H.263, H.263+, H.263++
SPIRIT H.263 codec provides high quality video encoding and decoding for real-time video transmission applications. The codec preserves good picture quality both at high and low bit rates.SPIRIT H.263 is deeply optimized for real-time image compression on PC and ARM platforms and can be ported to other platforms. The codec performance depends on input sequence features and compression parameters. For example, the performance does not exceed 10% CPU usage for simultaneous QCIF encoding and decoding at 30 fps (talking head with static background) on a 3 GHz CPU
