История версий и изменений программы VP6
6.1.0.2 (01.01.1970)
· Achieves a 10-15% improvement over VP6 beta.
· Now supports Multi-pass encoding.
· Highly configurable (constant or variable) datarate control.
· Direct access to the reconstruction buffer.
· Improves Error recovery.
· Multiple platform support (Intel, Equator, TI, PowerPC).
· Compresses high-definition (HD) material with no restrictions on the encoder. VP6 can play back 1920x1080 HD material on a 2.5 GHz PC and 1280x720 material on a 1.5 GHz PC.
· Supports real-time encoding at full D1 resolution.
· Up to 40% image quality improvement over VP5.
· Up to 50% faster playback than VP5.
· Optimized to produce the best quality video available on high-resolution material (640x480 and higher).
· Designed for inexpensive DSP processors. VP6 is ideal for embedded chipsets in non-PC devices and set-top boxes. Unlike some standards-based codecs (JVT, MPEG-4 v10), VP6 runs on general-purpose DSPs without requiring expensive add-on subprocessors.
· VP6 is a purely software-based solution that can be upgraded easily.
· Introduces predefined "profiles": Simple for fast playback on inexpensive processors, General for full D1 on set-top boxes, and Advanced for ensuring the best quality possible at extremely low datarates.
· Achieves any requested data rate by choosing automatically to adjust quantization levels, adjust encoded frame dimensions, or drop frames altogether.
· Carries no burdensome "patent pooling" restrictions or complicated external licensing fees.
