Dear Sirs,

I am from Karachi, Pakistan and I am unable to stream properly on twitch as i get high latency on it so please launch Middle east /Pakistani servers for twitch. Due to the unavailability of these servers. I am either directed to Mumbai, Singapore or EU servers on which i get 140ms plus ping if there will be middle east servers. I will be getting around 10 to 40ms ping which would be perfectly fine for low latency streams.

As Pakistan is the 6th most populated country in the world and the increase in gamers/streamers in Pakistan is rapid so it is necessary for you guys to take these feedback seriously if you dont take action against this now then Pakistanis will be forced to stream on other platforms like Mixer, YouTube etc and grow their community there.

Thanks

Hello. We used to have many different servers in the region that for some reason got deprecated one day with no announcement or reason as to why it happened. And now we only got servers available in Brasil and many of us can't stream to them because of bad routing (Chile or Peru work a lot better, for example) so if at least a new server could be added for Chile in the region it would allow many of us to have a stable connection and finally stream normally as we should be able to. Please, we really need some of these servers back.

Hi Twitch!

I'm certain y'all know about this problem already, but I wanted to tack on some details in case it might help along with solutioning.

Since COVID-19, DJs all flocked to streaming, many of them on Twitch. Low Latency Mode is creating jarring pitch bends that most DJs nor their listeners know about. Savvy listeners think the DJ is just doing a bad job. Even non-savvy listeners can tell something's not right. But DJ's have no idea that this is happening; even if they enable past broadcasts, their VOD won't have this problem. When listeners point this problem out, DJs often have no idea what the listeners are talking about.

I'm sure you know the cause but I'll elaborate for everyone's sake.

Low Latency Mode, if I understand correctly, tries to catch up viewers who've fallen behind (e.g. due to a temporary blip in their Internet), to the latest point in the stream, by ever-so-slightly increasing the speed of playback. This doesn't matter too much for speech: people notice a change, but it doesn't affect their understanding. It also doesn't matter too much for video game music: people notice a change, but it's the ambience / energy that matters, not so much the pitch.

When it comes to music performance though, it can be a big deal, particularly for DJ streams, which have exploded since the virus outbreak. DJs aim to provide a smooth, uninterrupted feel over extended periods of time. But low latency mode disrupts the vibe and even makes people stop dancing. Look, I know how annoying musicians can be, but I'm not exaggerating: I've been in Zoom dance parties or hanging with a few friends where even non-musical ones stop dancing and feel something "off" has happened.

Even non-trained ears can hear pitch differences with surprising accuracy. I can make a recommendation that would make the pitch difference much more tolerable.

By my ears, the pitch shift I hear is around around 50 cents (i.e. about a quarter tone) for music playing at 123 bpm. I suspect the catch-up speed factor actually varies, but I don't know your algorithm. Anyway, centered around 123 bpm (since pitch is logarithmic), each 1 bpm up shifts pitch ~14 cents. So for me to hearing 50 cents, your algo must be pushing 123 bpm to 126-127 bpm. In other words, low latency mode is increasing speed by as much as 3%. It's understandable that 3% sounded totally acceptable from a general playback product perspective that wasn't geared toward DJs. But, this probably has to be reviewed if you want to continue supporting DJ streams. (Which, if you don't care, that's fair :-)

So what if we take a practical approach. "Instrument Timbres and Pitch Estimation in Polyphonic Music," Loeffler, B. D. (2006) says that the smallest pitch difference human ears can detect is 6 cents. But it's not like you have to fool professional musicians. I'm sure even lowering the shift from 50 to 15 cents will make a world of difference. To do so, you have to cap the speed increases to +1% at most.

So:

1. Is it viable to cap low latency mode's speed increases at +1%?


2. If no, is it viable to do so just for Music & Performance Arts channels?


3. If no, is it viable to make it an opt-in setting for the broadcaster?


4. Or maybe some compromise where, when the user's not too far behind it caps, but when they are, it does whatever it does today?

I trust y'all to make the right call. I also trust that you may have bigger fish to fry.

Appreciate all your work and wishing the best to everyone there.

The video player will buffer causing a long "Latency To Broadcaster" when the streamer has intermittent connectivity issues. For desktop streamers this is usually not a problem. This is a nuisance for viewers watching IRL streamers who are streaming on less reliable mobile connections. Who wants to watch a stream where the "Latency To Broadcaster" is over 30s? or even 10s?

I have to open the "Video Stats" menu with every stream I watch to keep an eye on the "Latency To Broadcaster" to make sure I'm not too far behind the live stream. Nothing wrong with my internet connection. Problem is on the streamer side because they are on mobile. Twitch has made the viewing experience worse by making the "Video Stats" box even bigger that's not even transparent with the latest site updates. I understand some viewers will always have high latency issues due to poor internet service. But for viewers that want to say close to the live stream we should have that option.

1. Give viewers a live button similar to youtube to skip closer to the live stream... not sure why twitch hasn't copied this basic feature yet




2. Allow viewers to customize contents of the "Video Stats" box... so viewers can just display "Latency To Broadcaster"




3. Have an option in the video player where viewers can set the maximum "Latency To Broadcaster"... if the latency falls over 10s the player will automatically skip to the live stream... Ideally I never like to be over 5s from the live stream for streamers that have enabled "Low Latency"
