h263-rs

h263-rs is a pure-Rust implementation of ITU-T Recommendation H.263 (2005/08), a video codec commonly used in early VoIP telephony and multimedia systems including Sorenson Spark and Adobe Flash Player. It is used primarily in Ruffle to provide H.263 video decoding capability.

Project status

h263-rs correctly decodes most Sorenson-flavor video streams. No attempt has yet been made to test other flavors of H.263, or any of the additional features in later versions of H.263.

There is currently no support for encoding H.263 video of any flavor.

Using h263-rs

Currently, this only ships as a library, which must be integrated in another project to play video.

Building from source

Structure

• h263 contains the core codec library
• yuv contains BT.601 YUV colorspace conversions needed for decoding H.263 video
