Fix for return value -12780 when calling VTCompressionSessionEncodeFrame(). You need to pass the `nbytes` into the `CVPixelBufferCreateWithPlanarBytes()` function otherwise you'll get this return value.

	#include "Encoding.h"

	/* ------------------------------------------------------------------- */

	static void output_callback(void* outputCallbackRefCon,
	void* sourceFrameRefCon,
	OSStatus status,
	VTEncodeInfoFlags infoFlags,
	CMSampleBufferRef sampleBuffer);

0x36 / jpeg.c

Created March 25, 2020 21:51

	#if 0
	Reported : 19-Jan-2020
	Fixed in iOS 13.4 with CVE-2020-9768
	AppleJPEGDriverUserClient : mach port use-after-free/type-confusion via race condition

	AppleJPEGDriverUserClient external methods can be used synchronously or asynchronously, when used asynchronously,
	it brings the registered mach port (via registerNotificationPort()) and put it inside jpegRequest data structure,
	and no reference count was taken for this operation. since registerNotificationPort() is not gated, it is
	possible to release the port (if the port got substituted) during the processing of jpeg request and end up
	with dangling pointer passed to _mach_msg_send_from_kernel_proper().
