FFMPEG功能

1．  视频音频格式转换

Ffmpeg能使用任何支持的格式和协议作为输入：

*比如你可以输入YUV文件：ffmpeg -i /tmp/test%d.Y /tmp/out.mpg

它将要使用如下文件：

      /tmp/test0.Y, /tmp/test0.U, /tmp/test0.V,
/tmp/test1.Y, /tmp/test1.U, /tmp/test1.V,等等…

   *你能输入原始的YUV420P文件：ffmpeg -i /tmp/test.yuv /tmp/out.avi

   原始的YUV420P文件包含原始的YUV极性，每帧以Y平面开始，跟随U和V平面，它们是Y平面水平垂直的一半分辨率

   *你能输出原始的YUV420P文件

   ffmpeg -i mydivx.avi -o hugefile.yuv

This tutorial is about transcoding video fom one codec into another using
[url=http://ffmpeg.org/]FFMPEG[/url]
. I got deeper into FFMPEG when I wanted to transcode into FLV (Flash Video) and it works very well. I developed the
[url=http://rivavx.de/?encoder]Riva FLV Encoder[/url]
, a GUI for FFMPEG.

We install the Minimalist GNU for Windows MinGW (Compiler) and MSYS (Minimal SYStem) which is a kind of unix-shell to access the MinGW-commands. Next we download, compile and install Lame, an open-source mp3-codec, with MSYS. Next we install WinCVS and checkout the latest cvs-release of FFMPEG. Finally we compile ffmpeg and I will show a few examples how to work with Flash Video (FLV).
