Struct ffmpeg::swscale::SwConverter

pub struct SwConverter {
    sws_context: *mut SwsContext,
    src_pix_format: c_int,
    dst_pix_format: c_int,
}

A struct able to copy a decoded AvFrame into an OutputBuffer’s memory, converting the pixel format if needed.

Fields

sws_context: *mut SwsContext

src_pix_format: c_int

dst_pix_format: c_int

Implementations

impl SwConverter

pub fn new( width: usize, height: usize, src_pix_format: c_int, dst_pix_format: c_int ) -> Result<Self>

Create a new format converter that will convert frames from src_format to dst_format.

width and height are the coded size of the frames to be converted. The source and target must have the same size in pixels.

pub fn convert( &mut self, src: &AvFrame, dst: &mut AvFrame ) -> Result<(), ConversionError>

Copy src into dst while converting its pixel format according to the parameters the frame converter was created with.

dst must be a writable frame with the same dimensions as src and the same format as dst_pix_format passed to the constructor.

Note that empty dst is not currently allowed as this function does not handle allocation.
