Overview

Product summary

Review the store description, core capabilities, and common use cases.

enhanced-h264ify is a fork of well-known h264ify extension for Firefox/Chrome which blocks VP8/VP9 codecs on YouTube, so that you can use H264 only. This may be useful because there are lots of devices on the market which support H264 hardware decoding and do not support VP8/VP9.

This extension has new features such as manual blocking of H264, VP8, VP9, AV1, Opus, AAC codecs and 60fps video. By default it blocks everything but H264 and 60fps video.

It works only on YouTube.

Improved video quality on AV1 YouTube videos. By blocking AV1, YT will use VP9, resulting in a higher bitrate look!

Perfect for NVIDIA Linux since it doesnt support AV1, only VP9

Игорь2025年11月24日

В последние недели Youtube перевел трансляцию роликов в av1 кодеке, убрал возможность настройки VP9, а мой процессор не имеет аппаратную поддержку AV1. Загрузка процессора при просмотре ютуб сильно возросла. Это расширение исправило эту ситуацию. Спасибо разработчику

AI product read

Allow users to choose which video and audio codecs YouTube plays by blocking specific codecs (H.264, VP8, VP9, AV1, Opus, AAC) and optionally blocking 60fps video

Many devices support H.264 hardware decoding but do not support VP8/VP9/AV1 software decoding, causing poor YouTube playback performance. This extension forces YouTube to use H.264 by reporting unsupported codecs as unavailable.

Install extension → click extension icon to open popup with checkbox options for each codec → check/uncheck which codecs to block → browse YouTube normally; the extension injects scripts that override canPlayType() and MediaSource.isTypeSupported() to filter out blocked codecs

Target users: Users with older hardware that has H.264 hardware decoding but lacks VP8/VP9/AV1 support / Users wanting to reduce CPU usage on YouTube by forcing hardware-accelerated codecs / Users who want manual control over YouTube's codec selection

Monetization

No paid features detected

The extension is completely free and open-source (MIT License). All features—blocking H.264, VP8, VP9, AV1, Opus, AAC codecs, blocking 60fps video, and disabling Loudness Normalization—are available to all users without any gating. The store description mentions a voluntary Ko-fi donation link for supporting the developer, but this is not part of the extension itself and does not gate any functionality.

Confidence: 100
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension operates entirely locally using chrome.storage.local and localStorage to store user codec preferences. No authentication, account creation, or external service login is required. No API calls to external services are made. The extension only injects scripts into YouTube pages to override canPlayType() and MediaSource.isTypeSupported().
