DM8168 Capture YUV and save with NVP6324 error

Hello,

I have some problems about video capture on DM8168,

1080P AHD video –> NVP6324 –> DM8168, in arch/arm/mach-omap2/ti81x_vss.c, the port has been configured as the following:

Anyone can help ?

thanks in advance.

Chris Meng：

你好，

请问你使用的软件是DVR RDK4.01么？

请问NVP6324和DM8168连接时通过4路8-bit 656么？如果是，建议参考TVP5158的相关驱动。DVR RDK支持4片TVP5158的输入。

Hi Chris,

感谢回复。我这边使用的是：DVR RDK V4. 1 GA Release

NVP6324 通过4路 bt656输出4路AHD视频到dm8168，分辨率是：1080P30fps

您提到的TVP5158，驱动是在哪个位置呢？

[22:01:29:957] [m3vpss ]  26666: Assertion @ Line: 832 in links_m3vpss/capture/captureLink_drv.c: pInst->captureVipHandle != NULL : failed !!!

这个错误，是需要debug哪个部分呢？video decoder驱动还是applicaton呢？

第一次接触这个平台，请多指教。

回复 Chris Meng:

你好，感谢回复。

我看到了这个部分的code，还是很困惑。
video decoder的驱动不是应该在linux kernel这一端去实现吗，还是说这里的tvp5158的驱动是在dsp端的呢？
从这里编译出来的bin或执行程序要如何更新到板子上去呢？

下面wiki描述的方式适用8168吗？
processors.wiki.ti.com/…/DM81xx_AM38xx_Adding_External_Decoders_to_V4L2_Capture_Driver

我看到论坛有不少的vin采集，都是arm/arch/mach-omap2/下的vpss，加入新的video decoder。

谢谢！

回复 user6313936:

你好，

TVP5158是比较特殊，在M3控制，你可以参考其BT656部分。

在Linux下实现video decoder的驱动也是可以的。

非常感谢您的回复。

可以帮我看看我的配置吗？

IO配置，static void __init ti81xx_video_mux(void)在这里，

// video in channel 1 by @deepin
omap_mux_init_signal("vin0_d8", TI81XX_MUX_MODE1);
omap_mux_init_signal("vin0_d9", TI81XX_MUX_MODE1);
omap_mux_init_signal("vin0_d10", TI81XX_MUX_MODE1);
omap_mux_init_signal("vin0_d11", TI81XX_MUX_MODE1);
omap_mux_init_signal("vin0_d12", TI81XX_MUX_MODE1);
omap_mux_init_signal("vin0_d13", TI81XX_MUX_MODE1);
omap_mux_init_signal("vin0_d14", TI81XX_MUX_MODE1);
omap_mux_init_signal("vin0_d15", TI81XX_MUX_MODE1);
omap_mux_init_signal("vin0_clk1", TI81XX_MUX_MODE2);

vpss的配置在 static struct ti81xxvin_subdev_info hdvpss_capture_sdev_info[] ，是这样的，

{
.name = NVP6324_INST,
.board_info =
{
I2C_BOARD_INFO(NVP6324_INST, NVP6324_SADDR),
},
.vip_port_cfg =
{
.ctrlChanSel = VPS_VIP_CTRL_CHAN_SEL_15_8,
.ancChSel8b = VPS_VIP_ANC_CH_SEL_DONT_CARE,
.pixClkEdgePol = VPS_VIP_PIX_CLK_EDGE_POL_FALLING,
.invertFidPol = 0,
.embConfig =
{
.errCorrEnable = 1,
.srcNumPos = VPS_VIP_SRC_NUM_POS_DONT_CARE,
.isMaxChan3Bits = 0,
},
.disConfig =
{
.fidSkewPostCnt = 0,
.fidSkewPreCnt = 0,
.lineCaptureStyle = VPS_VIP_LINE_CAPTURE_STYLE_DONT_CARE,
.fidDetectMode = VPS_VIP_FID_DETECT_MODE_DONT_CARE,
.actvidPol = VPS_VIP_POLARITY_DONT_CARE,
.vsyncPol = VPS_VIP_POLARITY_DONT_CARE,
.hsyncPol = VPS_VIP_POLARITY_DONT_CARE,
}
},
.video_capture_mode = VPS_CAPT_VIDEO_CAPTURE_MODE_SINGLE_CH_NON_MUX_EMBEDDED_SYNC,
.video_if_mode = VPS_CAPT_VIDEO_IF_MODE_8BIT,
.input_data_format =FVID2_DF_YUV422I_UYVY,
},
NVP6324配置成了1080P30fps，YUV422，但是在运行程序capture yuv and save，在syslink 创建capture句柄
就失败了，我查看了下code，在这个函数：

/* * Create global VIP capture handle, used for dequeue, * queue from all active captures */ pObj->fvidHandleVipAll = FVID2_create(FVID2_VPS_CAPT_VIP_DRV, VPS_CAPT_INST_VIP_ALL, NULL, NULL, NULL); UTILS_assert(pObj->fvidHandleVipAll != NULL);

这会是哪里没有配置正确呢？
