Excellent! Thanks for working on this and sharing it. It looks like you have rewritten the plugin more or less from scratch, is that right? A wise move... I see you have already included our recent fix for the Xv plugin too, nice. The IPP deinterlace flag handling is not present, I guess you have excluded that for good reason, I'm not even sure what it does... Also looks great that you have got the xv plugin using vmeta libs to allocate physical memory areas. Rather than facing the libbmm/libphycontmem mess directly like the previous version did. > The decoder should be stable.

The new driver source is available on the dri-devel mailing list. However there are several complications that must be solved before it goes upstream. Then a new X driver will be needed, and whoever steps up to maintain that will have to decide if they really want to support the horrible hack used by the vmetaxv plugin. And then implement it, test it, etc. Then there will be a few other hurdles to go over before the new drivers are really a convincing replacement. Like GPU support. In other words, I don't see this being upstream soon, and even when that does happen, there will probably be other major steps required before it is really useful. So I would continue to focus on the existing "stack". cheers Daniel _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
