推荐一个零声学院免费教程，个人觉得老师讲得不错， 分享给大家：[Linux，Nginx，ZeroMQ，MySQL，Redis， fastdfs，MongoDB，ZK，流媒体，CDN，P2P，K8S，Docker， TCP/IP，协程，DPDK等技术内容，点击立即学习: https://ke.qq.com/course/4032547?flowToken=1042705 前言本来是想用xawtv来测试摄像头，结果不是很喜欢，然后，就想找一个喜欢的，然后就变成摄像头软件汇总了。 一 在ubuntu虚拟机中查看拢共分三步 1.先 ls /dev/video* ls /dev/video*2. 插入外置摄像头 3.再 ls /dev/video* 多出来的那个videoXXX设备就是摄像头了。 我使用的是一个外置的USB摄像头，将USB摄像头连接到虚拟机后，使用dmesg命令，会看到usb摄像头被加载过程的信息。 [92462.307190] usb 3-2: new high-speed USB device number 5 using xhci_hcd [92462.726303] usb 3-2: New USB device found, idVendor=1e45, idProduct=3035 [92462.726306] usb 3-2: New USB device strings: Mfr=3, Product=1, SerialNumber=2 [92462.726356] usb 3-2: Product: USB Camera [92462.726357] usb 3-2: Manufacturer: Generic [92462.726358] usb 3-2: SerialNumber: 0001 [92462.857710] media: Linux media interface: v0.10 [92462.994536] Linux video capture interface: v2.00 [92463.096302] usbcore: registered new interface driver snd-usb-audio [92463.177813] uvcvideo: Found UVC 1.00 device USB Camera (1e45:3035) [92463.185183] input: USB Camera: USB Camera as /devices/pci0000:00/0000:00:15.0/0000:03:00.0/usb3/3-2/3-2:1.0/input/input6 [92463.185506] usbcore: registered new interface driver uvcvideo [92463.185507] USB Video Class driver (1.1.1) [92469.683588] usb 3-2: USB disconnect, device number 5 [92470.406837] usb 3-2: new high-speed USB device number 6 using xhci_hcd [92470.810353] usb 3-2: New USB device found, idVendor=1e45, idProduct=3035 [92470.810356] usb 3-2: New USB device strings: Mfr=3, Product=1, SerialNumber=2 [92470.810357] usb 3-2: Product: USB Camera [92470.810358] usb 3-2: Manufacturer: Generic [92470.810359] usb 3-2: SerialNumber: 0001 [92470.823773] uvcvideo: Found UVC 1.00 device USB Camera (1e45:3035) [92470.833211] input: USB Camera: USB Camera as /devices/pci0000:00/0000:00:15.0/0000:03:00.0/usb3/3-2/3-2:1.0/input/input7 [92478.499868] usb 3-2: USB disconnect, device number 6 [92479.215252] usb 3-2: new high-speed USB device number 7 using xhci_hcd [92479.614817] usb 3-2: New USB device found, idVendor=1e45, idProduct=3035 [92479.614819] usb 3-2: New USB device strings: Mfr=3, Product=1, SerialNumber=2 [92479.614820] usb 3-2: Product: USB Camera [92479.614821] usb 3-2: Manufacturer: Generic [92479.614821] usb 3-2: SerialNumber: 0001 [92479.623908] uvcvideo: Found UVC 1.00 device USB Camera (1e45:3035) [92479.629663] input: USB Camera: USB Camera as /devices/pci0000:00/0000:00:15.0/0000:03:00.0/usb3/3-2/3-2:1.0/input/input8 [92483.057036] usb 3-2: USB disconnect, device number 7 [92483.770509] usb 3-2: new high-speed USB device number 8 using xhci_hcd [92484.172011] usb 3-2: New USB device found, idVendor=1e45, idProduct=3035 [92484.172013] usb 3-2: New USB device strings: Mfr=3, Product=1, SerialNumber=2 [92484.172015] usb 3-2: Product: USB Camera [92484.172016] usb 3-2: Manufacturer: Generic [92484.172017] usb 3-2: SerialNumber: 0001 [92484.181008] uvcvideo: Found UVC 1.00 device USB Camera (1e45:3035) [92484.189816] input: USB Camera: USB Camera as /devices/pci0000:00/0000:00:15.0/0000:03:00.0/usb3/3-2/3-2:1.0/input/input9 [92484.551272] usb 3-2: USB disconnect, device number 8 [92485.262678] usb 3-2: new high-speed USB device number 9 using xhci_hcd [92485.660855] usb 3-2: New USB device found, idVendor=1e45, idProduct=3035 [92485.660857] usb 3-2: New USB device strings: Mfr=3, Product=1, SerialNumber=2 [92485.660858] usb 3-2: Product: USB Camera [92485.660859] usb 3-2: Manufacturer: Generic [92485.660859] usb 3-2: SerialNumber: 0001 [92485.670919] uvcvideo: Found UVC 1.00 device USB Camera (1e45:3035) [92485.678017] input: USB Camera: USB Camera as /devices/pci0000:00/0000:00:15.0/0000:03:00.0/usb3/3-2/3-2:1.0/input/input10查看设备名: $ ls /dev/video* -ls 0 crw-rw----+ 1 root video 81, 0 9月 16 11:55 /dev/video0当前/dev目录中多出了一个video0设备，主设备号是81，次设备号是0 二 xawtv测试
点击OK，邮件点击视频窗口，看到Options窗口。
(⊙o⊙)…好像我的需求中不需要窗口 看看帮助信息: xawtv -h lkmao@ubuntu:~$ xawtv -h This is xawtv-3.103, running on Linux/x86_64 (4.15.0-142-generic) usage: xawtv [ options ] [ station ] options: -h -help print this text -v -debug n debug level n, n = [0..2] -remote assume remote display -n -noconf don't read the config file -m -nomouse startup with mouse pointer disabled -f -fullscreen startup in fullscreen mode -(no)dga enable/disable DGA extension -(no)vm enable/disable VidMode extension -(no)randr enable/disable Xrandr extension -(no)xv enable/disable Xvideo extension altogether -(no)xv-video enable/disable Xvideo extension (for video only, i.e. XvPutVideo() calls) -(no)xv-image enable/disable Xvideo extension (for image scaling only, i.e. XvPutImage() calls) -(no)gl enable/disable OpenGL -(no)alsa enable/disable alsa streaming.

