注意:
若安装过程中出现以下错误:
yasm/nasm not found or too old. Use –disable-yasm for a crippled build.
If you think configure made a mistake, make sure you are using the latest
version from Git. If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file “config.log” produced by configure as this will help
solve the problem.
需要安装 yasm

最后测试:
首先由一个avi格式的视频文件,大小是37M,现在使用ffmpeg转换为mp4格式,执行下面命令:ffmpeg -i test.avi out.mp4
确认之后,看到屏幕滚动开始处理,大约半分钟之后视频就转换完毕了,转换后mp4视频大小是17M,具体可以下载下来看一下
