4.2.1 全编译测试

在源码路径内,提供了编译脚本 build.sh,运行该脚本对整个源码进行编译,需要在终端切换到解压

出来的源码路径,找到 build.sh 文件。

forlinx@ubuntu:~$ cd /home/forlinx/3588/OK3588_Linux_fs

以下操作需要在源码目录下操作,全编译方法:

1、生成编译所需配置(此时需要 forlinx 用户密码,密码也是 forlinx)

forlinx@ubuntu: ~/3588/OK3588_Linux_fs$ sudo ./build.sh BoardConfig-linuxfs-ok3588.mk

2、进行全编译

forlinx@ubuntu: ~/3588/OK3588_Linux_fs$ sudo ./build.sh

编译成功后,使系统镜像将在 rockdev 文件夹下生成,如下图:

4.2.2 单独编译

用户在内核源码路径下进行操作。

forlinx@ubuntu: ~/3588/OK3588_Linux_fs$ sudo ./build.sh kernel

v4l2-ctl --list-devices

v4l2-ctl --list-formats-ext -d /dev/video0

抖动

录像时在HDMI OUT可以预览
gst-launch-1.0 v4l2src device=/dev/video0 num-buffers=100000 ! video/x-raw,format=NV12, width=1920,height=1080 ! tee name=t ! queue ! mpph264enc ! queue ! h264parse ! qtmux ! filesink location=fpga10000-9500.mp4 t. ! queue ! waylandsink

在HDMI OUT预览时不要保存mp4文件

在HDMI OUT预览时,帧数也不要了!
