本文介绍了在Android上实现虚拟摄像头的方案,主要采用v4l2loopback。通过生成video节点并写入自定义内容,应用端可访问展示。详细说明了v4l2loopback源码下载编译、v4l2-ctl编译使用及yuv420_infiniteloop测试文件编译。
详细的内容可以参考官网http://v4l.videotechnology.com/dwg/下面介绍的只是一个使用的demo,demo代码可参考https://github.com/yizhongliu/AnV4L2Camera V4L2 采集camera数据 下面是应用利用V4L2 采集camera数据的大体流程: v4l2camera.png 打开文件描述符
