[FFmpeg-user] showvolume filter memory leak

I'm testing the showolume filter to generate a single vumeter from an input
The filter works perfectly but eats memory. Approximately 500MBytes every 2

Using ffmpeg version 5.0-static on GNU/Linux 4.15.0-45-generic x86_64

In normal use I use an output nut format with a pipe to a vlc player. But
with a simple output to null it also has a memory leak.

My testing commandline:

ffmpeg -i udp://@ -filter_complex
-map [out] -map 0:a -an -c:v rawvideo -pix_fmt rgb24 -f null /dev/null
