你好，请问一下 configure 配置最后面的参数
--extra-ldflags="$ADDI_LDFLAGS"
$ADDITIONAL_CONFIGURE_FLAG
这两个是在哪里定义的呢？

root@ubuntu:/home/wangzhong/ndkwork/ffmpeg-compile-shared-library-for-android-master/source/ffmpeg# ./build_android_arm.sh
/home/djia/android/android-ndk-r10/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin/arm-linux-androideabi-gcc is unable to create an executable file.
C compiler test failed.

If you think configure made a mistake, make sure you are using the latest
version from Git. If the latest version fails, report the problem to the
[email protected] mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solve the problem.

由于想ffmpeg支持h.264，请问是否在build 文件里加入相关参数，具体是？？？

SLIBNAME_WITH_MAJOR=${SLIBNAME_WITH_MAJOR}
SLIB_CREATE_DEF_CMD=${SLIB_CREATE_DEF_CMD}
SLIB_EXTRA_CMD=${SLIB_EXTRA_CMD}
SLIB_INSTALL_NAME=${SLIB_INSTALL_NAME}
SLIB_INSTALL_LINKS=${SLIB_INSTALL_LINKS}

@dxjia 能不能加下qq 多交流一下如何编译ffmpeg呢

我是在Ubuntu 16.04下编译，NDK为“android-ndk-r12b”，FFmpeg的版本为 3.1.3，按照您提供的“build_android_x86”脚本去编译，结果报错：/home/zhuo/android-ndk-r12b/toolchains/x86-4.9/prebuilt/linux-x86_64/bin/../lib/gcc/i686-linux-android/4.9.x/../../../../i686-linux-android/bin/ld: error: libavutil/../compat/strtod.o: incompatible target
请问该如何解决。

#include <libavcodec/avcodec.h> 存在这个方法
为什么还是报错
Error:(32) undefined reference to `av_register_all'?

我跟了下脚本发现configure 是通过pkg-config 寻找库的头文件和路径的，但在ndk下没有arm-linux-androideabi-pkg-config，所有会有这样的警告/arm-linux-androideabi-pkg-config not found, library detection may fail，所以--enable-libspeex失败了，无法支持speex

使用你github上的ffmpeg源码编译没有问题,说明我的环境应该是没有问题的,但是自己在官网下载的源码总是有各种各样的问题,除了configure还有其他文件需要处理么?

你编译的这个so库 应该是官方默认的？
我调用合字幕的指令 操作失败的，
应该是缺少libass 如果要新增额外的 如libass 库 应该如何操作呢？
