[Cin] megapile 12 (freebsd, ffmpeg 5, dynamic build, opencv trim)

[Andrea paz]

I added to megapile_12 the patch 0001-.....
I uncommented the line with "truehd" in bdcreate.C
I built CinGG without problems.
I started CinGG from root.
In BD Render the profile "truehd" appeared. The render progresses up
to 100% then there is a crash. At the terminal I have:

Render::render_single: Session finished.

Despite the CinGG crash, I get a bd.m2ts file. Ffprobe indicates:
