If I take a look at the numbers of media elements Netflix offers, the amount is just huge, and I really don't understand how they did it. As with VP9, it’s OK to use the fastest preset (8) with the first pass it’s. The default value is 1, which will be slow and high quality. The valid range is from 0 to 8, higher numbers indicating greater speed and lower quality. Recently I came along a news article about Netflix and that they are upgrading their library to AV1. According to the FFmpeg documentation, the switch cpu-used Set s the quality/encoding speed tradeoff.

No matter which one of these I try, the performance is slow, even slower than with HEVC. You will notice that there are 3 main encoders available to handle encoding to av1.

If you take a look at the following doc pages from ffmpeg: You just have to download a recent static master build until ffmpeg starts releasing. Disclaimer: does not claim that TRISTAN AV1 LLC is an actual trucking company or broker.

pixfmt yuv422p10le is also accepted but produces file not playbale in mpv or vlc. SvtAv1EncApp -i stdin -n 300 -w 1920 -h 1080 -b out.mp4 Fast encoding, crap quality, generates ivf output, not mp4. After building it, first try ffmpeg -i /mnt/d/output/input.mov -nostdin -f rawvideo -pixfmt yuv420p. That was the point where things started to get strange, as I want to have this codec instead of h264 ^^. The one used by netflix is called SVT-AV1. Yesterday I started implementing AV1 as codec, as it will in near future detach h264 as it's more efficient with the same level of compatibility across all the available browsers. This VA-API AV1 support for FFmpeg is on top of many other FFmpeg feature additions in recent months. The Intel-contributed work was merged on Monday.

Further information is available in the libvpx API documentation. The FFmpeg patch we talked about back in September has now been merged for allowing AV1 decode over the VA-API interface with this widely-used multimedia library. To get more documentation of the libvpx options, invoke the command ffmpeg -h encoderlibvpx, ffmpeg -h encoderlibvpx-vp9 or vpxenc -help. To enable streaming, I take the input video and re-convert it into HLS segments in multiple version and codecs to reach maximum compatibility. For the documentation of the undocumented generic options, see the Codec Options chapter. I'm developing a VoD application as a white label product that runs in a SaaS context using K8s.
