Struct AndroidNativeWindowHandle 

pub struct AndroidNativeWindowHandle { /* private fields */ }

Available on Android only.

ANativeWindow* encoder input surface.

Implementations

impl AndroidNativeWindowHandle

pub unsafe fn try_from_raw( window: *mut c_void, keep_alive: Option<KeepAlive>, ) -> Result<Self, InvalidHandleError>

Wrap an ANativeWindow* encoder input surface. Borrowing: the handle is stored non-owningly, this type has no Drop, and every obligation below extends to each Clone.

Safety

• window must point to a live ANativeWindow on which the caller holds a reference — from ANativeWindow_fromSurface, AMediaCodec_createInputSurface, or an equivalent. Null is rejected as InvalidHandleError::NullPointer and is not a caller obligation.
• Refcount: no ANativeWindow_acquire is issued and there is no Drop that would ANativeWindow_release. The caller’s reference must outlive this value and every Clone of it — park it in keep_alive, or hold it directly when that is None. Releasing while a clone survives is a use-after-free.
• This is an output-side handle: the interop layer renders into it and never treats it as an import source. The caller must not concurrently dequeue or lock buffers from the same window, since ANativeWindow has a single producer slot.
• AndroidNativeWindowHandle is Send + Sync; the caller asserts the window may be driven from the interop thread rather than the one that created it.
