With numerous advantages, AV1 is now supported on about 60% of devices and all major web browsers. To accelerate its adoption – Beamr has introduced an easy, automated upgrade to the codec that is in the forefront of today’s video technology
Four years ago we explored the different video codecs, analyzing their strengths and weaknesses, and took a look at current and predicted market share. While it is gratifying to see that many of our predictions were pretty accurate, that is accompanied by some degree of disappointment: while AV1 strengths are well known in the industry, significant change in adoption of new codecs has yet to materialize.
The bottom line of the 2020 post was: “Only time will tell which will have the highest market share in 5 years’ time, but one easy assessment is that with AVC current market share estimated at around 70%, this one is not going to disappear anytime soon. AV1 is definitely gaining momentum, and with the giants backing we expect to see it used a fair bit in online streaming. “
Indeed we are living in a multi-codec reality, where AVC still accounts for, by far, the largest percentage of video content, but adoption of AV1 is starting to increase with large players such as Netflix and YouTube incorporating it into their workflows, and many others using it for specific high value use cases.
Thus, we are faced with a mixture of the still dominant AVC, HEVC (serving primarily UHD and HDR use cases), AV1 and some additional codecs such as VP9, VVC which are being used in quite small amounts.
The Untapped Potential of AV1
So while AV1 adoption is increasing, there is still significant untapped potential. One of the causes for slower than hoped rollout of AV1 is the obstacle present for adoption of any new standard – critical mass of decoding support in H/W on edge devices.
While for AVC and HEVC the coverage is very extensive, for AV1 that has only recently become the case, with support across an estimate of 60% of devices and all major web browsers, and complementing the efficient software decoding offered by Dav1d.
Another obstacle AV1 faces involves the practicalities of deployment. While there is extensive knowledge, within the industry and available online, of how best to configure AVC encoding, and what presets and encoding parameters work well for which use cases – there is no such equivalent knowledge for AV1. Thus, in order to deploy it, extensive research is needed by those who intend to use it.
Additionally, AV1 encoding is complicated, resulting in much higher processing power required to perform software encoding. In a world that is constantly trying to cut back costs, and use lower power solutions, this can pose a problem. Even when using software solutions at the fastest settings, the compute required is still significantly slower than AVC encoding at typical speeds. This is a strong motivator to upgrade to AV1 using H/W accelerated solutions (Learn more about Beamr solution to the challenge).
The upcoming codec possibilities are also a deterrent for some. With AV2 in the works, VVC finalized and gaining some traction, and various groups working on AI based encoding solutions, there will always be players waiting for ‘the next big thing’, rather than having to switch out codecs twice.
In a world where JPEG, a 30+ year old standard, is still used in over 70% of websites and is the most popular format on the web for photographic content, it is no surprise that adoption of new video codecs is taking time.
While a multi codec reality is probably going to stay with us, we can at least hope that when we revisit this topic in a blog a few years down the line, the balance between deployed codecs leans more towards the higher efficiency codecs, like AV1, to yield the best bitrate – quality options for the video world.
