SPIRIT H.264 codec implements the H.264 (baseline) video compression standard. It provides high-quality video encoding and decoding for real-time video transmission applications. SPIRIT H.264 supports a wide range of data rates. The codec preserves good picture quality both at high and low bit rates. SPIRIT H.264 is deeply optimized for real-time image compression on PC and ARM platforms and can be ported to other platforms. SPIRIT H.264 provides real-time encoding of 4CIF on a 2 GHz CPU.
