hello Sir/madam,

I am using Dm6467t based EVM from spectrum digital. I have connected a CCD camera on composite input interface of board and component out at output  port.  I am getting following problem while runing encode example

Failed VIDIOC_S_FMT on /dev/video2 (Invalid argument)Failed VIDIOC_S_FMT on /dev/video2 (Invalid argument)
Error: Failed to create display device

I am not able able to run the encode demo. I have done following steps

    Good Morning TI community,

    Its a gr8 surprise that no body could see my post... not a single TI FAE could touch this. I am seriously in need. please help.

    In addition to problem mentioned in previous post, I would like to know the bootargs for DM6467t for capturing composite video input and component video output.

    kindly look into the post and help me to resolve the issues of DM6467t related board.

     

    lots of thanks in advance.

    Pradeep,

    Can you confirm whether /dev/video[n] is present in your file system?

    Also, as suggested to you, please try to build and run the display only sample application, with the  desired resolution changes, and see whether that works for you or not. In case it works, you can take the same changes to your custom app.

    Hi Pradeep,

     

    Log clearly tells that pitch you are trying to set is incorrect. Because of this, S_FMT ioctl is failing on the display driver. Can you please check what pitch you are trying to set? What the buffer size?

     

    Thx,

    Brijesh Jadav

    Dear Brijesh,

     

    thanks for replying. I tried to understand the pitch funda. What I understand, pitch means number of pixel in horizontal (hpitch). Its generally taken from video format setting. That I have defined in Display.c. I do not know how to set pitch manually. Where should I write the pitch information. Can u please tell me how to define the pitch in manually.

    thanks& regards
