Already touched this topic barely in another thread<br>
<a href="https://lists.cinelerra-gg.org/pipermail/cin/2023-December/007346.html" target="_blank" rel="noreferrer">https://lists.cinelerra-gg.org/pipermail/cin/2023-December/007346.html</a><br>

But so many SW and HW pieces are mentioned around, it is almost a
full-time reading and study:<br>
VAAPI, MESA, VULKAN, Intel Quick Sync Video etc......<br>
<br>
I realize my aging hardware which is fast enough for other tasks,
needs some "AV1 upgrade", if possible.<br>
<br>
But first I wonder, what is expected possible to do (obtain) with
AV1 de-/encoding on my existing 64bit hardware:<br>
<br>
<blockquote><font face="monospace">1) laptop 2018: Dell XPS 13-9370:
quad core i7-8550U CPU (8. gen Kabylake) and Intel UHD Graphics</font><br>
<br>
<font face="monospace">2) WS infinity: MSI Z170A mobo: quad core
i7-6700K CPU (6. gen Skylake), NVIDIA GeForce GT-730 graphics</font><br>
</blockquote>
<br>
A budget friendly first "AV1 HW upgrade" of the workstation 2) if
possible, would be to add a new GPU as Intel Arc A380.<br>
But the question is if this will work at all on that much older
(2015) Skylake platform with i7-6700K CPU?<br>
I've seen CPU bottlenecks has been mentioned and that Arc A380 is
targeted at newer generations CPU ...</div></blockquote></div></div><div dir="auto"><br></div><div dir="auto">I digged up this:</div><div dir="auto"><br></div><div dir="auto"><a href="https://community.intel.com/t5/Media-Intel-Video-Processing/ffmpeg-6-using-qsv-on-ARC380/m-p/1524165/emcs_t/S2h8ZW1haWx8dG9waWNfc3Vic2NyaXB0aW9ufExNS0o5N1ZLMzlUMkRIfDE1MjQxNjV8U1VCU0NSSVBUSU9OU3xoSw">https://community.intel.com/t5/Media-Intel-Video-Processing/ffmpeg-6-using-qsv-on-ARC380/m-p/1524165/emcs_t/S2h8ZW1haWx8dG9waWNfc3Vic2NyaXB0aW9ufExNS0o5N1ZLMzlUMkRIfDE1MjQxNjV8U1VCU0NSSVBUSU9OU3xoSw</a><br></div><div dir="auto"><br></div><div dir="auto">url is ...eeeh.</div><div dir="auto"><br></div><div dir="auto">I hope vaapi/qsv by themselves does not consume too much cpu during video operations.
