After looking in our beloved (hated by others) Wikipedia, in the link http://en.wikipedia.org/wiki/AMD_Performance_Library, I found that the AMD contributed to an open source version of the library, based on Apache License v2. So, for ones that *need* of an open source code (or want to learns about CPU intrinsics) instead of free use but closed souce (APL) see and contribute to the project http://framewave.sourceforge.net.
I'll continue to port ptlib colours conversions and the h.323 video codecs to the APL version. After this I'll see if make the same to the Framewave version.
PS.: I'm working to made the video split of OpenMCU a little more managed, in a week or two I'll send the files ;)
