S3C2410下mplayer音視頻播放器移植--馮勇老師

1、S3C2410下mplayer音視頻播放器移植 作者：武漢華嵌嵌入式培訓(xùn)中心 講師 馮勇一、s3c2410移植ALSA及相關(guān)工具使用相關(guān)源碼文件ncurses-5.6.tar.gzalsa-lib-1.0.17.tar.bz2alsa-utils-1.0.17.tar.bz21. 設(shè)置環(huán)境變量export MEDIA_INSTALL_DIR=/home/linux/driver/mplay/media_install2. 編譯ncurses tar zxvf ncurses-5.6.tar.gzcd ncurses-5.6./configure -host=arm-linu

2、x -target=arm-linux -build=i686-linux -with-softfloat -prefix=/usr -without-ada CC=/opt/gcc-3.4.5-glibc-2.3.6/arm-softfloat-linux-gnu/bin/arm-softfloat-linux-gnu-gccmakemake install DESTDIR=$MEDIA_INSTALL_DIR2. 編譯alsa-lib tar jxvf alsa-lib-1.0.17.tar.bz2cd alsa-lib-1.0.17./configure -host=arm-l

3、inux -target=arm-linux -build=i686-linux -with-softfloat -prefix=/usr -disable-python CC=/opt/gcc-3.4.5-glibc-2.3.6/arm-softfloat-linux-gnu/bin/arm-softfloat-linux-gnu-gcc 修改Makefile,刪除掉aserver和alsalisp所有部分(各2處 );因為運行configure設(shè)置了-with-softfloat ，不然會出錯。makemake install DESTDIR=$MEDIA_INSTALL_DIR

4、3.編譯alsa-util tar jxvf alsa-utils-1.0.17.tar.bz2cd alsa-utils-1.0.17./configure -host=arm-linux -target=arm-linux -build=i686-linux -with-softfloat -prefix=/usr -with-alsa-prefix=$MEDIA_INSTALL_DIR/usr/lib -with-alsa-inc-prefix=$MEDIA_INSTALL_DIR/usr/include CC=/opt/gcc-3.4.5-glibc-2.3.6/arm-so

5、ftfloat-linux-gnu/bin/arm-softfloat-linux-gnu-gccmakemake install DESTDIR=$MEDIA_INSTALL_DIR4.相關(guān)工具使用(1)由于alsa util工具訪問音頻alsa設(shè)備目錄在/dev/snd下，可先創(chuàng)建一個腳本：create_snd_dev.shmkdir /dev/sndln -s /dev/controlC0 /dev/snd/controlC0ln -s /dev/pcmC0D0c /dev/snd/pcmC0D0cln -s /dev/pcmC0D0p /dev/snd/pcmC0D0pln -s /d

6、ev/mixer /dev/snd/mixerln -s /dev/timer /dev/snd/timer(2) 使用aplay直接播放wav文件 ./aplay xxx.wav二、s3c2410上mp3庫及madplay移植相關(guān)源碼文件zlib-1.2.3.tar.gzlibid3tag-0.15.1b.tar.gzlibmad-0.15.1b.tar.gzmadplay-0.15.2b.tar.gz1.編譯zlib-1.2.3 tar zxvf zlib-1.2.3.tar.gzcd zlib-1.2.3./configure -prefix=/home/linux/drive

7、r/mplay/media_install/usr修改MakefileCC=/opt/gcc-3.4.5-glibc-2.3.6/arm-softfloat-linux-gnu/bin/arm-softfloat-linux-gnu-gccAR=/opt/gcc-3.4.5-glibc-2.3.6/arm-softfloat-linux-gnu/bin/arm-softfloat-linux-gnu-ar rcRANLIB=/opt/gcc-3.4.5-glibc-2.3.6/arm-softfloat-linux-gnu/bin/arm-softfloat-linux-gnu-ranlibm

8、akemake install2. 編譯libid3tagtar zxvf libid3tag-0.15.1b.tar.gzcd libid3tag-0.15.1b./configure -prefix=/home/linux/driver/mplay/media_install/usr -host=arm-linux -disable-debugging CC=/opt/gcc-3.4.5-glibc-2.3.6/arm-softfloat-linux-gnu/bin/arm-softfloat-linux-gnu-gcc CPPFLAGS="-I/home/linux/drive

