 Summary of the bug:

 HTTP streams featuring Ogg Vorbis content appear to leak memory with the
 resident size increasing in pace with the input data. Eventually constant
 mmap and munmap calls in the main ffmpeg thread cause an increase in CPU
 usage well beyond reason.

 This '''does not''' occur with ffmpeg 4.2.3, nor does it seem to occur
 with other codecs (MP3 and AAC at least).

 How to reproduce:
 ffmpeg -i http://sharprouter.sharp-stream.com:8000/totallyradio.ogg -f
 null -
 ffmpeg version 4.3 Copyright (c) 2000-2020 the FFmpeg developers
   built with gcc 9.3.0 (Gentoo 9.3.0-r1 p3)
 Patches should be submitted to the ffmpeg-devel mailing list and not this
 bug tracker.
