Hi, Teemu
Your proposal is our target in the future.
The mfldv4l2camsrc which is derived from gst-nokia-videosrc only supports the
Intel MFLD platform camera system.
In the beginning, I decided to add the mfldcamsrc to gst-nokia-videosrc and
created another element for Intel MFLD camera. But the maintainer think it will
be better to create a separated repository to keep the code clean. That's why I
created a separated repository for mfldv4l2camsrc.
We planned to support the camerabin and qt-mobility.
It is OK if the mfldcamsrc can be one of the element of gst-plugins-camera.
This is also our upstream goal.
As there is no useful camera source element in Meego to support the camerabin,
so I decide to add the mfldcamsrc to support camerabin. The middle ware team
and our customer also need this source element. That's why I need to add it to
the Meego build.
Thanks.

good point, they will surely differ. And I surely hope it stays on gst
level as you refer.
However, Meego tends to generalize packetizing as far as possible and
also gst-plugins packaging tend to gather stuff. So, I had a feeling the
camera stuff is not an exception.
If we consider...
qt-mobility (camera API, multimedia/gstreamer/camerabin)
gstreamer
gst-plugins-bad-free (camerabin, libphotography)
gst-plugins-camera (generic source elements and other oss source
elements for different hw)
kernel
And when the request comes to use specific implementation - it would
mean additional packages, not replacive. Doesn't that look good ?
Although deve's are not having fun with this ideology in Meego, I felt
it isn't far from possible if we get humble and sync up to iterate
things for camera features. And yet, man could enable all features using
HW specific replacive solution.
In mean time, we will likely push another specific package basing on
gst-nokia-videosrc and try to enable ways of utilizing it through higher
level API's as planned. Unfortunately from my point of view it requires
a bit of studying and takes some time. During this workout I have also
got a bit diverged input about how things are implemented within
top-level components, so its time to read the code myself. However, I'm
all ears to anyone working with the field.

Just a quick note highlighting the obvious: the camera source component in
GStreamer and the subdev drivers are a part of camera HW adaptation. So they
may (and likely will) differ between different HW platforms.

Hi,
The source of gst-v4l2-camsrc project in OBS is located at
http://meego.gitorious.org/maemo-multimedia/mfldv4l2camsrc which is
branched from gst-nokia-videosrc. Intel engineers are working on this
project to do more enhancements/fixings for Intel Medfield ISP.
Also cc'd hu, gang for more technical details.
Thanks

Subject: [MeeGo-dev] camera subdev solution ?
Hello,
I've been working with camera stack for Meego/N900. Recently the
gst-v4l2-camsrc was added to meego obs and I was a little confused
about
the naming and different affiliations of the project.
However, I assume kind of generalization is about to happen with v4l2
subdev& mediacontroller api's, but I would be delighted if someone
could sync me up to the work and roadmap of previously committed
projects.
I have build modified gst-nokia-videosrc project in my obs home
(home:teemu.tuominen) for Meego/N900 to gain raw viewfinder mode
through
gst components (camerabin, subdevsrc). Is gst-v4l2-camsrc now the place
to add such patches ?

Teemu Tuominen
