Description

My Streamlink Twitch GUI streams have started to lag out of nowhere and I don't know why, I currently have these settings (that I used from the last 2-3 months) it was working fine but today the lag continues to happen (I would turn off low latency mode, but I kind of don't want the stream chat to be behind as well). Also tried switching different players from MPC to VLC and restarting my internet router also didn't help

My Streamlink Twitch GUI streams have started to lag out of nowhere

Streamlink Twitch GUI is not responsible for any streaming content. It is just a graphical user interface that acts as a launcher for Streamlink. If you're having issues with Streamlink, then this is not the right place to ask, as the issue template should have already told you.

Also, what do you mean with "lag"? Is it a network/connection related problem? Is it a video decoding/rendering related issue? Is it a player configuration issue?

Since you've already posted a debug log from Streamlink, you should check its log output when watching a stream, perferrably with the --loglevel=trace parameter, which will add timestamps to each log line. If you're having network issues, then this could potentially give you hints about your problem. Other than that, you should take a look at Streamlink's docs for all the available parameters that let you tweak the stream transport values (make sure that you are using the latest Streamlink development version, as there have been some changes since the last release, which is 2.3.0):
https://streamlink.github.io/latest/cli.html#stream-transport-options

Video decoding/rendering issues or player configuration issues can be debugged via Streamlink's --verbose-player argument if the player writes anything useful to stdout/stderr. If not, then you'll have to figure it out on your own and maybe take a look at your player's documentation.

The Streamlink Twitch GUI settings which you've posted should not cause any issues if your connection is fast and stable enough. The HLS live edge value is 3, which is the default, and low latency streaming will set it to 2 if enabled. You haven't set any additional player parameters, so there's nothing that could cause problems here.

However, if you're having network issues, then you'll need to disable low latency streaming and increase the live edge value by a bit. This will only work if you connection is fast enough to recover from download speed drops though. If it's not fast enough, then you'll have to choose a lower stream quality with a lower bitrate.

turn up your live edge u can prob put it back later also try using pot players that fixed 4 me
