Html5 Powerpc

Posted on by



Further, HTML5 video is supported on some older hardware and operating systems that Flash no longer supports – PowerPC in particular. That said, HTML5 video isn’t a single thing. There are three different types of video encoding supported by HTML5: H.264/MP4, promoted by Apple.

  1. HTML5 Video Performance on PowerPC Macs Daniel Knight - 2015.02.01 In my previous article, I looked at HTML5 video support in browsers compatible with Mac OS X 10.4 Tiger and 10.5 Leopard on PowerPC Macs. Today we’re looking at video performance on YouTube, which recently made HTML5.

In my previous article, I looked at HTML5 video support in browsers compatible with Mac OS X 10.4 Tiger and 10.5 Leopard on PowerPC Macs. Today we’re looking at video performance on YouTube, which recently made HTML5 video its default.

I’m using Galaxy Note 4 4K Test Video – How Good Is It? as my test video on a dual 2.3 GHz Power Mac G5 with 4 GB RAM and a 12 Mbps U-verse internet connection. Testing was conducted with OS X 10.4 Tiger and 10.5 Leopard.

This video was filmed in 4K resolution on the Galaxy Note 4 and uploaded directly to YouTube with no editing in between. It is available in 144p, 240p, 360p, 480p, 720p, 1080p, 1440p, and 2160p formats. This video runs 1:33. I’m testing at 360p, YouTube’s default, and 480p, which is DVD quality, when available.

You can send your browser to https://www.youtube.com/html5 to tell YouTube to serve you HTML5 video by default.

YouTube sends 360p video at an average of 735 kbps, 480p at 1237 kbps, so my 12,000 kbps service should not be a factor.

The video has 2,799 frames. Numbers are reported “stats for nerds”, which not all browsers support – and some support differently than others.

OS X 10.4.11 Tiger Results

Safari 4.1.3: No longer works with YouTube.

TenFourFox 31.4.0

  • 360p: 281 painted, 2518 dropped (90.0%), 3.0 avg fps
  • 480p: n/a

Opera 10.6: Unwatchable

Recommendation: Don’t bother trying to watch YouTube videos on a PowerPC Mac running Tiger. Our best result still dropped 90% of frames, for an average frame rate of 3 frames per second (fps) – and that’s on a high-end Power Mac G5 with two 2.3 GHz CPUs.

OS X 10.5.8 Leopard Results

Safari 5.06, MP4

  • 360p: up to 33 fps, 200 frames dropped (7.1%), average 27.9 fps
  • 480p: up to 20 fps, 1171 frames dropped (41.8%), average 17.5 fps

WebKit

  • 360p: up to 33 fps, 163 dropped (5.8%), average 28.3 fps
  • 480p: up to 20 fps, 1428 dropped (51%), average 14.7 fps

TenFourFox 31.40

  • 360p: 2172 painted, 627 dropped (22.4%), average 23.4 fps
  • 480p: n/a

Aurora 20a2, MP4

  • 360p: 2719 painted, 80 dropped (2.9%), average 29.2 fps
  • 480p: n/a
  • 360p: up to 33 fps, 180 dropped (6.4%), average 28.2 fps
  • 480p: up to 20 fps, 1066 dropped (38.1%), average 18.6 fps

Roccat: n/a. Stats for Nerds not available.articles

Opera 10.6: n/a. Opera does not let me click on anything while running a YouTube video. No pause. No setting quality. Nothing.

Camino will not display an HTML5 version of this video. It only gives me the option of using Flash.

Recommendation: Yesterday we recommended Aurora because of its support for all three HTML5 protocols, and with 360p video, it has the least dropped frames and highest average frame rate among tested browsers.

None of the 480p results averaged even 20 fps, so unless you have an even more powerful dual- or quad-core Power Mac G5, don’t bother with 480p resolution. 20 fps is a jumpy as those old Super 8 movies from the 1960s and 1970s. 30 fps is what you’re used to on TV, and anything below 24 fps is sub-par.

OS X 10.6.8 Snow Leopard

Just for comparison, I ran some tests with my an old, low-end Intel Mac, a 2.0 GHz Core 2 Duo Mid 2007 Mac mini with 3 GB RAM running OS X 10.6 Snow Leopard. Keep in mind that this machine has integrated Intel GMA 950 graphics, generally looked down on by comparison with dedicated graphics chips.

Like the Power Mac G5, the Mini is attached to a 1600 x 1200 pixel DVI monitor.

Because of the results I was seeing, I also tested some browsers at 720p, which has a 2346 avg kbps and fared surprisingly well on such low-end hardware.

Safari 5.1.10 will not report frame rate or let me choose resolution.

Firefox

Html5 Powerbi

  • 360p: 32 fps maximum, 85 dropped (3.0%), 29.2 avg fps
  • 480p: 32 fps maximum, 122 dropped (4.4%), 28.8 avg fps
  • 720p: 31 fps max, 287 dropped (10.3%), 27.0 avg fps

Google Chrome: webM

  • 360p: 2 dropped (0.7%), 30.1 avg fps
  • 480p: 3 dropped (1.1%), 30.1 avg fps
  • 720p: 306 dropped (10.9%), 26.8 avg fps

Stainless

  • 360p: 32 fps max, 1 dropped (0.04%), 30.1 avg fps
  • 480p: 31 fps max, 13 dropped (0.46%), 30.0 avg fps
  • 720p: 31 fps max, 32 dropped (1.1%)29.8 avg fps

Opera 12.13: no report

Roccat: no report

Html Powerapps

These results are frankly amazing compared to the dual 2.3 GHz Power Mac G5 with its dedicated video card. Over seven years after it was introduced, this little old Mac mini can hit 30 frames per second at 360p and 480p, and barely miss that mark at 720p using the Stainless browser, which I would suggest you try for the best YouTube video results based on this group of tests.

