移植Mplayer

Mplayer在Linux上安裝起來很方便，簡單的 configure，make一下，就裝好了，和QT的GUI配合，界面還是蠻友好的。Mplayer對媒體格式的廣泛支持，以及豐富的後期處理濾鏡，最新的版本更支持DIVX,H.264，MPEG4等最新的流媒體格式，可以實時在線播放視頻流，MPlayer大部分解碼庫都自帶了,如ffmpeg,但是自帶的音頻庫效果不好.換成使用libmad效果不錯.因此MPlayer在ARM-Linux的最簡單的移植只需要移植這兩個即可.移植後即進行字符界面的播放。

如果需要字幕支持.需要移植freetype庫.支持JPG皮膚需要 libjpeg庫,打開DVD光盤格式,需要dvdread,dvdnav等,支持pnm庫需要libpnm

MPlayer的面版主要採用X11支持.但移植X11需要大量工作，一般將其關掉。ARM版同樣可以加入live555支持,支持遠程的RTSP的流媒體播放器,方法同X86版類似。

一、開發環境

編譯系統：Linux12/kernel 2.6.32.24
開發板：Mini6410（nand 1024M,SDRAM 64M）
交叉編譯工具：arm-linux-gcc-4.5.1

實現mplayer，要從三方面著手：

1.編譯Kernel支持ALSA
2.編譯安裝libmad
3.User Mode支持./mplayer配置命令

二、移植Mplayer

1.移植準備
  a. 下載 libid3tag源代碼 (使用libid3tag -0.15.1b)
  b. 下載 libmad源代碼 (使用libmad-0.15.1b)
  c. 下載 Mplayer源代碼(使用Mplayer 1.0rc3)

2.編譯libid3tag
  a. 配置.configure
   #./configure --host=arm-linux --disable-shared --prefix=/usr/local/arm/4.5.1/lib CC="arm-linux-gcc"  \
      --disable-shared –enable-static \
      CPPFLAGS="-I/usr/local/arm/4.5.1/lib/include" \
      LDFLAGS="-L/usr/local/arm/4.5.1/lib/lib"
  b.編譯並安裝libid3tag
        #  make CC=arm-linux-gcc
        #  make CC=arm-linux-gcc install

這一步的目的是在/usr/local/arm/4.5.1/lib下生成lib目錄，在lib目錄下生成include和lib兩個檔夾，對應檔夾中生成id3tag.h和libid3tag.a檔，這兩個檔供mplayer編譯用。

3.編譯libmad
  a. 配置.configure
   #./configure --enable-fpm=arm --host=arm-linux --disable-shared --prefix=/usr/local/arm/4.5.1/lib CC="arm-linux-gcc"
   b. 編輯Makefile：將-fforce-men參數移除
       (原因是gcc 4.4 或者更高版本，已經將其去除了，所以會出現上面的錯誤！)
   c. 編譯並安裝libmad
   #  make CC=arm-linux-gcc
   #  make CC=arm-linux-gcc install

如果不先配置安裝libmad，則在make mplayer時出現找不到mad.h 錯誤，這一步的目的是在/usr/local/arm/4.5.1/lib下生成lib目錄，在lib目錄下生成include和lib兩個檔夾，對應檔夾中生成mad.h和libmad.a檔，這兩個檔供mplayer編譯用。?

4.編譯Mplayer

a. 配置.configure

# ./configure --host-cc=gcc --cc=arm-linux-gcc --target=arm --enable-static --disable-win32dll --disable-dvdread --disable-dvdread-internal --disable-dvdnav --disable-libdvdcss-internal --enable-fbdev --disable-mencoder --disable-live --disable-mp3lib --disable-mad --enable-libavcodec_a --language=zh_CN --disable-live 2>&1 | tee logfile

b. 編譯
#  make CC=arm-linux-gcc

測試
./mplayer *.mp3
./mplayer *.avi
./mplayer *.rmvb

支持一下

rc3不知道如何提供libmad编译出来的mad.h和libmad.a的路径......

这其中的第一句：1.編譯Kernel支持ALSA
如何实现呢？
我现在编译，make的时候，出现libasound.a中找不到clock_gettime
上网搜索发现和alsa有关系。
这个问题该如何解决呢？
谢谢。
板子是210

这其中的第一句：1.編譯Kernel支持ALSA
如何实现呢？

这里指的是内核镜像里需要包含ALSA架构的音频驱动。如果你用的是光盘上的内核源代码，里面应该已经包含了。

我现在编译，make的时候，出现libasound.a中找不到clock_gettime

能否把你的步骤和完整的编译信息传上来？

晚点我会回复这些代码的。
现在的问题是在fedora下面交叉编译的时候出现这些问题。

具体内容请看附件。
libmad已经make成功了，按照二楼的方法。

说明一下，因为参考了网络上的其他编译方法，所以我这里用的是mplayer 1.0rc2，用rc3，其实也是这个结果，因为测试过的。

此外，在libmpeg2的中的motion_comp_arm_s.S文件开头，加入了如下内容：
#ifndef HAVE_PLD
.macro pld reg
.endm
#endif
@ motion_comp_arm_s.S
实际上，加与不加，编译结果都是一样的。
make的log在附件中。

'config.h' and 'config.mak' contain your configuration options.
Note: If you alter theses files (for instance CFLAGS) MPlayer may no longer
      compile *** DO NOT REPORT BUGS if you tweak these files ***

'make' will now compile MPlayer and 'make install' will install it.
Note: On non-Linux systems you might need to use 'gmake' instead of 'make'.

NOTE: Win32 codec DLLs are not supported on your CPU (arm) or your
operating system (Linux). You may encounter a few files that cannot
be played due to missing open source video/audio codec support.

Check configure.log if you wonder why an autodetection failed (make sure
development headers/packages are installed).

NOTE: The --enable-* parameters unconditionally force options on, completely
skipping autodetection. This behavior is unlike what you may be used to from
autoconf-based configure scripts that can decide to override you. This greater
level of control comes at a price. You may have to provide the correct compiler
and linker flags yourself.
If you used one of these options (except --enable-gui and similar ones that
turn on internal features) and experience a compilation or linking failure,
make sure you have passed the necessary compiler/linker flags to configure.

If you suspect a bug, please read DOCS/HTML/en/bugreports.html.

从命令"readelf -s /opt/FriendlyARM/toolschain/4.5.1/arm-none-linux-gnueabi/lib/librt-2.11.so |grep clock_gettime"的输出来看，clock_gettime()应该是包含在librt-2.11.so里的：
