window可以直接放在项目中但是linux还需要配置。步骤如下。
1、将上方的linux包上传到服务器解压缩:
tar -xvf ffmpeg-release-amd64-static.tar.xz
2、解压缩后进入根目录分别复制根目录下的ffmpeg和ffprobe到 /usr/local/bin/目录下:
sudo cp 解压缩目录/ffmpeg /usr/local/bin/ sudo cp 解压缩目录/ffprobe /usr/local/bin/
3.还要给文件设置权限否则运行代码的时候报没有权限:
sudo chmod x /usr/local/bin/ffmpeg
sudo chmod x /usr/local/bin/ffprobe
4、最后检查是否配置成功,如果有内容输出来则成功
ffmpeg -version
ffprobe -version
linux环境配置好后即可正常解析.

由于视频转换下载等速度比较慢推荐使用异步执行。我用的是若依的框架代码如下。如用其他框架可自行参考写异步操作
//异步执行方法。不会等待执行完才执行下一位
AsyncManager.me().execute(AsyncFactory.convertVideoNetUrl(video.getVideoPath(),video.getId(),Constants.CONVERT_VIDEO_NET_VIDEO_URL));#在AsyncManager类里自定义一个异步方法如下/*** * param videNetUrl 视频网络地址* param id 类id* param entityClazz 类 0视频 1文章* return 任务task*/public static TimerTask convertVideoNetUrl(final String videNetUrl,Long id,Integer entityClazz){return new TimerTask(){Overridepublic void run(){if (entityClazz null || id null || StrUtil.isBlank(videNetUrl)){return;}if (entityClazz 0){IVideoService videoService SpringUtils.getBean(IVideoService.class);Video video videoService.selectVideoById(id);if (video null){return;}//现在是上传视频地址//先转换视频地址到服务器//后缀String ext video.getVideoPath().substring(video.getVideoPath().lastIndexOf(.));String videosubpath StringUtils.format({}/{}_{}{}, DateUtils.datePath(),IdUtils.fastSimpleUUID(), Seq.getId(Seq.uploadSeqType), ext);String downloadPath null;try {downloadPath FileUploadUtils.getAbsoluteFile(HqaConfig.getUploadPath() /, videosubpath).getAbsolutePath();}catch (Exception e){e.printStackTrace();}boolean downVideo VideoCovertUtil.downVideo(video.getVideoPath(),downloadPath);if (downVideo StrUtil.isNotBlank(downloadPath) downloadPath ! null){if (!ext.contains(mp4)){//下载成功后如果不是mp4格式转换成mp4格式String newVideosubpath StringUtils.format({}/{}_{}{}, DateUtils.datePath(),IdUtils.fastSimpleUUID(), Seq.getId(Seq.uploadSeqType), .mp4);String newMp4FilePath null;try {newMp4FilePath FileUploadUtils.getAbsoluteFile(HqaConfig.getUploadPath() /, newVideosubpath).getAbsolutePath();}catch (Exception e){e.printStackTrace();}boolean toMp4 VideoCovertUtil.otherVideoToMp4(downloadPath,newMp4FilePath);if (toMp4 StrUtil.isNotBlank(newMp4FilePath) newMp4FilePath ! null){//转换成功后删除之前下载过的视频地址并且保存新的mp4地址if (new File(downloadPath).exists()){FileUtils.deleteFile(downloadPath);}if (newMp4FilePath.contains(\\)){newMp4FilePath newMp4FilePath.replace(\\,/);}String newPath newMp4FilePath.replace(HqaConfig.getProfile(),/profile);video.setVideoPath(newPath);}}else{if (downloadPath.contains(\\)){downloadPath downloadPath.replace(\\,/);}//保存地址String newPath downloadPath.replace(HqaConfig.getProfile(),/profile);video.setVideoPath(newPath);}//视频截图和时长//获取视频第一帧封面String parentPath HqaConfig.getUploadPath()/ DateUtils.datePath();String fileName IdUtils.fastSimpleUUID().png;String targetPath parentPath/ fileName;try {FileUploadUtils.getAbsoluteFile(parentPath,fileName);} catch (IOException e) {e.printStackTrace();}String filePath video.getVideoPath().replace(/profile,);filePathHqaConfig.getProfile()filePath;VideoCovertUtil.getCover(filePath,targetPath);video.setCover(targetPath.replace(HqaConfig.getProfile(),/profile));String duration VideoCovertUtil.getDuration(filePath);video.setDuration(duration);videoService.updateVideo(video);}}else if (entityClazz 1){IArticleService articleService SpringUtils.getBean(IArticleService.class);Article article articleService.selectArticleById(id);if (article null){return;}//现在是上传视频地址//先转换视频地址到服务器//后缀String ext article.getVideoPath().substring(article.getVideoPath().lastIndexOf(.));String videosubpath StringUtils.format({}/{}_{}{}, DateUtils.datePath(),IdUtils.fastSimpleUUID(), Seq.getId(Seq.uploadSeqType), ext);String downloadPath null;try {downloadPath FileUploadUtils.getAbsoluteFile(HqaConfig.getUploadPath() /, videosubpath).getAbsolutePath();}catch (Exception e){e.printStackTrace();}boolean downVideo VideoCovertUtil.downVideo(article.getVideoPath(),downloadPath);if (downVideo StrUtil.isNotBlank(downloadPath) downloadPath ! null){if (!ext.contains(mp4)){//下载成功后如果不是mp4格式转换成mp4格式String newVideosubpath StringUtils.format({}/{}_{}{}, DateUtils.datePath(),IdUtils.fastSimpleUUID(), Seq.getId(Seq.uploadSeqType), .mp4);String newMp4FilePath null;try {newMp4FilePath FileUploadUtils.getAbsoluteFile(HqaConfig.getUploadPath() /, newVideosubpath).getAbsolutePath();}catch (Exception e){e.printStackTrace();}boolean toMp4 VideoCovertUtil.otherVideoToMp4(downloadPath,newMp4FilePath);if (toMp4 StrUtil.isNotBlank(newMp4FilePath) newMp4FilePath ! null){//转换成功后删除之前下载过的视频地址并且保存新的mp4地址if (new File(downloadPath).exists()){FileUtils.deleteFile(downloadPath);}if (newMp4FilePath.contains(\\)){newMp4FilePath newMp4FilePath.replace(\\,/);}String newPath newMp4FilePath.replace(HqaConfig.getProfile(),/profile);article.setVideoPath(newPath);}}else{if (downloadPath.contains(\\)){downloadPath downloadPath.replace(\\,/);}//保存地址String newPath downloadPath.replace(HqaConfig.getProfile(),/profile);article.setVideoPath(newPath);}articleService.updateArticle(article);}}}};}
