VideoFrame.Buffer | cropAndScale (int cropX, int cropY, int cropWidth, int cropHeight, int scaleWidth, int scaleHeight) |
Android texture buffer backed by a SurfaceTextureHelper's texture. The buffer calls |releaseCallback| when it is released.
Matrix io.agora.rtc.gl.TextureBufferImpl.getTransformMatrix | ( | ) |
Retrieve the transform matrix associated with the frame. This transform matrix maps 2D homogeneous coordinates of the form (s, t, 1) with s and t in the inclusive range [0, 1] to the coordinate that should be used to sample that location from the buffer.
Implements io.agora.rtc.gl.VideoFrame.TextureBuffer.
int io.agora.rtc.gl.TextureBufferImpl.getWidth | ( | ) |
Resolution of the buffer in pixels.
Implements io.agora.rtc.gl.VideoFrame.Buffer.
VideoFrame.I420Buffer io.agora.rtc.gl.TextureBufferImpl.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.
void io.agora.rtc.gl.TextureBufferImpl.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.
VideoFrame.Buffer io.agora.rtc.gl.TextureBufferImpl.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.
