Hi Hans,
It got stuck on this version. I have some slight improvements locally
but haven't sent them as there hasn't been any comment to this so far.
AFAIR Sakari had some doubts about handling multiple pipelines within
one media controller. In this approach only one pipeline is allowed.
There has to be a new IOCTL added for locking pipelines, to handle this
IIRC.
Sakari, is this ioctl really needed or something that can be added later?
Besides there are some v4l-utils build system dependency issues to
solve, I mentioned below in the cover letter.
If I remember correctly the libmediactl API may still change, which is
why it isn't in lib. So statically linking it isn't a bad idea at the
moment. Laurent, can you confirm this?
Is there anything else that blocks this patch series?
v4l-utils side issues:
I'd have to apply my local bug fixes and submit the next version.
Kernel side issues:
There is a regression in the kernel related to FIMC-LITE
and FIMC-IS-ISP entities. Effectively currently it is only possible
to setup pipelines with S5C73M3 sensor to fimc.0.capture and
fimc.1.capture entities.
I would also have to rebase the patches for exynos4-is driver
for avoiding failure on open when the device being opened
has no connected sensor.
