FFmpeg视频录制压缩处理走过的坑
来源：互联网 发布：微网站模板源码下载 编辑：程序博客网 时间：2024/05/16 09:31
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。

} } 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); }}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
这个便是处理视频压缩，时长等等功能的代码部分
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
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：
