| static VideoFrame.Buffer | cropAndScaleI420 (final I420Buffer buffer, int cropX, int cropY, int cropWidth, int cropHeight, int scaleWidth, int scaleHeight) |
Implementation of VideoFrame.I420Buffer backed by Java direct byte buffers.
|
static |
Wraps existing ByteBuffers into JavaI420Buffer object without copying the contents.
| width | width. |
| height | height. |
| dataY | direct buffer, not allowed to be null, otherwise exception will throw. |
| strideY | stride y. |
| dataU | direct buffer, not allowed to be null, otherwise exception will throw. |
| strideU | stride u. |
| dataV | direct buffer, not allowed to be null, otherwise exception will throw. |
| strideV | stride v. |
| releaseCallback | nullable, invoked the this buffer released. |
|
static |
Allocates an empty I420Buffer suitable for an image of the given dimensions.
| width | width. |
| height | height. |

| int io.agora.base.JavaI420Buffer.getHeight | ( | ) |
| ByteBuffer io.agora.base.JavaI420Buffer.getDataY | ( | ) |
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.
Implements io.agora.base.VideoFrame.I420Buffer.
| ByteBuffer io.agora.base.JavaI420Buffer.getDataU | ( | ) |
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.
Implements io.agora.base.VideoFrame.I420Buffer.
| ByteBuffer io.agora.base.JavaI420Buffer.getDataV | ( | ) |
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.
Implements io.agora.base.VideoFrame.I420Buffer.
| I420Buffer io.agora.base.JavaI420Buffer.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.
Implements io.agora.base.VideoFrame.Buffer.
| void io.agora.base.JavaI420Buffer.retain | ( | ) |
Increases ref count by one.
Implements io.agora.base.VideoFrame.Buffer.
| void io.agora.base.JavaI420Buffer.release | ( | ) |
Decreases ref count by one. When the ref count reaches zero, resources related to the object will be freed.
Implements io.agora.base.VideoFrame.Buffer.

| 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|.
Implements io.agora.base.VideoFrame.Buffer.
| VideoFrame.Buffer io.agora.base.JavaI420Buffer.mirror | ( | int | frameRotation | ) |
Apply mirror
Implements io.agora.base.VideoFrame.Buffer.
| VideoFrame.Buffer io.agora.base.JavaI420Buffer.rotate | ( | int | frameRotation | ) |

Implements io.agora.base.VideoFrame.Buffer.
|
static |
Crops a region defined by |cropx|, |cropY|, |cropWidth| and |cropHeight|. Scales it to size |scaleWidth| x |scaleHeight|.
