The issue with providing ENUM_FMT support on MC-enabled drivers is that the media bus format has an effect to which pixel formats are available. What has been discussed in the past but what remains unimplemented is to add the media bus code to v4l2_fmtdesc for user to choose. That would allow meaningful ENUM_FMT support. For users such as libv4l2, i.e. code == 0 --- it should just tell the user what it can do with the active media bus format. -- Kind regards, Sakari Ailus e-mail: sakari.ailus@iki.fi XMPP: sailus@retiisi.org.uk
