I'm open to send a v2 based out your feedback. I was prompted to write this patch when writing a test for vin-tests for TB/BT and I had to look in the yavta sources to find which strings yavta used for the different field options and misinterpreting the help for --field to only concern interlaced field formats. As you state yavta is a low-level tool so I'm fine with the patch as is just to demonstrate that the --field argument takes a value and is not exclusive to interlaced formats or extend it similar to '--format help'. > > > > printf(" --log-status Log device status\n"); > > > printf(" --no-query Don't query capabilities on open\n"); > > > printf(" --offset User pointer buffer offset from page start\n"); > > -- > Regards, > > Laurent Pinchart -- Regards, Niklas Söderlund
