No problem -- testing of all the distros is most easily done here when we
do the monthly builds. In fact we were quite surprised at the Slackware
build working so well here.

That is funny! a Cin OS!
Also, FYI - we did contact dav1d software guru - JBKempf - and gave him our
compliments and stated our concerns which he considered. Just wanted to
let him know that one of our biggest concerns was the impediment other
software packages may have incorporating libdav1d into their packages for
the same reasons. But in the end, like most developers, he prefers to move
forward with the latest.
We still think it is worth putting into Cinelerra and hope that ffmpeg
eventually adds an encode speed up too. Phyllis/GG
