hi,
please observe these images, in this images some noise is there.
can you please tell me,why blur images are coming from my analog camera ?
and can you please tell me is it hardware issue or my driver issue ?
Thanks&Regards
Venkatesh
Where did you get this sample ADV7180 driver?
Best Regards,
Artur
in ltib/rpm/Build/linux2.6/drivers/media/mxc/video/capture/...
Best Regards

The sample v4l2 driver you've mentioned only manages the parallel CSI interface module, but does not handle the setup of the ADV7180 chip itself. Have you performed the ADV7180 chip configuration/setup correctly? Please check. Also, please check with the oscilloscope the ADV7180 chip's output signal timings. Are they all correct?
Best Regards,
Artur
i am using adv7180 driver as a reference
modprobe adv7180_camera
modprobe mxc_v4l2_capture
cd /unit_tests
lucid@lucid-desktop:/unit_tests$ ./mxc_v4l2_tvin.out -ot 0 -ol 10 -ow 720 -oh 480 -m 2
problem is iam getting blur video,can you please tell me why like this it is coming?
Thanks Yuri,
i am getting this error

$ gst-inspect

Do you mean the i.MX53 QuickStart Board (QSB)? If so, this board does not have a dedicated connector for camera connection. All of the CSI0 interface signals are routed to the J13 expansion connctor, please refer to the board's schematic, available on the i.MX53 QSB Downloads web page (chek under the "Printed Circuit Boards and Schematics-Schematics" tab):
http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=IMX53QSB&fpsp=1&tab=Design_Tools_Tab
There is no dedicated camera module for this connector, so, first, you have to build the camera hardware. Then, the Linux BSP provides a prototype camera driver that you have to modify according to the camera you use.
Or, you can use an USB camera that supports the UVC specification:

Have a great day,
Artur

Thanks artur
I built the camera hardware and i am using the on of the prototype camera driver. but how can i test the camera video in my module and how can i know if it is capture or not.
You may use the Gstreamer to test the cam.
$ gst-launch v4l2src ! mfw_v4lsink
if doesn't work, please try:
$ gst-launch v4l2src ! decodebin2 ! mfw_v4lsink
To install Gstreamer parsers under Ubuntu :
$ sudo apt-get install gstreamer0.10-plugins-good && sudo apt-get install gstreamer0.10-plugins-bad
