Will there be a Hardware Acceleration for AV1 Soon?




AV1 has now become one of the domination

You may know or may not, almost all videos you can reach on the Youtube, are VP9 or AV1 encoded. VP9 is the codec Google developed to offer a better solution for online video storage & transmission. The AV1 was developed by the Advanced Open Media Alliance (AOM), led by Google, Amazon, has become the next-generation video codec for their Youtube platform.

A typical Youtube AV1 video
Fun fact: Videos uploaded after Jan, 2020, are all AV1 codec encoded (On Youtube).

In the predictable future, all videos with various videos on Youtube will be united & replaced by AV1 encoded videos, which explained the domination of AV1 codec. Also, Netflix announced their plan to use AV1 codec for all their video streaming service shortly, the expansion of AV1 application can be easily estimated.

The biggest issue that AV1 codec currently has.

1. Encoding Time Efficiency

Be at the dominant position does not mean AV1 video achieves all ways to its best. Some bottlenecks restrict the overall performance of this newly released video codec. One of the most critical issues is the time complexity for its encoding process.

The AV1 hardware support

Because all raw videos need to be encoded with a certain type of video codec in order to better transmission and distribution. AV1 codec is the one that has the best compression rate but takes an intolerable amount of time to compress the video. In our previous article, we have a deeper discussion to this: a video file size with AV1 encoded could be 50.3% smaller than it compressed by H.264 main profile, but take almost 100 times the time that spent on encode the video.

2. Not Currently Hardware Backed up

Fortunately, AOM engineers are working on the effectiveness of AV1 software/hardware encoding. With their best effort, the following chart shows the recent major improvement the AV1 have made:

A significant improvement with a sole software encoder

The test is based on the fact AV1 is temporarily no hardware encoder supported (in personal computer domain), as we can see a great prompt but still time complexity compare to x265, that would means that a full hardware support is necessary for this new codec.

The progression & participants of AV1 hardware encode

The Paticipants

One of the very possible reasons the AV1 video incapable to accomplish the fast encoding task is due to the absence of hardware supports. No hardware encoding support yet to be delivered until early 2020 results severely influenced the inclusive encoding performance of AV1.

Efficient hardware-based encoders are currently in development by groups like SocioNext. They made headlines when they revealed the first real-time encoder with AWS which they demonstrated at NAB 2019. Although this is obviously exciting news, there is a long distance between creating a demo and releasing a production-ready produce.

The AV1 hardware support
Allegro have released their most advanced harware that supports AV1 on July.

Also Allegro DVT, a leading provider of video semiconductor IP solutions, today announced the release of its AL-D21x family of video decoder IPs which adds support for the AV1 video format. This indicates that the electronic embedded AV1 hardware support is matured.

RTX 3000, with the best performance & support to AV1 video codec

September 1st, NVIDIA has released the specification of their newest NVIDIA RTX 3000 series GPU, excitingly announce that their new 3000 series will adapt the full AV1 hardware encoder/decoder for better AV1 video watching/streaming experience.

The planet’s biggest Internet companies have banded together to create AV1, a royalty-free, highly efficient video codec. This reduces the bandwidth required to stream high resolution video by up to 50% compared to H.264, and makes 4K and 8K high resolution streams feasible for consumers lacking the fastest Internet connections and unmetered contracts.

GeForce RTX 30 Series are the first discrete GPUs with AV1 decoders (as part of their new 5th generation NVIDIA Decoder), enabling users to take advantage of AV1 on desktops and in media centers.

 

The WinX VideoConverter Deluxe is your perfect friend

The AV1 hardware support
Digiarty's Video Converter Deluxe now support converting AV1 & AV1 hardware acceleration

As stated, AV1 codec isn’t yet mature & in lack of supportive hardware/software solution. Digiarty has long-term dedicate to multimedia softwares and our WinX Video Converter Deluxe is now supporting convert AV1 codec video. At the moment that less video software support AV1 related converting/ modifying, WinX Video Converter Deluxe is one no doubt a good choice. To promote the user experience, the Digiarty will focus on improve the AV1 support adequately to our customer.

What we can do expect in the future?

AV1 codec will surely become more popular in the future and is widely adopted by more online video resources. In the current stage, within tech giants joining and participating the development & deployment of usable AV1 hardware encoders, we can expect more applications of AV1 codec & videos will be seen. And, stated by tech media, the NVIDIA & Intel has joined this campaign, make the incoming entrenchment makes future of AV1 codec is considered promising.
