Flickering during streaming #602

Hi Saki,

I have built an application using this library.

I'm using Android Studio version 3.3.2. I have custom hardware that transfers data in YUV format.

But I'm getting flickering and sometimes the frame gets cut.

To compare I have used one of the webcam. Webcam streams just fine,

After debugging I have found out that the webcam provides MJPEG data whereas my hardware provides data in YUV format.

With few of the applications available on the play store I'm getting smooth streaming but with usbcameratest8 I'm facing this issue.

Can you please help in this regards?

I was getting same issue and I fixed it by increasing number of libuvc transfer buffers ie. in libuvc_internal.h

define LIBUVC_NUM_TRANSFER_BUFS 40
