--------------------+--------------------
 Yestorday(2020 Sept 30th), during `port upgrade outdated`, when it comes
 to ffmpeg, it depends on graphviz.

 During the build of graphviz, mac complains about disk space full, so I
 freed more than 10GB disk space for it, after several seconds, it's full
 again,
 I have to stop the build, after clean the build, it freed 50GB disk space.
 I have to checkout to old version of macports-ports.git, and install an
 old graphviz, then install ffmpeg.

 This kind of behavior is really unpredictable, and hard for a normal user.

 Does macports-ports has a `stable' release branch that does not upgrade
 packages to such a new version?

 As to debian, it do have several release branches, like stable, testing,
 unstable, experimental.

 Description:          FFmpeg is a complete solution to record, convert and
 stream audio and video. It includes libavcodec, the leading
                       audio/video codec library. The project is made of
 several components: ffmpeg is a command line tool to convert
                       one video file format to another. It also supports
 grabbing and encoding in real time from a TV card. ffserver is
                       an HTTP (RTSP is being developed) multimedia
 streaming server for live broadcasts. Time shifting of live
                       broadcast is also supported. ffplay is a simple
 media player based on SDL and on the ffmpeg libraries. ffprobe
                       gathers information from multimedia streams and
 prints it in human- and machine-readable fashion. libavcodec is a
                       library containing all the ffmpeg audio/video
 encoders and decoders. Most codecs were developed from scratch to
                       ensure best performance and high code reusability.
 libavformat is a library containing parsers and generators for
                       all common audio/video formats.
