Regarding appimage, in a comment on one of my videos I was asked:
"1- when I enable lv2 plugins, cinelerra never loads up on me.
LV2 plugins have a file called lv2_blacklist.txt in the main Cinelerra directory for just such problems. There are a lot of lv2 plugins that are compiled for older or specific Operating Systems and they simply will not work with Cinelerra because of bad input/output. When you start CinGG from a terminal (using the non-AppImage way), it puts out a message specifying the LV2 that it can not handle. Then we can add this to the blacklist so it is no longer a problem. The user can add it manually (but unfortunately not with AppImage) or remove the non-working LV2 plugin from their directory.
But in this case, the user should limit their LV2 plugins to ones that work. Calf LV2 plugins always seem to work. A description of how to set the path to limit the plugins is a few paragraphs down in:
2- is background rendering and render farm in CLI mode works now, when
Cinelerra-GG is distributed as AppImage?"
I have to test this yet and get back to you.
