三、SDK配置

source build/envsetup.sh 和 lunch 之后可以使用 quick_config 的 one_gc2083_sensor 来启用摄像头GC2083，也可以参考以下设备树配置

然后在mpp启动rtsp，拷贝执行文件和配置文件到sd卡上

四、测试

4-1 启动信息

4-2 iic节点

root@TinaLinux:~# i2cdetect -y 00  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:          -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- UU -- -- -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --

4-3 rtsp推流

在 /mnt/extsd 目录下

./sample_rtsp -path ./sample_rtsp.conf

如果使用wlan0的话要先把配置改一下

########### paramter (ref to tulip_cedarx.conf)############
[parameter]rtsp_net_type = 3                      #RTSP Network type, 0: "lo", 1: "eth0", 2: "br0", 3: "wlan0"

程序正常运行，出现rtsp链接

4-3 rtsp拉流

winddows下安装 VLC media player

然后就可以看到设备的视频流

4-3-1 ch1

在这里我打开的是ch1，分辨率较低，只有 640x360

4-3-1 ch0

然后我们使用ch0，很明显已经清晰很多，分辨率为1280x720
