FFmpeg is probably the best choice. It has a wide-range of formats, flexibility and codec support. There's little comparison. There are a variety of desktop apps that are built on it too, if you need a UI.
I'm a huge fan of ffmpeg. Find out what codec and resolution your mobile device wants. If you're lucky, H.264 will be supported. That codec seems to produce excellent compression these days.
Crazy thing I found the other day. I used QuickTime to File->Export->iPhone my 250MB .avi file and it output the file into four new/different files. Three were in .m4v format and varied in size from 62.3MB to 6.8MB. However the fourth file was a .mov file that was only 381 bytes in size. You read that right. It compressed the video from 250MB to 381b or <1KB. If my math serves me right that is over 600K times smaller than the original file.

FFmpeg 可能是最好的选择。 它具有广泛的格式、灵活性和编解码器支持。 没什么可比性。 如果您需要 UI，也可以在其上构建各种桌面应用程序。

如果您正在寻找一个应用程序super (c) 非常擅长各种视频压缩虽然它有一个非常奇怪的用户界面
if you are looking for an application super (c) is very good at all sort of video compressions tho it has a pretty weird UI
我是 ffmpeg 的忠实粉丝。 了解您的移动设备需要什么编解码器和分辨率。 如果幸运的话，将支持 H.264。 如今，该编解码器似乎可以产生出色的压缩效果。

前几天我发现了一件疯狂的事情。 我使用 QuickTime 来“文件”->“导出”->iPhone 我的 250MB .avi 文件，并将该文件输出到四个新的/不同的文件中。 其中三个采用 .m4v 格式，大小从 62.3MB 到 6.8MB 不等。 然而，第四个文件是一个 .mov 文件，大小仅为 381 字节。 你没看错。 它将视频从 250MB 压缩到 381b 或 <1KB。 如果我的数学正确的话，它比原始文件小 600K 倍以上。
仅供参考。 希望这可以帮助。

Just fyi. Hope this helps.
