我在gst-ai-usb-camera-app也遇到了同样的问题
建议您确认是否安装qcom-video-firmware
你在配置时没有碰到 install_ppa_pkgs.sh - E: Unable to correct problems, you have held broken packages. · Issue #10 · rubikpi-ai/rubikpi-script这个问题吗
直接运行./install_ppa_pkgs.sh 是存在问题的,这个情况你可以按照教程立刻复现的
如果强行安装这个应用则会ubuntu@ubuntu:~/gst-plugins-qti-oss-1.0.r1.06800/gst-sample-apps/gst-ai-usb-camera-app/build$ sudo apt install qcom-video-firmware

没喔，怎么安装？install_ppa_pkgs.sh 已经调过一次了
我们这边目前测试未复现该问题。
若您使用的是最新的 Ubuntu 版本，且安装了 linux-firmware-dragonwing，建议移除并安装 qcom-video-firmware。若在安装过程中涉及其他包，建议寻找“可同时保留”的解决方案，或按需单独安装。
我们这边测试验证过，qcom-video-firmware 与 libqnn1、qnn-tools、libsnpe-dev、qcom-fastrpc1 等库/工具可以兼容并正常使用。
另外，您也可以考虑重新烧写后，运行 install_ppa_pkgs.sh 脚本进行环境安装；该脚本默认会安装 qcom-video-firmware。
若已经安装了 linux-firmware-dragonwing， 可以参考下列命令
sudo apt update
sudo apt remove linux-firmware-dragonwing
sudo apt install qcom-video-firmware
我们已复现该问题，Canonical 正在调查，若有进展会立即更新上来
