Re: Youtube throttled by TWC?

said by Anonymous_:

Also if the user is using HTML5 video player he/she will need a 8core+ system to run 1080p smoothly.

My laptop is 2.7GHz Core2 6MB L2 overclocked from 2.5GHz
4GB ram
windows 7HP
only using a IGP but it's only 1200 x 800 14" screen

HTML5 is where I can see the exception here. Yeah, video acceleration for the players need some work still. 1080p should work fine on a 3-core CPU though, assuming one CPU is busy with handling network overhead and the OS, and the other two cores are taking care of decoding the video. 8 cores sounds like what would happen with the Original format.

Which IGP does your laptop have? If it's an Intel 4500MHD (GM45/x4500) or newer, an ATi Mobility Radeon HD 4 series or higher, or a GeForce 8M series or higher, those cards can do H.264 decoding and can almost completely eliminate the CPU usage from Flash. Make sure Hardware Acceleration is on within Flash, you have the latest GPU drivers from the manufacturer of the GPU (not the PC maker unless it's dual/switchable graphics) and enable Stagevideo if YouTube's player won't turn it on using a userscript. Won't help too much with the HTML5 players though, those still need CPU.

The older GPUs such as x3100s from Intel, NVIDIA GeForce 7 series and ATi Radeon HD 3 series and older, while they can do some H.264 acceleration and other methods of accelerating HD video, they aren't quite as effective.

Ah, ok. The 965 won't get you too far with acceleration of video. Pretty basic card. The GeForce cards however should be able to take the heavy workloads off of the CPU, no problem.

With YouTube try &wmode=direct in the URL which turns on Stagevideo if you've got updated Flash and drivers. The YousableTubeFix Greasemoneky script, which is one I use can also force it on if it can even be done.

Ah, ok. So you're speaking of the chipset and not the GPU itself.

I've attached a screenshot of what StageVideo does. This video's in 720p running on one of our desktop which runs Windows Vista and an Intel Q6600 as the CPU with a Radeon HD 5770 as the GPU. There are other YouTube videos loaded in the background, but there's my CPU usage during playback.

Intel 82GM965 Graphics and Memory Controller

according the intel's documents it's x3100 IGP controller.

75% to 80% CPU usage when Forced full CPU speed & overclocked to 2.7GHz T9300 and with the &wmode=direct tag used

70% to 85% tag not used when load and playing

the CPU usage did drop to 65% when it was done downloading

usage on the 9600m GS was 40% no tag (2.53 P8700)

Something I noticed is SOME computers have issues with buffering. no matter what the specs of the computer
