In qcom driver s_fmt on capture queue will return bigger or the same as coded resolution depending on the width/height.

The the userspace can/must call g_crop to receive the active resolution for displaying. -- regards, Stan -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
