mipsel linux mplayer

Download MPlayer-1.0rc2

偶只想要decoder,所以拿掉encoder

./configure --enable-cross-compile --target=mips-linux --cc=mipsel-linux-uclibc-gcc --host-cc=gcc --disable-mencoder

make

然後錯誤出現囉

修改libavutil/internal.h
加入以下function


#if !HAVE_LLRINT
static av_always_inline long long llrint(double x)
{
return rint(x);
}
#endif /* HAVE_LLRINT */

#if !HAVE_LRINT
static av_always_inline long int lrint(double x)
{
return rint(x);
}
#endif /* HAVE_LRINT */

#if !HAVE_ROUND
static av_always_inline double round(double x)
{
return (x > 0) ? floor(x + 0.5) : ceil(x - 0.5);
}
#endif /* HAVE_ROUND */

#if !HAVE_ROUNDF
static av_always_inline float roundf(float x)
{
return (x > 0) ? floor(x + 0.5) : ceil(x - 0.5);
}
#endif /* HAVE_ROUNDF */

#if !HAVE_TRUNCF
static av_always_inline float truncf(float x)
{
return (x > 0) ? floor(x) : ceil(x);
}
#endif /* HAVE_TRUNCF */


降樣子就OK囉

mipsel-linux-uclibc-strip mplayer

將mplayer丟到target上執行

video out to framebuffer & no sound
./mplayer -vo fbdev -nosound 0001.AVI

允許丟棄frame
./mplayer -vo fbdev -nosound -framedrop ./鐵鉆山老二-43.29.mpeg

rescale to 320x240 frame rate 5, -ni是在處理不正確的avi format
./mplayer -vf scale=320:240 -fps 5 -zoom -vo fbdev -nosound -ni ./luna.avi

./mplayer -vo fbdev -nosound ./32.70_0002.wmv

連WMV都可以play,真是讚啊

Internet radio
./mplayer -playlist ../tunein-station-4.pls

如果使用libmad
執行時加上 -ac mad
