Description:
FFmpeg library with extra media filters - runtime files
FFmpeg is the leading multimedia framework, able to decode, encode, transcode, mux, demux, stream, filter and play pretty much anything that humans and machines have created. It supports the most obscure ancient formats up to the cutting edge. . This library provides a generic audio/video filtering framework containing several filters, sources and sinks. . This package replaces the libavfilter6 package and contains the following additional filters: . * Optical Character Recognition (uses Tesseract) * SOFAlizer (Spatially Oriented Format for Acoustics, uses netcdf) . Because this package links against libraries that are licensed under Apache License 2.0, the resulting binaries are distributed under the GPL version 3 or later.
