LEAD H263 Encoder (2.0)

The LEAD H263 Encoder (2.0) is a DirectShow encoder for compressing video data using the H.263 standard. The H.263 video compression can be used in a wide range of applications such as desktop videoconferencing, internet video, surveillance and monitoring, transmission over a low bit-rate (down to 9600bps), radio links, and media storage. The compressed video data can be stored inside AVI, Ogg or 3GPP files (with or without audio).

The compression options for the LEAD H263 Encoder can be set manually through the encoder property page. They can also be set programmatically through the ILMH263Encoder interface.

The maximum video size for H263 compression is 2048x1152.
