Detailed Description
Decoded YUV/RGB frame in FFMpeg format.
- This FrameClass has decoded video, and is used by the VideoDecoder class. AVThread passes this frame down the filterchain.
- It's up to the VideoDecoder to call AVBitmapFrame::update() and to update the helper objects (AVBitmapFrame::bmpars, etc.)
- Constructor does not reserve data for frames. This is done by classes using this class, for example by VideoDecoder. This is desirable as we don't know the bitmap dimensions yet ..
This is an "intermediate frame". It is typically copied asap into a YUVFrame.
Copiable/Queable : no
