From: Hans Verkuil <hans.verk...@cisco.com>
These two patches have been sitting in my tree for some time. I'm posting these
just to get some discussion started.
The first patch adds new extended streaming ioctls that fix y2038 and that
simplify
the single/multiplanar handling which is very hard on userspace at the moment.
Note
that I dropped support for the timecode here as well, it's not used by any
driver
other than the 'virtual' drivers.
The second fixes y2038 for the DQEVENT ioctl.
It's very preliminary and there is no documentation yet.
Regards,
Hans
