Live Video Streaming Solution Needed

Mark Weiss 76

I've been trying to replicate the capabilities I enjoyed in 2005 with Windows Media Encoder back then. The ability to stream live video over the internet direct from my own webserver.

I currently run IIS 10 and host 8 websites there.

I'm testing Doug Johnson's pre packaged streaming setup with nginx set up to run on port 8080 alongside IIS 10.
I have OBS streaming to that server. When I open the stream, I get a couple of frames of video and then it freezes, while the audio continues to play.

I've played with everything from bitrates to resolution. I thought it was my cable connection's 10mbs upstream, so I upgraded to 1gbs fiber, but it did not help at all. The problem is exactly the same as with the cable connection.

Here's a screen recording of what I'm observing. I cannot play the video stream locally, but over the public IP address on a different machine it will play a couple of frames and then stop.

Been trying to get this to work since April 2018. Have asked half a dozen different forums. No one seems to understand the problem.

Hi @Mark Weiss
Welcome to Microsoft Q&A!

Could you provide a sample code that reproduces your issue? and please do not include any personal privacy.

Answer 1

Below is the configuration for the streamer:

[code]

user nobody;

multiple workers works !

worker_processes 2;

error_log logs/error.log;

error_log logs/error.log notice;

error_log logs/error.log info;

pid logs/nginx.pid;

events {
worker_connections 8192;

max value 32768, nginx recycling connections+registry optimization =

this.value * 20 = max concurrent connections currently tested with one worker

C1000K should be possible depending there is enough ram/cpu power

multi_accept on;

}

rtmp {
server {
listen 1935;
chunk_size 4096;

application live365 {

live on;

record off;

record all;

record_path /recordings;

push rtmp://c:/xxxxx/xxx/xxx/Stream1;

push rtmp://a.rtmp.youtube.com/live2/0123-4567-89ab-cdef;

hls on;
hls_path /xxxxx/xxx/xxx/;
hls_fragment 3;
hls_playlist_length 60;

uncomment the line below to prevent people from playing using RTMP

deny play all;

}
}
}

http {

include mime.types;

server {

listen 8080;

location / {

root /nginx/srv/;
index index.html;

add_header Cache-Control no-cache; # Disable cache

}
}
}
[/code]

This seems to be a Windows file permission problem:

from the error log for the streamer:

[code]
2022/08/09 12:45:10 [error] 6236#5696: *568 CreateFile() "C:/xxxxx/xxx/xxx/stream1.m3u8" failed (2: The system cannot find the file specified), client: 192.168.0.1, server: , request: "GET /xxx/stream1.m3u8 HTTP/1.1", host: "", referrer: ""
[/code]

And here's the html for the viewer:

[code]
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>HLS Live Streaming</title>
<link href="/js/video-js.css" rel="stylesheet" />
</head>
<body>
<video
id="my-video"
class="video-js"
controls
preload="auto"
width="1280"
height="720"
data-setup="{}">
<source src="/xxx/stream1.m3u8" type="application/vnd.apple.mpegurl" />
</video>
<script src="/js/video.js"></script>
</body>
</html>
[/code]

Hi Mark

First of all, in order to protect the personal privacy of Microsoft Q&A forum users, I deleted the IP address information in your comments,
I looked at the code you provided, as you said, it seems to be a file access issue.
Try not to put the file on the C drive and what type of project your project is？
Could you show the code part using Windows Media Encoder? Please do not include any personal privacy (IP address, phone number, port....).

Your response will be greatly appreciated.

Answer 2

I wonder how to change the hls path when the C: is not specified in the config file?

# push rtmp://c:/nginx/srv/hls/Stream1;  
 # push rtmp://a.rtmp.youtube.com/live2/0123-4567-89ab-cdef;  
  
 hls on;  
 hls_path /nginx/srv/hls/;

I made a copy of the entire nginx folder on D: drive and ran if from there. But I am getting the same results with playback and here's a section of relevant log:

2022/08/09 23:29:41 [error] 7364#7676: *4 CreateFile() "D:/nginx/srv/hls/stream1.m3u8" failed (2: The system cannot find the file specified), client: 192.168.0.101, server: , request: "GET /hls/stream1.m3u8 HTTP/1.1", host: "192.168.0.102:8080", referrer: "http://192.168.0.102:8080/viewer.html"

There are the files it's referring to. They exist, but the server can't find them.

May I ask what type of your project is, because I see the tag of winapi under your question, I need to confirm whether the use of windows-api is causing your problem.

Answer 3

Mark Weiss 76

My application is live streaming from an IIS 10 server, using nginx in parallel to handle the streaming as a sub server.
It seems that Windows is not letting nginx read files from the /hls folder that are being created by nginx as it listens to the stream from Open Broadcaster Software (OBS).

At present, your problem does not seem to be related to windows-api. we remove the tag of windows-api for you first.
