It's been over a year since we covered jwplayer's State of HTML5 and now that the report has been updated, it's time for us to take another look. Chrome is still clearly in the lead in terms of HTML5 browsers with a full one-third share of the entire market. Now, that's not all browsers, because there are still many that are not HTML5 compliant. In fact, browsers supporting HTML5 are about 80% of all browsers out in the wild, according to the report. Let's take a closer look:
HTML5 Browser Market Share
Chrome is dominating the HTML5 supporting browser install base with that previously mentioned 33%, which more than doubles Firefox and IE9+ installs which are each at 14%. On the mobile front iOS and Android account for 8% each of total HTML5 browser installs. Amazing when you think about how popular those handy devices are and how many people have more than one.
Chrome is up 3%, Firefox down 5%, IE9+ down 2% from last year.
The more amazing thing is that 20% still don't have HTML5 support. Also, Opera dropped off the grid meaning that it has less than 1% market share. Windows Phone also has less than 1% and so too is not broken out. However, I'm not exactly sure how they arrived at these specific numbers because I could not replicate them at StatCounter, which is the cited source for the stats. There, Chrome ranges near 40% and IE 9 and 10 alone are over 15% in terms of worldwide.
HTML5 Browser Media Support
In terms of what media is supported, the only really interesting change is that Firefox now supports MP4, MP3 and AAC which it did not last year. Chrome and Firefox maintain their support for WebM and Vorbis as well.
Last year IE9 was ignoring the preload attribute but that's changed. The only platforms that don't support autoplay and preload are, logically, iOS and Android. Those two attributes along with player controls and the poster attribute are supported across the major browsers.
Fullscreen is another facet of the HTML5
Both the iPad and Android tablets support a fullscreen control, plus the (legacy) webkitEnterFullScreen() API. The iPhone and Android 2.x phones only play video in fullscreen, so a control is not needed, while Android 4+ phones play videos inline.
HTML5 Browser Text Track Support
Here is an area of major importance to us all as video SEO is forefront in our mind for HTML5
The next big thing seems to be images for seeking, chapters and searching. Right now on that Microsoft page above you can search their caption file to be taken to a specific time in the video. More interestingly in the future might be a film strip navigation where you can quickly read through the text and see a thumbnail for each chapter as defined by the publisher.
HTML5 Browser Support for Adaptive Steaming
Finally, jwplayer looks at adaptive streaming support across the HTML5 supporting browsers and it won't surprise you to know that it's a disaster in terms of support. The only browser with Media Source API support is Chrome. Safari, iOS and Android all have built-in HLS and that's all the support there is. The desktop majors don't support HLS and almost none support Media Source. It is quite new though and IE 11 is reportedly going to support it. The rest are also said to be working on it.
Of note is the warning that HLS is buggy on iOS and Android and so is a builder beware situation.
The Ultimate HTML5
It seems to me that if I'm going to be working with HTML5′s <video> tag, I'm looking at using Chrome. It supports the most features across the board. It's no wonder that it is a full third of all HTML5 browser installs currently based on their research. They are quick to incorporate new features when they become available and have helped shape the landscape somewhat. They folded on the WebM only thing unlike Firefox, in order to allow for wider implementation even though they had a hand in developing the other video format. Internet Explorer does sound like it will come close as they have announced support for several features that are vital for the success of HTML5 as a video player.
