The FFMPEG software is only a decoding and encoding software. If multiple formats are supported, you must first install the corresponding library. Next let's talk about the library I installed.

The FFMPEG software is only a decoding and encoding software. If multiple formats are supported, you must first install the corresponding library. The following describes the library I installed:
1. Install faad2

# Wget http://downloads.sourceforge.net/faac/faad2-2.6.1.tar.gz
# Tar xvfz faad2-2.6.1.tar.gz
# Cd faad2
#./Bootstrap
#./Configure
# Make
# Make install

2. Install liba52

# Wget http://liba52.sourceforge.net/files/a52dec-0.7.4.tar.gz
# Tar xvfz a52dec-0.7.4.tar.gz
# Cd a52dec-0.7.4
#./Configure
# Make
# Make install

3. Install libdirac

# Wget http://downloads.sourceforge.net/dirac/dirac-0.10.0.tar.gz
# Tar xvfz dirac-0.10.0.tar.gz
# Cd dirac-0.10.0
#./Configure
# Make
# Make install

4. Install faac2

# Wget http://downloads.sourceforge.net/faac/faac-1.26.tar.gz
# Tar xvfz faac-1.26.tar.gz
# Cd faac
#./Bootstrap
#./Configure
# Make
# Make install

5. Install libamrnb

# Wget http://ftp.penguin.cz/pub/users/utx/amr/amrnb-7.0.0.2.tar.bz2
# Tar xvfj amrnb-7.0.0.2.tar.bz2
# Cd amrnb-7.0.0.2
#./Configure
# Make
# Make install

6. Install libamrwb

# Wget http://ftp.penguin.cz/pub/users/utx/amr/amrwb-7.0.0.3.tar.bz2
# Tar xvfj amrwb-7.0.0.3.tar.bz2
# Cd amrwb-7.0.0.3
#./Configure
# Make
# Make install

7. Install libmp 3lame

# Wget http://downloads.sourceforge.net/lame/lame-3.97.tar.gz
# Tar xzf lame-3.97.tar.gz
# Cd lame-3.97
#./Configure
# Make
# Make install

8. Install libx264
This package needs to be obtained using git, so install git first:

# Wget http://kernel.org/pub/software/scm/git/git-1.6.2.tar.gz (address to confirm)
# Tar zxvf git-1.6.2.tar.gz
# Cd git-1.6.2
#./Configure
# Make
# Make install

Then install libx264

#/Usr/local/bin/git clone git: // git.videolan.org/x264.git x264
# Cd x264
#./Configure -- enable-pthread -- enable-shared -- disable-ASM
# Make
# Make install

8. Install libnut. The software requires SVN to obtain the source code. SVN can be directly installed using Yum install SVN. Download first:

# SVN Co SVN: // SVN. mplayerhq. hu/nut/src/trunk libnut

After the download, the code is saved in the newly created libnut directory. For 64-bit Linux, You need to modify the configuration file:

# Cd libnut
# Vi config. Mak

Add the following in the next line of the last cflags:

Cflags + =-FPIC

Then compile and install:

# Make
# Make install

9. Install libogg

# Wget http://downloads.xiph.org/releases/ogg/libogg-1.1.3.tar.gz
# Tar xvf libogg-1.1.3.tar.gz
# Cd libogg-1.1.3
#./Configure
# Make
# Make install

10. Install libtheora (obtained by SVN)

# SVN Co http://svn.xiph.org/trunk/theora theora
# Cd theora
#./Autogen. Sh
#./Configure
# Make
# Make install

11. Install libvorbis

# Wget http://downloads.xiph.org/releases/vorbis/libvorbis-1.2.0.tar.gz
# Tar xvfz libvorbis-1.2.0.tar.gz
# Cd libvorbis-1.2.0
#./Configure
# Make
# Make install

12. Install libxvid

# Wget http://downloads.xvid.org/downloads/xvidcore-1.2.1.tar.gz
# Tar xvf xvidcore-1.2.1.tar.gz
# Cd xvidcore-1.2.1/build/generic
#./Bootstrap. Sh
#./Configure -- disable-assembly
# Make
# Make install

After the above media support library is installed, you can set the environment to prepare for compiling FFMPEG!
13. Modify Environment Variables

# Vi/etc/lD. So. conf

Add a line at the end of the file:

/Usr/local/lib

Then take effect:

# Ldconfig

14. Install FFMPEG
It can be obtained through SVN, but the file is large, so it is particularly slow:

# SVN checkout SVN: // SVN. mplayerhq. hu/FFMPEG/trunk FFMPEG
# Cd FFMPEG

You can also download it by yourself:

# Http://www.ffmpeg.org/releases/ffmpeg-0.5.tar.bz2
# Bzip2-D ffmpeg-0.5.tar.bz2
# Tar-XF ffmpeg-0.5.tar
# Cd ffmpeg-0.5

Compile (the pkg_config_path parameter must be set for 64-bit systems ):

# Export pkg_config_path =/usr/local/lib/pkgconfig cflags = "-FPIC-M64"
#./Configure -- enable-shared \
-- Enable-GPL \
-- Enable-nonfree \
-- Enable-postproc \
-- Enable-avfilter \
-- Enable-avfilter-lavf \
-- Enable-pthreads \
-- Enable-libamr-Nb \
-- Enable-libamr-WB \
-- Enable-libdirac \
-- Enable-libfaac \
-- Enable-libfaad \
-- Enable-libfaadbin \
Enable-libmp3lame \
-- Enable-libnut \
-- Enable-libtheora \
-- Enable-libvorbis \
Enable-libx264 \
-- Enable-libxvid \
-- Enable-decoder = libx264 \
-- Enable-Encoder = libx264
# Make
# Make install

14. Possible errors:

/Usr/include/Linux/videodev. h: 56: Error: syntax error before "ulong"
/Usr/include/Linux/videodev. h: 72: Error: syntax error before '} 'token
Libavdevice/v4l. C: In function 'Grab _ read_header ':
Libavdevice/v4l. C: 75: Error: storage size of 'tuner' isn' t known
Libavdevice/v4l. C: 133: Error: Invalid application of 'SIZE' to incomplete type 'video _ tuner'
Libavdevice/v4l. C: 140: Error: Invalid application of 'SIZE' to incomplete type 'video _ tuner'
Libavdevice/v4l. C: 75: Warning: unused variable 'tuner'

This may be because the source code videodev. H is not written for the next version of Linux. The standard C does not have the ulong type, so it must be changed to unsigned long.

15. Run FFMPEG-formats. Possible errors:

FFmpeg: Error while loading shared libraries: libavfilter. so.0: cannot open shared object file: no such file or directory

The environment path is not set. Add an FFMPEG. conf configuration file:

# Cd/etc/lD. So. conf. d
# Vi FFMPEG. conf

Write in the file:

/Usr/local/lib

Then confirm the effectiveness:

# Ldconfig
