Subject: st/va: added internal storage for VAImage and BGRA format
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=05e225b558a330994cacad5d97f640cff86b4aff;p=mesa.git

st/va: added internal storage for VAImage and BGRA format

When calling vaCreateImage() an internal copy of VAImage is maintained
since the allocation of "image" may not be guaranteed to live long enough.
