• ffplay is a simple media player based on SDL and the FFmpeg libraries.
• ffprobe is a is a simple multimedia stream analyzer.

and developers libraries:

• libavutil is a library containing functions for simplifying programming, including random number generators, data structures, mathematics routines, core multimedia utilities, and much more.
• libavcodec is a library containing decoders and encoders for audio/video codecs.
• libavformat is a library containing demuxers and muxers for multimedia container formats.
• libavdevice is a library containing input and output devices for grabbing from and rendering to many common multimedia input/output software frameworks, including Video4Linux, Video4Linux2, VfW, and ALSA.
• libavfilter is a library containing media filters.
• libswscale is a library performing highly optimized image scaling and color space/pixel format conversion operations.
• libswresample is a library performing highly optimized audio resampling, rematrixing and sample format conversion operations.

how to ffmpeg install for ubuntu 14

사실 인터넷에 많은 자료 들이 있지만, 자신의 환경과 일치하는 버전와 tip 을 사용해야 한다

본 문서 작성 당시, ubuntu14.04.1, ffmpeg-2.61, sdl2-2.0.3  을 사용하는데, ffmpeg, sdl2 은 수 많은 외부 라이브러리들이 사용되므로, 구조적으로 함수들이 재정의 되거나, 없어지거나, 새로 만들어지는 경우가 허다 하다

인터넷 자료들은 믿을만한 내용을 찾기가 쉽지 않다

배포사 사이트에서 guide 를 찾는 것이 가장 현명 하다

https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu

위의 url 을 참조하는 것이 좋으며, ffmpeg 빌드만 아래 내용을 참조한다. 아직 sdl2 와 호환 되지 않는 부분이 있어, makefile 만들기가 만만치 않다

cd ~/ffmpeg_sources
wget http://ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2
tar xjvf ffmpeg-snapshot.tar.bz2
cd ffmpeg

이것 저것 넣었다가 빼보고 테스트 하느라, 누락 된 부분이 있을 수 있어, 추후 ubuntu 초기화 하고 다시 정리해야 한다 ( remind )
