Inherits from	NSObject
Declared in	VKPacket.h

Overview

VKPacket is an objective-c class of AVPacket structure, but holds only needed properties of AVPacket structure

`– initWithPkt:serial:isFlush:`

Initialize a VKPacket object

- (id)initWithPkt:(AVPacket *)pkt serial:(int)serial isFlush:(BOOL)flush

Parameters

`pkt`	FFmpeg’s structure that stores compressed data, typically exported by demuxers and then passed as input to decoders
`serial`	The identifying number of queue inside stream
`flush`	Flush packet is a special packet and if this value is YES then queues will be flushed
