The LEADTOOLS H.263 codec is a high-quality, lossy, inter-frame codec
with a quality and compression ratio comparable to MPEG-4. It can be used
by .NET (C# & VB) and C/C++ developers within a range of DirectShow
and Media Foundation applications, including video conferencing, creating
3GPP files (H.263 Video/AMR Audio) for playback on mobile phones, screen
capture, Internet video, and surveillance.
Rate control algorithm based on the TMN8 which is suitable for videophone applications
Encode UYVY, YUV2, YV12, I420, RGB24, and RGB32 formats
Decode RGB24, RGB32 YUY2, YV12, RGB555, and RGB565 formats
Implements all elements and functionality of ITU-T H.263, plus
Deblocking Filter Mode (Annex J)
Unrestricted Motion Vector (Annex D)
Advanced Intra Coding Mode (Annex I)
Advanced Prediction Mode (Annex F)
Modified Quantization Mode (Annex T)
Alternative Inter VLC Mode (Annex S)
Supports any video dimension
Employs half-pixel precision for motion compensation
Unrestricted motion vectors
Includes .NET (C# & VB) and C DLL libraries for 32 and 64-bit development
What is H.263?
H.263 is an ITU standard, designed for low bit rate communications such as video conferencing
and video telephony applications. It can be used for a wide range of simultaneous bit rates,
both high and low. H.263 is a hybrid of interframe compression that makes use of temporal
redundancy and intraframe transform coding to use spatial redundancy as a compression
advantage. Accordingly, a superior compression ratio can be achieved in comparison
to other video codecs.
