Video capture utility

Other Parts Discussed in Thread: OMAP3530

Hi all,

I have found the simple video capture utility in t3530-linux/utilities/capture in the path. In this example, the usage menu containing the following options,

-d | --device name Video device name [/dev/video]
-h | --help Print this message
-m | --mmap Use memory mapped buffers
-r | --read Use read() calls
-o | --output Capture to file [file].

Please mention how to run the sample application in my board (CM-T3530). Also i want to know the /dev/video device  and capture file purpose. My assumption is,  the video device for displaying the image and capture file for capturing the image. Also which device i want to use for capturing the image. kindly send me the information.

Thanks

    Hi Samuthira,

    Could you give more details about which software release you are using?

    Hi Tsvetolin Shulev I am using OMAP3530 Processor module. The Kernel version is 3.0.68. I will tell my hardware configuration. The sensor (Sony ICX659ALA) is connected to the AFE ( Analog Front End) chip. We are using FPGA for generating the HSYNC, VSYC and PXL_CLK for getting the inputs from image sensor. The FPGA is continuously reading the frames from the sensor after power on the unit. The captured analog signals are converted to Digital signal by AFE chip. Finally the digital signal is given to the ISP data lines. I am using ISP CCDC. Now how can i read the data from CCDC memory. kindly give me the idea to read the data from CCDC memory. I checked in OMAP35x Technical Manual for configuration for CCDC. In this manual i have seen CCDC_SDA_ADDR register for configuring the address. but i don't know the address ranges of the OMAP3530 Processor module. so kindly update me the information. Thanks.
