# Hi-Res camera disconnect Source: https://forum.modalai.com/topic/510/hi-res-camera-disconnect Category: General Questions (https://forum.modalai.com/category/2/general-questions) Posted: 2021-10-25 02:21:58 UTC by wilkinsaf Replies: 5 · Views: 828 ## wilkinsaf · 2021-10-25 02:21:58 UTC Hello, We are experiencing interruptions with our cameras. We are actively seeing it in voxl-streamer, but believe it might be having an effect on flight stability as well (we are using VIO) When using voxl-streamer we are able to see the video feed for a few minutes, and then it cuts out. The main error we see is this ``` ERROR: Got 0 bytes. Expecting 40 closing FDs for client channel 0 ``` here it is in context ---------- hi-res camera ----------------- ``` yocto:~# voxl-streamer Using configuration file /etc/modalai/voxl-streamer.conf requesting name voxl-streamer0 with complete path /run/mpa/hires_preview/voxl-streamer0 connected after 1 attempt(s) Stream available at rtsp://127.0.0.1:8900/live A new client has connected to the RTSP server An existing client has disconnected from the RTSP server A new client has connected to the RTSP server WARNING: Got 59392 bytes.

Loose cable? A: I tried this on 2 different setups and had the same issue Q: Have you changed any default camera settings? A: No Q: What is your camera settings setup A: Hi-res + tracking (we have stereo too, but I can not seem to get any stream from them. tried voxl-inspect-cam but still not nothing) Q: What cameras are you using? A: Both tracking and hi-res from modalai Any insight would be much appreciated. Thank you for your time ## Reply by Chad Sweet (ModalAI staff) · 2021-10-25 17:04:41 UTC these issues don't seem to be common. Which version of software are you using? What else is running? Those data fell behind errors indicate that too much is running on the cpu. Can you test while also running voxl-inspect-cpu? ## Reply by wilkinsaf · 2021-10-25 17:44:39 UTC Thank you for the quick reply @Chad-Sweet Here is the version information ``` yocto:~# voxl-version cat: /etc/modalai/voxl-software-bundle-version.txt: No such file or directory -------------------------------------------------------------------------------- system-image: ModalAI 3.2.0 BUILDER: ekatzfey BUILD_TIME: 2021-02-05_19:54 kernel: #1 SMP PREEMPT Fri Feb 5 20:03:22 UTC 2021 3.18.71-perf factory-bundle: 1.0.1 (Yocto installation) -------------------------------------------------------------------------------- architecture: aarch64 processor: apq8096 os: GNU/Linux -------------------------------------------------------------------------------- voxl-suite: Package: voxl-suite Version: 0.3.4 Depends: voxl-utils (>= 0.6.0), libmodal_json (>= 0.3.4), libmodal_pipe (>= 1.7.8), librc_math (>= 1.1.4), libvoxl_io (>= 0.5.4), mavlink-camera-manager (>= 0.0.1), opencv (>= 4.5.1), openmp (>= 10.0.1), voxl-camera-server (>= 0.5.6), voxl-dfs-server (>= 0.0.7), voxl-docker-support (>= 1.1.1), voxl-gphoto2 (>= 0.0.5), voxl-hal3-tof-cam-ros (>= 0.0.5), voxl-imu-server (>= 0.7.8), voxl-modem (>= 0.11.0), voxl-mpa-tflite-server (>= 0.0.2), voxl-mpa-tools (>= 0.1.6), voxl-nodes (>= 0.1.3), voxl-qvio-server (>= 0.2.1), voxl-rtsp (>= 1.0.3), voxl-streamer (>= 0.2.1), voxl-vision-px4 (>= 0.8.1), voxl-vpn (>= 0.0.3) Status: install user installed Section: base Architecture: all Maintainer: james@modalai.com MD5Sum: e1e5bf1a125affe5036099f6ce895bed Size: 1818 Filename: voxl-suite_0.3.4.ipk Description: meta-package for voxl-suite stable release Installed-Time: 333 Package: voxl-suite Version: 0.2.0 Depends: docker, imu_app (= 0.0.6), libvoxl_io (= 0.5.2), voxl-cam-manager (= 0.2.2), voxl-docker-support (= 1.1.1), voxl-hal3-tof-cam-ros (= 0.0.2), voxl-modem (= 0.10.0), voxl-nodes (= 0.0.8), voxl-rtsp (= 1.0.2), voxl-utils (= 0.5.2), voxl-vision-px4 (= 0.6.8), voxl_imu (= 0.0.4), voxl-time-sync (= 0.0.1), voxl-vpn (= 0.0.2), librc_math (= 1.1.2), libmodal_pipe (= 1.2.2), modalai-vl (= 0.1.3) Status: unknown ok not-installed Section: base Architecture: armv7a Maintainer: james@modalai.com MD5Sum: af706cd3c1ea59f274f2ed9b93141f1d Size: 870 Filename: voxl-suite_0.2.0.ipk Description: meta-package to install all of the voxl-suite -------------------------------------------------------------------------------- ``` I will run voxl-inspect-cpu now ## Reply by wilkinsaf · 2021-10-25 17:57:27 UTC It appears I do not have voxl-inspect-cpu ``` yocto:~# ls /usr/bin/ | grep voxl voxl-backup voxl-calibrate-imu voxl-camera-server voxl-configure-camera-server voxl-configure-cameras voxl-configure-dfs voxl-configure-docker-support.sh voxl-configure-extrinsics voxl-configure-modem voxl-configure-mpa voxl-configure-qvio voxl-configure-vision-px4 voxl-dfs-server voxl-docker voxl-env voxl-fan voxl-gphoto2 voxl-gpio voxl-gpio-loopback voxl-hwscan voxl-i2c voxl-imu-server voxl-inspect-apriltag-config voxl-inspect-cam voxl-inspect-extrinsics voxl-inspect-imu voxl-inspect-points voxl-inspect-pose voxl-inspect-qvio voxl-inspect-services voxl-inspect-vibration voxl-kill-pipe voxl-logger voxl-modem voxl-modem-start.sh voxl-mpa-tflite-server voxl-perfmon voxl-px4-shell voxl-qvio-server voxl-replay voxl-reset-qvio voxl-rtsp voxl-spi voxl-streamer voxl-test-mavparser voxl-test-time voxl-time-sync voxl-uart-loopback voxl-version voxl-vision-px4 voxl-vpn-init voxl-wifi ``` Looking into how to download this tool now ## Reply by Guest · 2021-10-25 18:15:05 UTC Hi, It looks like you are using an older version of our software bundle (0.3.2 sys image + 0.3.4 sdk). Our current (0.3.3. sys image + 0.4.6 sdk) platform release can be found on our [downloads](https://developer.modalai.com/asset) page. That release contains significant stability improvements to camera server as well as a number of other tools and will make it much easier to debug the problem if it persists. ## Reply by wilkinsaf · 2021-10-25 18:40:30 UTC That is great to hear. Thanks @Alex-Gardner! I will update. I assumed I was on the latest as I had seen I was on factory bundle 1.0.1 and saw on this page: https://docs.modalai.com/downloads/ That the latest factory bundle was 1.0.1. ![32eb6578-ebff-4d43-b1ae-d2dc43d70f7e-image.png](https://forum.modalai.com/assets/uploads/files/1635187077739-32eb6578-ebff-4d43-b1ae-d2dc43d70f7e-image.png) Should I be paying attention to the ``` system-image: ModalAI 3.2.0 ``` When checking whether the system needs an update?
