视频网站中提供的在线视频播放功能,播放的都是FLV格式的文件,它是Flash动画文件,可通过Flash 制作的播放器来播放该文件.项目中用制作的播放器.多媒体视频处理工具FFmpeg有非常强大的功能包括视频采集功能、视频格式转换、视频抓图、给视频加水印等。

??ffmpeg视频采集功能非常强大，不仅可以采集视频采集卡或USB摄像头的图像，还可以进行屏幕录制，同时还支持以RTP方式将视频流传送给支持RTSP的流媒体服务器，支持直播应用。

1.能支持的格式ffmpeg能解析的格式：（asx，asf，mpg，wmv，3gp，mp4，mov，avi，flv等）2.不能支持的格式对ffmpeg无法解析的文件格式(wmv9，rm，rmvb等),可以先用别的工具（mencoder）转换为avi(ffmpeg 能解析的)格式.实例是将上传视频转码为flv格式,该格式ffmpeg支持,所以我们实例中需要ffmpeg视频处理工具.数据库实例所需要的数据库脚本drop database if exists db_mediaplayer;create database db_mediaplayer;use db_mediaplayer; create table tb_media(id int not null primary key auto_increment comment '主键' ,title varchar(50) not null comment '视频名称' ,src varchar(200) not null comment '视频存放地址' ,picture varchar(200) not null comment '视频截图' ,descript varchar(400) comment '视频描述' ,uptime varchar(40) comment '上传时间');desc tb_media;项目结构图:上传视频界面设计在上传文件时,Form表单中?enctype属性值必须为"multipart/form-data".模块界面设计如下图:enctype属性值说明application/x-www-form-urlencoded表单数据被编码为名称/值对,这是标准的编码格式multipart/form-data表单数据被编码为一条消息,页面上每个控件对应消息中的一部分text/plain表单数据以纯文本形式进行编码,其中不含任何控件格式的字符业务接口定义面向接口编程,接口中定义系统功能模块.这样方便理清业务,同时接口的对象必须由实现了该接口的对象来创建.这样就避免编码中的某些业务遗漏等,同时扩展性也增强了.packageimportimport/****** @version：** @author** @since：创建时间: 2013-2-07 上午10:19:54** TODO : interface is used for ...**/public interface MediaDao {/*** 视频转码* @param ffmpegPath 转码工具的存放路径* @param upFilePath 用于指定要转换格式的文件,要截图的视频源文件* @param codcFilePath 格式转换后的的文件保存路径* @param mediaPicPath 截图保存路径* @return* @throws Exception*/public boolean executeCodecs(String ffmpegPath,String upFilePath, String codcFilePath, String mediaPicPath)throws Exception;/*** 保存文件* @param media* @return* @throws Exception*/public boolean saveMedia(Media media)throws Exception;/*** 查询本地库中所有记录的数目* @return* @throws Exception*/public int getAllMediaCount()throws Exception;/*** 带分页的查询* @param firstResult* @param maxResult* @return*/public List<Media> queryALlMedia(int firstResult, int maxResult)throws Exception;/*** 根据Id查询视频* @param id* @return* @throws Exception*/public Media queryMediaById(int id)throws Exception;}接口的实现,这里列出ffmpeg视频转码与截图模块/*** 视频转码* @param ffmpegPath 转码工具的存放路径* @param upFilePath 用于指定要转换格式的文件,要截图的视频源文件* @param codcFilePath 格式转换后的的文件保存路径* @param mediaPicPath 截图保存路径* @return* @throws Exception*/public boolean executeCodecs(String ffmpegPath, String upFilePath, String codcFilePath,String mediaPicPath) throws Exception {因为如果对象new太多,会不必要的浪费资源.所以工厂,采用单例模式,私有构造,提供对外可访问的方法即可.packageimport/****** @version：** @author** @since：创建时间: 2013-2-07 下午02:18:51** TODO : class is used for ...**/public class DaoFactory { ervlet控制器相关代码如下packageimportimportimportimportimportimportimportimportimportimportimportimportimportimportimportimport/****** @version：** @author** @since：创建时间: 2013-2-08 下午02:24:47** TODO : class is used for ...**/public class MediaService extends HttpServlet {public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {doPost(request, response);}public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {PrintWriter out = ();MediaDao mediaDao = ();String message = "";String uri = ();String path = ("/"), ("."));if("/uploadFile".equals(path)){etBytes("ISO8859-1"),"UTF-8"));}if("descript")){(new String().getBytes("ISO8859-1"),"UTF-8"));}}else{);

