Compile Mplayer in RHEL6

The Mplayer compilation process in RedHatEnterpriseLinux6 is very disturbing. Here is a special record: # wgethttp: // www1.mplayerhq. hu/MPlayer/releases/secrets #./configure # make error: libmp code

The Mplayer compilation process in Red Hat Enterprise Linux 6 is very disturbing. Let's take a note:

First

# Wget http://www1.mplayerhq.hu/MPlayer/releases/MPlayer-1.0rc4.tar.bz2
# Tar-zxvf MPlayer-1.0rc4.tar.bz2
#./Configure
# Make

Error:

Libmp codecs/vd_mpng.c: In function 'pngreadfn ':
Libmp codecs/vd_mpng.c: 77: error: dereferencing pointer to incomplete type
Libmp codecs/vd_mpng.c: In function 'decode ':
Libmp codecs/vd_mpng.c: 114: error: dereferencing pointer to incomplete type
Libmp codecs/vd_mpng.c: 131: error: dereferencing pointer to incomplete type
Make: *** [libmp codecs/vd_mpng.o] Error 1

After searching for half a day, I finally got confused on Google. Baidu is a bit unappealing:

Bug 354965-media-video-mplayer fails to compile against media-libs-libpng-1_5_x

It turned out to be a BUG. You can only use the latest version.

# Svn checkout svn: // svn. mplayerhq. hu/mplayer/trunk mplayer
#./Configure

There is an error message
No FFmpeg checkout, press enter to download one with git or CTRL + C to abort
Solution:
You may need to install git client and press enter during the above warning time

Press enter to automatically install git to obtain FFmpeg.

#./Configure no way. Use configure again

Error

Error: yasm not found, use -- yasm = ''if you really want to compile

Description: YASM is not found.

# Git clone git: // github.com/yasm/yasm.git
Or
# Wget http://www.tortall.net/projects/yasm/releases/yasm-1.1.0.tar.gz

Install yasm and re-enter mplayer

# Make-j 2

My machine is E5300 dual-core

# Make install

Successful

# Svn update
# Ldconfig
# Mplayer -- help

Finished!

Error
MPlayer was compiled without libmp 3lame support.

Lame Not Installed
# Wget http://sourceforge.net/projects/lame/files/lame/3.98.4/lame-3.98.4.tar.gz
# Tar-zxvf lame-3.98.4.tar.gz
# Cd lame-3.98.4
#./Configure -- enable-shared
# Make & make install

Re-compile the Mplayer.

Haha, compression rate 50%
