Struct libva::Surface

pub struct Surface {
    display: Rc<Display>,
    id: VASurfaceID,
}

An owned VA surface that is tied to the lifetime of a particular VADisplay

Fields

display: Rc<Display>

id: VASurfaceID

Implementations

impl Surface

pub(crate) fn new(
    display: Rc<Display>,
    rt_format: u32,
    va_fourcc: Option<u32>,
    width: u32,
    height: u32,
    usage_hint: Option<UsageHint>,
    num_surfaces: u32
) -> Result<Vec<Self>>

Create Surfaces by wrapping around a vaCreateSurfaces call. This is just a helper for Display::create_surfaces.

pub fn sync(&self) -> Result<()>

Blocks until all pending operations on the render target have been completed. Upon return it is safe to use the render target for a different picture.

pub fn as_id_vec(surfaces: &[Self]) -> Vec<VASurfaceID>

Convenience function to return a VASurfaceID vector. Useful to interface with the C API where a surface array might be needed.

pub fn query_status(&self) -> Result<Type>

Wrapper over vaQuerySurfaceStatus to find out any pending ops on the render target.

pub fn id(&self) -> VASurfaceID

Returns the ID of this surface.

Trait Implementations

impl Drop for Surface

fn drop(&mut self)

Executes the destructor for this type.
