MPEG4 SP Encoder


Tatvik’s MPEG-4 Simple Profile Video Encoder implementation is one of the fastest implementations of MPEG-4 SP Encoder for Mobile Platforms. The implementation is highly efficient in terms of low MIPS reqiorement and small memory footprint. Tatvik has developed the encoder for low-power and high efficiency mobile applications. Tatvik MPEG-4 encoder creates high quality streams at low bit-rates.
