Attributes

type

The video type. See VIDEO_BUFFER_TYPE.

format

The pixel format. See VIDEO_PIXEL_FORMAT.

buffer

Video frame buffer.

stride

Line spacing of the incoming video frame, which must be in pixels instead of bytes. For textures, it is the width of the texture.

height

Height of the incoming video frame.

eglContext

This parameter only applies to video data in Texture format.

When using the OpenGL interface (javax.microedition.khronos.egl.*) defined by Khronos, set eglContext to this field.
When using the OpenGL interface (android.opengl.*) defined by Android, set eglContext to this field.

eglType

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

textureId

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

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.

d3d11_texture_2d

This parameter only applies to video data in Windows Texture format. It represents a pointer to an object of type ID3D11Texture2D, which is used by a video frame.

texture_slice_index

This parameter only applies to video data in Windows Texture format. It represents an index of an ID3D11Texture2D texture object used by the video frame in the ID3D11Texture2D array.

cropLeft

Raw data related parameter. The number of pixels trimmed from the left. The default value is 0.

This parameter only applies to raw video data.

cropTop

Raw data related parameter. The number of pixels trimmed from the top. The default value is 0.

This parameter only applies to raw video data.

cropRight

Raw data related parameter. The number of pixels trimmed from the right. The default value is 0.

This parameter only applies to raw video data.

cropBottom

Raw data related parameter. The number of pixels trimmed from the bottom. The default value is 0.

This parameter only applies to raw video data.

rotation

Raw data related parameter. The clockwise rotation of the video frame. You can set the rotation angle as 0, 90, 180, or 270. The default value is 0.

timestamp

Timestamp (ms) of the incoming video frame. An incorrect timestamp results in frame loss or unsynchronized audio and video.
