[Mesa-dev] [PATCH 09/12] st/va: add functions for VAAPI encode

Mon Jul 18 22:43:42 UTC 2016
Add necessary functions/changes for VAAPI encoding to buffer and picture. These changes will allow driver to handle all Vaapi encode related operations. This patch doesn't change the Vaapi decode behaviour.
