I open a new thread on av1_vaapi because the other one is only about Intel drivers. I put the results of my system ffmpeg and CinGG's internal ffmpeg. $ ffmpeg -encoders | grep av1 V....D libaom-av1 libaom AV1 (codec av1) V....D librav1e librav1e AV1 (codec av1) V..... libsvtav1 SVT-AV1(Scalable Video Technology for AV1) encoder (codec av1) V....D av1_nvenc NVIDIA NVENC av1 encoder (codec av1) V..... av1_qsv AV1 (Intel Quick Sync Video acceleration) (codec av1) V....D av1_amf AMD AMF AV1 encoder (codec av1) V....D av1_vaapi AV1 (VAAPI) (codec av1) A....D wmav1 Windows Media Audio 1 $ /home/paz/cinelerra5/cinelerra-5.1/thirdparty/ffmpeg-6.1/ffmpeg -encoders | grep av1 V....D libaom-av1 libaom AV1 (codec av1) V....D av1_vaapi AV1 (VAAPI) (codec av1) A....D wmav1 Windows Media Audio 1 On my system libva is at version 2.20.0; I don't know how to see the version of libva used internally by CinGG (if any). I guess, as Andrew says, internal libva is out of date, or use the system one directly. Important missing, besides the Intel ones, is av1_nvenc. I don't know if it depends on my system which is AMD and therefore doesn't have Cuda, or you have to manually enable the library. I see that Phyllis' system has only two libraries for av1 and all the others are missing. I additionally have only av1_vaapi. @Terje, you also use a rolling, can you see the encoders of CinGG's internal ffmpeg and the system libva version? I am attaching a new version of the preset for av1_vaapi, but there are many conditions for it to work: you have to install CinGG (appimage is no good, unless you know how to open and recreate it); new generation GPU (Nvidia 4000; AMD Radeon 7000; Intel Xe 2 or Intel Arc); system with updated libva (possibly Rolling...). If anyone meets the requirements, I would like to know if the preset works or what errors it gives. I used average options between quality and speed but could not test them because I lack the right hardware.
