<p class="" style="margin-bottom:12pt"><span lang="EN-US">Hi got a question:
<br>
<br>
I noticed that the #define values for for VAConfigAttribRTFormat in VAConfigAttrib does not include BGRA or ARGB formats (it does RGB 16 and RGB32), but the VASurfaceAttrib's VASurfaceAttribPixelFormat does allow it thru a four_cc value. Does that mean I can't
decode the H.264 bitstream data directly to a BGRA surface, I have to convert explicitly?
