Implementations

impl AvPixelFormat

pub fn name(&self) -> &'static str

Return the name of this pixel format.

pub fn pix_fmt(&self) -> c_int

Return the avcodec profile id, which can be matched against AV_PIX_FMT_*.

Note that this is not the same as a fourcc.

pub fn fourcc(&self) -> [u8; 4]

Return the fourcc of the pixel format, or a series of zeros if its fourcc is unknown.

pub fn line_size(&self, width: u32, plane: usize) -> Result<usize, AvError>

Given the width and plane index, returns the line size (data pointer increment per row) in bytes.

pub fn plane_sizes<I: IntoIterator<Item = u32>>( &self, linesizes: I, height: u32 ) -> Result<Vec<usize>, AvError>

Given an iterator of line sizes and height, return the size required for each plane’s buffer in bytes.
