But when I tried now to render the same hdv file as with ffmpeg, Cingg failed with int FFMPEG::open_encoder(const char*, const char*): cant find codec libsvtav1:/Videoklipp/AV1/hdv09_04_m2t_svt-av1_230.webm Shouldn't Cingg be able to work with the system upgraded libSvtAv1Enc2 v. 2-3-0 automatically as well as ffmpeg does? Or if necessary via a simple "update", without complete rebuild? ------------- I had a look at my last rebuild of Cingg for using ffmpeg 7.1 : Does "disabled libsvtav1" say something? # ./configure --with-single-user --disable-static-build --without-thirdparty --without-libdpx configure: loading site script /usr/share/site/x86_64-pc-linux-gnu ..........snip checking for /usr/local/cuda/include/cuda.h... no checking cuda sdk... no checking for dlopen in -ldl... yes checking for numa_alloc in -lnuma... yes checking for openexr available... yes Reason Package ------ ------- disabled encore disabled audiofile disabled esound disabled libsvtav1 ...snip...
