Message-ID: <4EB39F9F.9080305@cisco.com> (raw)
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
