buffer generate wrong results
In the preview, the data is not RGB. It is yuv_420 or a similar format. Query the camera-parameters for the exact format and decode the data accordingly. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

In the "..." part of my original post, I did call "param.setPreviewFormat(PixelFormat.RGB_565)" to explicitly set the pixel format of the preview. I verified it by decoding the resulting byte buffer using an RGB_565-encoded bitmap "bmp=new Bitmap.createBitmap(320,480, Bitmap.Config.RGB_565)" and display the decoded bitmap to an imageview; the image looked ok. So, I am reasonably confident that the preview is RGB_565 encoded. Can anything else in my code mess up the decoding/recording? thanks Qianqian -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

By inserting byteBuf.order(ByteOrder.LITTLE_ENDIAN); before saving the buffer, the results became reasonable. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

Don't count on the hardware of the camera that it can handle RGB. Just get the preview-format and decode it accordingly (yuv format). -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
