Network Streaming Performance - YouTube

YouTube is one of the most popular video streaming services, and Google maintains a number of encodes for each stream. On platforms supporting Adobe Flash, FLV streams are available at resolutions ranging from 240p to 480p. HTML5 streams are either in WebM (for Firefox) or MP4 / H.264 (for Internet Explorer). WebM streams typically top out at 720p, while MP4 is the preferred format for 1080p. At higher resolutions, Adobe Flash also streams the MP4 version.

As expected, we get GPU acceleration when using Adobe Flash in Firefox on Windows 7. The debug OSD presents the requisite details.

Windows 8 has an app for YouTube, 'YouTube Player' which allows for stream quality selection. Just like the Netflix app, there is no direct way to determine if GPU acceleration is being used.

HD YouTube Streaming using the YouTube Player App on Windows 8

We will rely on the power consumption at the wall to determine the efficiency of various ways to stream YouTube videos across different operating systems. Since the matrix of options is quite big, we present the graphs one at a time. All the graphs are on the same scale. Press the button below corresponding to the combination you want to compare the current graph against.

It can be seen that the Windows 8 YouTube Player App wins hands down. The stream being decoded is, in all probability, the 1080p H.264 version. Even when Adobe Flash is being used, Windows 8 seems to be more efficient compared to Windows 7. If you are on Windows, and prefer to use HTML5, it is better to avoid Mozilla Firefox because the WebM version consumes the most power at the wall (due to lack of hardware accelerated decode) while providing only a 720p stream. Once again, if YouTube forms a major part of your HTPC experience, an upgrade from Windows 7 to Windows 8 can be recommended.

    Also, not everyone has a super smart TV. I have a 55" Sony series 9 (hx923). It's one of the best TVs money can buy (especially for may visual tastes), but it's smart platform sucks.

    I don't like to depend on a dumb machine which is what I consider TV's for things I can do 10 times better on a PC. and I've not seen a single "smart tv" platform that didn't suck monkey balls as far as usability, speed and interface design...

    I can watch any kind of video i like. Even embedded videos in a web browser. Easy way is to go to the website on my phone and then hit one button and within 2 seconds its playing on the TV. I download All the TV i want to watch from torrents. with Netflix and Sky TV im pretty much covered

    First of all, it's a fully functional PC vs extremely limited TV/small media player. That right there is difference enough. Media, gaming, productivity, limitless customization...

    As for media capabilities, there is no match for things HTPC players, renderers, filters, codecs...provide regarding compatibility, picture quality, filtering, smoothness, per file refresh matching/switching, library organization, future proofing...

    The only real difference is price. You pay serious money for stuff thats actually not relevant. Im playing blu ray quality 50gb movies with DTS HD sound in 1080p. You cant get any better than that!. Upscaling is a joke. you cant polish a turd. Its still crap quality video and its always going to look crap. You dont need a PC to work that out. Also upscaling is as good as it gets on a panasonic TV. Your PC might have good software but it wont beat the dedicated hardware built into a TV. Its a bit stupid to build a PC to watch standard Def. its like a 4k gaming PC to play diablo 2.

    Quite honestly my Macbook Pro would be more capable and powerful than any of your HTPC's and i can take the Mac out the house when i need to. Dedicated HTPC really is just a hobby and excuse to build a PC.

    Yes, you can. Chroma upsampling, per source refresh matching, playback-refresh perfect sync... LOL on the TV hardware vs PC software.

    Tell the majority of the world how improving SD as much as possible is stupid.

    I don't get the Macbook joke. At least I hope it's a joke.

    I'll get back to PC gaming on my living room tv now. I guess Macbook and Panasonic can do that better too.

    Sorry you lost all credibility when you told me that you play games with a PC on your TV.

    This is 2013 and Standard def has no place in my home or even my PHONE!.

    You do realise that a Macbook Pro has a i7 CPU and a 650M GT GPU inside? You can also install Windows and basically you dont need a separate box to do the things you claim you need to do.

    How long do you think its going to be until there is wireless display tech? then your HTPC is doomed. Because people can just use their normal PC or Laptop to do basically what you spent all that money building a dedicated device for.
  • Touche - Wednesday, January 23, 2013 - link

    Thank you captain obvious, I would never have realized that things will be somewhat different once wireless display tech gets improved.

    You do realize that your Macbook essentially becomes a HTPC when you hook it up to the TV? The very same thing you're dissing, though more expensive and limited.

    Also, it is nice of you to selectively disregard advantages even your limited usage scenario would see, and concentrate on dissing anything not of use to you or not up to your "2013" standard (what a lousy teenage girl thing to say, btw).

    I hope you can grasp the idea that many people have usage scenarios you don't, and have a great need and benefit from HTPC.
  • Touche - Wednesday, January 23, 2013 - link

    Oh, and as for the Macbook, it needs Windows to be as useful and capable as HTPC, at which point you're better of with a much cheaper laptop. And even then, as many HTPCs are doing something 24/7, or while you're away etc., it makes no sense to use a laptop. Hence the joke.

    Yes, yes, YOU don't need anything that doesn't come with MacOS, and YOU don't use anything HTPC related, or use it more than X hours a week, and YOU don't...so it's all just useless and nobody should have it.

    First of all a HTPC is basically an underpowered limited use box sitting under your TV. This is the point. Just about every other device now does what a HTPC does without actually having to have a separate PC. A Laptop a home desktop a phone, tablet or smart TV will do 95% a dedicated HTPC will do 95% as good. They really are going to go the way of the dodo. Extinct