片为视频转码过程中拉取到的图片.点击图片即可发送播放视频请求,视频播放页面效果如下图所示.视频播放页面需要在页面中嵌入Flash播放器代码如下:<!-- 嵌入Flash播放器 --><td align="center" width="455"><param name="movie"value="<%=basePath%>tools/=<%=basePath%><%=()%>" /><embedsrc="<%=basePath%>tools/=<%=basePath%><%=()%>"width="98%" height="90%"></embed></object></td>相关说明:<param>元素,value属性指定被加载的视频文件.实例中用的是flash制作的视频播放器.在value属性值中向播放器传递了一个file参数.该参数指定了要播放的视频的路径.<embed>元素,src属性也是用来加载影片,与<param>标记的value属性值具体相同的功能.转载请注明出处:[]。

java实现⽂件上传功能本⽂实例为⼤家分享了java实现⽂件上传的具体代码，供⼤家参考，具体内容如下⼀、⽂件上传准备⼯作对于⽂件上传，浏览器在上传的过程中将⽂件以流的形式提交到服务器。

可以选择apache的commons-fileupload包作为⽂件上传组件，commons-fileupload包依赖于commons-io包。

可以在Maven导⼊该commons-fileupload包，Maven会帮我们导⼊依赖的jar包commons-io。

<dependency><groupId>commons-fileupload</groupId><artifactId>commons-fileupload</artifactId><version>1.3.3</version></dependency>⼆、⽂件上传的主要步骤创建diskFileItemFactory对象，处理⽂件上传路径或者⼤⼩限制通过diskFileItemFactory对象作为ServletFileUpload类的参数，创建ServletFileUpload对象处理上传的⽂件三、代码实现在⽂件上传时，表单⼀定要加enctype=“multipart/form-data” 。

只有使⽤enctype=“multipart/form-data”,表单才会把⽂件的内容编码到HTML请求中。

默认enctype=“application/x-www-form-urlencoded”，表单的内容会按URL规则编码。

⽽enctype="multipart/form-data"不对字符编码。

在使⽤包含⽂件上传控件的表单时，必须使⽤该值。

method也⼀定要使⽤post请求。

<form action="/file.do" enctype="multipart/form-data" method="post"><p>上传⽤户:<input type="text" name="username"></p><p><input type="file" name="file1"></p><p><input type="file" name="file2"></p><p><input type="submit">|<input type="reset"></p></form>protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {//判断上传的是普通表单还是带⽂件的表单if (!ServletFileUpload.isMultipartContent(req)) {return;}//创建上传⽂件保存的地址，⼀般创建在WEB-INF⽬录下，⽤户⽆法直接访问该⽬录下的⽂件String uploadPath = this.getServletContext().getRealPath("/WEB-INF/upload");File uploadFile = new File(uploadPath);//如果⽂件夹不存在，则创建⼀个if (!uploadFile.exists()) {uploadFile.mkdir();}//创建上传⼤⽂件的临时地址，⼀般⼏天后⾃动删除，⽤户可以⼿动删除或者转为永久⽂件// ⼀般创建在WEB-INF⽬录下，⽤户⽆法直接访问该⽬录下的⽂件String tempPath = this.getServletContext().getRealPath("/WEB-INF/temp");File tempFile = new File(tempPath);//如果⽂件夹不存在，则创建⼀个if (!tempFile.exists()) {tempFile.mkdir();}//1.创建diskFileItemFactory对象，处理⽂件上传路径或者⼤⼩限制DiskFileItemFactory factory = getDiskFileItemFactory(tempFile);//2.获取ServletFileUploadServletFileUpload upload = getServletFileUpload(factory);//3.处理上传的⽂件try {String msg = uploadParseRequest(upload, req, uploadPath);//转发req.setAttribute("msg",msg);req.getRequestDispatcher("info.jsp").forward(req, resp);} catch (FileUploadException e) {e.printStackTrace();}}public DiskFileItemFactory getDiskFileItemFactory(File file) {DiskFileItemFactory factory = new DiskFileItemFactory();//创建⼀个缓存区，当上传⽂件⼤于设置的缓存区时，将该⽂件放到临时⽬录factory.setSizeThreshold(1024 * 1024);//缓存区⼤⼩为1Mfactory.setRepository(file);//临时⽬录return factory;}public ServletFileUpload getServletFileUpload(DiskFileItemFactory factory) {ServletFileUpload upload = new ServletFileUpload(factory);//监听⽂件上传进度upload.setProgressListener(new ProgressListener() {@Overridepublic void update(long uploaded, long totalSize, int i) {System.out.println("已上传："+(uploaded*100)/totalSize+"%");}});upload.setHeaderEncoding("UTF-8");//乱码处理upload.setFileSizeMax(1024 * 1024 * 10);//设置单个⽂件的最⼤值10Mupload.setSizeMax(1024 * 1024 * 100);//设置总共能上传⽂件的最⼤值100Mreturn upload;}public String uploadParseRequest(ServletFileUpload upload, HttpServletRequest req, String uploadPath) throws FileUploadException, IOException { String msg = "";//把前端请求解析，封装成⼀个List对象List<FileItem> fileItems = upload.parseRequest(req);for (FileItem fileItem : fileItems) {if (fileItem.isFormField()) {//判断上传的⽂件是普通的表单还是带⽂件的表单String name = fileItem.getName();//前端表单控件的name：usernameString value = fileItem.getString("UTF-8");//乱码处理System.out.println(name + ":" + value);} else {//判断为上传的⽂件//==================处理⽂件=====================String uploadFileName = fileItem.getName();//前端表单控件的nameSystem.out.println("上传的⽂件名:" + uploadFileName);if (uploadFileName.trim().equals("") || uploadFileName == null) {//可能存在不合法的情况continue;}String fileName = uploadFileName.substring(stIndexOf("/") + 1);//⽂件名String fileExtName = uploadFileName.substring(stIndexOf(".") + 1);//⽂件后缀名System.out.println("⽂件名：" + fileName + "--⽂件后缀：" + fileExtName);//==================存放地址==================String uuidPath = UUID.randomUUID().toString();//⽂件存储的真实路径String realPath = uploadPath + "/" + uuidPath;System.out.println("⽂件上传到的位置:"+realPath);//给每个⽂件创建⼀个⽂件夹File realPathFile = new File(realPath);if (!realPathFile.exists()) {//如果⽂件夹不存在，则创建⼀个realPathFile.mkdir();}//==================⽂件传输==================//获得⽂件上传的流InputStream inputStream = fileItem.getInputStream();//创建⼀个⽂件输出流FileOutputStream fileOutputStream = new FileOutputStream(realPath + "/" + fileName);//创建⼀个缓冲区byte[] buffer = new byte[1024 * 1024];//判断读取是否完毕int len = 0;while ((len = inputStream.read(buffer)) > 0) {fileOutputStream.write(buffer, 0, len);}//关闭流fileOutputStream.close();inputStream.close();msg = "上传成功";fileItem.delete();//上传成功，清除临时⽂件}}return msg;}⽂件上传的注意事项1、为保证服务器安全，上传的⽂件应该放在外界⽆法直接访问的⽬录下，例如放在WEB-INF⽬录下。

