Comment (by Arno Le Prioux):

 Replying to [comment:3 richardpl]:
 > I think that VST host without GUI stuff (thus with limited
 functionality) could be done in similar way as LADSPA and LV2 host are
 done in libavfilter.
 > Main reason why I never wrote VST host code in libavfilter is because of
 nightmare to get SDK build and running with VST plugins.
 > There are open source VST plugins if you did not know.

 Yes ! The VST SDK has a command line VST host for testing compliance to
 their API model. It's called something like VST tester or something. You
 can compile it and see the source code. You could discard the test
 classes/methods and keep the host and add it to ffmpeg. And yes you could
 implement it like ladspa on how to call your VST plugins in ffmpeg's and
 edit the parameters !
 The big advantage would be that ffmpeg could tap into the numerous free
 VST Plugins that are out there.
 That's what I was hoping to get by going by starting this ticket 😅
