test_cvbuffer.m

vtenc has huge memory leaks on OSX 10.9 (and probably on 10.8).
This is due to the fact that the callback provided to
CVPixelBufferCreateWithPlanarBytes is never called even if the CVPixelBufferRef
is released.

To reproduce the issue (tested on OSX 10.9):
* gst-launch-1.0 videotestsrc ! vtenc_h264 ! fakesink
* watch your memory explode

The behaviour of the CVPixelBufferRef API can also be reproduced with the
attached sample code.

Note that CVPixelBufferCreateWithBytes works and calls its callback when
released.
