Struct y4m::Decoder

pub struct Decoder<R: Read> { /* private fields */ }

YUV4MPEG2 decoder.

Implementations

impl<R: Read> Decoder<R>

pub fn new(reader: R) -> Result<Decoder<R>, Error>

Create a new decoder instance.

pub fn new_with_limits(reader: R, limits: Limits) -> Result<Decoder<R>, Error>

Create a new decoder instance with custom limits.

pub fn read_frame(&mut self) -> Result<Frame<'_>, Error>

Iterate over frames. End of input is indicated by Error::EOF.

pub fn get_width(&self) -> usize

Return file width.

pub fn get_height(&self) -> usize

Return file height.

pub fn get_framerate(&self) -> Ratio

Return file framerate.

pub fn get_pixel_aspect(&self) -> Ratio

Return file pixel aspect.

pub fn get_colorspace(&self) -> Colorspace

Return file colorspace.

NOTE: normally all .y4m should have colorspace param, but there are files encoded without that tag and it’s unclear what should we do in that case. Currently C420 is implied by default as per ffmpeg behavior.

pub fn get_raw_params(&self) -> &[u8]

Return file raw parameters.

pub fn get_bit_depth(&self) -> usize

Return the bit depth per sample

pub fn get_bytes_per_sample(&self) -> usize

Return the number of bytes in a sample
