一、linux相关说明:
|
||
|
||
1. 每套linux so对应的编译工具链如下：
|
||
|
||
# arm926-uclibc for BU1 C500
|
||
# arm-openwrt-linux-muslgnueabi for BU2 Tina2.0
|
||
# arm-openwrt-linux-muslgnueabi-v for v5
|
||
# arm-openwrt-linux-uclibc for BU2 R16
|
||
so_dir: arm926-uclibc host: arm-linux toolchain_dir: uclibc_arm926_static
|
||
so_dir: arm-linux-gnueabi host: arm-linux-gnueabi toolchain_dir: external-toolchain
|
||
so_dir: arm-linux-gnueabihf host: arm-linux-gnueabihf toolchain_dir: 系统自带
|
||
so_dir: arm-none-linux-gnueabi host: arm-none-linux-gnueabi toolchain_dir: 系统自带
|
||
so_dir: arm-openwrt-linux-muslgnueabi host: arm-openwrt-linux toolchain_dir: OpenWrt-Toolchain-sunxi_gcc-5.2.0_musl-1.1.12_eabi.Linux-x86_64
|
||
so_dir: arm-openwrt-linux-uclibc host: arm-openwrt-linux toolchain_dir: toolchain_arm_uClibc
|
||
so_dir: arm-linux-gnueabihf-linaro host: arm-linux-gnueabihf toolchain_dir: gcc-linaro-arm-linux-gnueabihf-4.8-2014.01_linux
|
||
so_dir: arm-aarch64-openwrt-linux host: aarch64-openwrt-linux toolchain_dir: toolchain-sunxi-tina2.0-64
|
||
so_dir: arm-openwrt-linux-muslgnueabi-v5 host: arm-openwrt-linux-muslgnueabi toolchain_dir: linux-x86
|
||
|
||
2.编译步骤如下（以arm926-uclibc为例）：
|
||
|
||
2.1 export编译工具链：
|
||
TOOLS_CHAIN=/home/user/workspace/tools_chain/
|
||
export PATH=${TOOLS_CHAIN}/uclibc_arm926_static/bin:$PATH
|
||
|
||
2.2. 运行automake的相关工具：./bootstrap
|
||
|
||
2.3. 配置makefile：
|
||
2.3.1 模式：./configure --prefix=INSTALL_PATH --host=HOST_NAME LDFLAGS="-LSO_PATH"
|
||
2.3.2 示例：./configure --prefix=/home/user/workspace/libcedarc/install --host=arm-linux LDFLAGS="-L/home/user/workspace/libcedarc/lib/arm926-uclibc"
|
||
2.3.3 特别说明：如果内核用的是linux3.10, 则必须加上flag：CFLAGS="-DCONF_KERNEL_VERSION_3_10" CPPFLAGS="-DCONF_KERNEL_VERSION_3_10"
|
||
即：./configure --prefix=/home/user/workspace/libcedarc/install --host=arm-linux CFLAGS="-DCONF_KERNEL_VERSION_3_10" CPPFLAGS="-DCONF_KERNEL_VERSION_3_10" LDFLAGS="-L/home/user/workspace/libcedarc/lib/arm926-uclibc"
|
||
|
||
2.4 编译：make ; make install
|
||
|
||
二、版本改动说明：
|
||
|
||
1). CedarC-v1.0.4
|
||
|
||
1. 特别说明：
|
||
|
||
1.1 camera模块相关：( >=android7.0的平台需要进行如下修改,其他平台保持之前的做法)
|
||
修改的原因：a.omx和android framework都没有对NV21和NV12这两种图像格式进行细分，都是用OMX_COLOR_FormatYUV420SemiPlanar
|
||
