移植VLC到arm开发板

[sinat_35308350]

这两天在移植VLC到arm的板子，用的交叉编译，加了libmad库，配置如下：

./configure CC=arm-xilinx-linux-gnueabi-gcc CXX=arm-xilinx-linux-gnueabi-g++ ARCH=arm LDFLAGS=-L/home/xcw/workspace/vlc/vlc-2.2.4/src/.libs --host=arm-xilinx-linux-gnueabi --enable-run-as-root --prefix=/home/xcw/workspace/vlc/vlc2 --enable-debug --disable-avcodec --disable-hal --disable-avformat --disable-swscale --disable-postproc --disable-a52 --disable-sdl --disable-fribidi --disable-dbus --disable-libgcrypt --disable-gnutls --disable-remoteosd --disable-x264 --disable-skins2 --disable-qt4 --disable-notify --disable-libxml2 --disable-freetype --disable-bonjour --disable-lua --disable-xcb --disable-glx --disable-opengl --disable-alsa --disable-vorbis --disable-ogg --disable-sqlite --enable-mad --with-mad=/home/libmad

然后make&make install，编译完成拷贝相关的bin文件和lib到开发板上，执行vlc以及cvlc出现如下错误：

/home/xcw # vlc AlwaysWithMe.mp3

运行aplay -l：

/home/xcw # aplay -L
null
    Discard all samples (playback) or generate zero samples (capture)

    audiocodec,

default:CARD=sndhdmi
    sndhdmi,

板子上的声卡是可以用的？请问是什么原因造成vlc播放不了mp3呢？

谢谢！！
