Hello!

I wrote programm to capture image from CMOS-matrix, encode JPEG and to send image via RTSP_stream. I have successfully see MJPEG stream via VLC, but I get green image and I think that IPIPE can solve this problem.

I looked sample in dvsdk_2_00_00_22/PSP_02_00_00_140/examples/dm355/ipipe and wrote my function:

short initIPIPE(Buffer_Handle *hBufPtr)
{
    struct ipipe_reqbufs reqbufs;
    struct ipipe_buffer t_buff;
    int ret;
    ipipeFd = open(IPIPE_DEVICE, O_RDWR);
    if (-1 == ipipeFd) {
        cout << "Can't open " << IPIPE_DEVICE << "!" << endl;
        return ipipeFd;
    }
    ret = configureIPIPE(ipipeFd);
    if (0 != ret) {
        cout << "Can't configure IPIPE!" << endl;
        return ret;
    }
    reqbufs.buf_type = IPIPE_BUF_OUT;
    reqbufs.size = imageHeight * (((imageWidth << 1) + 31) & (~31));
    reqbufs.count = NUM_BUF;
    ret = ioctl(ipipeFd, IPIPE_REQBUF, &reqbufs);
    if (-1 == ret ) {
        cout << "Can't get IPIPE requested buffer ("  << strerror(errno) << "!" << endl;
    return ret;
    }
    t_buff.index = 0;
    t_buff.buf_type = IPIPE_BUF_OUT;
    ret = ioctl(ipipeFd, IPIPE_QUERYBUF, &t_buff);
    if (-1 == ret) {
        cout << "Can't get IPIPE out buffer address ("  << strerror(errno) << "!" << endl;
    return ret;
    }
    BufferGfx_Attrs gfxAttrs  = BufferGfx_Attrs_DEFAULT;
    gfxAttrs.dim.width        = imageWidth;
    gfxAttrs.dim.height       = imageHeight;
    gfxAttrs.dim.lineLength   = imageWidth << 1;
    gfxAttrs.colorSpace       = ColorSpace_UYVY;
    gfxAttrs.bAttrs.reference = TRUE;
    Buffer_setNumBytesUsed(*hBufPtr, t_buff.size);
    Int8 *virtPtr;
    virtPtr = (Int8 *)mmap(NULL, t_buff.size, PROT_READ | PROT_WRITE,  MAP_SHARED, ipipeFd, t_buff.offset);
    if (virtPtr == MAP_FAILED) {
        cout << "Can't mmap IPIPE buffer (" << strerror(errno) << ")!" << endl;
        return -1;
    }
    Buffer_setUseMask(*hBufPtr, gfxAttrs.bAttrs.useMask);
    Buffer_setUserPtr(*hBufPtr, virtPtr);
    return 0;
}

short processIPIPE(Buffer_Handle hInBuf, Buffer_Handle hOutBuf)
{
    struct ipipe_convert convert;
    if (-1 == configureIPIPE(ipipeFd)) {
        cout << "Can't configure IPIPE!" << endl;
        return -1;
    }
    convert.in_buff.buf_type = IPIPE_BUF_IN;
    convert.in_buff.index = -1;
    convert.in_buff.offset = (unsigned int)Buffer_getUserPtr(hInBuf);
    convert.in_buff.size = Buffer_getNumBytesUsed(hInBuf);
    convert.out_buff.index = -1;
    convert.out_buff.buf_type = IPIPE_BUF_OUT;
    convert.out_buff.offset = (unsigned int)Buffer_getUserPtr(hOutBuf);
    convert.out_buff.size = Buffer_getNumBytesUsed(hOutBuf);
    if (-1 == ioctl(ipipeFd, IPIPE_START, &convert)) {
        cout << "IPIPE don't convert image!" << endl;
        return -1;
    }
    return 0;
}

And programm:
Buffer_Handle hIPIPEBuf;
if (-1 == initIPIPE(&hIPIPEBuf)) {
        cout << "Can't init IPIPE!" << endl;
        closeIPIPE(hIPIPEBuf);
        clear();
}
while (true) {
    if (Dmai_EOK != Capture_get(hCapture, &hCapBuf)) {
        cout << "Failed to get capture buffer!" << endl;
        clear();
    }
    if (Dmai_EOK != Framecopy_execute(hFramecopy, hCapBuf, hDstBuf)) {
        cout << "Failed to execute frame copy job!" << endl;
        clear();

    }
    processIPIPE(hDstBuf, hIPIPEBuf);
    ..........................
}

When I try to get stream via vlc I get Floating point exception.

I have found what problem in the ioctl(ipipeFd, IPIPE_START, &convert), but why?

Where I have error and how can I solve it?

Thank you and excuse me for my bad english.

    Hi,

    Kirill
    I have found what problem in the ioctl(ipipeFd, IPIPE_START, &convert), but why?

    Can you provide the exact message that you get when IOCTL IPIPE_START is called? Based on the error message, we can try to analyse the parameters that you are setting. I hope you are using IPIPE only as in resizer mode as it seems your input is a YUV data coming from TVP5146.

    Regards,

    Anshuman

    Hello Anshuman Saxena and thank you for your reply!

