Subject: [PATCH 6/8] weston: Add EGL_YUV and EGL_SAMPLE attribs to use mali400
|
||
|
|
rendering nv21 surface
|
||
|
|
|
||
|
|
Add EGL_YUV_COLOR_SPACE_HINT_EXT and EGL_SAMPLE_RANGE_HINT_EXT attribs,
|
||
|
|
in order to compatible with mali400 ddk;
|
||
|
|
So this commit can use GPU composite nv21 surface in weston;
