Package goav contains the codecs (decoders and encoders) provided by the libavcodec library Provides some generic global options, which can be set on all the encoders and decoders. Package goav deals with the input and output devices provided by the libavdevice library The libavdevice library provides the same interface as libavformat. Namely, an input device is considered like a demuxer, and an output device like a muxer, and the interface and generic device options are the same provided by libavformat Package goav contains methods that deal with ffmpeg filters filters in the same linear chain are separated by commas, and distinct linear chains of filters are separated by semicolons. FFmpeg is enabled through the "C" libavfilter library Package goav provides some generic global options, which can be set on all the muxers and demuxers. In addition each muxer or demuxer may support so-called private options, which are specific for that component.