    I don't get any error.

    My function:
    ..................................
    cout << "before ipipe_start" << endl;
    if (-1 == ioctl(ipipeFd, IPIPE_START, &convert)) {
            cout << "IPIPE don't convert image!" << endl;
            return -1;
    }
    cout << "after ipipe_start" << endl;
    ...................................

    And programm output:
    before ipipe_start                                                                                                                                                                                         
    CPU load 16%

    CPU load 0%

    Difference CPU load output in the 10 sec.

    Hi,

    There can be multiple reasons why the interrupt did not come. It depends on parameters that are being set for IPIPE, RSZ, IPIPEIF and CCDC. Can you provide me all the registers for the above modules?

    I have not used the DVSDK 2.00.xx for DM355, so i might not be able to directly comment on the driver details, but surely looking at the registers, i can help.

    Hi,

    It seems like the following two lines might be possible cause of the problem. Why have you disabled the two resizer outputs? These are the output port of the IPIPE and hence if it is disbaled, you are not going to get any output and hence no interrupt.

    Kirill
    params.rsz_en[0] = DISABLE;
    params.rsz_en[1] = DISABLE;

    BTW, i asked for the actual physical register values. Can you provide the register values to me? You can refer to VPFE PRG for DM355 to get the exact address.

    Regards,

    Anshuman

    Thank you Anshuman for your reply!

    I reconfigured IPIPE:
    //Resizer Rescale Parameters
    if (imageWidth > 640) {
        params.rsz_rsc_param[0].rsz_o_vsz = imageHeight - 1;
            params.rsz_rsc_param[0].rsz_o_hsz = imageWidth -1;
            params.rsz_rsc_param[0].rsz_v_dif = (imageHeight * 256 / imageHeight);
            params.rsz_rsc_param[0].rsz_h_dif = (imageWidth * 256 / imageWidth);
            params.rsz_rsc_param[0].rsz_h_typ = CUBIC;
            params.rsz_rsc_param[0].rsz_h_lse_sel = INTERNAL_VALUE;
    } else {
            params.rsz_rsc_param[1].rsz_o_vsz = imageHeight - 1;
            params.rsz_rsc_param[1].rsz_o_hsz = imageWidth -1;
            params.rsz_rsc_param[1].rsz_v_dif = (imageHeight * 256 / imageHeight);
            params.rsz_rsc_param[1].rsz_h_dif = (imageWidth * 256 / imageWidth);
            params.rsz_rsc_param[1].rsz_h_typ = CUBIC;
            params.rsz_rsc_param[1].rsz_h_lse_sel = INTERNAL_VALUE;
    }
    //Resizer RGB Conversion Parameters
    if (imageWidth > 640) {
            params.rsz2rgb[0].rsz_rgb_en = ENABLE;
            params.rsz2rgb[0].rsz_rgb_typ = OUTPUT_16BIT;
            params.rsz2rgb[0].rsz_rgb_msk0 = NOMASK;
            params.rsz2rgb[0].rsz_rgb_msk1 = NOMASK;
    } else {
            params.rsz2rgb[1].rsz_rgb_en = ENABLE;
            params.rsz2rgb[1].rsz_rgb_typ = OUTPUT_16BIT;
            params.rsz2rgb[1].rsz_rgb_msk0 = NOMASK;
            params.rsz2rgb[1].rsz_rgb_msk1 = NOMASK;
    }
    //Resizer External Memory Parameters
    if (imageWidth > 640) {
            params.ext_mem_param[0].rsz_sdr_oft = ((imageWidth * 2+ 31)&(~31));
            params.ext_mem_param[0].rsz_sdr_ptr_e = imageHeight;
    } else {
            params.ext_mem_param[1].rsz_sdr_oft = ((imageWidth * 2+ 31)&(~31));
            params.ext_mem_param[1].rsz_sdr_ptr_e = imageHeight;
    }
    if (imageWidth > 640) {
            params.rsz_en[0] = ENABLE;
            params.rsz_en[1] = DISABLE;
    } else {
            params.rsz_en[0] = DISABLE;
            params.rsz_en[1] = ENABLE;
    }

    But this don't solve problem.

    How can I get physical register values?

    You can use attached readl utility on the DM355 linux shell. Actually, i wanted to get the register dump for IPIPE, IPIPEIF and CCDC registers, not the VENC register. So can you provide those register details.

    Regards,

    Hello Anshuman!

    I have read SPRUF71a and run readl, but I am not sure that I use right values:
    - for CCDC ./readl 0x01c70600 0 0x15c
    - for IPIPEIF ./readl 0x01c70100 0 0x28
    - for IPIPE ./readl 0x01c71000 0 0x400

    I dump values before runing programm and after (files with after suffix).

    Also after last reconfiguration, when I enabled resize, output from programm changed:
    [0] @ 0x44231000 (0x86b80000 phys) numBytes 0 (614400) useMask 0 (1) ref no    
            Width 640, Height 480, LineLength 1280                                                                         
    before ipipe_start                                                             
    after ipipe_start                                                              
    before ipipe_start

    Now it seems that IPIPE can process one buffer, but then it stops again.
