I am not a “camera guy”, but I immediately understand the need to find out what nvcamerasrc is. You might look at this:
[url]https://devtalk.nvidia.com/default/topic/1025532/jetson-tx2/what-does-nvcamerasrc-do-/post/5215968/#5215968[/url]
The following is from a TX1, but steps should still be valid on methods to find nvcamerasrc:
[url]https://devtalk.nvidia.com/default/topic/1027596/jetson-tx1/failed-to-access-the-onboard-camera-using-nvcamerasrc-/[/url]
Since I don’t know much about cameras I am struggling a bit, but I am thinking this is a similar question:
[url]https://devtalk.nvidia.com/default/topic/1023782/jetson-tx2/how-to-capture-and-display-using-nvcamerasrc-on-tx2-/[/url]
Hopefully someone else knowing more about cameras will have a more useful answer.
Good day, I found video0 in /dev folder. I changed driver ADV782 for TxB and AIN3.
I tested video input with next command:
v4l2-ctl --set-fmt-video=width=640,height=480,pixelformat=RG10 --stream-mmap --stream-count=1 -d /dev/video0 --stream-to=ov5693.raw
In dmesg I received next feedback:
[ 607.835606] adv7482 6-0070: Detected the PAL video input signal
[ 607.837781] adv7482 6-0070: Detected the PAL video input signal

[ 608.062187] video4linux video0: frame start syncpt timeout!0
Message
[ 607.865096] vi vi: Selected no CSI lane, cannot do calibration
I received because used csi with 1-lane
Why could I get a message
video4linux video0: frame start syncpt timeout!0
?
My dtsi:
https://yadi.sk/d/V6UwvPcs49MIHQ
Change num_csi_lanes = <12>; at line 113 to see if it work.
I tryed change num_csi_lanes, but nothing has changed.I tryed stay on the line TXB CSI0P and I saw signal with period 25 microSec, on the clock perid was 20 nSec.
It means, that ADV7482 working normally.
My question: how I can test, that I right working with csi input on Tegra?
When I use command:
gst-launch-1.0 v4l2src device=/dev/video0 ! nvvidconv ! "video/x-raw(memory:NVMM),format=I420" ! nvvidconv ! omxh264enc ! flvmux ! filesink location=2019-02-25_13-05-00.flv
I receive green display

This is good new. Because it interlace frame so you will get odd frame and then even frame sequently. So you have to save odd frame and even frame and do the deinterlace algorithm to get full frame or by your way.
If I switch on progressive mode on ADV7482, then CSI input on tegra will be work correct?
P.S. Sorry for my bad english)
If ADV7482 can process progressive input then i think it will work. I have not tested yet.
In hardware manual write:
The format of the output data from the SDP is always 8-bit ITU-BT656(p.29 ADV748x_HrdwareManual)
It’s mean, that we can’t change interlaced to progressive output from ADV7482. And you right:
Hi!
I’m trying to use this chip ADV7482 on TX2, Has anyone done this? Can help-me?
Thanks!
@9iggor6 and @haihoangsoftware
Have you tried to use ADV7482 with newer versions of Jetapck with linux kernel 4.9?
