Trait cros_codecs::utils::vaapi::StreamInfo

pub(crate) trait StreamInfo {
    fn va_profile(&self) -> Result<i32>;
    fn rt_format(&self) -> Result<u32>;
    fn min_num_surfaces(&self) -> usize;

    fn visible_rect(&self) -> ((u32, u32), (u32, u32));
}

A trait for providing the basic information needed to setup libva for decoding.

Required Methods

fn va_profile(&self) -> Result<i32>

Returns the VA profile of the stream.

fn rt_format(&self) -> Result<u32>

Returns the RT format of the stream.

fn min_num_surfaces(&self) -> usize

Returns the minimum number of surfaces required to decode the stream.

fn coded_size(&self) -> (u32, u32)

Returns the coded size of the surfaces required to decode the stream.

fn visible_rect(&self) -> ((u32, u32), (u32, u32))

Returns the visible rectangle within the coded size for the stream.
