VideoFrame.Buffer (Video Android 7.4.0)

All Superinterfaces:

RefCounted

All Known Subinterfaces:

VideoFrame.I420Buffer, VideoFrame.TextureBuffer

All Known Implementing Classes:

JavaI420Buffer, NV12Buffer, NV21Buffer, Rgba8888Buffer, TextureBufferImpl

Enclosing class:

VideoFrame
```
public static interface VideoFrame.Buffer
extends RefCounted
```
Implements image storage medium. Might be for example an OpenGL texture or a memory region containing I420-data.
Reference counting is needed since a video buffer can be shared between multiple VideoSinks, and the buffer needs to be returned to the VideoSource as soon as all references are gone.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`VideoFrame.Buffer`	`cropAndScale(int cropX, int cropY, int cropWidth, int cropHeight, int scaleWidth, int scaleHeight)`	Crops a region defined by \|cropx\|, \|cropY\|, \|cropWidth\| and \|cropHeight\|.
`int`	`getHeight()`
`int`	`getWidth()`	Resolution of the buffer in pixels.
`void`	`release()`	Decreases ref count by one.
`void`	`retain()`	Increases ref count by one.
`VideoFrame.I420Buffer`	`toI420()`	Returns a memory-backed frame in I420 format.

- Method Detail
  - getWidth
```
int getWidth()
```
    Resolution of the buffer in pixels.
  - getHeight
```
int getHeight()
```
  - toI420
```
VideoFrame.I420Buffer toI420()
```
    Returns a memory-backed frame in I420 format. If the pixel data is in another format, a conversion will take place. All implementations must provide a fallback to I420 for compatibility with e.g. the internal WebRTC software encoders.
  - retain
```
void retain()
```
    Description copied from interface: RefCounted
    
    Increases ref count by one.
    
    Specified by:
    
    retain in interface RefCounted
  - release
```
void release()
```
    Description copied from interface: RefCounted
    
    Decreases ref count by one. When the ref count reaches zero, resources related to the object will be freed.
    
    Specified by:
    
    release in interface RefCounted
  - cropAndScale
```
VideoFrame.Buffer cropAndScale(int cropX,
                               int cropY,
                               int cropWidth,
                               int cropHeight,
                               int scaleWidth,
                               int scaleHeight)
```
    Crops a region defined by |cropx|, |cropY|, |cropWidth| and |cropHeight|. Scales it to size |scaleWidth| x |scaleHeight|.
