主要用ffmpeg，將視頻拆分成一幀幀圖片，然后分別修改圖片，再重新合成視頻

斷斷續續搞了幾個月，先記錄一下。

public static void makeVideos(String videoPath,List<List<String>> txs, String srcmusic,String targetPath){String tem="c:/temspace/"+FileUtil.getFileNameWithoutSuffix(videoPath);//生成每一幀FfmpegUtil.video2Images(videoPath, tem);List<String> imgs = FileUtil.orderNameByNumber(FileUtil.getAllSubPath(tem));//修改幀數Map<String, Object> info = FfmpegUtil.getVideoInfo(videoPath);int totalframe=Integer.parseInt(info.get("totalframe").toString());int fps=Integer.parseInt(info.get("fps").toString());int newfps=fps-1;List<String> newimgs=new ArrayList<String>();for (int i = 0; i < (totalframe/fps); i++) {Map<Integer, Integer> position = VideoImageUtil.setPosition(newfps, fps);for(int key:MapUtil.orderMapKey(position)){int v=position.get(key);newimgs.add(imgs.get(i*fps+v-1));}} for (int i = (totalframe/fps)*fps; i < totalframe; i++) {newimgs.add(imgs.get(i));}imgs.removeAll(newimgs);FileUtil.delFile(imgs);FileUtil.rename_ordernum(newimgs,1);imgs = FileUtil.orderNameByNumber(FileUtil.getAllSubPath(tem));//每一幀加上特效List<Integer> idxs=new ArrayList<>();for (int i = 0; i < txs.size(); i++) {idxs.add(1);}for (int i = 0; i < imgs.size(); i++) {for (int j = 0; j < idxs.size(); j++) {if(idxs.get(j)>=txs.get(j).size()) idxs.set(j, 0);}for (int j = 0; j < txs.size(); j++) {List<String> tx = txs.get(j);ImageBorderUtil.screen(imgs.get(i), tx.get(idxs.get(j)), imgs.get(i));idxs.set(j, idxs.get(j)+1);}ImageUtil.gaussian(imgs.get(i), 0, 990, 576, 34, 20, imgs.get(i));ImageUtil.gaussian_gradual(imgs.get(i), 0, 0, 576, 30, false,20, imgs.get(i));}//生成視頻String temvideo="c:/temspace/"+System.currentTimeMillis()+".mp4";String usemusic="c:/temspace/"+System.currentTimeMillis()+".wav";boolean issrcmusic=false;FfmpegUtil.images2Video(tem, newfps,temvideo);Map<String, Object> teminfo = FfmpegUtil.getVideoInfo(temvideo);long len=1000*Long.parseLong(teminfo.get("milstimelen").toString());//視頻長度 微秒long microsecond = WavUtil.getMicrosecond(srcmusic);//音樂長度 微秒if(len>microsecond){//音樂太短，重復補足到視頻長度int time=(int) (len/microsecond);List<String> subfiles=new ArrayList<String>();for (int i = 0; i < time; i++) {subfiles.add(srcmusic);}long cutlen=len%microsecond;String temleftaudio="";if(cutlen>0){temleftaudio="c:/temspace/"+System.currentTimeMillis()+".wav";WavUtil.cut(srcmusic, temleftaudio, 0, cutlen);subfiles.add(temleftaudio);}WavUtil.mergeAudio(subfiles,usemusic);if(!"".equals(temleftaudio)) FileUtil.del(temleftaudio);}else if(len<microsecond){//音樂太長，截取WavUtil.cut(srcmusic, usemusic, 0, len);}else{usemusic=srcmusic;issrcmusic=true;}FfmpegUtil.combineVideoAndAudio(temvideo, usemusic, targetPath);FileUtil.del(temvideo);if(!issrcmusic) FileUtil.del(usemusic);FileUtil.del(tem);}
