请问你是用普通的 SDK 还是用 SDK-AI ？
目前这个 demo 只支持 SDK-AI。
由于该 demo 配置项比较多。已经固化到固件了。
编译命令：
./build.sh device/rockchip/rv1126_rv1109/aio-rv1126-rkmedia-uvcc.mk

编译完成并烧录后在 PC 上位机执行：
/oem/usb_config.sh rndis
/userdata/firefly_rkmedia_vi_uvc_test -a /oem/etc/iqfiles/ -c /oem/usr/share/rtsp-nn.cfg -p /oem/usr/share/rknn_model/ssd_inception_v2_rv1109_rv1126.rknn -l /oem/usr/share/rknn_model/coco_labels_list.txt -b /oem/usr/share/rknn_model/box_priors.txt

复制代码

从哪里知道是SDK还是SDK-AI? SDK-AI这个名词我第一次看到, 不知这个名词来源哪里, 我是从如下地址下载的code.
  1. repo init  --no-clone-bundle --repo-url https://gitlab.com/firefly-linux/git-repo.git -u https://gitlab.com/firefly-linux/manifests.git -b master -m rv1126_rv1109_linux_release.xml

维基不够完善。
参考 https://wiki.t-firefly.com/zh_CN/CAM-C11262U/Source_code.html 中的源码编译获取代码。不过版本比较旧，没有 aio-rv1126-rkmedia-uvcc.mk 文件。我们这几天尽快发布最新的 SDK-AI 版本。

这里面的mk文件在维基上都有介绍。功能不包括 firefly_rkmedia_vi_uvc_test 。
作者: 799959745    时间: 2021-8-3 17:24
尝试以下步骤运行demo。
1、使用 sdk-ai uvcc 固件。官网下载固件。或者手动编译 ./build.sh cam-crv1109s2u-uvcc.mk
2、固件文件系统 /etc/init.d/S50usbdevice 和 sdk-ai-path/buildroot/board/rockchip/rv1126_rv1109/fs-overlay-uvc/etc/init.d/S50usbdevice 要一致
3、将 sdk-ai-path/app/firefly_rkmedia_uvc/1126/librkuvc/librkuvc.so 替换掉固件文件系统的 /usr/lib/librkuvc.so
4、将 sdk-ai-path/app/firefly_rkmedia_uvc/1126/libs/ 目录所有库文件拷贝到固件文件系统 /usr/lib/ 目录下
5、删除文件 /etc/init.d/S58_lunch_init

谢谢帮忙.
请教一下, step3 step4 里面SDK 中lib库路径是不是贴错了? 以step3 为例, librkuvc.so 有如下路径, 用任何一个push到固件文件系统即可吗?

$ f librkuvc.so
f./buildroot/output/firefly_rv1126_rv1109_uvcc/build/uvc_app/librkuvc.so
./buildroot/output/firefly_rv1126_rv1109_uvcc/host/arm-buildroot-linux-gnueabihf/sysroot/usr/lib/librkuvc.so

workaroud 解决:
  1. => /home/ws/AI_UVC_CAM-CRV1126S2U/external/uvc_app/uvc [Wed 11-11:05:23] C:1
  2. $ cp * /home/ws/AI_UVC_CAM-CRV1126S2U/buildroot/output/firefly_rv1126_rv1109_rkmedia_uvcc/build/firefly_rkmedia_uvc-1.0/uvc/
  3. cp#
复制代码


2. 此贴的主题问题,uvc的demo 如何正确运行呢?

2.1 如下默认方法执行失败,执行完这一步后adb 连接就断开了. 用adb ip:5555 shell 也不行.
  1. /oem/usb_config.sh rndis
复制代码


2.2 删除/etc/init.d/S58_lunch_init 后重启 adb 无法连接.
这个文件夹里面还有其他S**_lunch_init, 不确定删哪一个.

2.3 cd /oem;./RkLunch-stop.sh 之后再重复上述步骤2.1也无效.

使用以下 mk 文件编译出来的固件可以直接使用，不用操作板子。
./build.sh device/rockchip/rv1126_rv1109/aio-rv1126-rkmedia-uvcc.mk

固件烧进板子之后。电脑查看 /dev/video 是哪个节点，根据出现的节点修改 client.cpp 。
修改以下内容：
#define VIDEO_NODE 1

编译执行：
  1. cd sdk-ai-path/app/firefly_rkmedia_uvc/host/
  2. ./build.sh
  3. sudo ./client
  4. #正常运行的话就能看到信息了
  5. #程序还没完善，只能运行一次。想要再次打开只能重启板子。

太赞了, 已经导通!

可否再麻烦请教一下,查看video设备的话,其实Core-1126-JD4核心板会显示如下两个video设备.
我目前用的是video8, 请教一下和video9 有什么区别?

  1. $ v4l2-ctl --list-devices
  2. v4l2-ctlUVC: UVC Camera (usb-0000:00:14.0-2):
  3.         /dev/video8
  4.         /dev/video9
  5.         /dev/media1

  7. $ v4l2-ctl -d /dev/video8 --list-formats
  8. v4l2-ctlioctl: VIDIOC_ENUM_FMT
  9.         Type: Video Capture

  11.         [0]: 'YUYV' (YUYV 4:2:2)
  12.         [1]: 'MJPG' (Motion-JPEG, compressed)
  13.         [2]: 'H264' (H.264, compressed)
  14.         [3]: '' (35363248-0000-0010-8000-00aa003, compressed)

  16. $ v4l2-ctl -d /dev/video9 --list-formats
  17. v4l2-ctlioctl: VIDIOC_ENUM_FMT
  18.         Type: Video Capture

一个是图像/视频采集，一个是metadata采集。
可以看下这个帖子：https://forum.ubuntu.org.cn/viewtopic.php?t=490552
