[maemo-developers] V4L2 and Gstreamer

[From: Shu Shi]

Hi everyone,

I am working on a N800/OS2008 application which captures and video and
analyzes the content. I need to write or re-use some codes to capture
the video through camera. According to the documentation, it says that
V4L2 is supported in kernel but the whole system is based on Gstreamer
framework. I also tried some open source software using V4L/V4L2 to
control camera, such as opencv, spcaview, but all failed.

My questions are:
1. Can I use V4L2 interface to control camera directly in N800/OS2008?
Or everything is controled by Gstreamer?
2. If V4L2 can be used, is there anything special in this platform I
need to pay attention to?
3. If everything is controlled by Gstreamer, is there any sample codes
to control camera I could reference?

Many thanks!

Best,
Shu
