You'll need recent ffmpeg (4.3+) to avail many of these. These libs are libaom, libdav1d and various hardware-accelerated decoders such as nvdec. However, multiple external decoder libraries are supported via wrappers. For example, if I want to preserve detail. There is no native (software) decoder for AV1 in FFmpeg as of v4.4.
This guide currently focuses on libaom and SVT-AV1. There are currently three AV1 encoders supported by FFmpeg: libaom (invoked with libaom-av1 in FFmpeg), SVT-AV1 ( libsvtav1 ), and rav1e ( librav1e ). But one thing x265 does better than any AV1 encoder is to allow the user to preserve fine detail if they so choose. Depending on the use case, AV1 can achieve about 30 higher compression efficiency than VP9, and about 50 higher efficiency than H.264. The former is faster and outputs more efficient video.) Thats greatthree cheers for the codec and the encoder developers. A Google Compute Engine n2-standard-16 (16 vCPU’s, 64 GB memory) Cascade Lake instance running Ubuntu 18. (Compare SVT-AV1 preset 8 to x265 presets veryslow-medium.The media-autobuild_suite also supports SVT-AV1 for FFmpeg builds with the SVT-AV1 patch. The AV1 codec also has tuning mechanisms, with tuning for peak signal-to-noise ratio (PSNR) and SSIM available for a few versions, and tuning for VMAF relatively new.
Pre-compiled 64-bit Windows executables can be found on AppVeyor. Plugins (patches) for FFmpeg and Gstreamer are also available. Motivation While trying to try out the latest features for the libaom AV1 encoder. Overnight encoding of hour-long video’s, comes within reach on most high-end machines using enc-mode 4, and even on mid-range machines using enc-mode 6 or higher.īuild instructions can be found in the SVT-AV1 repository. Now Available: Weekly build of libaom AV1 + FFmpeg docker image. While SVT-AV1 is still in heavy development, it already reached a point that it delivers better quality at identical bit-rates at higher speeds on multi-core machines. The ff tools have a -bsf option applied per stream, taking a comma-separated list of filters, whose parameters follow the filter name after a ’’.
