Fixes were checked into GIT today include the following:

An ffmpeg segv was occurring with PAL100/75 bars when not RGB 8-bit; fix that was added is a patch to ffmpeg to not crash.  YUV (Settings->Format) is still not usable for this and perhaps some other ffmpeg filters.  Ugin found this and provided a good dump.

Shuttle driver (not USB_DIRECT) for the new Linux kernel 5.x was broken, but now fixed.  Most distros will not have upgraded to 5.0 of the kernel until that distro releases a new version.  So only because GG upgraded his Fedora development system to that kernel, that is why he discovered this.

When using ffmpeg to render, a select file name to render to was not working if there was not at least one period or one slash.  That is if you use a file name of just "demo" it crashed.  You would have had to use a file name of "demo." or "/tmp/demo".  Amazingly, it has been like this for years and was not noticed.  Ugin discovered this.

A fix was added so that the camera and projector in the Compositor are less jittery + MantisBT issue #185.

Fix was added for MantisBT timeline bug and missing audio waveform - MantisBT issue #189 & 190.
