H.264 Getting Dropped from Chrome

Terrible illustration of Chrome dropping H.264.If you pay any attention to the plodding chaos that is the development of HTML5, then you’ve probably seen the discussions around the video element and how best to encode videos. Over a year and half ago Ian Hickson gutted the video and audio portions of the HTML5 specification to remove all references to codecs, disconnecting the two competing standards, H.264 and Ogg Theora, from the next HTML standard. He did this in an email announcement to the WHATWG list, explaining the issues with licensing and browser support for both options.

At the time Safari refused to implement support for Ogg Theora, Opera and Mozilla refused to support H.264, Internet Explorer was silent, and only Google Chrome implemented both (though Google said it could not provide the H.264 codec license to Chromium third-party distributors).

A year and half later and Google has dropped support for H.264 from Chrome as of two days ago. While Google has hung its argument on the hook of license restrictions, it’s probable that Google is really just pushing its own WebM format.

The licensing argument is simple — the compression parts of H.264 are patented by MPEG-LA. While MPEG-LA has opened up the H.264 license for the web (after originally saying it wouldn’t collect royalties until 2016), it’s conceivable that move was intended to get the web hooked on it. And then it’s fair to assume the patent trolling might begin (history indicates the odds are good).

This announcement and the logic behind it has started off a mini-firestorm among developers on the leading edge of HTML5.

Ars Technica wrote up a pretty scathing review of Google’s move in the article Google’s dropping H.264 from Chrome a step backward for openness, suggesting Google’s real issue is about control over its own WebM format. The article goes into more detail about Google acquisition of the company responsible for developing what is now WebM and compares and contrasts the licenses of these and other standards.

Haavard Moen, who works for Opera, takes some time to disassemble the argument made by Ars Technica in his post Is the removal of H.264 from Chrome a step backward for openness? He breaks it up into 11 points, corrects or contextualizes them, and then suggests that the bulk of the points aren’t even relevant to the discussion at hand.

The chart below (and its comments) were unabashedly stolen and marked up from a graphic by Bruce Lawson (of Opera Software fame). He uses it to outline which browsers support which codec. I have added a column to list Ogg Theora.

Browser Ogg Theora Native webM Support H.264 Support Member of MPEG-LA H.264 Licensing Pool
Opera Yes Yes No No
Firefox Yes Yes No No
Chrome Yes Yes No No
Internet Explorer 9 No No Yes Yes
Safari No No Yes Yes

The two browsers that only support h264 video are Internet Explorer 9 and Apple Safari, the vendors of which have a financial stake in the codec:

The column in the chart asking about the MPEG-LA licensing pool is intended to show that the only browsers still supporting H.264 are those with a financial stake. Bruce updated his post with a link from a site visitor that claims that Microsoft gets far less from its financial commitment to H.264 than it pays in.

An argument that keeps popping up is that Google should drop support for Flash, given that it is not an open standard. I have dismissed this immediately on the argument that Flash has been here for a very long time, and it’s not practical to drop support for a technology that is already driving millions of sites, at least not without the myopic world view that Apple lugs around.

That argument, however, made it into the post from John Gruber’s blog, Daring Fireball, titled Simple Questions for Google Regarding Chrome’s Dropping of H.264. Remy Sharp was quick to respond on his own blog with My take on Google dropping H.264.

While Flash is only a part of that debate, it’s further insight into the arguments we’re hear from both sides. Some of the arguments will lean on a perceived double standard, as we see with the Flash example; some will lean on license debate, as we see with the constant references to MPEG-LA versus WebM and its background; some will lean on the quality of the video, which I intentionally left out of this post; and some will lean on who wants to be the next big monopoly for the burgeoning growth of video on the web.

For the average developer, it might be best to wait until the dust settles. You’ll still be making decisions based on browser support in the end anyway.

These links came rolling out this past weekend (January 14-16) and offer more arguments for and against H.264 and Google’s decision.

This will further push the popularity of services that will transcode your video files into every required format.

I still wonder how many of the developers who are up-in-arms actually develop projects in which video encoding / embedding is integral.

Andrex, thanks for the comment. I tried to keep my opinion out of it, but I just couldn't seem to muster the will to keep it out of the entire thing.

Levi, my guess is the number of developers who will be affected by this on a day-to-day basis is probably relatively small right now. In the end, a typical end user will probably never even know this dust-up even happened.

Great right up about the current state of things. Probably the only article I've read so far that isn't just an opinion piece.
