libavfilter-extra6-dbgsym 7:3.2.2-2 (armhf binary) in ubuntu zesty

 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)
 .