9、r/mplay/media_install/usr/include" LDFLAGS="-L/home/linux/driver/mplay/media_install/usr/lib"makemake install3. 編譯libmadtar zxvf libmad-0.15.1b.tar.gzcd libmad-0.15.1b./configure -prefix=/home/linux/driver/mplay/media_install/usr -host=arm-linux -disable-debugging CC=/opt/gcc-3.4.5-gl

10、ibc-2.3.6/arm-softfloat-linux-gnu/bin/arm-softfloat-linux-gnu-gcc CPPFLAGS="-I/home/linux/driver/mplay/media_install/usr/include" LDFLAGS="-L/home/linux/driver/mplay/media_install/usr/lib"make出現(xiàn)：cc1: error: unrecognized command line option "-fforce-mem"修改Makefile在Makefi

11、le中找到包含"fforce-mem"字符串，將其刪除即可；原因：gcc3.4或更高版本中，已將將該選項去除了。再重新make即可make install4. 編譯madplaytar zxvf madplay-0.15.2b.tar.gzcd madplay-0.15.2b./configure -prefix=/home/linux/driver/mplay/media_install/usr -host=arm-linux -disable-debugging -with-alsa CC=/opt/gcc-3.4.5-glibc-2.3.6/arm-softfloat

12、-linux-gnu/bin/arm-softfloat-linux-gnu-gcc CPPFLAGS="-I/home/linux/driver/mplay/media_install/usr/include" LDFLAGS="-L/home/linux/driver/mplay/media_install/usr/lib" make編譯出錯：/opt/gcc-3.4.5-glibc-2.3.6/arm-softfloat-linux-gnu/bin/arm-softfloat-linux-gnu-gcc -Wall -O2 -fomit-

13、frame-pointer -o madplay madplay.o getopt.o getopt1.o version.o resample.o filter.o tag.o crc.o rgain.o player.o audio.o audio_aiff.o audio_cdda.o audio_hex.o audio_null.o audio_raw.o audio_snd.o audio_wave.o audio_alsa.o  -L/media/LinuxWorks/p760/multimedia/myworks/media_install/usr/lib /usr/l

14、ib/libasound.so -ldl -lpthread -lrt /media/LinuxWorks/p760/multimedia/myworks/media_install/usr/lib/libmad.so /media/LinuxWorks/p760/multimedia/myworks/media_install/usr/lib/libid3tag.so -lz -lm -Wl,-rpath -Wl,/media/LinuxWorks/p760/multimedia/myworks/media_install/usr/lib -Wl,-rpath -Wl,/media/Linu

15、xWorks/p760/multimedia/myworks/media_install/usr/lib直接修改最后一步：/opt/gcc-3.4.5-glibc-2.3.6/arm-softfloat-linux-gnu/bin/arm-softfloat-linux-gnu-gcc -Wall -O2 -fomit-frame-pointer -o madplay madplay.o getopt.o getopt1.o version.o resample.o filter.o tag.o crc.o rgain.o player.o audio.o audio_aiff.o audio

17、install/usr/lib/libmad.so /media/LinuxWorks/p760/multimedia/myworks/media_install/usr/lib/libid3tag.so -lz -lm -Wl,-rpath -Wl,/media/LinuxWorks/p760/multimedia/myworks/media_install/usr/lib -Wl,-rpath -Wl,/media/LinuxWorks/p760/multimedia/myworks/media_install/usr/libmake install5.相關(guān)工具使用./madplay te

18、ars.mp3 三、MPlayer在s3c2410上移植(軟解碼)tar jxvf MPlayer-1.0rc2.tar.bz2cd MPlayer-1.0rc2./configure -cc=/opt/gcc-3.4.5-glibc-2.3.6/arm-softfloat-linux-gnu/bin/arm-softfloat-linux-gnu-gcc -host-cc=gcc -target=armv4l-linux -prefix=/home/linux/driver/mplay/media_install/usr -disable-w32threads -disable-dvdread -disable-mencoder -
