libavfilter-extra7 - 7:4.1.10-0+deb10u1 main

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:
.
* Lens correction using Lensfun
* Optical Character Recognition (uses Tesseract)
* SOFAlizer (Spatially Oriented Format for Acoustics, uses netcdf)
.
