Your solution is a workaround that works for you and might for others so thank your very much for reporting this. Dav1d has been and will continue to be somewhat of a problem for Cinelerra because it has many requirements making it untenable for older Operating System distros. For example, below is a snippet from the manual: Problem - 0.6 dav1d requires NASM 2.14 and uses instructions like vgf2p8affineqb, not exactly an "add" instruction. It also uses meson which is not widely avail- able on all distros. The only distros that are built for CINELERRA-GG that are at 2.14 are the latest version of Arch, Debian(10), Gentoo, Tumbleweed, and Fedora(31). The rest are at 2.12 and 2.13 including the most widely used Ubuntu. The NASM requirement apparently provides for using AVX-512 in- structions (like vgf2p8affineqb, which is more like a whole routine than a simple instruction). Workaround already in use by CINELERRA-GG - a Makefile was generated to re- place Meson usage but has to be continuously updated for new releases. Dav1d 0.5 requires NASM 2.13 so at this level the newer distros mostly work. The availability of meson and nasm are a significant problem on many sys- tems which are still in wide use. However, we have switched from the monthly tars/packages builds (the last one was 10312020) to AppImage which should solve the library link problem you have noticed and future library updates. |
