Enhanced-h264ify is a Chrome extension that allows you to choose the video codec that YouTube plays for you. Developed by alex, this free browser add-on falls under the category of Browsers and the subcategory of Add-ons & Tools.

This extension is a fork of the well-known h264ify extension for Firefox/Chrome, with the added feature of blocking VP8/VP9 codecs on YouTube. This is particularly useful for devices that support H264 hardware decoding but do not support VP8/VP9 codecs. By default, enhanced-h264ify blocks all codecs except H264 and 60fps video.

In addition to blocking VP8/VP9 codecs, enhanced-h264ify offers manual blocking of H264, VP8, VP9, and AV1 codecs, allowing you to customize your YouTube experience. It is important to note that this extension is specifically designed to work only on YouTube.
