Why this is so big no no from Sony AND Asus?
People who doesn't understand how important this feature is, please don't reply on this. We need real answers.
Asus, what you can do for this is (as a big customer): Please push and demand that Sony put those drivers and API calls available for 3rd developers!
Also, if Asus really want that everyone is pleased Asus camera app. Add those advanced features from open camera to it (heck try hire its developer to Asus). Especially bitrate options. Advanced users need more control their own footage.
