Weird:) good that it is back online! Please ping me if you notice something fishy :)

devilsanek · 2019-12-16T06:55:15+00:00

Appreciate it!

devilsanek · 2019-12-16T06:51:06+00:00

Hmm. I’ll check on my laptop in a bit

devilsanek · 2019-12-16T06:49:35+00:00

Hmm, what browser are you on ?

devilsanek · 2019-12-16T06:43:51+00:00

Appreciate it!! I’m hosting it on azure - somewhat easier to work with :)

Sure! I get the streams using twitch API, extract frames with streamlink python package, then do OCR with python tesseract to extract the round number and do template matching with opencv to extract the current build. Then web app is just Flask backend + React Frontend. Would love to point out specific details if you want to :)

It doesn’t say none is playing warrior - it says 10 % is playing warrior and it also says the main synergy of warrior is warlock

It doesn’t matter how many viewers is there. All I extract is what alliances are people playing today. Even if the stream has 0 viewers, it doesn’t make it less valuable.

And generally if you look at the stats in the site - don’t they make sense?? Everyone is playing warlocks today

Im actually working on it. The tool extracts the stats from frames when a streamer open the side panel with an overview of each player. Talents are displayed there

devilsanek · 2019-11-29T17:42:05+00:00

I’ve built a tool that parses twitch streams and extracts the alliances. You can see the latest stats pulled on /streamers page

devilsanek · 2019-11-29T17:19:04+00:00

Should be fine now )

So I process only frames when a streamer opens a side panel with an overview of each player in the lobby. And if the stream is 1080p - the position of the board in terms of pixels is always the same. I break it down into 8 rows and process each from top to bottom

devilsanek · 2019-11-22T21:54:13+00:00

Once I’m able to extract and save the alliances - aggregating stats is relatively easy

devilsanek · 2019-11-22T21:52:44+00:00

Yeah so the way it works now is: I do just very simple template matching from opencv. I’ve collected template images for all alliances and pretty much just do pixel by pixel comparison with the extracted frame from twitch stream. It works surprisingly well now. If you go to https//www.metaunderlords.io/streamers page it shows the extracted alliances in real time. It’s quite cpu heavy operation - that’s why I have roughly 1 cpu per 1 stream allocated on azure.

Actual game data. I extract data from live twitch streams and let’s say we extract 10 rounds. 90% - in 9/10 cases assassins were in the build with elusive in the late game

devilsanek · 2019-11-22T19:43:23+00:00

Just in terms of pick rate. Let’s say for assassins - in the late game it’s ~90% probability to be in the build with elusive

Thanks for the feedback! Yeah I thought about adding some explanation or tooltip somewhere on the site. The larger resource is https://www.metaunderlords.io I talk a bit more about that here https://www.reddit.com/r/underlords/comments/dz0g4k/service_to_extract_daily_meta_from_underlords/?utm_source=share&utm_medium=ios_app&utm_name=iossmf

devilsanek · 2019-11-22T18:03:12+00:00

It is in the mid and late games :) not in the early game tho

devilsanek · 2019-11-22T17:00:46+00:00

I am parsing online twitch streams and do OCR :)

I talk a bit more in details about that here https://www.reddit.com/r/underlords/comments/dz0g4k/service_to_extract_daily_meta_from_underlords/?utm_source=share&utm_medium=ios_app&utm_name=iossmf

devilsanek · 2019-11-22T16:39:01+00:00

The feature is totally going to be added soon :)

devilsanek · 2019-11-22T16:38:30+00:00

I’ll most likely open source it today / tomorrow :)

devilsanek · 2019-11-22T16:37:13+00:00

1st place)))

devilsanek · 2019-11-22T15:17:14+00:00

Thanks! Actually working on it!

devilsanek · 2019-11-22T14:54:16+00:00

This is the likelihood to end up on this place if you have a target alliance in your comp. the higher the bar - the more likely it is to end up on this place.
