Problems During MPlayer installation and Solutions

For more information about the problems and solutions during MPlayer installation-Linux general technology-Linux technology and application, see the following. Recently, when studying flv video technology, mplayer must be installed for rm/rmvb video conversion. Many problems have been encountered during the installation process and have been basically solved, so I will write it down for future reference and share it with you.

Download all the software packages as follows:
1)MPlayer-1.0rc1.tar.bz2 mplayer main program
2)all-20071007.tar.bz2 all encoding and decoding packages of mplayer
3366windows-all-20071007.zip same as above
4)gcc-3.4.0.tar.gz (optional)
5) libstdc ++-3.3.2-6. i386.rpm is also optional.

Before installation, make a note that all your software packages are stored in the/home/mbq directory. The gcc compiler required for MPlayer source code installation is the 2.9 series and the 3. X Series. If your machine's gcc version is not the same, the command for viewing the gcc version is as follows:

# Gcc-v
Use built-in specs.
Goals: i386-redhat-linux
Configuration :.. /configure -- prefix =/usr -- mandir =/usr/share/man -- infodir =/usr/share/info -- enable-shared -- enable-threads = posix -- enable-checking = release -- with-system-zlib -- enable-_ cxa_atexit -- disable-libunwind-exceptions -- enable-libgcj-multifile -- enable-versions ages = c, c ++, objc, obj-c ++, java, fortran, ada -- enable-java-awt = gtk -- disable-dssi -- enable-plugin -- with-java-home =/usr/lib/jvm/java-1.4.2-gcj-1.4.2.0/jre -- with-cpu = generic -- host = i386-redhat-linux
Thread model: posix
Gcc version 4.1.1 20070105 (Red Hat 4.1.1-52)

The installation takes about half an hour to fifty minutes. The command is executed as follows:

# Cd/home/mbq
# Tar xf gcc-3.4.0.tar.gz
# Cd gcc-3.4.0
#. /Configure -- prefix =/usr/local/The gcc-3.4.0 -- enable-threads = posix -- disable-checking -- enable -- long -- host = i386-redhat-linux -- with-system-zlib -- enable- ages = c, c ++, java
# Make
# Make install

After the installation is complete, connect the main program to the/usr/bin directory and back up the gcc program of the previous version first:

# Mv/usr/bin/gcc/usr/bin/gcc4
# Ln-s/usr/local/gcc-3.4.0/bin/gcc/usr/bin/gcc

Then, when viewing the gcc version, it should be shown as follows:

# Gcc-v
Reading specs from/usr/local/gcc-3.4.0/lib/gcc/i386-redhat-linux/3.4.0/specs
Configured :.. /gcc-3.4.0/configure -- prefix =/usr/local/gcc-3.4.0 -- enable-threads = posix -- disable-checking -- enable -- long-long -- host = i386-redhat-linux -- with-system-zlib -- enable-languages ages = c, c ++, java
Thread model: posix
Gcc version 3.4.0

After the compiler is installed, I found that libstdc ++ is required to convert the rm/rmvb format to the flv format. for so.5 support, first you have to check whether the inventory in/usr/lib is:

# Cd/usr/lib
# Ls-l | grep libstdc ++
Lrwxrwxrwx 1 root 18 11-21 libstdc ++. so.5-> libstdc ++. so.5.0.5
-Rwxr-xr-x 1 root 730768 libstdc ++. so.5.0.5

If you cannot find the two rows output above, install libstdc ++-3.3.2-6. i386.rpm and run the following command:

# Cd/home/mbq
# Rpm-ivh libstdc ++-3.3.2-6. i386.rpm

If the system prompts that a newer version has been installed, the prompt is as follows:

Preparing... ######################################## ### [100%]
Package libstdc ++-4.1.1-52. el5 (which is newer than libstdc ++-3.3.2-6) is already installed

Run the following command for installation:

# Rpm-ivh -- oldpackage libstdc ++-3.3.2-6. i386.rpm

After successful installation, we can start to install MPlayer.

# Cd/home/mbq
# Tar xf all-20071007.tar.bz2
# Mv all-20071007/*/usr/lib/codes
# Chmod 644/usr/lib/codes /*
# Chown root. root/usr/lib/codes /*
# Unzip windows-all-20071007.tar.bz2
# Mv windows-all-20071007/*/usr/lib/wincodes
# Chmod 644/usr/lib/wincodes /*
# Chown root. root/usr/lib/wincodes /*
# Tar xf MPlayer-1.0rc1.tar.bz2
# Cd MPlayer-1.0rc1
#. /Configure -- prefix =/usr/local/mplayer/-- enable-gui -- enable-freetype -- with-codecsdir =/usr/lib/codes/-- with-win32libdir =/usr/lib/ wincodes/
# Make
# Make install

In this way, we have successfully installed MPlayer. The installation directory is/usr/local/mplayer. Then we can use it for video conversion or other things.
