Hardware and software support for the royalty-free AV1 video codec has been steadily building over the last few years. Hardware-accelerated encoding and decoding is becoming standard in more GPUs, phone SoCs, and other hardware, and streaming video services like YouTube and Netflix support AV1-encoded video. We are starting to offer it to devices.
Open source software projects are starting to follow suit. The Open Broadcaster Software (OBS) package has expanded his AV1 capabilities in recent releases and now also adds his AV1 support to the HandBrake video transcoding app. Released yesterday, version 1.6.0 added support for encoding AV1 video using both CPU-based SVT-AV1 software encoding and Intel’s AV1-enabled QuickSync video encoder included in Arc GPUs.
The latest RTX 4000 and RX 7000 series GPUs from Nvidia and AMD also include hardware encoding support for AV1, but the software required to use it isn’t built into HandBrake yet.
AV1 is an open source video codec developed by the Alliance for Open Media. The Alliance for Open Media is a group that includes industry heavyweights such as Google, Netflix, Amazon, Intel and Microsoft. Similar to the H.265/HEVC codec, AV1 enables much more efficient video compression than the older H.264 codec, allowing streaming of 4K and HDR video without significantly increasing bandwidth compared to 1080p video. Make it possible. Unlike HEVC, AV1 codec support can be added to almost anything without paying royalties.
The main advantage of HEVC over AV1 at the time of this writing is that it enjoys much broader support than AV1 on many generations of hardware from most major manufacturers. Roku supports AV1 decoding on some of his high-end streaming devices, but is said to have backlashed with Google when Roku tried to force his entire lineup to support AV1 decoding. I’m here. Apple’s AV1 plans for him are also vague. The company is a member of his AOMedia group and recently basic his AV1 support appeared in its developer docs, but hardware accelerated decoding and encoding of his AV1 is not supported or not. , is not enabled in it. The latest Apple Silicon chips.
