![]() ![]() The command provides file details for title, encoder used, duration and brief summary of audio and video tracks including bitrate, codec, metadata etc. Basic Help Commands 1.1 File info – Get details of audio or video file Mentioned below are set of mostly widely used FFmpeg commands which can take care of most audio video processing requirements. For example, for an AVI file, unless user specifies, FFmpeg will use MPEG-4 for the video codec, and MPEG-2 for the audio codec. A file extension generally represents the container type.įFmpeg will generally attempt to automatically choose the video and audio codec based on the file extension. Container takes the responsibility of packaging, transportation and presentation. Codec define the way audio or video content is to be encoded or decoded.Ĭontainer : A container is the packager of files (read wrapper) in which video and audio is stored. H.264, HEVC, VC-1, VP8 are video codec while AAC, AC3, MP3, FLAC are audio codecs. ![]() Let us briefly understand and clear the confusion □Ĭodec : A codec is the name that the video or audio is stored in or simply put the protocol for compressing the audio and video data. A widely misunderstood and often interchangeably used term is codec and container. And finally the encoded packets are passed to the muxer to write them in defined container as the output file. The frames are then passed to the encoder which encodes them to desired form. The decoder generates uncompressed frames (raw video, PCM audio) which are processed further by filtering. Under the HOOD – A typical FFmpeg command execution involves passing the encoded packets to the decoder. FFmpeg is available across most platforms including Linux, Mac and Windows.Check here to compile and setup FFmpeg under windows and here for mac. ![]() FFmpeg uses a flow sequence on input file to demux, decode, encode and finally mux to generate requested outcome. It provides capability to record, transform and convert audio and video content in numerous forms and formats using easy to use commands. FFmpeg is an extremely powerful and flexible multimedia platform with extensive support to manage and process audio and video files. ![]()
