UniWebViewSnapshotTextureStream

Summary

Represents a live snapshot texture stream owned by a UniWebView.

You do not create an instance of this class directly. Start a stream by calling StartSnapshotTextureStream on a UniWebView instance. The stream owns one live texture and updates it in place after the first native frame is ready. Assign the texture once, clear your Unity reference before cleanup, and call Dispose when the stream is no longer needed.

If the current platform or graphics backend supports neither the optimized stream nor a CPU readback fallback, Texture remains null and IsReady remains false. The stream API does not fall back to the legacy PNG-backed texture APIs. On Android, the optimized native texture path requires OpenGL ES 2 or OpenGL ES 3; under other graphics APIs such as Vulkan, the stream automatically uses a CPU readback fallback with the same behavior at a higher per-frame cost.

Properties Summary

Texture2D Texture { get; }	Gets the live texture updated in place by the stream.
bool IsReady { get; }	Gets whether the stream has received its first usable native texture frame.
int Width { get; }	Gets the current stream texture width in pixels.
int Height { get; }	Gets the current stream texture height in pixels.
Rect Rect { get; }	Gets the local web view rectangle captured by this stream.
long FrameIndex { get; }	Gets the latest uploaded frame index.

Methods Summary

void Stop()	Stops the stream and releases the stream-owned texture.
void Dispose()	Stops the stream and releases the stream-owned texture.

Properties

Texture2D Texture { get; }

Gets the live texture updated in place by the stream.

The value is null until the first native frame is captured and uploaded. The stream owns this texture; do not destroy it manually.

bool IsReady { get; }

Gets whether the stream has received its first usable native texture frame.

int Width { get; }

Gets the current stream texture width in pixels.

int Height { get; }

Gets the current stream texture height in pixels.

Rect Rect { get; }

Gets the local web view rectangle captured by this stream.

long FrameIndex { get; }

Gets the latest uploaded frame index.

Methods

void Stop()

Stops the stream and releases the stream-owned texture.

Calling this method more than once is safe.

void Dispose()

Stops the stream and releases the stream-owned texture.

This is equivalent to Stop and is safe to call more than once.
