Class VideoFrame

The alpha channel data output by using portrait segmentation algorithm. This data matches the size of the video frame, with each pixel value ranging from [0,255], where 0 represents the background and 255 represents the foreground (portrait). By setting this parameter, you can render the video background into various effects, such as transparent, solid color, image, video, etc. In custom video rendering scenarios, ensure that both the video frame and alphaBuffer are of the Full Range type; other types may cause abnormal alpha data rendering. Make sure that alphaBuffer is exactly the same size as the video frame (width × height), otherwise it may cause the app to crash.

When the video frame contains alpha channel data, it represents the relative position of alphaBuffer and the video frame. See AlphaStitchMode.

Reserved for future use.

The height of the video, in pixels.

This parameter only applies to video data in Texture format. Incoming 4 × 4 transformational matrix. The typical value is a unit matrix.

The meta information in the video frame. To use this parameter, contact.

This parameter only applies to video data in Texture format. The MetaData buffer. The default value is NULL.

This parameter only applies to video data in Texture format. The MetaData size. The default value is 0.

The Unix timestamp (ms) when the video frame is rendered. This timestamp can be used to guide the rendering of the video frame. This parameter is required.

The clockwise rotation of the video frame before rendering. Supported values include 0, 90, 180, and 270 degrees.

This parameter only applies to video data in Texture format. Texture ID.

The pixel format. See VideoPixelFormat.

For YUV data, the pointer to the U buffer; for RGBA data, the value is 0.

For YUV data, the line span of the U buffer; for RGBA data, the value is 0. When dealing with video data, it is necessary to process the offset between each line of pixel data based on this parameter, otherwise it may result in image distortion.

For YUV data, the pointer to the V buffer; for RGBA data, the value is 0.

For YUV data, the line span of the V buffer; for RGBA data, the value is 0. When dealing with video data, it is necessary to process the offset between each line of pixel data based on this parameter, otherwise it may result in image distortion.

The width of the video, in pixels.

For YUV data, the pointer to the Y buffer; for RGBA data, the data buffer.

For YUV data, the line span of the Y buffer; for RGBA data, the total data length. When dealing with video data, it is necessary to process the offset between each line of pixel data based on this parameter, otherwise it may result in image distortion.
