GripNews🌕 讓 rav1d 視訊解碼器提速 1% ➤ 透過分析和優化，提升 AV1 解碼器的效率 ✤ <a href="https://ohadravid.github.io/posts/2025-05-rav1d-faster/" rel="nofollow noopener" translate="no" target="_blank">https://ohadravid.github.io/posts/2025-05-rav1d-faster/</a> 這篇文章記錄了作者嘗試優化 Rust 版本的 AV1 視訊解碼器 rav1d 性能的過程。作者參與了 memorysafety.org 舉辦的性能提升競賽，透過分析 profiler 的資料，發現了兩個小的性能瓶頸，並針對其中一個瓶頸進行了優化，成功將解碼速度提升了略高於 1%，且未使用任何不安全的程式碼。優化重點集中在 cdef 濾鏡的實現上，發現 rav1d 使用了較大的暫存緩衝區來歸零，而 C 版本的 dav1d 則使用更精簡的方式。 + 這篇文章很棒！詳細解釋瞭如何透過分析性能瓶頸，並針對性地進行優化，即使是很小的改進也能帶來實際的效能提升。 + 令人印象深刻的是作者在未使用不安全程式碼的前提下完成了優化，這對於 Rust 語言來說尤其重要，也證明瞭 Rust 在性能上的潛力。 <a href="https://mastodon.social/tags/%E8%A6%96%E8%A8%8A%E8%A7%A3%E7%A2%BC" class="mention hashtag" rel="nofollow noopener" target="_blank">#視訊解碼</a> <a href="https://mastodon.social/tags/%E6%80%A7%E8%83%BD%E5%84%AA%E5%8C%96" class="mention hashtag" rel="nofollow noopener" target="_blank">#性能優化</a> <a href="https://mastodon.social/tags/Rust" class="mention hashtag" rel="nofollow noopener" target="_blank">#Rust</a> <a href="https://mastodon.social/tags/AV1" class="mention hashtag" rel="nofollow noopener" target="_blank">#AV1</a>

MikaDone this with the <a href="https://sakurajima.social/tags/AMD" rel="nofollow noopener" target="_blank">#AMD</a> 5600G's iGPU, now testing <a href="https://sakurajima.social/tags/Jellyfin" rel="nofollow noopener" target="_blank">#Jellyfin</a> hardware transcoding with my <a href="https://sakurajima.social/tags/Intel" rel="nofollow noopener" target="_blank">#Intel</a> <a href="https://sakurajima.social/tags/ArcA380" rel="nofollow noopener" target="_blank">#ArcA380</a> GPU - one question though, is it normal for CPU usage to be rather high at least in the early parts of streaming (while transcoding), even with hardware transcoding? I'm just trying to figure out if it is actually hardware transcoding - I'm assuming it is, bcos on the admin dashboard I'm seeing that it's transcoding as AV1 and I'm sure my Ryzen 7 1700 would not be able to do/handle that, esp considering that I'm testing with 4 streams playing concurrently? but the CPU usage is rather high the first minute or two or more from when the stream starts, it does lower down afterwards - the video playback is perfectly fine, no stuttering or anything like that. My method of passthrough is the same as I did with the 5600G, that is a simple passthrough to the <a href="https://sakurajima.social/tags/LXC" rel="nofollow noopener" target="_blank">#LXC</a> container, then to the <a href="https://sakurajima.social/tags/Docker" rel="nofollow noopener" target="_blank">#Docker</a> container running Jellyfin. I don't think I noticed this high CPU usage when testing the 5600G, and the only minor configuration difference between the two was I'd used <a href="https://sakurajima.social/tags/VAAPI" rel="nofollow noopener" target="_blank">#VAAPI</a> with the 5600G and disabled <a href="https://sakurajima.social/tags/AV1" rel="nofollow noopener" target="_blank">#AV1</a> encoding (since idt it supports it), while on the Arc A380 GPU I'm using Intel's <a href="https://sakurajima.social/tags/QSV" rel="nofollow noopener" target="_blank">#QSV</a> and have enabled AV1 encoding. Am I correct to assume that hardware transcoding is indeed working? Cos again, I'm quite certain my Ryzen 7 1700 would definitely NOT be able to handle this lol esp since I only give the LXC container 2 cores.

Gianni RosatoUpdated numbers for Eve-AV1 & Eve-VP9 are public! The last time they were updated was around 2019, so this should give a more relevant look at how they perform.

Scott LairdI'm doing some <a href="https://hachyderm.io/tags/AV1" class="mention hashtag" rel="nofollow noopener" target="_blank">#AV1</a> encoder testing in ffmpeg. So far, SVT-AV1 seems way, *way* better than av1_nvenc (nVidia's hardware-offloaded encoder).It's not so much that it looks better at a lower bitrate (but it does), but it's also *faster*, somehow. Kinda confused here right now.nVidia 4090 vs AMD 5975WX, so not the *fastest* available, but pretty zippy.
