github上面找到两本红宝书, 不敢独享:
参考链接1: allwinner-zh/media-codec
-----------------------------------
有找到几个相关的文档:
参考链接2: CamDroid编译第三方app
参考链接3: camdroid使用的linux ndk版本 android-ndk-r8b-linux-x86.tar.bz2
参考链接4: camdroid使用的windows ndk版本 android-ndk-r8b-windows.zip
参考链接5: Android NDK 工具链的使用方法（Standalone Toolchain）
参考链接6: 直接使用ndk提供的arm-linux-androideabi-gcc编译android可执行程序
使用 make-standalone-toolchain.sh --platform=android-14 可以创建单独的工具链,
# /d/Downloads/android-ndk-r8b/build/tools/make-standalone-toolchain.sh --platform=android-14
Auto-config: --toolchain=arm-linux-androideabi-4.6
Copying prebuilt binaries...
Copying sysroot headers and libraries...
Copying libstdc++ headers and libraries...
Creating package file: /tmp/ndk-/arm-linux-androideabi-4.6.tar.bz2
Cleaning up...
Done.
解压arm-linux-androideabi-4.6.tar.bz2, 设置系统PATH,
然后可以使用
arm-linux-androideabi-gcc.exe -o test test.c
这种方式创建camdroid可执行文件。

视频编码库 APIs:
VideoEncCreate 创建一个视频编码器
VideoEncDestroy 销毁视频编码器
VideoEncInit 初始化视频编码器
VideoEncUnInit 去初始化视频编码器
AllocInputBuffer 通过 vencoder 申请输入图像帧 buffer
GetOneAllocInputBuffer 获取一块由 vencoder 分配的图像帧
FlushCacheAllocInputBuffer 刷 cache 保持数据的一致性
ReturnOneAllocInputBuffer 还回由 vencoder 申请的图像帧
ReleaseAllocInputBuffer 释放由 vencoder 申请的图像帧
AddOneInputBuffer 添加一块输入的图像帧到编码器
VideoEncodeOneFrame 编码一帧图像
AlreadyUsedInputBuffer 获取编码器已经使用过的图像帧
ValidBitstreamFrameNum 获取有效的输出码流 buffer 的个数
GetOneBitstreamFrame 获取一个码流 buffer
FreeOneBitStreamFrame 还回码流 buffer
VideoEncGetParameter 获取编码器参数
VideoEncSetParameter 设置编码器参数
上面这些函数都可以在这个动态链接库 camdroid/frameworks/av/media/CedarX-Projects/CedarAndroidLib/LIB_JB42_F81/libvencoder.so 找到!

晕哥，那个camdroid的入口函数在哪里？？我找不到这个函数，然后我在烧写到板子的时候，找不到项目文件开始的入口位置，麻烦你知道一下

注册个账号支持一下晕哥，问一下我编译camdroid的时候出现
arm-linux-gnueabi-gcc: error trying to exec 'cc1': execvp: No such file or directory
用的编译器版本不对吗？搭建这环境需要哪个版本的编译器？
可能你的 PATH 设置不对 https://blog.csdn.net/hello404/article/details/17099903
也可能是 32/64bit Linux 兼容性问题。
