Back in 2010, champions of a free web were ecstatic over Google's plan to seed the internet with a patent-free video. VP8 was going to crush the patent-heavy H.264, now celebrating its 10th birthday. Or so we were told.
In May of 2010, Google open-sourced VP8, the video compression codec component to the audio-visual WebM format, which it had bought and developed earlier that year, and threw open the WebM Project to all comers.
Mozilla and Opera – who’d kept H.264 out of their browsers - were very much onboard, saying their browsers would play VP8 while AMD, ARM, NVIDIA, and Qualcomm joined the WebM Project working with others to build and patch code delivering hardware acceleration for the codec. Journalists were euphoric, producing articles like this: Google opens VP8 codec, aims to nuke H.264 with WebM.
But three years later, the party’s over – and it's Google and VP8 that were nuked. Mozilla – maker of the web’s third biggest browser – has swallowed H.264 in Firefox and Mountain View in March signed up to a licence for technologies in H.264.
Wait, YouTube's owner couldn't make it work?
On paper Google could – and should – have succeeded. It owns YouTube, a video service with so may users that Google reckons that, averaged out, every single person on the planet has watched 140 video views. It therefore had a critical mass of web video. Android runs most smartphones on the planet, meaning Google has the means to deliver royalty-free WebM video.
Google is also a $50bn trans-national machine run so smoothly that its tax affairs seemingly operate on a level beyond the grasp of ordinary governments. The company has its foot on the nexus of our web and our culture.
What thwarted Google was MPEG LA, a group that’s likely little known by the average square-eyed netizen. MPEG LA administers more than 5,500 licensees spanning families and generations of media patents. The group was created by a cluster of highly motivated technology companies - all MPEG-2 patent-holders - in 1997 to outsource the charging and enforcing of their patents.
Most ordinary punters won’t have heard of H.264 but they’ll have certainly experienced it. H.264 is a block-oriented motion compression technology used to play video offline and online. It's used on services from YouTube to Apple’s iTunes store - anything played by Adobe’s Flash Player uses H.264 - so that means most film, TV, porn and videos of cats playing the piano on the web. It’s the video compression technology used in Blu-ray players, too. H.264 was built using patented technology from Microsoft, Apple, the Fraunhofer Institute and others.
H.264 has taken over the web quickly: drafted in May 2003 there are today 1,600 licensees versus 2,000 for MPEG-2, which dates back to 1996.
Frank Sinton, chief executive of video indexing and search site MeFeedia, tells us succinctly that WebM has been, er, crushed. “H.264 has kind of won,” Sinton says.
MeFeedia in 2011 surveyed the millions of video feeds it indexes and serves and found H.264 played 80 per cent of HTML5 video, while WebM accounts for 2 per cent. MeFeedia didn’t bother researching the subject again. “That’s the reason we haven’t updated the numbers [since 2011] - the [H.264] codec [covers] so many browsers and devices.”
It was MPEG LA that helped ensure H.264's continued dominance and that started the grenade rolling under Google's feet, with an action that meant Google's VP8 web takeover was in trouble from the very start.
Google grabs On2 the next thing
In May 2010, MPEG LA’s chief executive Larry Horn said his group was looking into forming a patent pool against VP8 - this was after Google had bought On2 Technologies whose technologies became VP8.
MPEG LA patent pools collectively represent companies who believe their patents are being used in various technologies. An H.264 pool would have been used by MPEG LA to enforce its group members' patents. By February the following year, it had called on patent-holders to submit evidence of patents they believed were used in Google’s codec.
The pressure seemed to pay off and - as is so often the case in the world of patents and alleged infringements - it was the behind-the-scenes maneouvring ahead of any court action that paid, and saw Google sign a licensing deal.
Under the agreement, Google agreed to license “techniques that may be essential” to VP8 while MPEG LA agreed to call off the dogs, saying it’ll discontinue efforts to form the threatened VP8 patent pool.
Was it saber-rattling that pulled Google to heel?
MPEG LA’s Horn says: "No". “Patent pools get too much of the blame and too much of the credit,” he told The Reg on the anniversary of H.264.
“When I was asked: ‘Is VP8 patent-free?’ I said: ‘I doubt it because the tools that go into it are well known to be covered by patents.’ That got things fired up in the market. I didn’t do that as a threat - it might have been perceived that way. My point is if there’s a lot of IP rights in the market, then MPEG LA has an opportunity and a service to perform [by] forming a pool. The market may have taken that as a shot across the bow that MPEG LA is threatening us, but I would say it’s not true.”
