Detailed Description
A GPU YUV frame.
The payload is at the GPU. YUVFrame instances are constructed/destructed by the OpenGLThread.
- Resources on the GPU (target pointers for data upload, OpenGL indexes). YUVFrame::bmpars describing those resources
- YUVFrame::source_bmpars describing the frame dimensions (should be less than equal to YUVFrame::bmpars)
- No helper objects need to be updated .. data is imply copied and overwritten when calling YUVFrame::fromAVBitmapFrame
Copiable/Queable : no
Instances of this frame are not copiable when crossing thread borders, however, instances of this frame are used internally by OpenGLThread and OpenGLFrameFifo, and they are being queued and recycled.
For more details, see OpenGLFrameFifo and OpenGLFrameFifo::prepareAVBitmapFrame
