video-streaming | A simple video streaming service | Stream Processing library

I am experimenting with the code found in Miguel's tutorial on streaming jpg images with flask. part1 part2

I tried to add socketIO to the example. but I found that it leads to heavy lagging even if a monkey patch is used. I boiled down the problem to this short example seen below. If I start the socketio instance then I see in the terminal that the generator provides consecutive frames at a regular interval, but in the browser only about every second image shows up. If I use app.run(...) then everything works fine. Using socketio with async_mode="threading" also fixes the streaming.

What am I missing?

I need to stream my desktop using flask but I'm confused. I saw here - https://blog.miguelgrinberg.com/post/video-streaming-with-flask that I can "fool" flask to think I have a webcam and stream another images. I tried to get the desktop image using the gen(camera) method and made a few changes to the Camera class but I still get a blank screen and couldn't find a solution online. My code:

I have media server running on port 1935 .

and I have a subdomain: "streaming.foo.com"

I need to configure Nginx to access rtmp://streaming.foo.com

I tried the RTMP Nginx plugin with this blog :

https://www.nginx.com/blog/video-streaming-for-remote-learning-with-nginx/

and configured the /etc/nginx/nginx.conf file.

Assume a pipeline like the following:

totally new to this, so please don't judge too hard. Little uni project, trying to set up an RTMP NGINX server within a Ubuntu OS virtual machine on my mac.

Ubuntu OS --> 20.04 LTS

Mac OS --> 10.15.5

I'm following two guides... https://www.nginx.com/blog/video-streaming-for-remote-learning-with-nginx/ and https://www.servermania.com/kb/articles/nginx-rtmp. For both guides everything works fine until I try to make. I get the following error --> Prepending sudo does not help either.

Thanks in advance for any help!

I have followed along the documentation/tutorial on how to set up the config file for RTMP streaming from here: https://www.nginx.com/blog/video-streaming-for-remote-learning-with-nginx/ and it is pretty straight forward. However, I am not sure how I can have my backend built on Flask to redirect the stream to some HLS/DASH video player that is embedded in an HTML template that is sent in response to a client that requested for a specific HTTP endpoint. The tutorial shows how to view locally in a VLC media player but not how to embed it in an HTML file that gets sent to the client. How would I go about doing this? For reference, I am hosting my website on Heroku that is set up with its Nginx buildpack from here, https://github.com/heroku/heroku-buildpack-nginx, and I am not sure if I need to have Heroku install additional dependencies to set up an RTMP server and listen for a stream.

With the following code in NodeJS I'm able to play a webm file served from server:

I am trying to make a simple play/pause application in tkinter. Basically I want to show a video and have a play/pause button underneath.

So, after some research I found this suitable post to show a video using tkinter and opencv: to show video streaming inside frame in tkinter

When using the code, given in the accepted answer to show a video, there is no problem and I don't see any flickering. Here is the code:

I already found a similar question here but that was asked almost 2 years ago. Currently, I am working on a video streaming app for Android and I was thinking if using Firebase to host the videos is a viable option.

I tried using the URL of the video stored in Firebase storage to play the video in my app and it is working just fine.

But I searched online and found that everybody is advising not to use Firebase for the same. Is there any particular reason why Firebase shouldn't be used for this purpose?

P.S. In my case, all the videos that need to be streamed will be in HD and will have a longer time duration.

Any help will be appreciated. Thanks in advance.
