Hi,
VIDIOC_ENUMINPUT may set the flag V4L2_IN_ST_NO_SYNC in the status 
field. The flag is described in the documentation under "Digital Video" 
as "No synchronization lock" 
(http://hverkuil.home.xs4all.nl/spec/media.html#vidioc-enuminput). What 
kind of sync lock does it refer to? Horizontal sync lock? Vertical sync 
lock? Both? Tuner locked on signal? Something else? A few lines above is 
V4L2_IN_ST_NO_H_LOCK described under "Analog Video" as "No horizontal 
sync lock". Is V4L2_IN_ST_NO_SYNC the same as V4L2_IN_ST_NO_H_LOCK, but 
for digital video? Anyone who knows?

Regards,
         Mats Randgaard
