BitReader

#GstBitReader provides a bit reader that can read any number of bits from a memory buffer. It provides functions for reading any number of bits into 8, 16, 32 and 64 bit variables.

class BitReader {

GstBitReader cInstance;

bool getBitsUint16(ushort val, uint nbits);

bool getBitsUint32(uint val, uint nbits);

bool getBitsUint64(ulong val, uint nbits);

bool getBitsUint8(ubyte val, uint nbits);

uint getPos();

uint getRemaining();

uint getSize();

void init_(ubyte[] data);

bool peekBitsUint16(ushort val, uint nbits);

bool peekBitsUint32(uint val, uint nbits);

bool peekBitsUint64(ulong val, uint nbits);

bool peekBitsUint8(ubyte val, uint nbits);

bool setPos(uint pos);

bool skip(uint nbits);

bool skipToByte();

Functions

getBitsUint16 bool getBitsUint16(ushort val, uint nbits): Read nbits bits into val and update the current position.
getBitsUint32 bool getBitsUint32(uint val, uint nbits): Read nbits bits into val and update the current position.
getBitsUint64 bool getBitsUint64(ulong val, uint nbits): Read nbits bits into val and update the current position.
getBitsUint8 bool getBitsUint8(ubyte val, uint nbits): Read nbits bits into val and update the current position.
getPos uint getPos(): Returns the current position of a #GstBitReader instance in bits.
getRemaining uint getRemaining(): Returns the remaining number of bits of a #GstBitReader instance.
getSize uint getSize(): Returns the total number of bits of a #GstBitReader instance.
init_ void init_(ubyte[] data): Initializes a #GstBitReader instance to read from data. This function can be called on already initialized instances.
peekBitsUint16 bool peekBitsUint16(ushort val, uint nbits): Read nbits bits into val but keep the current position.
peekBitsUint32 bool peekBitsUint32(uint val, uint nbits): Read nbits bits into val but keep the current position.
peekBitsUint64 bool peekBitsUint64(ulong val, uint nbits): Read nbits bits into val but keep the current position.
peekBitsUint8 bool peekBitsUint8(ubyte val, uint nbits): Read nbits bits into val but keep the current position.
setPos bool setPos(uint pos): Sets the new position of a #GstBitReader instance to pos in bits.
skip bool skip(uint nbits): Skips nbits bits of the #GstBitReader instance.
skipToByte bool skipToByte(): Skips until the next byte.
