H.263

Overview

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.

Features

  • Picture formats: YUV420, YUV422, YUV444, YUV410, YUV411, RGB24, BGR24, RGB32, Grayscale8, RGB565, RGB555.
  • Standard picture sizes: SQCIF (128x96), QCIF (176x144), CIF (352x288) and 4CIF (704x576).
  • SPIRIT H.263 codec is compliant with the ITU-T H.263 standard: H.263 Baseline, Annex D, Annex E, Annex F, Annex J, Annex I, Annex K, Annex S, Annex T
  • Grayscale coding mode is available.
  • Up to half pixel precision for motion compensation.
  • RTP packet generation and decoding of RTP packet flow are supported.
  • Unbroken bitstream, packetized bitstream, and framed bitstream modes are supported.
  • Timing support for easy video/audio synchronization.
  • Accurate bit rate control.
