AV1 Video Extensions is a premium video utility PC program by developer Yellow Elephant Productions. It is a codec pack that provides the necessary libraries and prerequisites to open and view AOMedia Video 1(AV1) format videos. It serves as a companion add-on for the developer’s all-in-one multimedia playback solution called Media Player.

Codec add-on

In a nutshell, AV1 Video Extensions enable playback support for files in AV1 format. It’s a video codec that’s primarily used for transmitting media over the internet, favored for its impressive compression capabilities, which provide high-quality videos at lower bitrates. Installation is quite easy and straightforward since you don’t need to do any additional setup or configuration. Just open your desired file, and it will automatically play right away.

As hinted earlier, this codec pack is proprietary and will only work with the Media Player app and nothing else. All that said, the actual video playback and viewing experience falls a bit short, given the inconsistent performance and occasional app crashes. Hopefully, these will be addressed promptly in the future.

A decent value-add

All in all, if you use the aforementioned Media Player for your playback needs and find yourself unable to open and view AV1 files, the AV1 Video Extensions app is a must to help fix your issue. It’s a breeze to install and work right away. Once the issues stated above are dealt with, using it will be a lot better.
