H.264 BP Video
Encoder
Tatvik’s H.264 Baseline Profile Video Encoder implementation is one of the fastest implementations of H.264
Encoder for Mobile and PC Platforms. The implementation is highly efficient in terms of low MIPS and small memory footprint. The encoder has four speed modes which provide best quality for available processing
power.
