Video playback and UI layout optimization for cross-platform media apps?

Hi all,

We are currently working on optimizing UI layouts and media rendering performance for a cross-platform streaming platform project (Cineby App).

While testing video player integration, catalog rendering (4K/HD streaming assets), and dynamic poster loading across multiple target platforms (Android, PC, Smart TVs), we are exploring best practices for smooth performance and lower memory usage.

For those who have built media-heavy interfaces or embedded media streaming in Unreal Engine / cross-platform apps:

  1. What are your recommended approaches for optimizing dynamic thumbnail caching?
  2. Any specific buffer management strategies you recommend for streaming media without frame drops?
