Andrew, thanks for testing. I have downloaded all of your patches in case GG ever gets the time and energy to absorb some of them.

I think you mean ffmpeg from 4.2 to 4.3?

Thanks for correcting the above; it was getting late at night for me.

I rebuild CinelerraGG git
...
once again my X11R7 prefix bites me ....

It is always something!

error: /usr/share/cin/lv2/lsp-plugins.lv2/spectrum_analyzer_x1.ttl:278:2: missing ';' or '.'
error: /usr/share/cin/lv2/lsp-plugins.lv2/spectrum_analyzer_x1.ttl:278:2: expected `]', not `l'
lilv_world_load_file(): error: Error loading file `file:///usr/share/cin/lv2/lsp-plugins.lv2/spectrum_analyzer_x1.ttl'
lv2: lilv_plugin_instantiate failed

I wonder if we should add "spectrum_analyzer_x1" to l v2_blacklist.txt , but I am not sure of the correct format.?

I have seamonkey and Cin running at the same time, so CPU usage is high!

Interesting -- I had to look up seamonkey to "sea" what it was!
