H.263 Codec SDK Libraries

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.
