video received from ipad/iphone does not show properly about idoubs HOT 6 CLOSED

this problem can be fixed by add this code
        bufferPtr += 16 * sizeof(UInt8);
 to the callback function 
- (void)captureOutput in InCallViewController.m, as below

=================
- (void)captureOutput:(AVCaptureOutput *)captureOutput 
didOutputSampleBuffer:(CMSampleBufferRef)sampleBuffer 
fromConnection:(AVCaptureConnection *)connection {

    CVPixelBufferRef pixelBuffer = CMSampleBufferGetImageBuffer(sampleBuffer);
    if(CVPixelBufferLockBaseAddress(pixelBuffer, 0) == kCVReturnSuccess){
        UInt8 *bufferPtr = (UInt8 *)CVPixelBufferGetBaseAddress(pixelBuffer);
    bufferPtr += 16 * sizeof(UInt8);
        size_t buffeSize = CVPixelBufferGetDataSize(pixelBuffer);

        if(self->producerFirstFrame){ // Hope will never change
........
====================

Thanks for the patch. Sorry for not being able to give you support because I am 
abroad and don't have a MAC to fix issues.

I changed the code follow by [email protected] comments. The video display 
properly.
But the video quality downgrade（fade-to-black, mosaic.

That is also because the iPhone doesn't have the power to send high quality 
video to the server and the front camera is of lesser quality then the back 
camera.

Fixed in iDoubs v2.x.

I have fixed the application on iphone ,but when I make a video call with my 
friend,the pictures are very poor,I think this is the problem of the resolution 
ratio，encoding and decoding,right?So,what should I do if I want the picture 
to be clear ? Can you help me ?