进行表示，OMX_COLOR_FormatYUV420SemiPlanar即可以表示NV21，也可以表示NV12；
|
||
b.而ACodec将OMX_COLOR_FormatYUV420SemiPlanar用作NV12，camera将OMX_COLOR_FormatYUV420SemiPlanar用于NV21，
|
||
之前的做法是omx_venc通过进程的包名进行区分兼容，若调用者是ACodec，则用作NV12，若调用者是camera，则用作
|
||
NV21；
|
||
c.android7.0因为权限管理的原因，无法获取到进程的包名，所以无法在omx_venc进行兼容，只能在上层caller层进行
|
||
兼容，而cts会对ACodec的接口进行测试，若改动ACodec，则会响应到cts测试，所以只能修改camera
|
||
d.修改的原则为：扩展图像格式的枚举类型的成员变量OMX_COLOR_FormatYVU420SemiPlanar，用于表示NV21；
|
||
即 OMX_COLOR_FormatYUV420SemiPlanar --> NV12
|
||
OMX_COLOR_FormatYVU420SemiPlanar --> NV21
|
||
|
||
修改的地方：
|
||
a. 同步头文件：同步openmax/omxcore/inc/OMX_IVCommon.h 到./native/include/media/openmax/OMX_IVCommon.h
|
||
b. camera模块在调用openmax/venc编码接口时需要进行修改：
|
||
修改前 NV21 --> OMX_COLOR_FormatYUV420SemiPlanar，
|
||
修改后 NV21 --> OMX_COLOR_FormatYVU420SemiPlanar;
|
||
|
||
1.2 加载解码库的说明：
|
||
之前加载解码库的操作在vdecoder.c这一层进行，为了提高灵活性，从v1.0.4后
|
||
把加载解码库的操作放到上层调用者进行，上层可调用vdecoder.c的AddVDPlugin接口默认
|
||
加载所有的子解码，或者参照如下代码按需加载：
|
||
|
||
static void InitVDLib(const char *lib)
|
||
{
|
||
void *libFd = NULL;
|
||
if(lib == NULL)
|
||
{
|
||
loge(" open lib == NULL ");
|
||
return;
|
||
}
|
||
|
||
libFd = dlopen(lib, RTLD_NOW);
|
||
|
||
VDPluginFun *PluginInit = NULL;
|
||
|
||
if (libFd == NULL)
|
||
{
|
||
loge("dlopen '%s' fail: %s", lib, dlerror());
|
||
return ;
|
||
}
|
||
|
||
PluginInit = (VDPluginFun*)dlsym(libFd, "CedarPluginVDInit");
|
||
if (PluginInit == NULL)
|
||
{
|
||
logw("Invalid plugin, CedarPluginVDInit not found.");
|
||
return;
|
||
}
|
||
logd("vdecoder open lib: %s", lib);
|
||
PluginInit(); /* init plugin */
|
||
return ;
|
||
}
|
||
|
||
static void AddVDLib(void)
|
||
{
|
||
InitVDLib("/system/lib/libawh265.so");
|
||
InitVDLib("/system/lib/libawh265soft.so");
|
||
InitVDLib("/system/lib/libawh264.so");
|
||
InitVDLib("/system/lib/libawmjpeg.so");
|
||
InitVDLib("/system/lib/libawmjpegplus.so");
|
||
InitVDLib("/system/lib/libawmpeg2.so");
|
||
InitVDLib("/system/lib/libawmpeg4base.so");
|
||
InitVDLib("/system/lib/libawmpeg4normal.so");
|
||
InitVDLib("/system/lib/libawmpeg4vp6.so");
|
||
InitVDLib("/system/lib/libawmpeg4dx.so");
|
||
InitVDLib("/system/lib/libawmpeg4h263.so");

说明：修改原因为：根据BU1最新提供的工具链进行整理；
|
||
前面3套为用得比较多的编译工具链，适用于各个BU的方案开发；
|
||
后面6套为BU1提供的工具链编译出来的so，如果其他BU需要使用，建议先与cedarc驱动组的同事（如王喜望/刘小燕）进行沟通了解；
