Hi,

I add TVP5147 driver onti8148evm, I modified the test demo sLoopback through S-VIDEO. But It will lead to kernel crack.

So I think I couldn't use the sLoopback demo. Or maybe my driver have some errors.

What material or demo I can  refer to for test tvp5147 ? 

 

THANKS

    Hi,

    Please refer to the following appnote on how to add external decoders. Crash is not seen in decoder or v4l2 capture so I think something else is goofed up.

    Hi HardikShah,

    Thanks for your reply,

    Now,  tvp5147  work through VIP1 PortB, use the demo saLoopBackFbdev, But when creat capture there is a error -- "creat handle is NULL".

    VPSS_CAPTURE: create capture3
    VPSS_SHRBUF: FOUND 0xbfb14000, end 0xbfd00000, map vir 0xdcc14000 size 4096
    VPSS_FVID2: Fvid2 handle 0x00000000 with notifyno 13 within 0 ms
    VPSS_FVID2: create handle is NULL

    ti81xxvin ti81xxvin: Vps create failed

    The tvp5147 reg R/W  ok. Could you give me some suggestions about this issue.

    Thanks.

    Hi,

    This can happen in case parameters passed to FVID2_create are not proper. Can you please check those parameters and paste it here so that we can see which parameters is going wrong.

    Hi,

    Thanks for you suggestion, I reset the parameters and the capture can work now.

    I use the demo "saLoopBackFbdev", through CVBS input, but  the image lose color with wrong resolution.

    I check the parameter.

     1. in app

         pixelformat=V4L2_PIX_FMT_UYVY

     2.  in struct hdvpss_capture_sdev_info[] about the tvp5147 config setting.

        .video_if_mode = VPS_CAPT_VIDEO_IF_MODE_8BIT,

        .input_data_format = FVID2_DF_YUV422I_UYVY,

    3. Set tvp514_dev

       .current_std = STD_PAL_BDGHIN,

    So I don't know where I should check, the app or vpss configuration or tvp5147 reg setting.

    Hi,

    It seems your buffer pitch and width are not correct. Print bytesperline in S_FMT and see if its correct.

    Hi Hardik ,

    I am having an issue with 8-bit bt.656 capture on VIP2 PORTB using OMX application . My app has got only capture (VFCC ) component ,it captures the bt.656 data and stores into a yuv file . bt.656 8-bit capture on VIP1 PORTA works fine without any problems .

    I am using EZSDK 5.04 and working on a DM8148 custom board . we have got an FPGA feeding the bt.656 data to the DM8148 on our custom board .

    The problem is that OMX VFCC is not capturing frames on VIP2 PORTB ,I can see that input video is getting detected in VIP parser ( 0x48105a70 = 02D00120) ,this rules out the Pin muxing issue .

    I have tried capturing 8-bit bt.656 data on both VIP1 PORTB and VIP2 PORTB , Can you tell me what could be the problem ? we have got hdvpss sources ,I can modify the firmware if there are any firmware changes for the PORTB issue .

    Please see the below link for the post that I have started regarding PORTB issue using OMX application .

    Hi Sivaramkrishna,

    Thank for you help. But I'm not using OpenMAX for my application.
    I used the prebuilt firmware in EZSDK (dm814x_hdvpss_v4l2.xem3), so it's hard to figure out what happened on M3 core.

    Hi,

    I am not getting the question fully. If you have already got HDVPSS sources you can try running HDVPSS application on VS board where it shows the VIP1 and VIP2 both portB capture. You can see the create time values in that application and make sure that you are passing same values in your application. I am not much aware of OMX. But i dont think OMX supports 8-bit capture without change in M3 binary.

    Hi Hardik ,

    We already got chains application working for bt.656 capture on VIP2 PORTB on our custom board . I tried passing the same parameters in my OMX application but the OMX VFCC component is not capturing any frames .

    I am able to capture bt.656 8-bit data on VIP1 PORTA using OMX application ,which means there is some problem with bt.656 8-bit  capture on PORTB in the OMX framework . Can you please look into the issue ?  Please forward this query to the concerned TI expert  if you are not aware of OMX  .

