The series also enhance the format enumeration of v4l2 subdevices. Further more it extends the cam utility to demonstrate the usage of how formats can examined and validated. One shortcoming of this series is that it only extends the uvcvideo pipeline with code to gather format information and perform validation. This however do not impact other existing pipeline handlers as they keep functioning as before this series. That is no format information can be retrieved and format validation is still supported all yet as simple as before this series.
