# Efficient Live Streaming Transcoding for Reducing Bandwidth and Saving Costs
|
|
|
|
## Introduction
|
|
|
|
In today's digital world, live streaming has become an essential tool for businesses, content creators, and
|
|
individuals alike. With the increasing number of viewers tuning in to watch live streams, it's crucial to optimize
|
|
the streaming experience and cost for everyone, regardless of their internet speed or device capabilities. One
|
|
effective way to achieve this is through live streaming transcoding, a process that can help reduce bandwidth
|
|
and save costs without compromising on video quality. In this blog, we'll explore the benefits of using Oryx
|
|
for efficient live streaming transcoding and how it can lead to significant cost savings.

|
Live streaming transcoding involves converting a live stream from Oryx using FFmpeg into various bitrates and
|
|
resolutions, before pushing it back to Oryx. This process allows for a reduction in bandwidth while maintaining
|
|
the same quality, simply by lowering the bitrate of the stream. As a result, the overall viewing bandwidth is
|
|
decreased, leading to cost savings for both the streamer and the viewer.
|
|
|
|
For instance, consider a live streaming scenario with 10,000 viewers all watching the same 2Mbps bitrate stream.
|
|
By transcoding the stream to 1Mbps, the required bandwidth is reduced to 10Gbps, resulting in a 50% cost saving.
|
|
This not only benefits the content provider but also ensures a smoother streaming experience for viewers with
|
|
varying internet speeds and devices.
|
|
|
|
Stay tuned as we delve deeper into the world of live streaming transcoding, and learn how to harness the power
|
|
of Oryx to optimize your streaming experience and save costs.
|
|
|
|
## Step 1: Create Oryx by One Click
|
|
|
|
Creating an Oryx is simple and can be done with just one click if you use Digital Ocean droplet.
|
|
Please see [How to Setup a Video Streaming Service by 1-Click](./2022-04-09-Oryx-Tutorial.md) for detail.
|
|
|
|
You can also use Docker to create an Oryx with a single command line:
|
|
|
|
```bash
|
|
docker run --restart always -d -it --name oryx -v $HOME/data:/data \
|
|
-p 80:2022 -p 443:2443 -p 1935:1935 -p 8000:8000/udp -p 10080:10080/udp \
|
|
ossrs/oryx:5
|
|
```
|
|
|
|
After creating the Oryx, you can access it through `http://your-server-ip/mgmt` via a browser.
|
|
|
|
## Step 2: Publish a Live Stream to Oryx
|
|
|
|
You can use OBS or FFmpeg to publish a live stream to Oryx. You can also set up HTTPS and publish via WebRTC.
|
|
|
|
|
|
|
|
Once the stream is published, you can preview it using an H5 player or VLC.
|
|
Please see [How to Setup a Video Streaming Service by 1-Click](./2022-04-09-Oryx-Tutorial.md) for detail.
|
|
|
|
## Step 3: Transcode the Live Stream to Lower Bitrate
|
|
|
|
Suppose you've sent an 8Mbps stream to Oryx using OBS, and you can't adjust the bitrate in OBS. This could
|
|
be because the stream is published by a vendor you can't control, or you need to record the original high-resolution
|
|
stream, or some devices like 4K/8K TVs require the high-resolution stream.
|
|
|
|
However, most of your viewers watch the live stream on mobile devices, and they don't need an 8Mbps stream. A 2Mbps
|
|
stream is sufficient for mobile devices, and their bandwidth may only support a 2Mbps bitrate. In this case, you can
|
|
use transcoding to convert the 8Mbps stream into a 2Mbps live stream.
|
|
|
|
|
|
|
|
After transcoding the stream, you can preview the 2Mbps version or forward it to another live streaming platform.
|
|
See [Easily Stream Your RTSP IP Camera to YouTube, Twitch, or Facebook](./2023-10-11-Oryx-Stream-IP-Camera-Events.md)
|
|
for more information. You can also pull the RTMP stream from Oryx and forward it elsewhere.
|
|
|
|
## Check Transcoding Status
|
|
|
|
You can check the transcoding status in the Oryx dashboard.
|
|
|
|
|
|
|
|
You can click the preview link to check the transcoded stream, or forward it to another live streaming platform.
|
|
See [Easily Stream Your RTSP IP Camera to YouTube, Twitch, or Facebook](./2023-10-11-Oryx-Stream-IP-Camera-Events.md)
|
|
for more information.

|
## Cloud Service
|
|
|
|
At SRS, our goal is to establish a non-profit, open-source community dedicated to creating an all-in-one,
|
|
out-of-the-box, open-source video solution for live streaming and WebRTC online services.
|
|
|
|
Additionally, we offer a [Cloud](../cloud) service for those who prefer to use cloud service instead of building from
|
|
scratch. Our cloud service features global network acceleration, enhanced congestion control algorithms,
|
|
client SDKs for all platforms, and some free quota.
|

## Conclusion
|
|
|
|
In summary, we discussed the benefits of live streaming transcoding using Oryx and FFmpeg. Transcoding optimizes
|
|
streaming for viewers with different internet speeds and devices, reduces bandwidth usage, and saves costs. We
|
|
covered setting up Oryx and FFmpeg, creating a configuration file, and pushing transcoded streams back to
|
|
Oryx. Monitoring and adjusting settings is crucial for optimal viewer experience, and transcoding can also
|
|
convert high-resolution streams to lower resolutions for mobile devices.
