It seems you better use "-intra-period 30 -irefresh-type 2 " parameters for SvtAv1EncApp see https://github.com/OpenVisualCloud/SVT-AV1/issues/257 and https://trac.ffmpeg.org/ticket/7913 additionally, you can try to set libaom-av1 into speed mode by using cpu-used parameter - "0" is slower, "8" is fastest. Try "cpu-used" 5, according to graph at https://www.streamingmedia.com/Articles/ReadArticle.aspx?ArticleID=130284 libaom-git speed changes graph: https://www.reddit.com/r/AV1/comments/bpp15r/monthly_changes_in_the_speed_an... still in 0.1 fps range for high-quality (cpu-used=1), 1080p encodings on Ryzen 2400G ---------- Пересланное сообщение ---------- Тема: SVT-AV1 0.5 Дата: Воскресенье 19 мая 2019 Отправитель: Andrew Randrianasulu <[email protected]> Получатель: "Cinelerra.GG" <[email protected]> Hello, all!! Just read news at Phoronix: https://www.phoronix.com/scan.php?page=news_item&px=SVT-AV1-0.5.0-Released ------- SVT-AV1 0.5 is easily one of the fastest AV1 CPU-based video encoders and has been performing excellent in our tests, including continued daily benchmarks of it in keeping track of its performance. This open-source AV1 video encoder as of the v0.5 release supports 8/10-bit 4:2:0 encoding up to 4k60p resolutions, various presets, FFmpeg and GStreamer plug-in support, rate control support, various filters, tiling, 4/5 layer prediction structures, multi-reference picture support, and other features. -------- so I downloaded their release, and tried to build and test it on cat /proc/cpuinfo processor : 0 vendor_id : AuthenticAMD cpu family : 21 model : 2 model name : AMD FX(tm)-4300 Quad-Core Processor stepping : 0 microcode : 0x6000852 cpu MHz : 1811.199 cache size : 2048 KB physical id : 0 siblings : 4 core id : 0 cpu cores : 2 apicid : 16 initial apicid : 0 fpu : yes fpu_exception : yes cpuid level : 13 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt pdpe1gb rdtscp lm constant_tsc rep_good nopl nonstop_tsc cpuid extd_apicid aperfmperf pni pclmulqdq monitor ssse3 fma cx16 sse4_1 sse4_2 popcnt aes xsave avx f16c lahf_lm cmp_legacy svm extapic cr8_legacy abm sse4a misalignsse 3dnowprefetch osvw ibs xop skinit wdt lwp fma4 tce nodeid_msr tbm topoext perfctr_core perfctr_nb cpb hw_pstate ssbd vmmcall bmi1 arat npt lbrv svm_lock nrip_save tsc_scale vmcb_clean flushbyasid decodeassists pausefilter pfthreshold bugs : fxsave_leak sysret_ss_attrs null_seg spectre_v1 spectre_v2 spec_store_bypass bogomips : 7599.47 TLB size : 1536 4K pages clflush size : 64 cache_alignment : 64 address sizes : 48 bits physical, 48 bits virtual power management: ts ttp tm 100mhzsteps hwpstate cpb eff_freq_ro ffmpeg patch apparently for 4.1 branch, and whole software failed to build on 32-bit oS, yet it was ok on 64-bit Slackware 14.2 (gcc 5.5.0, yasm 1.3.0, cmake) root@slax:~/src/SVT-AV1-0.5.0/Bin/Release# ffmpeg -i /home/guest/20160802_185428.MOV -nostdin -f rawvideo -pix_fmt yuv420p -

Not bad ... next, I used ffmpeg-git for copying frames into mp4 container ffmpeg -i out.ivy -vcodec copy av1_svt_0.5.mp4 Resulting file was playable in my libdav1d patched Cinelerra-GG :} Also, libdav1d saw minor release 0.3.1 - featuring version for 0.3.1 · May 11, 2019 dav1d 0.3.1 'Sailfish', the fast and small AV1 decoder This is a small bugfix release fixing a decoding issue on SSSE3 CPU, when frame-threading is activated. It also reduces the binary size and gives more optimizations for SSSE3 src: https://code.videolan.org/videolan/dav1d/tags/0.3.1 -------------------------------------------------------
