Struct cros_codecs::decoder::StreamInfo

pub struct StreamInfo {
    pub format: DecodedFormat,
    pub coded_resolution: Resolution,
    pub display_resolution: Resolution,
    pub min_num_surfaces: usize,
}

Information about the current stream.

This is static information obtained from the stream itself about its requirements. It does not reflect the current settings of the decoder.

Fields

format: DecodedFormat

Pixel format for the output frames expected by the decoder.

coded_resolution: Resolution

Coded resolution of the stream, i.e. minimum size of the frames to be decoded into.

display_resolution: Resolution

Display resolution of the stream, i.e. the part of the decoded frames we want to display.

min_num_surfaces: usize

Minimum number of output surfaces required for decoding to proceed.

Codecs keep some frames as references and cannot decode immediately into them again after they are returned. Allocating at least this number of frames guarantees that the decoder won’t starve from output surfaces.

Trait Implementations

impl Clone for StreamInfo

fn clone(&self) -> StreamInfo

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
