  debian rootfs, ALSA headers
Posted by: jonsmirl - 11-06-2018, 06:38 PM - Forum: General Discussion on Lindenis V5 - Replies (7)

Did you guys build this, or is it copied from somewhere?

Basic rootfs
Download the basic rootfs from FTP server with user 'ftp' (password: lindeni) and store to debian directory.


It needs the ALSA headers installed into it.

I would recommend using buildroot instead of debian. buildroot will let you control exactly what is in the image you build.
https://buildroot.org/

With buildroot you can make a single config file that can make the V5 kernel, V5 uboot and even the examples. Then turn it all into an image.

  OpenCV and V5

Has anything been done to integrate the V5 AI hardware with OpenCV?

  Processing video from AHD cameras
Posted by: diaamant - 11-01-2018, 08:16 AM - Forum: General Discussion on Lindenis V5 - Replies (1)

We need to process the signal from the AHD cameras.
In the description (http://www.lindeni.org/lindenis-v5.html) in the section "Various interfaces" it is indicated: "4 x AHD"
The diagram (http://files.lindeni.org/lindenis-v5/dat...c-v1.1.pdf) on the second sheet shows the NCSI1 connection interface (AHD NVP6134c decoder chip). But in the scheme of this chip is not.
As I understand it, we just have the opportunity to connect to this interface through the AHD decoder. If this is the case, then I would ask you to consider the possibility of creating and placing an expansion card for sale (input of the AHD video signal)

  question about sample_cve_BDII in MPP_SAMPLE
Posted by: arglues - 11-01-2018, 03:12 AM - Forum: General Discussion on Lindenis V5 - Replies (2)

In this sample: sample_cve_BDII, it builds a depth picture from left and right YUV format file. 
While if we want to create yuv files from cmos sensor, that is mpi_ise work as input, we have to calibration both left and right camera to get inner and external parameters. Without these paraameters, the Binocular Vision is actually unvaliable.
Is there any document can be refer to do this?

  how to customize a classifier to detect other object?
Posted by: arglues - 11-01-2018, 03:01 AM - Forum: General Discussion on Lindenis V5 - Replies (5)

Hi,
In the document 《EVE应用API参考手册.pdf》page 6, the feature 10 said: “EVE提供的算法可以定制分类器,支持任意小变形刚性目标检测(人脸、车辆、车牌、行人、人头、头肩等其他重点目标)“, and "分类器可视化设计,提供一整套完整训练、调试、测试与评估工具".
where can we download these tools? We need design a special target classifer based on V5 platform.

  Fisheye correction
Posted by: jonsmirl - 10-31-2018, 11:35 PM - Forum: General Discussion on Lindenis V5 - Replies (1)

When using a single sensor, what is the difference between these three modes?

WARP_PANO180
WARP_NORMAL
WARP_UNDISTORT

WARP_NORMAL is especially confusing since it requires a 2:1 reduction in resolution and only supports 720P output.

  H264 Encoder Scaling Limit
Posted by: tylerjbrooks - 10-26-2018, 11:50 PM - Forum: General Discussion on Lindenis V5 - Replies (3)

If I try to encode a 3840x2160 image to a 640x360 image I get this message:

error  : cedarc <h264CheckCapability:2235>: error: scaler range is 0.25-8.0, but the request scaler[0.166667,0.170370]

Is there a way to increase the range?

I am setting up the encoder like this:
  VENC_CHN_ATTR_S ve_attr_;
  memset(&ve_attr_, 0, sizeof(VENC_CHN_ATTR_S));
  ve_attr_.VeAttr.Type = PT_H264;
  ve_attr_.VeAttr.MaxKeyInterval = 30;
  ve_attr_.VeAttr.SrcPicWidth = 3840;
  ve_attr_.VeAttr.SrcPicHeight = 2160;
  ve_attr_.VeAttr.Field = VIDEO_FIELD_FRAME;
  ve_attr_.VeAttr.PixelFormat = MM_PIXEL_FORMAT_YVU_SEMIPLANAR_420;
  ve_attr_.VeAttr.Rotate = ROTATE_NONE;
  ve_attr_.VeAttr.AttrH264e.bByFrame = TRUE;
  ve_attr_.VeAttr.AttrH264e.Profile = 2;
  ve_attr_.VeAttr.AttrH264e.MaxPicWidth =3840;
  ve_attr_.VeAttr.AttrH264e.MaxPicHeight = 2160;
  ve_attr_.VeAttr.AttrH264e.PicWidth = 640;
  ve_attr_.VeAttr.AttrH264e.PicHeight = 360;

ve_attr_.RcAttr.mRcMode = VENC_RC_MODE_H264CBR;
ve_attr_.RcAttr.mAttrH264Cbr.mGop = 30;
ve_attr_.RcAttr.mAttrH264Cbr.mSrcFrmRate = 30;
ve_attr_.RcAttr.mAttrH264Cbr.fr32DstFrmRate = 30;
ve_attr_.RcAttr.mAttrH264Cbr.mBitRate = 8 * 1024 * 1024;

  Encoding 4K Video
Posted by: tylerjbrooks - 10-25-2018, 12:17 AM - Forum: General Discussion on Lindenis V5 - Replies (4)

I would like to encode 3840x2160 video.  But there seems to be a limit of 3264x2160.  Is that true?

[VideoEnc_Component.c:433]       <setVbvBufferConfig>          Be careful! threshSize[8294400]bytes too large, reduce to 7MB
[VideoEnc_Component.c:478]       <setVbvBufferConfig>          bit rate is 8192Kb, set encode vbv size 12441600, frame length threshold 7340032


I am using the IMX317 sensor.
It is plugged into MIPI0.
I am using ISP_DEV_1 and VI_DEV_0.

Is there a datasheet for the IMX317 available in the wiki?

  How to enable low framerate mode
Posted by: tylerjbrooks - 10-21-2018, 10:54 PM - Forum: General Discussion on Lindenis V5 - Replies (1)

When I change the encoder framerate using AW_MPI_VENC_SetFrameRate() it tells me I have to 'enable soft frame rate control'.  How do I do that?

I am working with code that optimizes the bandwidth used on a network connection by varying the output framerate from the encoder.  Admittedly, it sets some 'weird' combinations.  My source is always 30fps but the optimization code might ask for 17fps from the encoder, for instance.  Is this allowed?

Here is an example of the warning message:
<VideoEncSetFrameRate>        Low framerate mode, dst:17, src:30, enable soft frame rate control!
