From: Julien Isorce Date: Fri, 30 Oct 2015 11:42:52 +0000 (+0000) Subject: st/va: implement VaDeriveImage X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=802ba6f8655bf967299b027204ecdd5855050609;p=mesa.git st/va: implement VaDeriveImage And apply relatives change to: vlVaBufferSetNumElements vlVaCreateBuffer vlVaMapBuffer vlVaUnmapBuffer vlVaDestroyBuffer vlVaPutImage It is unfortunate that there is no proper va buffer type and struct for this. Only possible to use VAImageBufferType which is normally used for normal user data array. On of the consequences is that it is only possible VaDeriveImage is only useful on surfaces backed with contiguous planes.
