svt-av1

> No word on what their encoding toolset is. They're using ST-AV1[1], the encoder they've collaborated with Intel on.[2][3] [1] https://github.com/OpenVisualCloud/SVT-AV1 [2] https://newsroom.intel.com/news/intel-netflix-deliver-av1-sc...

AV1 is a video format. SVT-AV1 [0] is a codec, and it is (co-)authored by Intel. [0] https://github.com/OpenVisualCloud/SVT-AV1

Here are six AV1 software encoders I'm aware of: 1. Alliance for Open Media's libaom: https://aomedia.googlesource.com/aom/ 2. Intel's SVT-AV1. A highly scalable AV1 encoder. It will use as many cores as you can give it. Netflix is also working on it: https://github.com/OpenVisualCloud/SVT-AV1 3. Mozilla's rav1e encoder. Implemented in Rust. Vimeo is also contributing to it: https://github.com/xiph/rav1e 4. Cisco AV1. Closed source. It's the best live encoder yet shown. Only takes it about one and a half cores on a recent laptop to do a live AV1 video call at 1080p30, both encoding and decoding: https://vimeo.com/344366650 5. EVE-AV1. Closed source from Two Orioles (https://www.twoorioles.com/). It's aiming to be the best quality AV1 encoder available: https://vimeo.com/344663992 6. Visionular Aurora (https://www.visionular.com/). Closed

> Does anyone here know a way that I could help? You could test Intel's SVT-AV1 encoder and report any issues to them. SVT-AV1 will scale to as many cores as you can give it. It's still quite fragile and buggy, but in fairness it's only at version 0.6: https://github.com/OpenVisualCloud/SVT-AV1

> Netflix/Google don't care so much about encode time And yet Netflix is working on SVT-AV1 with Intel, which is one of the fastest AV1 encoders available: https://medium.com/netflix-techblog/introducing-svt-av1-a-sc... https://www.reddit.com/r/AV1/comments/bxn2uw/svtav1_encoding... https://github.com/OpenVisualCloud/SVT-AV1 How does that fit with your narrative?

Use Intel's AV1 encoder for more speed: https://www.phoronix.com/scan.php?page=news_item&px=SVT-AV1-... https://github.com/OpenVisualCloud/SVT-AV1

> it's too complex for CPU encoding in real-time It depends on the encoder though. The AOM encoder is still quite slow, but Intel's SVT-AV1 encoder (https://github.com/OpenVisualCloud/SVT-AV1) is achieving 20 frames a second: https://www.phoronix.com/scan.php?page=news_item&px=SVT-AV1-... Xiph's rav1e encoder (https://github.com/xiph/rav1e) can do realtime encoding on a laptop at low resolutions: https://youtu.be/qubPzBcYCTw?t=2076 You always have to consider encode time versus image quality versus bandwidth. Twitch is using NGCodec's FPGA based VP9 encoders to live stream with the same image quality at a lower bitrate than H.264 can achieve: https://blog.twitch.tv/how-does-vp9-deliver-value-for-twitch...

> AV1 can't take advantage of multi-threading the same way x264 and x265 can. Neither for encoding nor for decoding. Dav1d is an AV1 decoder which takes advantage of multi-threading: https://code.videolan.org/videolan/dav1d https://medium.com/@ewoutterhoeven/dav1d-0-1-0-release-the-f... BitMovin and Intel both have AV1 encoders which can take advantage of multiple cores. BitMovin demonstrated live AV1 video almost two years ago: https://bitmovin.com/bitmovin-supports-av1-encoding-vod-live... https://bitmovin.com/constantly-evolving-video-landscape-dis... https://github.com/OpenVisualCloud/SVT-AV1

Digging in a little, based on similarities in the readme and the mailing list being the same, it appears to be related to Intel[1]. Looks to be an extension of Intel's Visual Cloud Computing efforts[2]. Edit: Feeling dumb, but confirmed, Intel is also in the license[3] :) [1]: https://github.com/intel/SVT-HEVC [2]: https://www.intel.com/content/www/us/en/cloud-computing/visu...
