Auto-adaptive encoder frame resizing logic Note: This feature is still in development. Add an option for the encoder to decide the resolution at which to encode each frame. Each KF/GF/ARF goup is tested to see if it would be better encoded at a lower resolution. At present, each KF/GF/ARF is coded first at full-size and if the coded size exceeds a threshold (twice target data rate) at the maximum active Q then the entire group is encoded at lower resolution. This feature is enabled in vpxenc by setting: --resize-allowed=1 In addition, if the vpxenc command line also specifies valid frame dimensions using: --resize-width=XXXX & --resize_height=YYYY then *all* frames will be encoded at this resolution.
