Muhammad Faiz f8d429e0c5 avfilter/avf_showcqt: rewrite showcqt and add features 
add yuv444p, yuv422p, and yuv420p output format (lower cpu usage
on ffplay playback because it does not do format conversion)
custom size with size/s option (fullhd option is deprecated)
custom layout with bar_h, axis_h, and sono_h option
support rational frame rate (within fps/r/rate option)
relaxed frame rate restriction (support fractional sample step)
support all input sample rates
separate sonogram and bargraph volume (with volume/sono_v and
volume2/bar_v)
timeclamp option alias (timeclamp/tc)
fcount option
gamma option alias (gamma/sono_g and gamma2/bar_g)
support custom frequency range (basefreq and endfreq)
support drawing axis using external image file (axisfile option)
alias for disabling drawing to axis (text/axis)
possibility to optimize it using arch specific asm code

FFmpeg README

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Libraries

  • libavcodec provides implementation of a wider range of codecs.
  • libavformat implements streaming protocols, container formats and basic I/O access.
  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides a mean to alter decoded Audio and Video through chain of filters.
  • libavdevice provides an abstraction to access capture and playback devices.
  • libswresample implements audio mixing and resampling routines.
  • libswscale implements color conversion and scaling routines.

Tools

  • ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
  • ffplay is a minimalistic multimedia player.
  • ffprobe is a simple analysis tool to inspect multimedia content.
  • ffserver is a multimedia streaming server for live broadcasts.
  • Additional small tools such as aviocat, ismindex and qt-faststart.

Documentation

The offline documentation is available in the doc/ directory.
