你好覆盆子的人!
我发布了一个新问题,因为我在raspberrypi.stackexchange上没有足够的代表才能对此帖子发表评论:https : //raspberrypi.stackexchange.com/questions/15000/stream-video-from-rpi-cam -to-android-phone可以解决我的问题,只有我无法使它起作用:(
简而言之,我想通过我的Android控制机器人,机器人内部是带有树莓派相机的树莓派。因此,对于初学者来说,我只想将视频从机器人流式传输到手机上的Java应用程序。
。
关于上述问题的第一条评论链接到该帖子,该帖子显示了如何使用PS眼睛作为摄像头将视频从Raspberry流式传输到Android手机。
“ alex”的第四个评论说,关于使用树莓派pi摄像头而不是PS摄像头摄像头:
I've found the solution: I had to install the uv4l driver
to use the RaspiCam as /dev/video0 and I had to modify the gst-server.sh :
inserted videoscale !\ after ffmpegcolorspace !\ and it works :)
因此, 我按照本指南在树莓派上安装uv4l驱动程序:http : //www.linux-projects.org/modules/sections/index.php? op=viewarticle&artid =14
我认为正在运行这些终端命令:
wget http://www.linux-projects.org/listing/uv4l_repo/lrkey.asc && sudo apt-key add ./lrkey.asc
Adding line to apt sources -->> deb http://www.linux-projects.org/listing/uv4l_repo/raspbian/ wheezy main
sudo apt-get update
sudo apt-get install uv4l uv4l-raspicam
sudo apt-get install uv4l-raspicam-extras
现在,如果我快速测试UV4L驱动程序
dd if=/dev/video0 of=snapshot.jpeg bs=11M count=1
我得到的只是一张全黑的快照。
另外,如果我尝试重新启动驱动程序:
sudo service uv4l_raspicam restart
我收到此警告:
pi@raspberrypi /etc/uv4l $ sudo service uv4l_raspicam restart

任何见解都将不胜感激!而且,对冗长的帖子很抱歉:(
非常感谢!
