IMX6 SoloX VADC

lucapisani — Wed, 13 Jan 2016 15:35:01 GMT

Hi all,

I'm using a board based on sabre-sd iMX6 SoloX. The kernel base is 3.14.28_1.0.0_ga.

I would know how to use VADC input with Linux to have the stream of an analog camera.

I think that everything is set fine but I cannot have a clean image returned. I also think that part of the documantation is wrong in the pdf "i.MX_6_Linux_Reference_Manual.pdf" downloaded in the documentation package "fsl-yocto-3.14.28-1.0.0.gz"

this is my dts (the analog camera is connected to VADC_IN0 and GND)

&csi1 {
status = "okay";
port {
       csi1_ep: endpoint {
            remote-endpoint = <&vadc_ep>;
       };
};
};
&vadc {
vadc_in = <0>;   /* VADC_IN0 */
csi_id = <0>;      /* csi id 0 -> csi 1 */
status = "okay";
port {
       vadc_ep: endpoint {
            remote-endpoint = <&csi1_ep>;
};
};
};

In the doc file i.MX_6_Linux_Reference_Manual.pdf in the chapter 57 (VADC) in the "Unit Test" part I found this:

Before running the unit test, make sure that the following modules are loaded:
• insmod fsl_csi.ko
• insmod mxc_vadc_tvin.ko
• insmod csi_v4l2_capture.ko

BUT no one of these modules exists in the kernel 3.14.28

The modules loaded at boot are MXC_VADC and mx6s_capture (VIDEO_MXC_CSI_CAMERA).

:~$ lsmod
......
mxc_vadc 8466 1
mx6s_capture 17061 0

this the return from dmesg:

[   10.372159] CSI: Registered sensor subdevice: fsl_vadc
[   10.392807] wait vadc auto detect video mode...
[   10.811833] video mode NTSC
[   10.811839] vadc driver loaded

To test the source the documentation say this:

Run the unit test:
/unit_tests/csi_v4l2_tvin.out -d /dev/video<x>

BUT this file not exist. I tried recompiling the unit test (I used imx-test-5.2.tar.gz) or using a Yocto precompiled sdcard image for iMX6 SoloX SDB.

The closest test seems be "mx6s_v4l2_capture.out"

If I run :

udooer@udooneo:/$ ./mx6s_v4l2_capture.out -l
open video device /dev/video0
Found v4l2 capture device /dev/video0
pixelformat (output by camera): YUV4
CaptureMode=0, Width=720, Height=480 30.000 fps

Seems that the camera is recognized.

The only test I'm able to do with this file is capture a video with this command:

/unit_test/mx6s_v4l2_capture.out -ow 720 -oh 480 -d /dev/video0 -fr 30 -of test_vadc.yuv

How should I reproduce this video?

The best result that I've accomplished is by running this mplayer command:

mplayer -demuxer rawvideo -rawvideo w=720:h=480:format=rgb32 test_vadc.yuv

the video is played at high speed and the colors are wrong(probably the blue and green are exchanged). A screenshot in attachement.

Sorry for the long post. I would know how to use correctly the VADC on the iMX6 SoloX.

how to save correctly a video or stream the video in the video output ? etc.

Also how to save a picture/frame?

The documentation does not help and looks outdated.

Try gstreamer instead. Some examples of using gstreamer can be found in the Section 7.3 of the attached document.

Have a great day,
Artur

Thanks,

I've already tried gstreamer without better results, however I will test it again.

Do you suggest to try to encode with gstreamer the video stream from /dev/video0 or reproduce with gstreamer the video saved with the mx6s_v4l2_capture.out ?

Re: IMX6 SoloX VADC

art — Wed, 20 Jan 2016 10:07:08 GMT

You can either preview the camera image or encode the camera stream with gstreamer. Do not use mx6s_v4l2_capture.out. Seems that the root cause of the problem is that the video comes interlaced from the camera, so, you have to de-interlace it before encoding.

Best Regards,

Artur

Hi Artur,

first of all thanks for your support.

i've tried other gstreamer test but without results.

I have in my system gstreamer 1.0 with gstreamer-imx plugin so I tried some test with imxv4l2videosrc, imxipuvideosink, imxeglvivsink elements but nothing is shown.

I've installed gst-fsl-plugins to be aligned with the docs. Also with imxv4l2src and imxv4l2sink elements there's no video output.

WARNING: erroneous pipeline: could not link imxv4l2src0 to imxv4l2sink0

I also tried to embed the interested modules "mxc_vadc" "mx6s_capture" "mxc_v4l2_capture" but with the same results.

I also tried to add the "deinterlace" elements in the pipeline (I'm not sure if I used it right) but without difference.

What next? What should I verify?

Best Regards,

Luca

Re: IMX6 SoloX VADC

Any help?

Re: IMX6 SoloX VADC

lucapisani — Tue, 02 Feb 2016 17:15:58 GMT

So,

wrong outdated documentation, and no any help from Freescale/NXP?

Can someone give me a command that should work with the VADC input in iMX6 SoloX since the docs isn't helpful?

Re: IMX6 SoloX VADC

osmarfrisonjun1 — Mon, 22 Feb 2016 16:28:01 GMT

Maybe it will help

VADC failed - i.MXSoloX

Regards.

Hi,

were you able to get the VADC to work with GStreamer? I have the same problem that I cannot seem to create a valid GStreamer pipeline

<STRIP>

EDIT: Nevermind. I got it to run with gst-launch-1.0 imxv4l2src device=/dev/video1 ! imxv4l2sink device=/dev/video0

The overlaysink is not working for some reason in combination with the imxv4l2src. However, it works with "videotestsrc":

gst-launch-1.0 imxv4l2src device=/dev/video1 ! overlaysink
====== IMXV4L2SRC: 4.0.9 build on Apr 20 2016 12:27:19. ======
display(/dev/fb0) resolution is (800x480).
====== OVERLAYSINK: 4.0.9 build on Apr 20 2016 12:27:26. ======
WARNING: erroneous pipeline: could not link imxv4l2src0 to overlaysink0

Re: IMX6 SoloX VADC

JohnDoe1z — Wed, 20 Apr 2016 15:39:53 GMT

Ok, I guess I cheered to soon. The pipeline gst-launch-1.0 imxv4l2src device=/dev/video1 ! imxv4l2sink device=/dev/video0 does result in a camera picture being shown, but also results in a CPU load of almost 100% which, of course, is unacceptable.

art: any advise on this topic?
