500w camera problem, failed to get image

I have a UYVY mipi camra, which support 400w(25601440) and 500w(25921944). 400w mode has been tuned through, but 500w mode is failing. Here is my information, please give me some ideas to solve the problem, thank you!

Following this guide,Jetson/l4t/Camera BringUp - eLinux.org
There are 3 condtions:

  1. jetosn board crash and reboot. By the way, I use Jetpack4.6 rev2.
  2. trace infomation looks fine, but no video turns out.

hello xumm_td,

may I know which JetPack release you’re working with?
BTW, according to Sensor Software Driver Programming, pixel_t has deprecated.
please use the following properties instead: mode_type/ csi_pixel_bit_depth/ pixel_phase.
thanks

Thanks for the info.
It’s Jetpack4.6.

Hi，
I would like to redescribe my question.
Since my camera switching mode process takes longer, I think a few of the previous phenomena are related to this. Now ignore previous questions.for now.

Question: nvv4l2camerasrc VS. v4l2src

nvv4l2camerasrc works fine on 2560*1440 mode

gst-launch-1.0 nvv4l2camerasrc device=/dev/video0 ! "video/x-raw(memory:NVMM),format=(string)UYVY, width=(int)2560, height=(int)1440,framerate=30/1" ! nvvidconv ! "video/x-raw(memory:NVMM),format=(string)NV12" ! nvoverlaysink sync=false

nvv4l2camerasrc shows wrong image on 2592*1944 mode while v4l2src works fine

  • nvv4l2camerasrc
gst-launch-1.0 nvv4l2camerasrc device=/dev/video0 ! "video/x-raw(memory:NVMM),format=(string)UYVY, width=(int)2592, height=(int)1944,framerate=20/1" ! nvvidconv ! "video/x-raw(memory:NVMM),format=(string)I420" ! nvoverlaysink sync=false

Gives picture like this:

5aa55afd844afbf050d366692ae3edb
5aa55afd844afbf050d366692ae3edb1866×1096 202 KB

  • v4l2src works fine
gst-launch-1.0 v4l2src device=/dev/video0 ! "video/x-raw,format=(string)UYVY, width=(int)2592, height=(int)1944,framerate=20/1" ! nvvidconv ! "video/x-raw(memory:NVMM),format=(string)I420" ! nvoverlaysink sync=false

Let me thank you in advance for your help.

6

hello xumm_td,

how about using NV12 instead of I420 for the video converter?

7

Hi,
@JerryChang

gst-launch-1.0 nvv4l2camerasrc device=/dev/video0 ! "video/x-raw(memory:NVMM),format=(string)UYVY, width=(int)2592, height=(int)1944" ! nvvidconv ! "video/x-raw(memory:NVMM),format=(string)NV12" ! nvoverlaysink sync=false

No improvement, still have the same problem.

8

hello xumm_td,

could you please share the kernel and VI tracing logs, please check whether it output the same error logs?

9

You can ignore the logs mentioned at the beginning of my post.
I think both dmesg and trace are in normal state and no errors are reported.

hello xumm_td,

it looks SOF/EOF has sending to VI engine, it might be display side issue,
could you please try running fpsdisplaysink and fakesink, which disable preview and shows frame-rate only.
for example,
... nvvidconv ! 'video/x-raw(memory:NVMM),format=I420' ! fpsdisplaysink text-overlay=0 video-sink=fakesink sync=0 -v

11 
gst-launch-1.0 nvv4l2camerasrc device=/dev/video0 ! "video/x-raw(memory:NVMM),format=(string)UYVY, width=(int)2592, height=(int)1944" ! nvvidconv ! 'video/x-raw(memory:NVMM),format=I420' ! fpsdisplaysink text-overlay=0 video-sink=fakesink sync=0 -v

Thanks for you apply. This cmd works.

What can I use instead of nvoverlaysink?

12

hello xumm_td,

this might due to your display monitor not support such resolution,
please have a try to use nvvidconv to scale the output frames as standard 1080p for testing.
for example,
...! nvvidconv ! 'video/x-raw(memory:NVMM), format=(string)NV12, width=1920, height=1080' ! nvoverlaysink -ev

13

Hi Jerry,
My display monitor is 4K size, and your new cmd can not solve the problem.
I don’t think the previous fpsdisplaysink solves the problem. The problem now is that the image is error, while the pipleline is working normally and not reporting an error.

I also tried to do h264 recording and it shows the same error image as PREVIEW. The image below was taken from the video.

image

Using nvv4l2camerasrc does not work properly(wrong image), while using v4l2src does. Both PREVIEW and h264 video.
I think the key point of the problem is still on the difference between these two plugins.

15

hello xumm_td,

it should be alignment issue,
could you please have a try to use preferred_stride to configure the buffer alignment,
i.e. $ v4l2-ctl -d /dev/video0 --set-ctrl preferred_stride=5376
after that, launching the same resolution with nvv4l2camerasrc.

if this still not works,
you may modify your low-level driver to meet 64-alignment,
if the buffers are passing to VIC, it’ll need to have alignment with 256.

Hi,
Thanks for your reply. I think that probably be the key point.

preferred_stride=5376 works !!

May I ask how did you calculate this value? 2592—64align–>2624—UYVYmode,*2–5248…

Thank you for your patience and support.

hello xumm_td,

YUYV: 1 pixel = 2 bytes.
2592x2/256 = 20.25, you’ll need to revise the alignment to 21. so, 256x21 = 5376.
internal driver called int NvBufferGetParams() and check the _NvBufferParams::pitch for the pitch of each planes used by hardware buffer.

hence,
you may need to revise the code to adjust the values for your use-case,
thanks

Got it, thank you very much!
