Interesting, but I don't see how one could create a complete implementation without a spec for the Sorensen Spark codec.

- wmf 17y agoSorenson Spark == H.263 (not a typo), which is documented. The problem with Flash is VP6, although FFMPEG reverse engineered it.
- vetinari 17y agoActually, it is based on a draft h.263, not the final h.263. One of the older flash specification did document it. The svq3 specification was removed from swf specs around time it was made available under more liberal license (Sorenson probably didn't agree with wider specs availability).
- kierank 17y agoFFmpeg has reverse engineered it and there is an open source decoder and some documentation.
