Obviously, it will hurt the performance of library quite a bit, so if performance is critical for you - you might want to fall back to earlier versions of NDK and FFmpeg. It seems that both GCC and Clang distributed inside most recent (r17b, at the moment of writing) NDK have troubles with ASM code of FFmpeg, which unfortunately forced me to turn it off. I haven’t noticed significant difference in case of FFmpeg, however if you would link FFmpeg with external library (like libx264 for instance), things might get ugly. It’s reported that sometimes Clang tends to produce larger and less-performant binaries (libs) than GCC does. GCC toolchain inside NDK has been deprecated for quite a while now and it’s highly advised to migrate to Clang (since GCC is not maintained). In this article, I will concentrate on the specifics of building FFmpeg with Clang. If you haven’t read it, please, take a look here: Building FFmpeg for Android, since I will skip some basic stuff that already was described here. Wherever the question of "best" cannot be answered they support both options so the end user can choose.This article is the continuation of my article about building FFmpeg for Android. The author slightly favors their own code to keep the dependencies on other libs low and to maximize code sharing between parts of FFmpeg. To achieve this they combine the best free software options available. The FFmpeg project tries to provide the best technically possible solution for developers of applications and end users alike. As well as ffmpeg, ffserver, ffplay and ffprobe which can be used by end users for transcoding, streaming and playing. It contains libavcodec, libavutil, libavformat, libavfilter, libavdevice, libswscale and libswresample which can be used by applications. No matter if they were designed by some standards committee, the community or a corporation. It supports the most obscure ancient formats up to the cutting edge. SmartFFmpeg adds a graphical user interface for those who would prefer it.įFmpeg is the leading multimedia framework, able to decode, encode, transcode, mux, demux, stream, filter and play pretty much anything that humans and machines have created. FFmpeg is a command line tool to convert multimedia files between formats.
