Because GG is preparing early for the end of the month builds, he has had to modify the blds directory scripts to accommodate the various Operating Systems and to get the best solution for the widest variations of usage. So if doing your own builds, you may have to do some minor adjustments or more library installs and re-run bld_prepare.sh. For example with the inclusion of AV1, WebP, and Shuttle USB Direct, some new libraries have to be installed. Also, he has changed Shuttle inclusion to "yes", thus requiring libusb-1.0-0 dev be installed unless you revert to Shuttle inclusion of "no". Some new libraries that *might *be needed: libwebp-1.0.2 - for WebP libtoolize - for WebP libaom-v1.0.0 - for AV1 libusb-1.0-0 dev - for Shuttle Pro to ensure K14/K15 function properly (and it is just better too). I hope this clarifies things. I should have relayed this information earlier. If any problems, let us know so we can fix them. gg/pys
