{Hardware} and software program assist for the royalty-free AV1 video codec has been steadily constructing during the last couple years. {Hardware}-accelerated encoding and decoding is turning into commonplace in additional GPUs, telephone SoCs, and different {hardware}, whereas streaming video companies like YouTube and Netflix have begun serving AV1-encoded video to gadgets that assist it.
Open-source software program tasks are starting to observe swimsuit, too. The Open Broadcaster Software program (OBS) bundle has been increasing its AV1 capabilities in current releases, and now the Handbrake video transcoding app has added AV1 assist as nicely. Model 1.6.0, launched yesterday, has added assist for encoding AV1 video utilizing each CPU-based SVT-AV1 software program encoding in addition to by way of Intel’s AV1-capable QuickSync video encoder included in its Arc GPUs.
Nvidia and AMD’s newest RTX 4000- and RX 7000-series GPUs additionally embrace {hardware} encoding assist for AV1, however the software program wanted to make use of it hasn’t been constructed into Handbrake but.
AV1 is an open-source video codec developed by the Alliance for Open Media, a bunch that features heavy trade hitters like Google, Netflix, Amazon, Intel, and Microsoft. Just like the H.265/HEVC codec, AV1 permits far more environment friendly video compression than the previous H.264 codec, permitting for streaming of 4K and HDR video with out requiring an enormous improve in bandwidth relative to 1080p video. Not like HEVC, assist for the AV1 codec might be added to absolutely anything with out paying royalties.
HEVC’s important profit over AV1 as of this writing is that it enjoys a lot wider assist than AV1 throughout many generations of {hardware} from most main producers. Roku helps AV1 decoding in a few of its higher-end streaming gadgets, however allegedly pushed again towards Google when the corporate tried to power Roku to assist AV1 decoding throughout its whole lineup. Apple’s AV1 plans are additionally murky—the corporate is a member of the AOMedia group and a few rudimentary AV1 assist has appeared in its developer documentation lately, however hardware-accelerated AV1 decoding and encoding both is not supported or hasn’t been enabled in its most up-to-date Apple Silicon chips.
