在公司里面开发项目做视频处理时遇到了问题，这个问题困扰我很久了，解决了只想给大家说出来，虽然很简单的问题，免得你们遇到我类似的问题再次难以自拔！
视频压缩处理我用了两种方式来解决的，一种是第三方，一种用了自己写了封装的。
今天先给大家讲解popwindow引用第三方视频压缩处理所注意的问题。

List 这种方式使用压缩异常简单
第一步：
添加下面这段依赖同步
compile 'com.mabeijianxi:small-video-record:1.0.7'
第二步：
在activity或者fragment中初始化initSmallVideo()
private void initSmallVideo(Context context) {
// 设置拍摄视频缓存路径
File dcim = Environment
.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM);
if (DeviceUtils.isZte()) {
if (dcim.exists()) {
VCamera.setVideoCachePath(dcim + "/beiguanhuai/");
} else {
VCamera.setVideoCachePath(dcim.getPath().replace("/sdcard/",
"/sdcard-ext/")
+ "/beiguanhuai/");
}
} else {
VCamera.setVideoCachePath(dcim + "/beiguanhuai/");
}
// 开启log输出,ffmpeg输出到logcat
VCamera.setDebugMode(true);
// 初始化拍摄SDK，必须
VCamera.initialize(context);
}
第三步
只需要写个button就可启动
这里写图片描述
这个便是处理视频压缩，时长等等功能的代码部分
这里写图片描述
当然这样写很多人会觉得没问题的呀
我就是这么干的，加上去后代码不会 报错，而且运行正常，但是当你点击下面这个popwindow的按钮时
这里写图片描述
你会发现之前写的拍照，相册不能使用了，按钮点击无响应，万般无奈看了各种博客说什么gradle的呀，SDK版本问题的呀...........?最后还是没能解决，还真不好注意这方面的问题。
解决办法
将写好的权限管理全部注释掉使用EasyPermissions啊或者其他类的来管理动态授权，在这里面只有简单的调用就OK了
最后每个按钮的点击事件便都能响应
效果图如下：
