1. 下载http://code.google.com/p/rowboat/专用的android2.3 从这里下载和官方的区别是 增加了两个目录 /hardware/ti/omx /external/ti-dsp 2.DVSDK: Digital video software development kit 里面有dsplink,dsp/bios,codec-enginer,codec-omap3530专用编解码器，dvtb,demo,linux内核 3.dvsdk安装到android中 ti-dsp/目录下有 fake-toolchain get_tidsp.sh install_dvsdk4.exp Makefile md5sum.list patches 包含了安装脚本，方便对dvsdk的安装，包括环境配置，脚本文件先判断有没有安装的目录是否已经安装好 再看有没有安装包，最后就是打补丁 运行脚本的时候需要装expect tcl8.5.12-src.tar.gz tk8.5.12-src.tar.gz expect5.45.tar.gz ./configure make make install 默认安装的路径是/usr/local/ 所以需要改ti-dsp里的脚本 install_dvsdk4.exp #!/usr/local/bin/expect -f 编译android的时候进行安装 android/build/core/rowboat.mk DSP_PATH := $(wildcard external/ti-dsp) 编译omx和ti-dsp,omx要使用ti-dsp的dvsdk中的库所又先编译 make -C external/ti-dsp combo_target=$(combo_target) $(combo_target)TOOLS_PREFIX=$($(combo_target)TOOLS_PREFIX) HOST_PREBUILT_TAG=$(HOST_PREBUILT_TAG) make -C hardware/ti/omx combo_target=$(combo_target) $(combo_target)TOOLS_PREFIX=$($(combo_target)TOOLS_PREFIX) HOST_PREBUILT_TAG=$(HOST_PREBUILT_TAG) 4.编译完后会自动把生成的库复制到文件系统中 cp /hardware/ti/omx/video/libomx_dsp_video_sharedlibrary.so out/target/product/myboard/system/lib cp /hardware/ti/omx/audio/libomx_dsp_audio_sharedlibrary.so out/target/product/myboard/system/lib cp /hardware/ti/omx/interface/libdspengineiface.so out/target/product/myboard/system/lib 5.生成ko out/target/product/myboard/system/ti-dsp/ cmemk.ko cs.x64P dsplinkk.ko lpm_omap3530.ko sdmak.ko 修改init.rc # load DSP modules insmod /system/ti-dsp/cmemk.ko "phys_start=0x84f00000 phys_end=0x85900000 allowOverlap=1 useHeaplfPooIUnavailable=1" insmod /system/ti-dsp/dsplinkk.ko insmod /system/ti-dsp/lpm_omap3530.ko insmod /system/ti-dsp/sdmak.ko转载地址：http://oxkni.baihongyu.com/
