Schadenboner posted:Why is streaming such a technological challenge? I see (for example) "PCs for streamers" as an entirely separate category on Logical Increments and I'm confused. Is uploading of video output really that much more computationally intensive than mere display of that output locally? Because we gave billions of dollars to the major telcos and network owners in the late 90s to beef up their infrastructure, they pocketed it and did nothing, and we didn't throw people in loving jail for a thousand years over it. Now we have soda straw sized internet tubes and everybody's upload loving sucks so we have to burn a lot of electricity and use billions of transistors to optimize our video to fit in those tiny, tiny upload straws. We could all be on symmetrical gigabit pipes for $29 a month today if we would have strung up like four telco execs in '99

MrMoo posted:Real time video encoding with low latency is still a really expensive market with custom hardware ($10k+). The hope is with faster PCs you can avoid a lot of that and do it locally, however organisations like the MPAA are aghast at the thought. Usually the trade off is higher latency, like 30s used to be acceptable for streaming. er what it doesn't take $10k in hardware to encode video realtime with low latency. every smartphone today has a deece low latency encoder built in. so does every intel cpu which has an integrated gpu. so does every amd/nvidia gpu. encoders are everywhere and they're cheap 30s+ latency in streaming isn't a hardware limitation, it's an optional delay buffer which streamers can enable or disable

one of the reasons you hear "people used to put up with a streaming delay" is because twitch used to have a pretty significant and unpredictable one. but now, some of the newer streaming services have hardly any delay, and twitch's has gotten a lot better

yeah. brand new channels have Low Latency Mode ticked by default (i created a 2nd account last week for a test/dry run stream cause im bout to get back on the air and want to polish things up without notifying followers i'm live) which indicates to me that it's basically out of beta and turning it off is now like a debug mode or w/e

i know apple wants to keep it an all-on-the-phone experience but if they exposed HDMI or NDI out the lightning port, i'd probably buy one of those fuckin quad-digit iphones 12 pro and just get a nice tripod mount for it.

I'm not saying it is needed, I'm saying it is there, even B&H have a lot of random expensive encoders from $2-20k. Also see special snowflake requirements like the BBC with their Dirac codec. The expensive device mentioned is specifically the piece of junk encoding my 720p Dow Jones Index graph and sending it to CBS and other stations from the NYSE floor. 30s used to be the GOP buffer on streaming garbage like RealVideo, but is definitely not uncommon with 720p era encoding hardware. 5-7s today is common for average latency, i.e. the 6s GOP of 180 max frames that even Amazon media encoding services support. Low latency from Twitch is 1-2s, but if you just run regular webRTC encoding you can get single frame latency with no problems (I run video walls like this).

Lutha Mahtin posted:one of the reasons you hear "people used to put up with a streaming delay" is because twitch used to have a pretty significant and unpredictable one. but now, some of the newer streaming services have hardly any delay, and twitch's has gotten a lot better to expand on this, early on (back when justin.tv was either on its way out or already dead), twitch used rtsp and flash to transfer video, giving delays of about 3~8 seconds on average. as flash continued to get constantly poo poo on by the internet, twitch migrated to using hls. with hls came a huge increase in delay: upwards of 30 seconds. it was catastrophic when a lot of the fun of streaming is interacting with the person doing it. eventually twitch tweaked and hosed with settings and encoding details and got it down to about 10~15 seconds of delay. further changes and tweaks have gotten delay lower, often to about 2 seconds. unfortunately this also came with a lot of other changes; keyframe intervals are now set to 2 and bitrate is generally supposed to be set to a constant value. this means you lose out on a lot of encoding benefits with vbr, so either you waste a ton of bandwidth on scenes that aren't changing much or your video turns into mud because you can't burst above 2000kbps when a bunch of action happens. one of the old streaming alternative sites, hitbox, had low delay (in the age of 30s twitch) as their "big things". mixer also got delays down to a second or two, when twitch was around the 10s area. twitch has actually been historically terrible about stream delay but at least it's better, even if the rest of their site/product is dogshit.

relevant to that last bit our isp has been so consistently awful i wrote something that pinged our home connection from a server and graphed it out black = 0ms, bright green = 100ms, red = lost packet (each pixel is one second, one row per 5 minutes)  truly quality deserving of one hundred and thirty united states dollars. thanks, cox.

would you be willing to share that code because i need to prove to comcast that they hosed something up about three months ago and i went from Literally never touching my cable modem forever to needing to reboot it twice a day. my internet goes down EVERY MORNING at 10am. guess when my first meetings are.

i started tracking the cable modem's signals too, since that was a problem we had this mostly just helped diagnosing the issue where our cable modem was being driven to > 58.1dBmV power, which is just slightly out of spec. funnily enough when i first started doing this logging into the modem was done by plain-text query string parameters.
