Introduction

FFMpeg
is a free video
library that can record and convert audio and video data. FFMpeg is
under GNU Lesser General Public License, but FFMpeg also uses some third
part library which maybe under GNU General Public License. So before
using FFMpeg library, you'd better spend some time on the license.

FFMpeg includes the following librarys

libavcodec: All of the video and audio encoders and decoders.

libavformat: Demuxers and muxers for audio and video formats.

libavutil: Useful utils of FFMpeg

Get FFMpeg Source Code

There are no formal release of FFMpeg, however, you can get FFMpeg source code on a daily basic.

Collapse

svn://svn.mplayerhq.hu/ffmpeg/trunk

For example, you can checkout source code using TortoiseSVN,

Compiling FFMpeg

FFmpeg is developed under Linux, but it can be compiled under most operating systems.

For Windows, FFMpeg can be compilied by MSYS and MingGW. If you
had setup MSYS and MingGW system correctly, you can compile FFMpeg under
it's folder.

1. Cleanup former build results.

Collapse

make distclean

2. Setup build parameters.

Collapse

./configure --enable-shared --disable-static --enable-memalign-hack

If there are no errors, and config.mak and config.h generated, you
can build the library, and then, if you want, you can install them into
MSYS environment.

Collapse

make
make install

Using FFMpeg in Your Visual C++ Environment

1. Create inttypes.h and stdint.h if you don't have them. Attachment
is a copy of these two files. You can get them from other place if you
want.

2. Setting up Additional Include Directories and Additional
Library Directories. By default, these folder is under your MSYS folder,
for example:

Collapse

/usr/local/include
/usr/local/lib

3. Add FFmpeg's shared libraries, include libavutil.lib libavcodec.lib libavformat.lib
:

4. Include the FFMpeg header,

Collapse

#include <ffmpeg/avformat.h>

#include <ffmpeg/avcodec.h>

Using the FFMpeg code

There are an example within FFMpeg, output_example.c. But if you
copied codes from this example, following tips may ensure you compiles
successfully.

1. Add required casts.

2. Change snprintf
to _snprintf
