@andrew I didn't quite understand your truehd audio example. I took 2 pcm s16 files I loaded them in CinGG and burned them as truehd: I have no errors and the rendering I loaded it again in CinGG with no errors. I don't think this is what you wanted. Following Phyllis' instructions (BD render) I render up to 100% and then I have these errors (from root): Render::render_single: Session finished. ** rendered 917 frames in 14.584 secs, 62.877 fps ++ dirname /tmp/bd_20220502-182538/bd.sh + sdir=/tmp/bd_20220502-182538 ++ cd /tmp/bd_20220502-182538 ++ pwd + dir=/tmp/bd_20220502-182538 + PATH=/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/lib/jvm/default/bin:/opt/rocm-5.1.1/bin:/opt/rocm-5.1.1/hip/bin:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl:/home/paz/cinelerra5/cinelerra-5.1/bin + mkdir -p /tmp/bd_20220502-182538/udfs ++ du -cb /tmp/bd_20220502-182538/bd.m2ts ++ tail -1 ++ sed -e 's/[ ].*//' + sz=45932544 + blks=26524 + rm -f /tmp/bd_20220502-182538/bd.udfs + '[' -f /tmp/bd_20220502-182538/bd.meta ']' + mkudffs -b 2048 /tmp/bd_20220502-182538/bd.udfs 26524 /tmp/bd_20220502-182538/bd.sh: line 14: mkudffs: command not found OpenCV: I compiled with opencv from the CinGG website. The build did not stop, but the result is that CinGG does not have the opencv plugins. See attachment. I can't give any errors when I try to start CinGG with ffmpeg5 and the opencv binaries. The terminal reports nothing at all.
