These are all trivial to merge. * commit '92fdea37477b5a2d1329e5ef0773e24473fa8f12': vaapi_h265: Add -qp option, use it to replace use of -global_quality vaapi_h265: Add constant-bitrate encode support vaapi_h264: Add encode quality option (for quality-speed tradeoff) vaapi_h264: Add -qp option, use it to replace use of -global_quality vaapi_encode: Add support for codec-local options vaapi_h264: Add constant-bitrate encode support vaapi_encode: Refactor slightly to allow easier setting of global options Merged-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
