怎么，没人回帖啊，以下是我在stackoverflow搜的资料，使用了别人的代码，感觉代码导出视频效率低！ http://stackoverflow.com/questions/9334062/recommended-java-library-for-creating-a-video-programmatically http://www.randelshofer.ch/blog/2010/10/writing-quicktime-movies-in-pure-java/Question: Can anyone recommend a Java library that would allow me to create a video programmatically? Specifically, it would do the following: take a series of BufferedImages as the frames allow a background WAV/MP3 to be added allow 'incidental' WAV/MP3s to be added at arbitrarily, programmatically specified points output the video in a common format (MPEG etc) Can anybody recommend anything? For the picture/sound mixing, I'd even live with something that took a series of frames, and for each frame I had to supply the raw bytes of uncompressed sound data associated with that frame. P.S. It doesn't even have to be a "third party library" as such if the Java Media Framework has the calls to achieve the above, but from my sketchy memory I have a feeling it doesn't.Answer: I've used the code mentioned below to successfully perform items 1, 2, and 4 on your requirements list in pure Java. It's worth a look and you could probably figure out how to include #3. http://www.randelshofer.ch/blog/2010/10/writing-quicktime-movies-in-pure-java/I found a tool called ffmpeg which can convert multimedia files form one format to another. There is a filter called libavfilter in ffmpeg which is the substitute for vhook which allows the video/audio to be modified or examined between the decoder and the encoder. I think it should be possible to input raw frames and generate video. I researched on any java implementation of ffmpeg and found the page titled"Getting Started with FFMPEG-JAVA" which is a JAVA wrapper around FFMPEG using JNA. Why not use FFMPEG? There seems to be a Java wrapper for it: http://fmj-sf.net/ffmpeg-java/getting_started.php Here is an example of how to compile various media sources into one video with FFMPEG: http://howto-pages.org/ffmpeg/#multiple And, finally, the docs: http://ffmpeg.org/ffmpeg.html
