Google I didn't plan on this, but there's really nothing I can do. Unless you want me to write about the upcoming ten billionth download from the iOS App Store, you'll have to settle for this. On the Chromium blog, Google has clarified its decision to drop H.264 support from the Chrome web browser, and in it, Google basically repeats the things that those concerned about the future of video on the web have been saying for a long time now: H.264 on the web kills innovation.

"Whether one is using an Android device or an iPhone, I would assert that the best available video experience is due to the availability of hardware-accelerated H.264. Unless anyone can make a compelling argument for WebM as a replacement now.....not in some imaginary future...well....Hmmm..


Have you actually tried each one, or are you just guessing?

iPhones and Android phones have smallish screen resolutions. While WebM is very slow to encode, it is faster at decoding than H.264 is. Although a device such as an iPhone really needs hardware acceleration to decode H.264 even at iPhone screen resolutions, the same is not necessarily true of WebM.

WebM decoding first became available in Android around December last year with the release of Android 2.3 Gingerbread. Even then, Google warned that Gingerbread doesn't include the Aylesbury improvements.

http://gigaom.com/video/gingerbread-android-webm-vp8/
The first version of Android will ship with libvpx 0.9.2, which is a slightly outdated version of WebM. Support for the newest WebM release 0.9.5, code-named Aylesbury, will be pushed out with a maintenance release, according to Google’s WebM product manager John Luther. Users will be able to access every WebM video stream or file with the WebM release included in Gingerbread, but the coming update should help with the format’s playback performance and memory footprint, amongst other things.


Aylesbury was released in October last year:

Aylesbury offers a 20-40% (average 28%) improvement in decoder speed.

So, in order to compare what is available right now, you would have to compare an iPhone side by side with an Android 2.3 (Gingerbread) phone with the WebM maintenance update installed which includes Aylesbury code.

Let me guess ... you didn't do that.

So you are just guessing.

I'm not 'guessing' that native H.264 video has been all-but-perfect on my iphones for years. I've spent time this week comparing WebM video in Firefox 4 with H.264......the former will need more than a 'maintenance update' to cut it for me....ymmv.

To be expected. Google did not say that the change was instant. Just that it would happen. So by the time the change happens Aylesbury and other improvements will be out there.

http://www.webmproject.org/hardware/ This is the thing most people keep on missing.

Start of this year we can expect hardware encoding of WebM. Hardware decoding H264 combind with hardware encoding to WebM process of conversion will be a lot faster. For a live stream where people don't need to go backwards along the transmitted file this could be good.

I would expect google to target change over for the end of 2011.

Google's Oulu, Finland division. Is an important thing to note when people say Google is a 1 trick pony. There is no reason why Google if they had wanted to could not have entered ARM chip making.

One cannot compare WebM video in Firefox 4 with H.264 ... Firefox 4 does not support H.264.

If you are talking about comparing HTML5/WebM with a Flash plugin you are not comapring the codecs but rather a whole number of layers.

Finally, Firefox 4 is for desktops, there is a separate Firefox released for devices (phones and tablets), it is called I believe Firefox mobile. This is important because of screen resolution ... screens on phones/mobiles have lower resolution that desktops, and the screen pixel count that one is displaying has a very significant impact on performance.

When you have actually compared H.264 on a phone/mobile with the latest WebM on the same hardware, then get back to me then with your observations about which is the better experience. Until you can compare apples with apples, you are indeed just guessing.

BTW, if you are really, really keen on making an absolutely fair comparison between H.264 on an iPhone versus WebM/Android available today on a mobile device that supports it, you need to get hold of a mobile device which has a Rockchip RK29xx and which runs Android 2.3.

I think the first WebM Rockchip to market might be the RK2918.
