Design of the audio and video format conversion based on FFMPEG
Ming Diao · Applied science and technology · 2013
The demand for audio and video conversion,which can be achieved by using the free,open source software FFMPEG,widely exists in our life.However,it lacks of the encoders H264 and MP3 which are commonly used.It can be compensated by using external function library.In order to solve the problem,first,compile of FFMPEG is necessary;besides,by adding libx264 and libmp3lame during the installation and compile,a video which is encoded by H264 video encoder and MP3 audio encoder is obtained.Finally,writing and debugging C program by calling the interface functions of FFMPEG can achieve the design and the experiment proves that FFMPEG can realize video format conversion very well,the video encoding mode and audio encoding mode can be changed according to demand,and the project has very strong portability.
