如何使用Xuggle将flv视频转换为Mp4格式？我需要研究哪种api方法？任何链接/指针都会有所帮助
答案 0 :(得分：7)
来自javadoc，
有多简单？以下是打开MPEG视频文件的一些代码，将其转换为Adobe Flash视频文件：
IMediaReader reader = ToolFactory.newReader("input.mpg");
reader.addListener(ToolFactory.newWriter("output.flv", reader));
while (reader.readPacket() == null)
;
此方法适用于xuggle支持的所有格式。
从this question看起来这是支持的编解码器列表
Codecs:
D..... = Decoding supported
.E.... = Encoding supported
..V... = Video codec
..A... = Audio codec
..S... = Subtitle codec
...S.. = Supports draw_horiz_band
....D. = Supports direct rendering method 1
.....T = Supports weird frame truncation

Note, the names of encoders and decoders do not always match, so there are
several cases where the above table shows encoder only or decoder only entries
even though both encoding and decoding are supported. For example, the h263
decoder corresponds to the h263 and h263p encoders, for file formats it is even
worse.
