LEAD Theora Encoder

The LEAD Theora Encoder is a DirectShow encoder for compressing video data using Theora compression. Theora is an open video codec developed by the Xiph.org foundation aimed at offering a patent-free alternative to MPEG-4. The compression is comparable to MPEG-2, H.263, MPEG-4 and H.264 and, unlike these codecs, the Theora codec is free of patent fees.

For more information, you can go to http://www.xiph.org and http://theora.org.

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