Low Latency IMX412 Driver

[Matthew Wellner]

Hopefully this isn't something obvious that I am missed, but I was trying to follow the "Low Latency Video Streaming" instructions and after downloading and installing the optimized drivers, I am still having voxl-camera-server crash (I get "Aborted" a few seconds after the service starts) when I configure a video stream with greater than 30 FPS. I'm on voxl-suite 1.2.0 and system image 1.7.6-M0054-14.1a-perf.

Here is the output of dmesg when I get the "Aborted" message:

If I change the FPS setting to 30fps, everything will run, but with a latency hovering around 45-50ms. Also, if I enable preview with the suggested preview resolution, voxl-camera-server will error out. Do I need to update my VOXL2 image? Thanks in advance!

[Alex Kushleyev]

@Matthew-Wellner , there are a few things going on:

The drivers for IMX412 which are referenced from https://docs.modalai.com/camera-video/low-latency-video-streaming/ and dated 20250311 have a stability issue at full frame resolution at 60fps, as noted here : https://docs.modalai.com/camera-video/low-latency-video-streaming/#imx412-operating-modes

In your configuration you are requesting the full frame encoded video at 60fps (4056x3040 @60fps). If you are using older IMX412 drivers, and the 4056x3040@60 mode is also present, it will also have the same issue. The issue is that in this mode the time different between the EOF (End of Frame) and SOF (Start of Frame) is very small and the system does not have enough time to handle consecutive frames coming in with almost no break.

If you are using those low latency drivers from 20250311, you should check out an update in the following post, where a newer version was released with stable 4040x3040@60. https://forum.modalai.com/topic/4281/imx412-fpv/11?_=1745262450580 . Please note that the resolution should be 4040x3040 not 4056x3040, which is very small difference from the user's perspective.

The other part of the issue is that since SDK 1.2.0 we have improved the camera server stability (mainly by forcing it to run on the upper 4 CPU cores), which helped solved virtually all remaining issues related to camera server aborting. Are you able to upgrade your system to 1.4.0-2 or later? If you do not want to do any system upgrades, you should at least upgrade the IMX412 drivers to version 20250409 and may want to drop your FPS from 60 to 50 or 55 in order to help camera server avoid issues when running on the lower cores.

I will update the low latency instructions to recommend using the latest IMX412 drivers from 20250409.

Alex

[Matthew Wellner]

@Alex-Kushleyev Thanks for the help! I thought I wasn't requesting the full frame encoded since my en_large_video parameter in the configuration is set to false. Should I remove the references to those parameters completely?

I can do the update to 1.4.0-2+. I just need to refresh myself on the procedure.

[Matthew Wellner]

@Alex-Kushleyev I just tried upgrading from 1.2.0 to 1.4.1 and the installation script just hangs when I try to execute ./install.sh from my host computer. I am trying to run it from a Mac, but I am pretty sure I upgraded the SDK previously using the same computer. Let me know if you have any ideas. Thanks again!

[Alex Kushleyev]

@Matthew-Wellner , you are right. if the stream is disabled, its resolution will not affect the camera resolution. However, you requested the small stream to have resolution 1280x720 and the camera drivers for low latency do not have a native 1280x720@60 camera mode, so the pipeline selected the 4K60 or full frame 60fps, which was causing the issue. So the solution should be the same.

If you wanted to fix this, you should enable preview ("en_preview": true, "en_raw_preview": true) and you already have preview_widht / height set to 1936x1080 (and 60fps is available), so the pipeline will be forced to select 1936x1080@60, which should not have any issues.

You can confirm which camera mode was selected by the camera pipeline using instructions here : https://docs.modalai.com/camera-video/low-latency-video-streaming/#how-to-confirm-which-camera-resolution-was-selected-by-the-pipeline

Regarding the issue with updating SDK, i am not sure. Have you every done it before?

Alex

[Matthew Wellner]

@Alex-Kushleyev Thanks! I was able to get the update working. I needed to replace the "./" in the script with "bash" and then everything worked flawlessly.

I am going through and setting things up after the update, but I will give the configuration change a try shortly. When I update to the low latency drivers, I just need to drop them in the /usr/lib/camera directory, right?

thread is locked to cores: 4 5 6 7

I tried with my old configuration as well, but all I am getting is the message "thread is locked to cores: 4 5 6 7". I am not sure how to fix this.

[tom]

@Matthew-Wellner That isn't an error message. We manually set the cores voxl-camera-server is allowed to use in order to maximize performance

[Matthew Wellner]

@tom - Thanks for the clarification.

I thought it was an error because the server just dies without any other message immediately after the thread locked message. I'll go through everything again to see if I am missing something.

[Matthew Wellner]

@Alex-Kushleyev and @tom

I am getting the output below in logcat when I try and run the camera server. Did I miss a configuration / initialization step after updating the SDK?

@Matthew-Wellner , did you update to sdk 1.4.1? Can you please let me know what camera(s) you have connected (and which camera port) and the contents of your /usr/lib/camera? Does voxl-camera-server -l detect any cameras?

Alex

[Alex Kushleyev]

It seems that camera server gets stuck after

thread is locked to cores: 4 5 6 7

Can you please run voxl-camera-server -d 0 to enable full debugging prints and see if anything prints after that ?

Thank you

Alex

[Matthew Wellner]

@Alex-Kushleyev I updated to 1.4.1 and I have an IMX412 attached to port J7 upper.

voxl-camera-server -l crashes similarly to when I try to run the server normally (it just exits and logcat has the same output as above)

If I run "voxl-camera-server -d 0" it says that it doesn't recognize any cameras.

[Matthew Wellner]

@Alex-Kushleyev I moved the low latency .bin files into /usr/share/modalai/chi-cdk/imx412-fpv/ and the .so file into /usr/lib/camera. Was I not supposed to do that?

[Alex Kushleyev]

@Matthew-Wellner , both the .so and sensormodule(s) files need to go to /usr/lib/camera !

/usr/share/modalai/chi-cdk is used to store all the camera drivers that we ship with the SDK, but they are not used from this location. You either need to copy the correct sensormodule files from chi-cdk location into /usr/lib/camera/ or run voxl-configure-cameras script, which will do it based on a standard config.

Sorry for the confusion.

Alex

[Matthew Wellner]

@Alex-Kushleyev I fixed the drivers and got back to the issue I was having where the voxl-camera-server would just die after a short time. Here is the output from voxl-camera-server -d 0:

@Matthew-Wellner , thanks, that is looking better.

Now, two questions..

• which version of the IMX412 drivers are you using now?
• does the error still happen if you change the FPS to 30? what about 50?

Alex

[Matthew Wellner]

@Alex-Kushleyev

• I downloaded and installed the low latency drivers found on the low latency tutorial page -> https://docs.modalai.com/camera-video/low-latency-video-streaming/
• Yes it still occurs for... 30, 50, 60, & 90

Thanks again for the help!

@Matthew-Wellner,

Is any configuration at all working? I wonder if this is a hardware issue.

I will set up the exact use case and test. By the way i have recently updated the instructions you are referencing with updated imx412 drivers, so please double check the date on the driver zip file. Meanwhile, can you also post dmesg output after the camera server aborts? This can help spot a hardware issue.

Alex

@Alex-Kushleyev - Thanks again!