看一下帮助信息: lkmao@ubuntu:~$ cheese -h 用法： cheese [选项...] 帮助选项： -h, --help 显示帮助选项 --help-all 显示全部帮助选项 --help-gapplication 显示 GApplication 选项 --help-gtk 显示 GTK+ 选项 应用程序选项： -w, --wide 以宽屏模式启动 -d, --device=设备 用作摄像头的设备 -v, --version 输出版本信息并退出 -f, --fullscreen 以全屏模式启动 --display=显示 要使用的 X 显示 lkmao@ubuntu:~$看一下就好了，再换一个 四 camorama测试这个没用过，得先安装 sudo apt install camorama这个东西好像支持FTP远程访问
下面的尝试不一定成功啊，试一下，将摄像头连接到另一个虚拟机中，取名虚拟机2号，小名虚2。并保证该虚拟机安装了ftp服务器。(⊙o⊙)…，没安装。那就安装吧，过程在本文下面。 在虚1中运行camorama，然后配置FTP，这个时候虚1中已经没有摄像头了，因为连接到虚2上了，打开会报错，如下所示，所以要看看帮助信息
先在虚1中连接笔记本电脑的摄像头。保证camorama能打开 配置如下所示:
点击take picture,报错。
不知道怎么弄了，暂时先换一个软件。 ubuntu中使用guvcview sudo apt install guvcview直接运行guvcview即可
运行 $ mplayer mplayer: error while loading shared libraries: libfaad.so.2: cannot open shared object file: No such file or directory $这个没安装成功 $ sudo apt install mencoder Reading package lists... Done Building dependency tree... Done Reading state information... Done You might want to run 'apt --fix-broken install' to correct these. The following packages have unmet dependencies: mencoder : Depends: libfaad2 (>= 2.7) but it is not going to be installed mplayer : Depends: libfaad2 (>= 2.7) but it is not going to be installed E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution). $为了解决了这个问题，又单独写了一篇文章，这篇文章介绍了faad源码下载与编译安装。安装完以后mplayer就可以使用了。 https://lkmao.blog.csdn.net/article/details/126952445 五 在ubuntu中测试luvcview安装依赖包 sudo apt-get install debhelper sudo apt-get install libsdl1.2-dev sudo apt-get install libv4l-dev sudo apt-get install pkg-config下载的0.2.6版本的源码，make会报错，将其中的会报错文件中的 #include 替换成#include 只需要修改三个文件就行了，编译好的源码，在我的下载资源中有。地址： https://download.csdn.net/download/yueni_zhao/86544123?spm=1001.2014.3001.5501 编译完毕后生成luvcview可执行文件 ./luvcview如果找不到摄像头会出书如下内容: $ ./luvcview luvcview 0.2.6 SDL information: Video driver: x11 A window manager is available Device information: Device path: /dev/video0 ERROR opening V4L interface: No such file or directory如果有摄像头，输出如下内容: $ ./luvcview luvcview 0.2.6 SDL information: Video driver: x11 A window manager is available Device information: Device path: /dev/video0 Stream settings: Frame format: MJPG Frame size: 640x480 Frame rate: 30 fps 在虚拟机中安装FTP服务器 打开 Ubuntu 的终端窗口，然后执行如下命令来安装 FTP 服务： sudo apt-get install vsftpd lkmao@ubuntu:~$ sudo apt-get install vsftpd [sudo] password for lkmao: E: Could not get lock /var/lib/dpkg/lock-frontend - open (11: Resource temporarily unavailable) E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it? lkmao@ubuntu:~$安装器被锁住了，这都是自动更新的锅。将自动更新设置为never。然后重启
重启后，开始安装，等待软件安装完成，完成以后使用 VI 命令打开/etc/vsftpd.conf，命令如下： sudo vi /etc/vsftpd.conf打开 vsftpd.conf 文件以后找到如下两行： local_enable=YES write_enable=YES 确保上面两行前面没有“#”，有的话就取消掉，完成以后如图 4.1.1 所示：
修改完
vsftpd.conf
以后保存退出，使用如下命令重启
FTP
服务：
sudo /etc/init.d/vsftpd restart
