I420Frame (Video Android 5.1.2)

java.lang.Object
- com.twilio.video.I420Frame

```
public class I420Frame
extends Object
```
A YUV frame in the I420 format. A frame can be represented as a ByteBuffer array of Y, U, and V pixel data with an array of strides for each plane or as a texture.
When a frame is represented as a texture, textureId will be set to a positive non zero value with yuvPlanes and yuvStrides set to null. The YUV data can be extracted from the texture using an instance of tvi.webrtc.YuvConverter and the samplingMatrix.
When a frame is represented as an array of ByteBuffer, textureId will be 0, yuvPlanes contains the YUV pixel data, and yuvStrides contains each plane's stride.

Field Summary

Fields
Modifier and Type	Field and Description
`int`	`height` Height of frame
`int`	`rotationDegree` The degree that the frame must be rotated clockwise to be rendered correctly.
`float[]`	`samplingMatrix` Matrix that transforms standard coordinates to their proper sampling locations in the texture.
`int`	`textureId` Id of the texture the frame is bound to.
`int`	`width` Width of frame
`ByteBuffer[]`	`yuvPlanes` Array of pixel data for each plane.
`int[]`	`yuvStrides` Array of strides for each plane.

    Width of frame
  - height
```
public final int height
```
    Height of frame
  - yuvStrides
```
public final int[] yuvStrides
```
    Array of strides for each plane. This field is null when the frame is represented as a texture.
    yuvStrides[0] - Y stride.
    yuvStrides[1] - U stride.
    yuvStrides[2] - V stride.
  - yuvPlanes
```
public final ByteBuffer[] yuvPlanes
```
    Array of pixel data for each plane. This field is null when the frame is represented as a texture.
    yuvPlanes[0] - Y pixel data.
    yuvPlanes[1] - U pixel data.
    yuvPlanes[2] - V pixel data.
  - rotationDegree
```
public int rotationDegree
```
    The degree that the frame must be rotated clockwise to be rendered correctly.
  - textureId
```
public int textureId
```
    Id of the texture the frame is bound to. This field is zero when the frame is represented as buffer.
  - samplingMatrix
```
public final float[] samplingMatrix
```
    Matrix that transforms standard coordinates to their proper sampling locations in the texture. This transform compensates for any properties of the video source that cause it to appear different from a normalized texture. This matrix does not take rotationDegree into account.
- Method Detail
  - rotatedWidth
```
public int rotatedWidth()
```
    Returns the width of the frame based on the current rotationDegree.
  - rotatedHeight
```
public int rotatedHeight()
```
    Returns the height of the frame based on the current rotationDegree.
  - release
```
public void release()
```
    Called when a VideoRenderer has completed rendering a frame. This must be invoked for each frame to ensure that resources are not leaked.
  - toString
