Not much, but good enough to play with it in the wild.Īmong desktop players at least VLC and mpv builds for Windows support videos in AV1 format. Unfortunately not in Edge and Safari yet. WebM formats are traditionally targeting the Web platform, so what browsers can play it? According to caniuse website, AV1 is supported in latest Firefox Nightly behind a flag, and in Chrome 69+ out of the box. To encode AV1 video simply run webm -i in.mkv -av1 However it also has interactive mode for cut and crop using scriptable mpv player. Webm.py provides command-line interface so it’s mostly useful for batch encodes or usage on server. (Make sure to check Add to PATH option in Python for Windows installer.) You will have latest stable version installed along with handy webm command. However, if you have pip available, by running pip install webm So it’s easy to just drop that file on any machine you want and start using right away.
webm.py will do that for you.Īnother nice thing about webm.py is that it works in both Python 2 and 3 (Python 2 is often the only Python installed on computer even today), doesn’t have any dependencies except ffmpeg executable in PATH and contained in single source file. For example you don’t have to deal with running commands twice for 2-pass encoding or calculating bitrate by hand if you want to reach specific target file size. The first tool, webm.py is written in Python and provides simple wrapper around ffmpeg with useful defaults. So I went ahead and implement support in my tools right away, even while it’s still a bleeding edge technology. The compression efficiency and planned hardware support of AV1 looks fantastic, it should be really beneficial to add to any modern converter. You can read about technologies used in AV1 in this paper, some test comparisions with competitive solutions are available here. It was made by a collaboration of large IT companies such as Google, Mozilla and Netflix called AOMedia and first stable release was made in March of this year. In case you still haven’t heard about it, AV1 is a royalty-free modern video coding format which aims to provide better quality than alternative, patent encumbered H.265 (HEVC). Both of them work on all three major platforms (Windows, macOS, Linux) and cover typical usecases of encoding videos on demand. I’m happy to announce that my two WebM converters, webm.py (command-line) and boram (graphical) now support encoding to the new AV1 video format, starting with versions 0.12.0 and 0.5.0 accordingly.
