"John"
My Cinelerra-GG Solus package is almost ready, but there is a blocker.
Video effects that use vaapi don't work and in terminal I get:
PluginFVClient::process_buffer() F_denoise_vaapi
  err: Operacja niedozwolona (that means "operation not allowed" in english).

Today's GIT checkin has the plugin.opts file updated to comment out F_denoise_vaapi, deinterlace, procamp, scale,  and sharpness.  Thank you for discovering this and letting us know. 

P.S. I forgot to ask about this "Second is just a suggestion. If you do make install -j# (# means number of cores) build will fail" but will do so soon.  gg/Phyllis
