Custom HTTP Authorization Headers
Secure Video Streaming in Unity
With the rise of premium video content in games and XR applications, protecting streams from unauthorized access has become essential. One of the most effective and flexible methods is using Custom HTTP Authorization Headers, especially when working with HISPlayer, the premium Unity Player SDK.
Supported Platforms: Android, WebGL, Windows, Meta Quest, iOS, and more
The Need for Custom HTTP Authorization Headers
Adaptive streaming protocols like HLS and DASH rely on many individual HTTP requests to deliver video segments. Standard browser cookies or query parameters often fall short for secure, cross-origin, or enterprise-grade authentication.
Custom HTTP Authorization Headers solve this by allowing developers to attach authentication tokens (such as Bearer tokens, API keys, or custom schemes) to every request made by the video player.
How safe are Custom HTTP Headers
The security of this approach depends less on the encryption of the video itself and more on the strength of the authentication mechanism:
- It works seamlessly with industry-standard token systems.
- Headers can carry short-lived, scoped tokens that reduce exposure.
- Unlike simple signed URLs, headers support dynamic validation on every segment request.
- When combined with HTTPS, it provides robust protection against interception and unauthorized playback.
This method is widely adopted because it balances strong security with simplicity of implementation.
HISPlayer Unity Player SDK
HISPlayer is the most advanced Unity Video Player SDK optimized for HLS and DASH video streaming support for Custom HTTP Authorization Headers.
Key benefits in HISPlayer:
- Applies headers automatically to all requests (manifests, segments, keys, etc.)
- It is supported across multiple platforms: Android, Meta Quest, Android XR, WebGL, Windows, and more
- Easy integration into Unity projects for both 2D and immersive 3D video playback
- Multistream synchronization
- Specific rendering optimization for high-resolution video streaming features like 4K or 8K streaming, 360°, 3D stereo
To implement it, you need to configure the headers through the HISPlayer controller API before starting playback (exact method names are available in the SDK documentation).
This approach gives Unity developers a clean, performant way to deliver protected premium video content inside games and VR/AR Apps.
