Member Function Documentation

◆ getWidth()

int io.agora.rtc.gl.RgbaBuffer.getWidth ( )

Resolution of the buffer in pixels.

Implements io.agora.rtc.gl.VideoFrame.Buffer.

◆ toI420()

VideoFrame.I420Buffer io.agora.rtc.gl.RgbaBuffer.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.rtc.gl.VideoFrame.Buffer.

◆ retain()

void io.agora.rtc.gl.RgbaBuffer.retain ( )

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.

Implements io.agora.rtc.gl.VideoFrame.Buffer.

◆ cropAndScale()

VideoFrame.Buffer io.agora.rtc.gl.RgbaBuffer.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|.

Implements io.agora.rtc.gl.VideoFrame.Buffer.
