Recently, I worked on a DRM-enabled streaming architecture and discovered how complicated modern video delivery really is.
Some major lessons:
- DRM is more than encryption
- Safari playback is painful
- CORS issues can break everything
- Token security is critical
- Adaptive bitrate streaming is mandatory
- Debugging playback errors is extremely difficult
The most surprising part was how many systems interact together:
- CDN
- DRM providers
- License servers
- Authentication systems
- Mobile players
- Browser APIs
- Streaming protocols
One small configuration issue can completely stop playback.
I also learned that DRM is about reducing piracy, not eliminating it entirely.
Overall, it was one of the most technically challenging systems I have worked on.
Would love to hear what challenges others faced while working with streaming infrastructure.