In the question of PowerPC vs. Intel, when it comes to watching YouTube videos, even very early Intel Macs have it all over dual-processor G4 and G5 systems, although it’s possible the Power Mac G5 Quad could hold its own against this 2.0 GHz Core 2 Duo Mac mini.

Html5 Powerpoint Presentation

On Tuesday, January 27, 2015, YouTube announced that it had made HTML5 video its default instead of Adobe Flash, which is still be supported. What does this mean for Mac users?

HTML5 video doesn’t require additional software, which immediately sets it apart from Flash video. Further, HTML5 video is supported on some older hardware and operating systems that Flash no longer supports – PowerPC in particular.

That said, HTML5 video isn’t a single thing. There are three different types of video encoding supported by HTML5:

  • H.264/MP4, promoted by Apple and Google, integrated into QuickTime
  • patent-free Ogg Theora, promoted by Mozilla and Opera
  • royalty-free WebM, sponsored by Google

Some browsers support all three, some two, some only one, and some old browsers none at all.

Each of these video formats has its pros and cons, with H.264 generally considered the most efficient, but with the drawback that it is not patent- or royalty-free.

I have been testing HTML5 video support on a variety of browsers supported by Mac OS X 10.4 Tiger and 10.5 Leopard on PowerPC hardware. My test machines are a dual 1.25 GHz MDD Power Mac G4 and a dual 2.3 GHz Power Mac G5. The test page I’m using is http://www.quirksmode.org/html5/tests/video.html

Video performance will vary depending on the speed of your internet connection, processor speed, the number of CPUs in your Mac, and your video card.

OS X 10.4.11 Tiger Results

  • Safari is the Mac’s default browser, and version 4.1.3 is the last supported in Tiger. Only H.264/MP4 video is supported.
  • Opera 10.6.3 supports Theora, but does not display H.264 or WebM.
  • TenFourFox is our standard recommendation for Tiger users. It is a PowerPC specific port of Mozilla (a.k.a. Firefox) that is optimized for G3, G5, and two varieties of G4 CPUs. The current version is 31.4.0, and I used it with QuickTime Enabler v.120 installed, which lets TFF use QuickTime to display video. Theora works nicely, WebM works very poorly on the G5 but nicely on the G4, and H.264 does not work at all.

Our advice to Tiger users: Use Safari for H.264 and TenFourFox for Theora and WebM.

OS X 10.5.8 Leopard Results

  • Leopard runs a newer version of Safari, 5.0.6, which only supports H.264/MP4 video, not WebM or Theora. Video on the G5 is very smooth.
  • Opera 10.6.3 is the most recent version for Leopard as well as Tiger on PowerPC Macs. As with Tiger, only Theora displays video. Quality is good on the G5 and not bad on the G4.
  • TenFourFox provides WebM and Theora playback, but not H.264. Theora seems a bit smoother than WebM on the G5.
  • Aurora is a Leopard-specific build of TenFourFox that is currently at version 20.0a2. It supports H.264, WebM, and Theora video – all very nicely on my G5.
  • Stainless is intended to provide PowerPC Mac users a browser that works similarly to Google Chrome by running separate processes for improved speed and stability with a reduced memory footprint. It supports H.264/MP4, but not the other standards.
  • Roccat is a newer browser designed to work on both Macs (OS X 10.5 and later) and iDevices. It only supports H.264/MP4.
  • On a lark, I gave the ancient Camino browser a try. It only supports Theora. (It doesn’t support anything on Tiger.)

Our advice to Leopard users: Give Aurora a try, because it’s the only PPC Leopard browser to support all three protocols.

OS X 10.6 Snow Leopard Results

With the impending demise of Dropbox on Macs running Tiger and Leopard, a lot of PowerPC users are going to be looking at low-end Intel Macs, and Mac OS X 10.6 Snow Leopard is the hands-down choice. It’s very similar to Leopard in the way it works (none of this Lion-and-beyond nonsense of replacing Save As… with Duplicate, for instance), is the last version of OS X that can still run PowerPC software, and has a smaller footprint than more recent versions of OS X.

Snow Leopard is Intel-only and will give you access to lots of newer software written only for the Intel OS X platform. If you’re on Intel, there really is no reason to stick with Tiger or Leopard; Snow Leopard is the cat’s meow.

I have a 2.0 GHz Core 2 Duo Mid 2007 Mac mini with 3 GB RAM and OS X 10.6.8 Snow Leopard installed, which is my primary production machine alongside a 2.0 GHz Late 2008 Aluminum MacBook with OS X 10.9 Mavericks that I use when in the field. The Core 2 Duo Mini was fairly low-end when it was introduced over seven years ago and has become more so over time.

  • Safari 5.1.10 is the newest version of Apple’s browser supported by Snow Leopard. It’s H.264 support is very good, and there is still no support for Theora or WebM video.
  • Opera 12.13 supports Theora nicely, WebM decently, and H.264 not at all.
  • Firefox 35.0.1 supports all three standards.
  • Stainless on Intel/Snow Leopard takes a step forward, supporting both H.264 and WebM, but not Theora.
  • Like Firefox, Google Chrome supports H.264, WebM, and Theora.
  • Roccat on Snow Leopard supports both H.264 and WebM, but not Theora.

Our advice to Snow Leopard users: Google Chrome and Firefox both support all three HTML5 video protocols. Give each a try to see which you prefer.
