[Feature Request] Use Specific Codec #16

Closed HDark15 closed 2 years ago

HDark15 commented 2 years ago

Can something like this be implemented? https://github.com/alextrv/enhanced-h264ify

raingart commented 2 years ago

No, It is Immpossible. The reason is that the video on Youtube servers is already stored in H264 format (max 720p). The resolution above it already uses VP9/AV1. The reason is that AV1 encoded video uses less space on the server. Which reduces overhead (storage and delivery) to Google servers.

The only way to watch videos in a large resolution. This is to use an external player that will play the downloaded video file with the youtube-dl library.

If your system is a little outdated, then it might be worth making sure that you have hardware video decoding enabled. Screenshot from 2022-09-03 17-10-56

I can watch VP9/AV1 video, the reason I'm using this extension because it's faster and less CPU usage for my weak CPU. The downside I can only watch video up to 1080p 60fps and that's okay because it can't handle anything higher. A lot of people using this just to gain more performance, I just thought it can be useful to be implemented to your extension that already give user more control. Thank you for replying.

The only thing h264ify does is block youtube from sending a response to a request for a supported video format. That is, the extension simply makes the browser pretend that the device does not support anything other than H264.

Nothing more can be done. Of course, I can just paste the code into the plugin, but why? The problem is that Nova starts up slower than the extension. And it just won't work right.

Yeah I know, thanks for helping me

Sorry, I don't want to open this but. Why are you kept telling me how the h264ify works? I know what it does, maybe I'm not clear enough. H264 codec use less CPU usage.

As I understand it the question - "was whether it is possible to implement a similar mechanism that will use hardware acceleration instead of software"?

I tried to convey that there is only one way known to me. And it has already been implemented. I do not know your knowledge and therefore tried to explain the theory, a possible solution and how it works.

It was probably right to simply say "No, I will not implement." what they are trying to explain. People do not want to delve into, they are lazy. They need ready solutions. I just started to forget about it.

If you want a magical solution to a problem then try these scripts: https://greasyfork.org/en/scripts?q=cpu+youtube

But without explaining how they work. After all, the main thing is to believe and not to know the truth.
