Struct AssetPtr 

pub struct AssetPtr<T> { /* private fields */ }

A managed iasset pointer.

Implementations

impl<T> AssetPtr<T>

pub fn adopt(lp: *mut T) -> Self

Attach to an iasset pointer and increment its reference count.

impl<T: NamedInterface> AssetPtr<T>

Attempt to construct Self via a conversion.

pub fn try_from<U>(other: &mut AssetPtr<U>) -> Result<Self>

Retrieve a supported interface of the managed pointer.

Example:

let mut site = AssetPtr::adopt(external_ptr);
let source = AssetPtr::<video_source>::try_from(&mut site);
assert!(source.is_ok());

Methods from Deref<Target = video_destination>

pub fn is_alive(&self) -> bool

Whether this instance of video_renderer is attached to a DOM element and is capable of playing.

pub fn start_streaming( &mut self, frame_size: (i32, i32), color_space: COLOR_SPACE, src: Option<&video_source>, ) -> Result<()>

Start streaming/rendering.

• frame_size - the width and the height of the video frame.
• color_space - the color space format of the video frame.
• src - an optional custom video_source interface implementation, provided by the application.

pub fn stop_streaming(&mut self) -> Result<()>

Stop streaming.

pub fn render_frame(&mut self, data: &[u8]) -> Result<()>

Render the next frame.

pub fn render_frame_with_stride( &mut self, data: &[u8], stride: u32, ) -> Result<()>

Render the next frame with the given stride.
