Fields

context: Rc<Context>

A VAContext from which we can decode from.

config: Config

The VAConfig that created the context. It must kept here so that it does not get dropped while it is in use.

surface_pool: SurfacePoolHandle

A pool of surfaces. We reuse surfaces as they are expensive to allocate.

min_num_surfaces: usize

The number of surfaces required to parse the stream.

display_resolution: Resolution

The decoder current display resolution.

map_format: Rc<VAImageFormat>

The image format we will use to map the surfaces. This is usually the same as the surface’s internal format, but occasionally we can try mapping in a different format if requested and if the VA-API driver can do it.

rt_format: u32

The rt_format parsed from the stream.

profile: i32

The profile parsed from the stream.
