Google Chrome - wysokie użycie procesora podczas oglądania video

Korzystam z przeglądarki Google Chrome 94.0.4606.81 na Windows 7 Home Premium (x64).
Sprzęt również nie jest najmocniejszy: konfiguracja.
Zauważyłem, że od jakiegoś czasu, podczas oglądania video o rozdzielczości równej bądź większej 1080p zużycie procesora przez proces chrome.exe wzrasta do kilkudziesięciu procent.
Przypuszczam, że to chyba przez planowane porzucenie wsparcia dla H264 i wymuszenie obsługi VP8 i VP9.
Dla YouTube jest rozszerzenie h264ify, które spełnia swoje zadanie, ale na innych stronach nie działa. Jak więc sobie z tym poradzić?

Dorzucam raport z chrome://gpu:

Jak w procesorze psuje się „krzem” (tzw. realne zużycie) to może problem rozwiąże się gdy cpu pewnego dnia będzie nadawało się do utylizacji.

H264ify ma niby na github wątek/pr zezwalające na pracę w większej grupie domen.
Może wystarczy wyłączyć limitację pod kilka domen i użyć najbardziej poprawionej wersji kodu od kiedy w 2019 oryginalny autor ogłosił, że nie ma czasu (ale może kupił wózek zawczasu :baby: :baby_bottle: :baby_symbol:).

Gorzej jak domena nie ma do zaoferowania innego formatu niż VP8/VP9.

Google wymusza VP9 dla YT bo zwyczajnie im się to opłaca (mniejszy transfer=niższe koszty)
Oczywiście nie jest to w interesie użytkowników ze starszym sprzętem.
Nie zapowiada się jednak, aby YouTube zrezygnował ze wsparcia H.264 (Prędzej VP9 zastąpi AV1).
Zbyt dużo starych urządzeń obsługuje tylko H.264.

Podobnie jest z Twoim urządzeniem, sprzętowo dekodowanie H.264 jest możliwe, VP9 już nie.
Szczerze mówiąc nie wiem czy jesteś w stanie z tym cokolwiek zrobić.
Jeśli treść na stronie będzie dostępna jedynie w VP9 to po prostu dekodowanie będzie obsłużone programowo przez CPU i przy wyższym bitrate/rozdzielczości może występować zacinanie.

10 letni procek, konkurujący ze współczesnymi Atomami i prawdopodobnie bez części kodeków… czyli NORMA. :slight_smile:

@MatX1, z tego, co pamiętam, to gdy VP8/VP9 w Chrome były w fazie testowej, była możliwość wyłączenia ich obsługi poprzez flagi. Teraz niestety nie widzę takiej możliwości.

Dla Firefoxa jest dodatek, który powinien dodawać obsługę h264 w filmach YT osadzonych na stronach

I wątek na Githubie

Flaga nie wyczaruje kawałka krzemu do dekodowania VP8/9 :wink:
Generalnie poza YT wg mnie przeglądarka powinna preferować video w formacie (np. H.264), który komputer potrafi zdekodować sprzętowo.
Jeśli tego nie robi, to być może nie ma takiego video na stronie.

Niemniej nie badałem jak to faktycznie wygląda, być może Google forsuje swój kodek wszędzie, nawet jeśli nie jest to uzasadnione interesem użytkownika.

Dlatego teraz jak mam lepsze łącze to 4k z YT oglądam wyłącznie przy pomocy MPV Playera z konfigiem ustawionym na wymuszanie H.264.
Niestety, ale od jakiegoś czasu Google przycina losowo transfer dla takich wynalazków, nawet jak się podmieni User Agent, dlatego zrobiłem skrypt, który w przypadku ograniczenia transferu spamuje zapytaniami, aż do uzyskania normalnej prędkości :wink:

Nie jest to możliwe, YouTube nie udostępnia 4K w H.264 :wink:
H.264 jest dla wersji 1080p i niżej.

Ale on flagi potrzebuje by wyłączyć pozytywnie zakończony eksperyment i najwyżej przyjąć na klatę errory „brak wspieranej wersji wideo”.

Raczej logiczne, że jak coś zdało test, to ma flagę i przełącznik (typu „wyłącznik”) do uruchamiania z konsoli usuwany z kodu.

Faktycznie wymusza mi AV1 dla 4k. Nie zauważyłem wcześniej, bo łącze które mi umożliwia tą rozdziałkę mam od niedawna dopiero.
