shanaencoder现在用的av1效率低,能加入svt-av1吗,ffmpeg已支持svt-av1

这都快一年了,还是没有加是SVT-AV1。
根据已有的新闻和其他论坛的讨论,可以认为用SVT-AV1作为AV1的编码器是一大热门选择,其自带的多线程使用、支持最高AVX512指令集与其他功能使用起来十分便捷。
但是根据我目前通过ffmpeg使用libsvtav1的体验,在多线程编码中存在BUG,需要限制lp<=4,在svtav1的gitlab上亦可看到有此类问题的报告(Allocate memory failed when there is over 200GB of free memory (#1893) · Issues · Alliance for Open Media / SVT-AV1 · GitLab)。

Like you said, currently only libaom-av1 is available as an AV1 encoder in Shana. Other AV1 encoders like librav1e and libsvtav1 are not included in the ffmpeg library.
Including them amounts to a feature request. Let's see if @Rina is interested in it.
That said, I'm not sure if SVT-AV1(libsvtav1) is more efficient and effective in AV1 encoding than AOMEnc(libaom-av1) in general. Just out of curiosity, can you provide any concrete benchmarking results?![g37.gif](/modules/editor/components/emoticon/tpl/images/green/g37.gif)
