[Cin] Blu-ray encoding again

Fri Oct 16 03:24:02 CEST 2020

Andrew,
GG has been working on an integration of some of the ffmpeg Blu-ray patches
because it looks like they have stabilized.  He checked in final patches to
GIT which incorporated what worked so things are cleaner and more similar
now.  We tested on 2 different bluray viewing devices and encountered no
problems.  This was worked on for about 3 days but should be done now for
awhile anyway.  I know this is a low use Cinelerra feature BUT we use it
ourselves so it is important to us.

With Marton's patches from git clone -b mpegts
> https://github.com/cus/ffmpeg/
> and CinGG compiled with ffmpg.git I _nearly_ got some rendering.
>
> But option files still needed some modification
>
> For example I was running into x264 errors.
