文章大概就是源码编译 ffmpeg，支持H265 264 编码和gdb 调试
- 下载ffmpeg 源码
git clone https://git.ffmpeg.org/ffmpeg.git ffmpeg - 下载依赖库
sudo apt-get install libx264-dev libx265-dev - 编译选项
./configure --enable-gpl --enable-libx264 --enable-libx265 --enable-shared --enable-debug --disable-stripping --extra-cflags="-g" --extra-ldflags="-g" --prefix=`pwd`/builddir
make -j8- 生成文件如下
builddir compat config_components.h configure COPYING.GPLv2 COPYING.LGPLv2.1 CREDITS ffbuild ffmpeg_g ffprobe_g INSTALL.md libavdevice libavformat libpostproc libswscale MAINTAINERS presets RELEASE tools
Changelog config.asm config.h CONTRIBUTING.md COPYING.GPLv3 COPYING.LGPLv3 doc ffmpeg ffprobe fftools libavcodec libavfilter libavutil libswresample LICENSE.md Makefile README.md test
make install- 在调试之前需要配置ffmpeg库的依赖路径
