    Allocates an empty I010Buffer suitable for an image of the given dimensions.
    
    Parameters:
    
    width - width.
    
    height - height.
    
    Returns:
    
    an empty I010Buffer.
  - getDataY
```
public java.nio.ByteBuffer getDataY()
```
    Description copied from interface: VideoFrame.I420Buffer
    
    Returns a direct ByteBuffer containing Y-plane data. The buffer capacity is at least getStrideY() * getHeight() bytes. The position of the returned buffer is ignored and must be 0. Callers may mutate the ByteBuffer (eg. through relative-read operations), so implementations must return a new ByteBuffer or slice for each call.
    
    Specified by:
    
    getDataY in interface VideoFrame.I420Buffer
  - getDataV
```
public java.nio.ByteBuffer getDataV()
```
    Description copied from interface: VideoFrame.I420Buffer
    
    Returns a direct ByteBuffer containing V-plane data. The buffer capacity is at least getStrideV() * ((getHeight() + 1) / 2) bytes. The position of the returned buffer is ignored and must be 0. Callers may mutate the ByteBuffer (eg. through relative-read operations), so implementations must return a new ByteBuffer or slice for each call.
    
    Specified by:
    
    getDataV in interface VideoFrame.I420Buffer
  - getDataU
```
public java.nio.ByteBuffer getDataU()
```
    Description copied from interface: VideoFrame.I420Buffer
    
    Returns a direct ByteBuffer containing U-plane data. The buffer capacity is at least getStrideU() * ((getHeight() + 1) / 2) bytes. The position of the returned buffer is ignored and must be 0. Callers may mutate the ByteBuffer (eg. through relative-read operations), so implementations must return a new ByteBuffer or slice for each call.
