stream-m | A HTML5 compatible WebM live streaming server | Websocket library

I have a raw image that was taken with v4l2-ctl after the camera had been setup like:

This code creates two KStream instances separately, both are reading from the same topic:

I have a docker compose that containss a react app and other django container. They are in the same network so when I try to make curl request from the react container to one of the django services using the service name it works but in the web app it doesn't work and it said :

POST http://backend-account:8000/api/auth/login/ net::ERR_NAME_NOT_RESOLVED

this is my docker compose :

Thank you so much for taking your time and reply. Lets say I have to play live stream with the following requirements; How can I make a working Player for a browser?

Manifest URL = "https://live-stream-manifest.mpd"

Manifest URL require special headers which are;

HeaderName = "manName1" HeaderValue = "manValue1"

HeaderName = "manName2" HeaderValue = "manValue2"

Widevine License URL = "https://widevine-license.com"

Widevine License require special headers which are;

HeaderName = "licName1" HeaderValue = "licValue1"

HeaderName = "licName2" HeaderValue = "licValue2"

With the above info I made the following player but I don't know where to put the headers for manifest which are required when request is made.

I am getting an error with firebase functions. When I run the functions locally using emulators they work fine. But when I firebase deploy and on subsequent execution of a certain function, I get an error which suggests that the version of ffmpeg installed on the server I have deployed to is out of date

How do I update ffmpeg (or indeed any software) on the server? Maybe I SSH into it and update software? Maybe I should provide some config to define what software my code depends on prior to deployment? Please advise how an update can be done thanks

OPTIONAL READING:

My Node.js code uses execSync(myFfmpegCommand) which is why the dependency exists

Exercise 3.52,

SICP indicates cdr is opened up:

In section 3.5.4 , i saw this block:

I want to convert a nested map structure created by java streams + groupingBy into a list of POJOs, where each POJO represents one of the groups and also holds all the matching objects of that group.

I have the following code: I use project lombok for convenience here (@Builder, @Data). Please let me know if that is confusing.

My goal is to prevent two points from happening:

1. Having deeply nested maps and
2. As a result: Looping over these nested maps via keySets or entrySets to actually do stuff if the entries

Instead, I'd love a clean and flat list of POJOs that represent the grouping and conveniently hold the matching entries for each group.

Find the code on GitHub to run if locally, if you want.

Edit 1: I've updated the code again to remove the lastname and add another "Gerrit" object to have two objects with the same grouping. I hope this makes the intent clearer.

Edit 2: I have updated the code again to add a property on Person which is not part of the grouping.

I am looking for an output like this:

I have a stream of nodes and a stream of edges that represent consecutive updates of a graph and I want to build patterns composed of nodes and edges using multiple joins in series. Let's suppose I want to match a pattern like: (node1) --[edge1]--> (node2).
My idea is to join the stream of nodes with the stream of edges in order to compose a stream of sub-patterns of type (node1) --[edge1]-->. Then take the resulting stream and join it with the stream of nodes another time in order to compose the final pattern (node1) --[edge1]--> (node2). Filterings on the particular type of nodes and edges are not important.

So I have nodes, edges and patterns structured in Avro format:
