FFmpeg

FFmpeg is the best video framework because it can decode, encode, transcode, mux, demux, stream, filter, and play almost anything that people or computers have made. From the most obscure old files to the newest ones, it can handle them all. They are the same whether they were made by a standards group, the community, or a business. It's also very easy to carry: Testing infrastructure FATE can run, compile, and pass the program on Linux, macOS, Microsoft Windows, the BSDs, Solaris, and many other operating systems. It can do this with a lot of different build environments, machine architectures, and configurations. 

Apps can use the libavcodec, libavutil, libavformat, libavfilter, libavdevice, libswscale, and libswresample that are in it. ffmpeg, ffserver, ffplay, and ffprobe are also included so that end users can transcode, stream, and play. 

Tools for FFmpeg

ffmpeg: A command-line program that can change the format of video files 

ffserver: is a server for streaming multimedia for live shows. 

play ff: A simple video player built on top of SDL and FFmpeg 

ffprobe: is a simple file analysis for multimedia streams. 

FFmpeg Libraries for developers:

• libavutil is a library that has functions that make programming easier. It has random number generators, data structures, math methods, core multimedia utilities, and a lot more. 
• libavcodec is a package that has encoders and decoders for audio and video codecs. 
• libavformat is a package that has demultiplexers and multipliers for different types of multimedia files. 
• The libavdevice library has input and output devices that can grab from and render to a number of popular multimedia input/output software frameworks, such as ALSA, Video4Linux2, and Video4Linux. 
• The media filters in libavfilter are in a package. 
• libswscale is a library that does very fast and accurate picture scaling and conversions between color spaces and pixel formats. 
• libswresample is a tool that does resampling, rematrixing, and sample format conversion very efficiently.
