Choose what video and audio codecs YouTube should play for you

Latest reviews

• (2025-07-09) Joey Tatú: I was having issues playing YouTube videos. The video and audio would stutter and it would be difficult to understand and watch. I right-clicked the video and selected "Stats for nerds" and saw it was using VP9 encoding. With this extension, I blocked VP8 and VP9 encoding. Now, YouTube videos are using AV1 encoding and play without issues. Definitely recommend.

• (2025-06-27) Lilith: Good but you should rename it to block/enhanced ytb codec I'm using it to force av1
• (2025-06-11) K S: Doesn't work
• (2025-05-16) Robert Wedel: I have no idea what this extension does, but since I installed it on my Windows 10 PC to try to cut down on YouTube running my CPU usage up to 100%, the CPU usage of Chrome is 4th or 5th on the Task Manager meter. Right now I am running a video on YouTube and streaming a hockey game, and Chrome is using only 0.9% of the CPU. To me, this extension is the best thing since Windows 7 (RIP) and sliced bread.
• (2025-02-05) Jan Kowalski: Blocking 60fps on Youtube works.
• (2025-01-23) Regilio Karemaker: it removes higher than 720p but it can remove 60 fps i get nousious watching minecraft video's at 60 fps but 480 looks really bad now i can watch at 720 andf this is good for me
• (2024-12-16) TZ Shuhag: An amazing extension. Works as described. Thanks dev 🤍
• (2024-09-14) Anoir Ben Tanfous: I wish if there is something like that enable only and for AV1 instead... As it is a better format, I understand that some want to reduce CPU usage by taking advantage of the HW acceleration, yet they are wasting a lot of bandwidth and bargaining for a worse quality... We should go in the direction that AV1 become a DeFacto standard for web videos... or maybe VCC. I am sure developers will then put a lot more effort to make it work on almost all devices of 10 years ago by finding some new optimizations to implant here and there... Encoding already became 10x faster in the last couple of years.
• (2024-06-18) Evrins Hu: cpu usage of chrome on Macbook 14 M2 pro drop 50% when play same video on youtube
• (2024-05-30) John: great
• (2024-03-02) Matthew Chen: As an old intel Macbook user. I like it very much!! Playing YouTube video VP9 is accelerated by hardware.
• (2024-01-17) Bathtub Sessions: This is a versatile tool which gives control over what codecs will not be sent by YouTube. I use it to block sending AV1 codec. My graphics card is capable of decoding VP9 so that's the codec I get. But the icing of the cake for a person who cares about audio quality is the option to block YT from sending normalized audio streams. The sound of the not normalized streams is better; it has more details and sounds more open. I am so happy with this option.
• (2023-11-15) M. Shamim: On Orange Pi 5 using Ubuntu 22.04 for Rockchip RK3588 devices by Joshua Riek, some video resolution / aspect ratio aren't supported by AV1 hardware, so video turn green. This help fix that for the time being. I don't know if that will ever be fixed.

• (2023-06-04) Paul Johnston: Great plugin, no issues. It would be nice though if we could choose to only enable VP9 and AV1 for videos that are 1440p or higher but block those codecs for 1080p and below.

• (2023-03-30) Igor Karlos: Cumpre o prometido. Muito boa.
• (2023-03-11) Александр: На любом кодеке грузит процессор на 100%. Это обычные видео на ютуб с разрешением 720р. При переключении на 264 процессор грузит до 70-80%, но видео начинает отставать от звука и перескакивает каждые 2-3 секунды, а то и 10 секунд. В общем звук есть, а видео за ним не успевает и прыгает. Не помогло это расширение.

• (2023-01-25) Александр Чернявский: Не понимаю как некоторые пишут что не работает. У меня старенький ноутбук с одной только Intel HD Graphics 4000, которая не поддерживает ни VP-8, ни VP-9 ни тем более новый AV-1. Без этого расширения при просмотре YouTube нагрузка идёт только на CPU, и для 1080p60 может достигать до 60%. После установки расширения нагрузка на CPU не подымается выше 5%, а GPU уже нагружен на 20% в среднем. Так что расширение однозначно работает. Ещё по поводу отключения нормализации громкости, как оказалось полезно если аудиосистема не из дна. Увы пришлось всё же включать нормализацию когда родителям включаю фильмы на старом телевизоре через переходник HDMI > Тюльпаны. Без нормализации на старом телевизоре звук то еле слышно то орёт как бог знает что при одинаковой настройке громкости.

• (2022-11-21) Don't do it: This broke. Until a few days ago it was working fine, but now it is causing lag and freezing in the videos on Opera browser.

• (2022-10-29) Сергей Попов: По сути оно должно форсировать кодек, который менее затратный для компьютера. Но при включении нагрузка на CPU достигает 100%, а нагрузка на CPU не меняется. Ощущение, будто засунули майнер. Если нужна будет какая-то дополнительная информация, то напишу. P.S Использовал на Edge

• (2022-08-19) Flicsmo: Works perfectly, cuts CPU usage down to ~2/3. Highly recommended if you could use a bit more performance at the cost of a near-unnoticeable quality hit.

• (2022-07-08) Pavel Matytsin: Крайне полезное расширение для обладателей не самых новых ПК, не имеющих аппаратной поддержки VP9/AC кодеков. Позволяет принудительно отключить стриминг видео с ютуба в неподдержваемых вашей видеокартой форматах, тем самым разгрузив CPU и переложив декодирование "на плечи" GPU. Для полного успеха необходимо в командную строку в ярлыке для запуска Хрома добавить следующие ключи: --ignore-gpu-blocklist --enable-native-gpu-memory-buffers --use-angle=d3d9 --disable_d3d11_video_decoder. Если аппаратное декодирование включится то при просмотре ютуба откройте еще в одной вкладке About:media-internals и узрите использование DXVA D3D9 видеокодека: kVideoDecoderName "VDAVideoDecoder" kIsPlatformVideoDecoder true "Selected VDAVideoDecoder for video decoding, config: codec: h264, profile: h264 main.. pipeline_state "kPlaying"
• (2022-05-27) André Pereira: I finally can watch YouTube without burning my computer. Thank you so much! The temperature of the cpu got much lower with this extension installed (from 85+ to 70)
