Struct BitReader 

pub struct BitReader<R: BufRead + Clone> { /* private fields */ }

Reads H.264 bitstream syntax elements from an RBSP representation (no NAL header byte or emulation prevention three bytes).

Implementations

impl<R: BufRead + Clone> BitReader<R>

pub fn new(inner: R) -> Self

pub fn reader(&mut self) -> Option<&mut R>

Borrows the underlying reader if byte-aligned.

pub fn into_reader(self) -> R

Unwraps internal reader and disposes of BitReader.

Warning

Any unread partial bits are discarded.

Trait Implementations

impl<R: BufRead + Clone> BitRead for BitReader<R>

fn read_ue(&mut self, name: &'static str) -> Result<u32, BitReaderError>

Reads an unsigned Exp-Golomb-coded value, as defined in the H.264 spec.

fn read_se(&mut self, name: &'static str) -> Result<i32, BitReaderError>

Reads a signed Exp-Golomb-coded value, as defined in the H.264 spec.

fn read_bool(&mut self, name: &'static str) -> Result<bool, BitReaderError>

Reads a single bit, as in [crate::bitstream_io::read::BitRead::read_bool].

fn read<U: Numeric>( &mut self, bit_count: u32, name: &'static str, ) -> Result<U, BitReaderError>

Reads an unsigned value from the bitstream with the given number of bytes, as in crate::bitstream_io::read::BitRead::read.

fn read_to<V: Primitive>( &mut self, name: &'static str, ) -> Result<V, BitReaderError>

Reads a whole value from the bitstream whose size is equal to its byte size, as in crate::bitstream_io::read::BitRead::read_to.

fn skip( &mut self, bit_count: u32, name: &'static str, ) -> Result<(), BitReaderError>

Skips the given number of bits in the bitstream, as in crate::bitstream_io::read::BitRead::skip.

fn has_more_rbsp_data( &mut self, name: &'static str, ) -> Result<bool, BitReaderError>

Returns true if positioned before the RBSP trailing bits.

fn finish_rbsp(self) -> Result<(), BitReaderError>

Consumes the reader, returning error if it’s not positioned at the RBSP trailing bits.

fn finish_sei_payload(self) -> Result<(), BitReaderError>

Consumes the reader, returning error if this sei_payload message is unfinished.
