It is free to use software easily available online to download and install. Where multimedia files can be Audio, Video and Images too. Conclusion Of FFmpegįFmpeg is the core and powerful tool for encoding, decoding and transcoding the multimedia files. In this process encoded data packets are received and then multiplexed to provide output file. In this process encoding of data is done which comes from filter. While complex filtergraphs are that which have different output for input or one or more than one input and one or more than one output.
Simple filtergraphs provides the one output stream for one input stream.
So there are two types of Filter graphs known as Simple Filtergraph and Complex Filtergraph. Now this data passes from various chain of filters. This en-compress data goes for filtration process which is performed by libavfilter Library. Which decode the data and provide us decoded data frames. These encoded data packets works as a input for decoder. Which demultiplex the input file and provides the packets of encoded data. This library is used to make programming easy by performing various functions.Īs shown above in the figure working of FF-mpeg is divided into the 5 steps mentioned below, (1) Demultiplexer (2) Decoder (3) Filter (4) Encoder (5) Multiplexerįirst of all in this step Iibavcodec Library is called to read the input file. This library contains the multimedia filters. Where pixels of the images are considered for optimization. This library is used for scaling purpose.
This library is responsible for audio resampling and rematrixing. It contains Multiplexer and demultiplexer for different formats. It contains the encoder as well decoder for codec. This library contains the input and output devices, it used to grab and render to many software. There are 7 libraries in FFmpeg mentioned below, (1) LibavDevice (2) LibavCodec (3) LibavFormat (4) LibavSample (5) LibavScale (6) LibavFilter (7) LibavUtil
