The past week and next week I will not have much time; I apologize.

I tried to compile CinGG and everything is OK.

I tried to compile with OpenCV taken from CinGG's git (--with-opencv=sta,tar=http://cinelerra-gg.org/download/opencv/opencv-20200306.tgz) and, although the build gives no errors, the plugins do not show up in CinGG. (I've no Python 2, only Python 3).

I tried a new build with the OpenCVs from their git (--with-opencv=sta,https://github.com/opencv/opencv.git) and this time the plugins are there and work in CinGG.

NOTE: trueHD does not appear in "BD render" to me unless I uncomment the line in bdcreate.C; why was it commented out?
