CVBS Video Loopback on DM3730 - Kernel 2.6.37

Hi,

I am working on DM3730 Mistral EVM.
I am trying to run the video loopback application from composite input(CVBS) to LCD output.
I am using DVSDK_4306 - Linux 2.6.37

For this, I am running the following application from the filesystem:
/usr/share/ti/ti-dmai-apps/video_loopback_copy_dm3730.x470MV -O lcd -I composite

When I run this application, I see the following error messages:
Capture: Current Input: camera
VIDIOC_S_INPUT: Invalid argument
Capture: Input changed to: camera
VIDIOC_ENUMSTD: Invalid argument
VIDIOC_ENUMSTD: Invalid argument
VIDIOC_ENUMSTD: Invalid argument
VIDIOC_ENUMSTD: Invalid argument
VIDIOC_ENUMSTD: Invalid argument
VIDIOC_ENUMSTD: Invalid argument
VIDIOC_ENUMSTD: Invalid argument
VIDIOC_ENUMSTD: Invalid argument
VIDIOC_ENUMSTD: Invalid argument
.
.
.

Please find the complete boot message below:

    Hi Bharath,

    I read in the last rows in your description that the demo works fine with the previous dvsdk (4.02.06) therefore I compare the sources of video_loopback_copy in both dvsdk version and I discover that there are no differences. Have you made some changes in the source code?

    Hi Tsvetolin Shulev,

    Thanks for your fast response.

    I have not made any changes in the source code of the both.

    Hi Bharath,

    Could you make the following tests:

    1. Try to start video_loopback_copy from dvsdk-4.02 under dvsdk-4.03

    2. Try to start video_loopback_copy from dvsdk-4.03 under dvsdk-4.02

    Share the results please.

    Hi Tsvetolin Shulev,

    Please find the results of the above mentioned tests:
    1. starting video_loopback_copy from dvsdk-4.02 under dvsdk-4.03:
    root@dm37x-evm:/usr/share/ti/ti-dmai-apps# /usr/share/ti/ti-dmai-apps/video_loopback_copy_dm3730.x470MV -O lcd -I composite
    Failed to detect capture video standard

    2. starting video_loopback_copy from dvsdk-4.03 under dvsdk-4.02:
    root@dm37x-evm:/usr/share/ti/ti-dmai-apps# /usr/share/ti/ti-dmai-apps/video_loopback_copy_dm3730.x470MV -O lcd -I composite
    Failed to detect capture video standard

    As we can see, getting the same error message on both.

    Can you please explain me why there are only 3 video nodes in kernel 2.6.32 whereas kernel 2.6.37 has 9 video nodes under /dev?
    Also what does v4l-subdev0-8 device nodes represent? I cannot see these nodes in Kernel 2.6.32.
    The kernel 2.6.32 is having omap34xxcam.c and omap34xxcam.h camera driver files. However, in the Kernel 2.6.37 the omap34xxcam.c/omap34xxcam.h files are not
    available.
    How does the camera and V4L2 framework differ from 2.6.32 and 2.6.37?

    Bharath S
