Andrea,

PS: Now that I'm back in front of the PC, I'd like to start testing
patches again. Phyllis, which one are you testing?

Well, I finally fully charged up the android tablet and installed Termux and I see a familiar terminal window -- I can barely use the tablet but did find out that it has Android 8.x installed on it.

Meanwhile, I am going to try to work through more of Randrik15 starting at 0001- and so on.  I have gone over only a few ones further on.
Also, there is a new plugin that has been checked into GIT.
And the Freelancer, who has had some FFmpeg experience sees the problem with the Bluray Patch #2 for version 4.4 -- BUT it is not just bluray as there is dropped ending frames in some videos when using h265-10bit render format that is fully reproducible.

P.S. I have to rack my brain for Wayland and see if I can test that somehow.
