This document records the FFmpeg-based video decoder on another Android platform. Unlike the decoder documented in the previous article, the decoder documented in this article no longer uses class libraries such as libavcodec.so, libavformat.so, and only uses a class library--libffmpeg.so. The source code for the video decoder C language comes from the simplest ffmpeg+sdl-based video player. The related con

Start as follows:FFmpeg is an open-source project developed based on Linux. The source code is incompatible with the C/C ++ compiler provided by the most common Visual Studio in windows. Therefore, it cannot be compiled using msvc ++. To use FFMPEG, the first problem to be solved is to configure a Linux-like compiling environment in windows, compile FFMPEG into a binary library, and then use it for further

The mencoder command line looks a little scary, so FFmpeg is used. In fact, most of the so-called conversion software is based on FFMPEG, and mencoder also uses FFMPEG. FFmpeg is used for mplayer organizations. So why can't many software convert some files and CODEC? This is because
