现在Html5也逐渐普及了，设备对于mp4/webm/ogv的支持也逐渐广泛，但是Html5视频的转换软件却不是太多，这个Ffmpeg确实不错。而且功能也强大。

HTML5先网页直接打开mp4 如果打不开 先用格式工厂转化下格式 转成标准mp4 就行了

讯捷视频转换器也可以

遍历目录下的所有mpg文件，挨个转换到该目录！

1	for/r%1%%iin (*.mpg)do "D:\Program Files\FFmpeg\Convert.bat"%%i

代码很简单，但是很实用，如果文件格式太乱，可以使用文件列表的形式来进行

1	for/r%1%%iin (list.txt)do "D:\Program Files\FFmpeg\Convert.bat"%%i

大概就这些了，更多方法可以查看FFmpeg的使用说明
