+Subject: [PATCH] libstagefright: Enable meta mode for 7x27a video encoder
+
+msm7627a family of chipsets supports only one input frame at
+one time. camera expects the input frame to be released before
+sending another frame. so send one input buffer and available
+output bufefrs to video encoder component. Release the input
+buffer to camera (to get another frame) after receiving input
+frame done callback from video encoder component.
