Streaming video is a common requirement for modern web applications, especially those dealing with multimedia content.
In this article, we’ll explore how to implement video streaming using the Fiber web framework in the Go programming language. Fiber is known for its speed and simplicity, making it an excellent choice for building high-performance web applications.
Setting Up the Project
Let’s start with setting up the project.
go mod init fiber-streaming-app
then import the go fiber package
go get -u github.com/gofiber/fiber/v2
and the directory structure
Now, let’s create a basic Fiber application
Serve the video file with SendFile method
Now, let’s implement the
streamVideo function. We'll use Fiber's
SendFile method to simplify the process
SendFile is a function in the Golang Fiber web framework that transfers a file from a given path to the client. It is used to serve static files such as images, videos, and documents.
SendFile function is similar to the
Send function, but it is optimized for serving large files.
Implement the Front-end script
Let’s wrote the html which serve the stream endpoint
Now you can run the app by using
go run main.go and you can see the video by accessing the url
Enhancing Video Streaming with Range Requests
To support video streaming with range requests (allowing users to seek within the video), we can implement a more advanced
There should be HTTP response headers that are crucial for correctly handling partial content (range requests) in video streaming.
- Content-Range : Header specifies which part of the entire content is included in the current response. It’s essential for range requests.
Content-Range: bytes 0-499/10000
- Content-Length : Header indicates the size of the content in the current response. For range requests, it should represent the size of the range being served.
- Content-Type : Header specifies the media type of the content. In the context of video streaming, it tells the client that it’s receiving video content and provides information about the video format.
- Accept-Ranges : Header indicates whether the server supports range requests. Setting it to
bytesmeans that the server can handle byte-range requests.
- Status Code 206 (Partial Content): status code (206) informs the client that the server is returning only a portion of the requested content (partial content) in response to a range request.
In this article, we’ve explored how to implement video streaming using the Fiber web framework in Go. Fiber’s simplicity and performance make it a great choice for building web applications, especially those involving multimedia content.
