Dr. Video Games 0031 posted:Also, I'm not sure how much encoding latency factors into the wider latency picture for cloud gaming, but I wonder if this could help make that more responsive. I don't see cloud gaming moving beyond HEVC for a few years. It'll take a while for clients to support AV1, and unlike stored media on Youtube, there's no existing media to transcode from AV1 to HEVC/H264, just raw game output.

The previous generation card, the Alveo U30, doesnt have windows drivers and you can't buy it at retail. This isn't a consumer product. From the AT Article: quote:The target market for the card is, like its predecessor, the data center market. AMD’s principle clients are live streaming services and other interactive video services (think Twitch, cloud gaming, video conferencing, etc), all of whom need to encode large numbers of video streams in real-time in a server environment. So like AMD’s EPYC processors, this is very much a server part aimed at a select group of businesses. AMDs presentation made it pretty clear that it was targeted at:

Was able to put in an order for the 7800x3d at central computers but I guess their shipment was delayed a bit so it should arrive this weekend. Will be the first time I've had an AMD CPU since the very first computer I built with an Athlon XP 1700+ way back in 2003

I think we need to put into context some of the concepts of "bandwidth costs" being a matter more of bandwidth limits on the client side similar to why there's such a focus upon power efficiency on the hyperscaler side. The hyperscalers already hit the legal limits of power allowed in their various municipalities and so they generally can't scale horizontally by consuming more electricity even (think all land has been bought so all you can do is build more dense apartments). For consumers in the US mass market adoption of a lot of technologies relies upon the simply horrible cellular infrastructure combined with the lack of upward economic mobility of younger consumers, so to improve the experience for many of these users it's going to be easier to improve encoding standards rather than expect bandwidth to keep going up linearly for them like it did years ago.

BlankSystemDaemon posted:That's a loving hilarious daughterboard; I bet Intel were thinking "this is how we're gonna make big bugs from our Scalable Video Technology" SVT is software encoding, I think the idea here would be to turn the CPUs into iGPU video encode offload accelerators, literally using CPUs just for the GPU perf (and throwing a bunch of side cache at it for a dedicated scratch space). Or at least using client/laptop quad-cores is not gonna be that fast, probably within similar reach of a config you could build with normal server CPUs (albeit probably a more expensive server, but I doubt that would have been a cheap product either). It's somewhat interesting that a number of companies have made a run at the hardware video encoding market for a number of years. Rabb.it had custom servers with a bunch of jetson tk1s inside a 1U with some NUCs controlling them (arise, methenar). Intel made this video encode board. Google reportedly commissioned AMD to make RDNA1 HEVC really good for Stadia, because they had the same business need too. Now Xilinx/AMD have another take on it (without any attached GPU compute this time, to drop costs per stream). I guess it's a very common need to just encode some video quickly for whatever use-case, video-encode-as-a-service tailored to some segment. I kinda thought that had already been fairly democratized, it's not like it hasn't been a thing NVIDIA has addressed for a while. the Grid series were basically designed for these sorts of things (VDI, teleconferencing, etc) even 10 years ago, and more recently a t4 card is a very cheap buy-in for a hardware nvenc encoder with turing quality. And hell every phone SOC (raspberry pi etc) has come with video encode for a long time. It's interesting that apparently a quality-optimized encoder running modern codecs at the lowest possible cost ($1600 is fairly cheap for server given what it does) makes a relatively modern ASIC on probably a decent node (6nm? 5nm?) a viable proposition. I guess AMD see a big future in AV1 content delivery/encoding, and in all fairness it could result in tangible savings for companies like Google (your youtube upload never watched? now it's squished to av1 for space savings), although of course at a certain scale they can also commission whatever ASICs they want (custom 16nm or even 6nm isn't all that insane if you're a hyperscaler). I wonder what market penetration looks like for AV1 decode these days. Based on the slide Cygni linked, it sounds like maybe it's also grid compute stuff, video encoders for your PS Now and stadia and other streaming services. But again the question there is what you're attaching them to that doesn't already have an encoder - consoles do, dGPUs do, phones do, almost every PC does. Is your quality enough better to warrant the cost than just having the client's laptop do it (if they're cheap, then welp quality sucks, sucks to be you)? If it's just pure VDI, isn't having the dGPU portion of the card an advantage to accelerate the desktop? Twitch/onlyfans datacenter re-encoding, or youtube archival data compression - sure I guess, but how big is that market? It's a real cool product, I'd love to have one for turbonerd reasons, but it's a mildly perplexing product in terms of market fit, like who does this product fit that wouldn't just buy a bunch of quadro A4000s or T4s instead? twitch and teleconferencing I guess? I guess the answer may just be that this was developed before Xilinx was acquired and these are the pieces of the product they had in 2019 or 2020 or whatever.

AV1 is pretty cool and I'm a bit upset that the RTX 30 series doesn't have an AV1 encoder now that YouTube supports it fully for streaming and Twitch is rolling it out slowly iirc. It's great at all scales of real-time encoding from what I've seen of it and if I ended up streaming again I'd probably want to take advantage of it just for the quality improvements at any given bitrate target. It's also making some pretty big waves rollout wise -- Cisco's gone all in for it on Webex and it's done wonders for making screensharing more viable for people with poo poo connections and on mobile. One of my project managers lives in the boonies and until recently was on a connection that barely passed as ADSL and it was literally impossible for her to do screen shares and video at the same time. When the AV1 update rolled out screensharing bandwidth got cut down to like, a quarter of what it was previously and she could actually reliably share her screen and have her camera on at the same time in meetings.

Maybe by October or November, we'll have the FPGA report for 2022. EDIT: The Xilinx FPGA product dates back to 2018 at least.

From what I've seen AV1 software encoders are already really good, and Facebook reported that they're able to encode faster than x264 "faster" or x265 "ultrafast" speed settings while producing better looking output: https://engineering.fb.com/2023/02/21/video-engineering/av1-codec-facebook-instagram-reels/ Why does the AV1 have to be hardware? Why not just buy a CPU with more cores then games can use anyway and do encoding in software? Software encoders look significantly better than any of the hardware encoders if you can throw enough CPU at them. Software encoders also get better and better over time.

FWIW Youtube's AV1 and HEVC transcodes are poo poo unless you give them 4k+ to start. My 4k/2880p HEVC uploads look great, but anything I've tried in 1080 has come out looking less than stellar (even if it's 100MB/s). If you're just using Adrenaline's record & stream poo poo, using AVC (h264) will give you the best results still.
