本帖最后由 ubuntu 于 2021-7-22 16:25 编辑参考官方文档Rockchip_Instruction_Linux_Application_ISP20_CN.pdf 2.1节。
成功build 如下程序push 后
external/rkmedia/examples/unitTest/stream/camera_capture_test.cc
执行如下程序失败， video19 在我设备上是isppscale0， 执行过程如下， 会产生一个size为0的out.yuv
<div class="blockcode"><blockquote># camera_cap_test -i /dev/video19 -o /tmp/outpu

cd /oem;./RkLunch-stop.sh 之后再运行看看效果
