class H264BitReader
Defined at line 22 of file ../../src/media/third_party/chromium_media/media/video/h264_bit_reader.h
A class to provide bit-granularity reading of H.264 streams.
This is not a generic bit reader class, as it takes into account
H.264 stream-specific constraints, such as skipping emulation-prevention
bytes and stop bits. See spec for more details.

void H264BitReader ()Defined at line 11 of file ../../src/media/third_party/chromium_media/media/video/h264_bit_reader.cc
void ~H264BitReader ()Defined at line 19 of file ../../src/media/third_party/chromium_media/media/video/h264_bit_reader.cc
bool Initialize (const uint8_t * data, off_t size)Initialize the reader to start reading at |data|, |size| being size
of |data| in bytes.
Return false on insufficient size of stream..
TODO(posciak,fischman): consider replacing Initialize() with
heap-allocating and creating bit readers on demand instead.

bool ReadBits (int num_bits, int * out)Read |num_bits| next bits from stream and return in |*out|, first bit
from the stream starting at |num_bits| position in |*out|.
|num_bits| may be 1-32, inclusive.
Return false if the given number of bits cannot be read (not enough
bits in the stream), true otherwise.

off_t NumBitsLeft ()Return the number of bits left in the stream.
