H.263 is a video compression standard originally designed as a low-bitrate compressed format for videoconferencing.

H.263 is a video compression standard originally designed as a low-bitrate compressed format for videoconferencing. It was developed by the ITU-T Video Coding Experts Group (VCEG) in a project ending in 1995/1996 as one member of the H.26x family of video coding standards in the domain of the ITU-T.

H.263 has since found many applications on the internet: much Flash Video content (as used on sites such as YouTube, Google Video, MySpace, etc.) used to be encoded in Sorenson Spark format (an incomplete implementation of H.263[1][2][3]), though many sites now use VP6 or H.264 encoding. The original version of the RealVideo codec was based on H.263 up until the release of RealVideo 8

How to packetize H.263 into RTP packets after stream is encoded with FFMPEG

I have a Java based VoIP Softphone (jPhoneLite) that supports H.263+ and H.264. But currently the H.263 (RFC2190) is incomplete. According to the RFC the data must be split up at MB (macroblock?) boundaries but I have no idea how to find them. If…

Video codec: dealing with delta values

Assume I have a ref (key) frame I encoded. Now I want to inter-predict the next frame called delta frame P. To do that I calculate motion vectors and find diff between compensated P and I. However, this diff can be quite huge in some cases. Given…
