Question / Help Optimized stream for my config

[thejack]

Hi mate, i have some problem when i stream, usually league of legends, video looks a bit pixled when move a lot or have teamfight scene.
how could i set up for have better stream and something like 80ping(i have ~100 statics and 150-200 in fight now).

my setup:
i7-3820 3.6-3.8ghz (can handle slower preset compression)
ati 5870
16gb ddr3 1600mhz kingstone ram
1920x1080

1Mb upload, reach 1.1Mb peaks.


usally stream with:
1280x720
quality: 7
maxbitrate: 770
buffer: 550
fps: 25
preset: slower
encoding profile: high
priority class: above normal
Use CFR: on

what could i do for a decent stream?

Well, have a better internet access ?! (with better upload speed).

 

[thejack]

no, its just one of better in my country... with this upload nothing to do?

Unfortunately you will not be able to stream at 720p@25 with that upstream connection, with any kind of reasonable quality.
Consider downscaling to a 480 or 360p stream (depending on network overhead used by the game); I'd say that 1500kbps would be the sweet spot for a 720p@30 stream... 1.5Mb/s devoted *only* for the video upstream, with more on top for the game. You have about half that available overall. It's going to pixellate like mad with that little bandwidth available.

Run a 6MB test at http://www.testmy.net/upload as speedtest is worthless for livestreaming. I doubt there will be a huge difference, given the low upstream you have now, but it's best to make certain.

If you are streaming to Twitch, enable CBR and set your keyframe interval to 2 first-off. You'll want to downscale to 480p, and likely use a bitrate and buffer of about 700kbps. If you are using AAC audio, make sure it is set no higher than 96kbps (as that's on top of the video bitrate).


Short version... you need to either upgrade your network connection package to something with (significantly) more upstream available, or switch ISPs outright.

just for see this is the quality:
http://www.twitch.tv/thejacktv/c/3092468
is enough decent but sometimes pixel a bit more and i have more lag! some change? :) slower preset maybe save me a bit?

 

[thejack]

i found some setting to have a decent quality and low ping, just a question:
does Scene Buffering time change something in bandwidth usage?

 

[Boildown]

Each time you tweak your settings, post a new log file or we won't be able to say a whole lot. Make sure you stream more than 2 minutes each time, so we have a statistically significant sample to look at.

does Scene Buffering time change something in bandwidth usage?

Not sure, wouldn't mind finding out what that means as well.

1) I know you're bandwidth starved, but 48kb is a really low bitrate for audio. I would increase it a little for better quality if it doesn't sound ok.

2) Get rid of ALL of those custom x264 settings. Set your preset to Very Fast and get rid of all of that crap. I can't tell what's going on with your stream while those custom settings are there, because in no way am I going to take the time to decipher them.

3) Set your key interval to 2 seconds. Right now its at 10 seconds, because of a custom setting. Clear all custom settings and set it in OBS to 2. Turn on Constant Bit Rate and Constant Frame Rate. These are requirements for streaming to Twitch.

4) Try to set your audio devices to work at 44100Hz instead of 48000Hz, so OBS has to do less work. This is a setting in your audio devices, not OBS.

5) You haven't heeded our advice to lower your stream resolution. Increase the downscale, because you're not going to get a good stream with your low upload at 720p. Make your stream resolution something along the lines of 480p.

6) Once you've done all this, stream for at least two minutes and post a new log file from that stream.

1) I know you're bandwidth starved, but 48kb is a really low bitrate for audio. I would increase it a little for better quality if it doesn't sound ok.

2) Get rid of ALL of those custom x264 settings. Set your preset to Very Fast and get rid of all of that crap. I can't tell what's going on with your stream while those custom settings are there, because in no way am I going to take the time to decipher them.

3) Set your key interval to 2 seconds. Right now its at 10 seconds, because of a custom setting. Clear all custom settings and set it in OBS to 2. Turn on Constant Bit Rate and Constant Frame Rate. These are requirements for streaming to Twitch.

1) i tryed audio with this bitrate and its ok also with music!

2) tried with veryfast and use lot of bandwidth, i tried all preset and i can handle slow set, then less lag and better quality

3) i know twitch ask for key interval of 2 but is very much weight on the bandwidth, with 10key interval twitch refer me as acceptable, i know it cannot be see by mobile but until i have better connection i prefer it whatchable at better quality on desktop.
CFR - i will active it, but what is it?
CBR - twitch dont give me the advise to change to CBR with this setting also if im on VBR, and with this i can use less bandwidth

4) just did.

5) tried at low resolution and better quality and it give me less quality and more lag :S better find is 720p with this setting i have 50ping static!


tnx for all i think untill i will not have a better connection this is the better things i can do to offer a good quality with low ping!
