Note that the buffer provides a pointer to a pointer. This interface cannot modify the pointer of the buffer, but it can modify the content of the buffer.

Attributes

type: The pixel format. See VIDEO_PIXEL_FORMAT.
width: The width of the video, in pixels.
height: The height of the video, in pixels.
yStride: For YUV data, the line span of the Y buffer; for RGBA data, the total data length.
uStride: For YUV data, the line span of the U buffer; for RGBA data, the value is 0.
vStride: For YUV data, the line span of the V buffer; for RGBA data, the value is 0.
yBuffer: For YUV data, the pointer to the Y buffer; for RGBA data, the data buffer.
uBuffer: For YUV data, the pointer to the U buffer; for RGBA data, the value is 0.
vBuffer: For YUV data, the pointer to the V buffer; for RGBA data, the value is 0.
rotation: The clockwise rotation of the video frame before rendering. Supported values include 0, 90, 180, and 270 degrees.
renderTimeMs: The Unix timestamp (ms) when the video frame is rendered. This timestamp can be used to guide the rendering of the video frame. It is required.
avsync_type: Reserved for future use.
metadata_buffer: This parameter only applies to video data in Texture format. The MetaData buffer. The default value is NULL.
metadata_size: This parameter only applies to video data in Texture format. The MetaData size. The default value is 0.
sharedContext: This parameter only applies to video data in Texture format. EGL Context.
textureId: This parameter only applies to video data in Texture format. Texture ID.
matrix: This parameter only applies to video data in Texture format. Incoming 4 × 4 transformational matrix. The typical value is a unit matrix.
metaInfo: The meta information in the video frame. To use this parameter, please technical support.
