官方源码链接：v4l-utils
参考：链接

编译过程：

source /opt/fsl-imx-wayland/6.1-mickledore/environment-setup-armv8a-poky-linux
export CFLAGS="--sysroot=/opt/fsl-imx-wayland/6.1-mickledore/sysroots/armv8a-poky-linux/ -Wall -Ilib/include"
wget http://linuxtv.org/downloads/v4l-utils/v4l-utils-1.26.1.tar.bz2
tar xvfj v4l-utils-1.24.1.tar.bz2
cd v4l-utils-1.24.1
./configure --target=aarch64-poky-linux --host=aarch64-poky-linux --build=x86_64-linux
make -j 24

编译结果：
需要找下，在./utils/v4l2-ctl/.libs/v4l2-ctl 和 ./utils/media-ctl
以及需要lib库也要复制到/lib下。
