Re: [Gnash-dev] Flash HD (H.264) video decoding acceleration

Partial review of the VAAPI patch. I'm most concerned with what the patch does for maintainability. There are ever fewer developers with less and less time, and it's already difficult to maintain all the GUIs, media handlers, and renderers. So it's pretty crucial that new code doesn't add more

Hi Gwenole, First off, I have to express some concern that apparently only proprietary GPU drivers are supported for use with VA API -- at least, for the codecs that are commonly used in Flash videos. The last thing we want to do is encourage people to use proprietary drivers for use with Gnash.

I am not sure to fully understand what you mean but I will think again about it tomorrow or over this night. Isn't Gnash/Flash limited to VP6 and H.264? How would MPEG-2 MoComp/iDCT support help Gnash? All existing video codecs (except Dirac) work basically the same way. They use the same
