Already touched this topic barely in another thread https://lists.cinelerra-gg.org/pipermail/cin/2023-December/007346.html
But so many SW and HW pieces are mentioned around, it is almost a full-time reading and study: VAAPI, MESA, VULKAN, Intel Quick Sync Video etc......
I realize my aging hardware which is fast enough for other tasks, needs some "AV1 upgrade", if possible.
But first I wonder, what is expected possible to do (obtain) with AV1 de-/encoding on my existing 64bit hardware:
1) laptop 2018: Dell XPS 13-9370: quad core i7-8550U CPU (8. gen Kabylake) and Intel UHD Graphics
2) WS infinity: MSI Z170A mobo: quad core i7-6700K CPU (6. gen Skylake), NVIDIA GeForce GT-730 graphics
I continue the "AV1 de-/encoding on my existing 64bit hardware" question above as a branch here (instead of a new related thread).
This part is also related to another 2021 thread, [Cin] tried to update av1.webm profile https://www.mail-archive.com/[email protected]/msg02804.html which refere to FFmpeg's AV1 Video Encoding Guide https://trac.ffmpeg.org/wiki/Encode/AV1
I took my first AV1 rendering test with CinGGs default av1.webm preset by loading a standard SD DV file clip. du -sh dv* 389M dv01_07.dv 30M dv01_07.webm ffprobe -hide_banner dv01_07.dv [dv @ 0x5595e79b4580] Estimating duration from bitrate, this may be inaccurate Input #0, dv, from 'dv01_07.dv': Metadata: timecode : 01:09:35:09 Duration: 00:01:53.28, start: 0.000000, bitrate: 28800 kb/s Stream #0:0: Video: dvvideo, yuv420p, 720x576 [SAR 16:15 DAR 4:3], 25000 kb/s, 25 fps, 25 tbr, 25 tbn, 25 tbc Stream #0:1: Audio: pcm_s16le, 48000 Hz, stereo, s16, 1536 kb/s ffprobe -hide_banner dv01_07.webm [libdav1d @ 0x560ccddb3380] libdav1d 1.0.0 Input #0, matroska,webm, from 'dv01_07.webm': Metadata: ENCODER : Lavf60.16.100 Duration: 00:01:53.28, start: 0.000000, bitrate: 2220 kb/s Stream #0:0: Video: av1 (Main), yuv420p(tv, bt470bg/unknown/unknown), 720x576 [SAR 1:1 DAR 5:4], 25 fps, 25 tbr, 1k tbn, 1k tbc Metadata: DURATION : 00:01:53.243000000 Stream #0:1: Audio: vorbis, 48000 Hz, stereo, fltp Metadata: DURATION : 00:01:53.281000000 Rendering took 0:03:33 or 1.87 x the Duration This webm file was displayed ok in VLC and FFplay on Leap 15.5
To start with the workstation 2) above, I want suggestions how to test the possible AV1 encoding options (libaom, SVT-AV1, MESA, VAAPI, VDPAU) using my system enabled ffmpeg 6.0.1 commands,, and also suggestions to required change in system/graphics settings.
System output as background info:
fmpeg -encoders -hide_banner | grep av1 V....D libaom-av1 libaom AV1 (codec av1) V....D librav1e librav1e AV1 (codec av1)
From phoronix articles librav1e and SVT-AV1 should be faster, but sometimes at quality cost.
Sorry, not tried them personally due to svt demanding 64-bit system and rav1e demanding rust.
So for this task you are on your own .. sorry!
https://ottverse.com/analysis-of-svt-av1-presets-and-crf-values/
may be crf 26 (ish) and preset 6 ?
On 36 core machine with avx512 it surely was fast, but on 4c .. I guess 1.25 fps or so will be best you can get? (for fullhd source)
