The goal of this series is to let userland applications enumerate all the supported pixels formats of a stateless decoder without setting all the possible codec-dependent control. That offer a simplest solution for applications to discover supported pixels formats and possibly let them doing smarter choice between stateless decoders. changes in version 2: - Clarify documentation. - Only keep V4L2_FMT_FLAG_ALL_FORMATS flag in ioctl.
