The popular cross-platform, open-source video player VLC has received a significant update in 3.0, the first in what will be called the Vetinari branch. It adds support for HDR, including both 10-bit and 12-bit color and 360-degree video.
This release version now also fully supports Chromecast streaming, a feature we first played with back in 2016. While VLC is open source, this part of it isn't; Tom's Hardware reports that VideoLAN explained it "used Google’s official closed-source SDK to build out the feature, which prevents it from releasing the source."
Other major added features include 3D audio support, audio passthrough for HD audio codecs, and support for browsing NAS drives. As always, a bunch of new codecs are supported too.
