Budling Streaming Server
Day 1 Setup - Sample working setup
Setting up NGINX as a media server
I though most of people already konw what is NGINX. If don’t know what is that here is the Short descrption.
What is Nginx?
Ngxin supports a lot of moudles you can install < list of moudel avalaie on nginx link >. RTMP is ones of them. RTMP stand Real Time Messaging Portocol which can support streaming live vodie and audio content. Using that one we are going to build own straming server to broadcast live content.
For day 1 setup, i will use OBS for live stream and VLC as player to watch Streaming. Recommend to use Linux OS instead of Window in this demo if you are a window user and dont have linxu distru with you, you can easily enable WSL2 for testing.
Run the following scrip to intsll Inginx and RTMP module
sudo apt update && sudo apt upgrade -y
sudo apt install nginx -y
sudo apt install libnginx-mod-rtmp -y
HOw to verify , RTMP module is successfully instlled and working ? Congratulations! You have successfully installed the RTMP module in Nginx. Now you can use Nginx as an RTMP server for live streaming applications.
Required Configuration Chanage on Nginx
As Stream server, we need to capture and play back (forward). Need to setup where we going save our recording and how we can play back those records.
In your nginx configuration file, find application tag block
Do some changes
echo hello
Video Format
By Deafult, Nginx RTMP records in FLV format. you can change video format as you like. I recommend to use HLS format. we will see how we going use that HLS format advance in next day setup.
record_format mp4;
Using VLC as client
Now your Nginx Streaming server is ready, we just left to test out how is it?. For quick demon purpose, we will use VLC as player to watch streaming from obs. Later you can write your onw appliction to watch streaming data and do the exchangement.

Day 2 - Adaptive Bitrate Streaming (ABR) with Nginx RTMP Module
Nginx RTMP module dynamically adjusts the bitrate based on the viewer’s network conditions.
Popular players like JW Player and Flowplayer have built-in support for adaptive bitrate playback.

Video file
Videos may be added to a page by either placing them in your assets/media/ media library or in your page’s folder, and then embedding them with the video shortcode:
{{< video src="my_video.mp4" controls="yes" >}}
Podcast
You can add a podcast or music to a page by placing the MP3 file in the page’s folder or the media library folder and then embedding the audio on your page with the audio shortcode:
{{< audio src="ambient-piano.mp3" >}}

Math
Hugo Blox Builder supports a Markdown extension for $\LaTeX$ math. You can enable this feature by toggling the math option in your config/_default/params.yaml file.
To render inline or block math, wrap your LaTeX math with {{< math >}}$...${{< /math >}} or {{< math >}}$$...$${{< /math >}}, respectively.
Example math block:
{{< math >}}
$$
\gamma_{n} = \frac{ \left | \left (\mathbf x_{n} - \mathbf x_{n-1} \right )^T \left [\nabla F (\mathbf x_{n}) - \nabla F (\mathbf x_{n-1}) \right ] \right |}{\left \|\nabla F(\mathbf{x}_{n}) - \nabla F(\mathbf{x}_{n-1}) \right \|^2}
$$
{{< /math >}}
renders as
$$\gamma_{n} = \frac{ \left | \left (\mathbf x_{n} - \mathbf x_{n-1} \right )^T \left [\nabla F (\mathbf x_{n}) - \nabla F (\mathbf x_{n-1}) \right ] \right |}{\left \|\nabla F(\mathbf{x}_{n}) - \nabla F(\mathbf{x}_{n-1}) \right \|^2}$$Example inline math {{< math >}}$\nabla F(\mathbf{x}_{n})${{< /math >}} renders as $\nabla F(\mathbf{x}_{n})$
.
Example multi-line math using the math linebreak (\\):
{{< math >}}
$$f(k;p_{0}^{*}) = \begin{cases}p_{0}^{*} & \text{if }k=1, \\
1-p_{0}^{*} & \text{if }k=0.\end{cases}$$
{{< /math >}}
renders as
$$ f(k;p_{0}^{*}) = \begin{cases}p_{0}^{*} & \text{if }k=1, \\ 1-p_{0}^{*} & \text{if }k=0.\end{cases} $$Code
Hugo Blox Builder utilises Hugo’s Markdown extension for highlighting code syntax. The code theme can be selected in the config/_default/params.yaml file.
```python
import pandas as pd
data = pd.read_csv("data.csv")
data.head()
```
renders as
import pandas as pd
data = pd.read_csv("data.csv")
data.head()