java,单⽂件和多⽂件上传代码范例上传⼀个单⽂件，⽤request.getFile得到⽂件（下⾯的功能是上传到阿⾥云）@RequestMapping(value = {"/content"}, method = RequestMethod.POST, headers = "content-type=multipart/form-data") public String content(ModelMap modelMap,MultipartHttpServletRequest request,HttpServletResponse response){response.setHeader("Access-Control-Allow-Origin", "*");OSSUpload ossUpload = new OSSUpload("xinmeiti");Iterator<String> itr = request.getFileNames();MultipartFile file = request.getFile(itr.next());Map<String, Object> map = new HashMap<>();try{byte[] bytes = org.apache.poi.util.IOUtils.toByteArray(file.getInputStream());String fileType = getImageType(bytes);String md5 = StringUtils.md5(String.valueOf(bytes));String fileName = firstName +"/"+md5 + "."+ fileType;Map<String, Object> uploadResult = ossUpload.upload(bytes, fileName);if(!uploadResult.get("status").equals(0)){modelMap.addAttribute("json", StringUtils.toJson(uploadResult));}else{map.put("url", cndName+fileName);modelMap.addAttribute("json", StringUtils.toJson(map));}} catch (IOException e) {modelMap.addAttribute("json", StringUtils.toJson(new ReturnMap(10004, "上传图⽚失败")));e.printStackTrace();}return "mis/json";}上传多个⽂件，⽤request.getFile得到多⽂件@RequestMapping(value = {"multipleFileUpload"}, method = {RequestMethod.GET, RequestMethod.POST})public String multipleFileUpload(ModelMap modelMap,MultipartHttpServletRequest request,HttpServletResponse response,@RequestParam(value = "type") String type,@RequestParam(value = "jobId") String jobId) throws IOException {List < MultipartFile > files = request.getFiles("files");response.setHeader("Access-Control-Allow-Origin", "");Map<String, Object> statusMap = new HashMap<>();HttpSession session = request.getSession();session.setAttribute("gifCompressStatus", statusMap);int compressSize = getCompressSizeByValue(type);for(MultipartFile file :files){String filename = file.getOriginalFilename().split(".gif")[0];Map<String, Object> resultMap = new HashMap<>();resultMap.put("size" , 0);resultMap.put("status" , 0);resultMap.put("url" , "");statusMap.put(filename, resultMap);InputStream is = file.getInputStream();byte[] bytes = IOUtils.toByteArray(is);CompressWorker worker = new CompressWorker(statusMap, bytes, filename, compressSize, jobId);worker.start();}modelMap.addAttribute("json", StringUtils.toInsensitiveJson(new ReturnMap("线程已启动")));return "json";}在使⽤MultipartHttpServletRequest类型的时候需要注意，随便什么request都是MultipartHttpServletRequest在这⾥举两个可以⽤MultipartHttpServletRequest的例⼦。