    Please see the below link for the post that i have started regarding bt.656 8-bit capture on PORTB .

    Hi VVT,

    Can you post your working v4l2  code for capture on VIP1 PORTB ? I can see that you are able to capture using TVP5147 on VIP1 PORTB but got some issues . I will try out at my end and see if i can capture on my board .

    Thanks .

    Hi  Sivaramkrishna Neeruganti,


    Thank for your response.

    I'm using EVM8148(Mistral) and EZSDK5.5.1.4.

    My task is geting video input from Composite Video TVP5147, this video decoder is connected to VIP1 PORTB.
    Referring to this patch, I modified kernel and ti81xxvin in Linux PSP package (drivers/media/video/ti81xx).
    But I got a problem with HDVPSS after all.

    Hi,

    I reset the parameters by changing capture configration"VIP1 Port B"  to "VIP1 Port A", and my "handle 0" issue had been solved.

    Hi Sunny,

    Can you please answer the below questions ?

    Were you able to get the capture handle for VIP1 PORTB capture ?

    if you have got the handle for VIP1 PORTB ,were you able to capture frames on VIP1 PORTB ?

    Thanks .

    Hi Sunny Li,

    I changed capture configuration from VIP1 PortB to VIP1 PortA, but it didn't work.
    I did the following steps to change the capture configuration

    In \arch\arm\mach-omap2\ti81xx_vpss.c
    1. Use VPS_VIP_CTRL_CHAN_SEL_7_0 for ti81xxvin_subdev_info of TVP5147
    2. Change .inst_config[2] of static struct ti81xxvin_config ti81xx_hsvpss_capture_cfg

    Maybe I did something wrong. Can you show me how you change capture configuration?

    Hi,

    I can't get the handle for VIP1_PORTB capture.

    I get frame by setting capture parameter VIP1 PORTA.

    If you look in drivers/video/ti81xx/vpss/capt.c in the capture_create() function, you'll see a switch() statement that determines which VIP and PORT to use for the input. For the input, you have vidoe0, video4, video5, vidoe6. These equate to VIP0_PORTA, VIP0_PORTB, VIP1_PORTA, and VIP_PORTB here. So you want to use video5 instead of video6 to ensure that you use VIP1_PORTA which should get you past the "create handle is NULL" error message.

    I've got a custom board that has both the TVP70025 and TVP5151 for HD and SD video. Once I get past this error, I'm getting errors from videobuf_dqbuf when called from the saLoopBack application..

    Not sure how to get past that error yet.

    Hi,

    You may get error first time you start the capture. You need to stop and start the capture again. What error are you getting from DQBUF?I am talking about overflow error.

    We are getting an error "-512" from the videobuf_deqeue() function. Is that the expected error and does a restart fix it? I think I've tried restarting the application a couple of times and I get to the same point.

    Hi

        I am trying to get the TVP5147 working on the DM8148 too.

        Currently my system is able to recognize the TVP5147 and to map the TVP to /dev/video5 but I am having some problems to configure the V4L2 capture driver and the VPSS properly according to the standard. I am trying to capture NTSC 720x480, were you able to get this working at the end? If so, could you share which parameters did you use to configure V4L2 and VPSS?

         For the time being I am using:

    .video_if_mode = VPS_CAPT_VIDEO_IF_MODE_8BIT,

    .input_data_format = FVID2_DF_YUV422I_YUYV,

    .std = V4L2_STD_NTSC,

    buf_obj->fmt.fmt.pix.field = V4L2_FIELD_INTERLACED;

    mbus_framefmt.code = V4L2_MBUS_FMT_UYVY8_2X8;

    Finally I am using this to configure the preset but I am not completely sure if it is fine 

    inst->video.cur_dv_preset.preset = V4L2_DV_480P59_94;

    Thanks in advance for the help

    I add tvp5147 port work through CVBS(VIP1 PORTB) on  the DM8148 EVM too,and get the same error VPSS_FVID2: create handle is NULL.

    Hi,

       In the DM8168-EVM we got the TVP5147 working with V4L2, you can find more info here:
