color-space | Math & data behind color spaces and color conversions | Math library

I'm showing a notification in my app. I would like the small icon to be white in the status bar but another color (greenish) in the notification itself, as described in this question.

I'm using a 72x72, pure white, transparent, RGB-gamma-color-space PNG file as the icon:

This is how it appears in the status bar:

But it's still white in the notification itself (even though the app title gets the correct color):

This is the code I use to display the notification:

• I have Lego cubes forming 4x4 shape, and I'm trying to infer the status of a zone inside the image:

empty/full and the color whether if yellow or Blue.

• to simplify my work I have added red marker to define the border of the shape since the camera is shaking sometimes.
• Here is a clear image of the shape I'm trying to detect taken by my phone camera

( EDIT : Note that this image is not my input image, it is used just to demonstrate the required shape clearly ).

• The shape from the side camera that I'm supposed to use looks like this:

(EDIT : Now this is my input image)

• to focus my work on the working zone I have created a mask:

• what I have tried so far is to locate the red markers by color (simple threshold without HSV color-space) as following:

"Answer" of SDP offer is not sent to Web App(running on Windows/Mac/Linux) from Android/iOS application after updation of Chrome to latest v89 (released on 9 March 2021).

It is working fine on Chrome v88 and below.

Offer SDP:

Two Chrome browsers: Alice (A), Bob (B). Different networks, so i'm using Coturn server (my own).

The problem is that when A creates an offer - everything is ok, ice connection state goes to "connected", everything works fine. But if B creates offer - every peer receives the same Ice candidates, but ice connection state after 10 sec "checking" goes to "disconnected". It depends on in what network is B. Only on some networks there is such problem.

Here are the details:

Not working case:

B creates an offer. His descriptor is:

• I use NVENC (nvEncodeAPI) interface hardware encoding H264, and then RTMP to stream out, when using ffplay to pull the stream to watch, I found that the picture is obviously distorted: the green lines become sharper? the text color becomes lighter and blurred, it is not improved even if I increase the video bitrate to 3Mbps(720P). I also know that H264 encoding is lossy, and some information will be discarded.
• Then I try to adjust the NV_ENC_CONFIG_H264_VUI_PARAMETERS parameter: when set color-space to "pc, bt709", there are some minor improvements. Maybe the color-space setting has more potential for improvement? For NVENC encoding, is there a higher video clarity setting scheme? I don't know how much space for technical improvement is here? based on the code: https://github.com/obsproject/obs-studio/blob/master/plugins/obs-ffmpeg/obs-ffmpeg-nvenc.c

I am using Kurento media server in my webrtc Project. I am want to Increase Video Quality for my web call.

setmaxsend/recbandwith() is not working for value over 500 kb.

I want to change max bandwidth tell me how can do that.

what I need:

1. Is there any way to to that
2. Can i find actual variable which is used to define the bandwidth.
3. I want to Set Max Bandwidth 2000kb.

I am experimenting with a Sass @mixin that provides support for the display-p3 color-space and gracefully degrades back to sRGB when there is no support for display-p3. Currently, only Safari supports this spec.

I am trying to obtain all data inside dt/dd table structure on a website.

My current code looks like this:

I've been trying to learn WebRTC with React Native, so I've been working on this video call project. I thought I had it all figured out until this came up.

First of all, this is my React Native Code
