< this is a fragment of the encoded frame
< alias for struct vpx_fixed_buf
< alias for struct vpx_rational
< The frame partitions are independently decodable by the bool decoder, meaning that partitions can be decoded even though earlier partitions have been lost. Note that intra predicition is still done over the partition boundary.
< alias for struct vpx_codec_enc_cfg
< deadline parameter analogous to * VPx BEST QUALITY mode.
< Can issue PSNR packets
< Calculate PSNR on each frame
< deadline parameter analogous to * VPx GOOD QUALITY mode.
< deadline parameter analogous to * VPx REALTIME mode.
< Improve resiliency against losses of whole frames
< frame is the start of a GOP
< frame should be decoded but will not be shown
< frame can be dropped without affecting the stream (no future frame depends on this one)
