Both HLS and MPEG-DASH solve the same problem — adaptive, chunk-based streaming over HTTP — with different origins and slightly different technical approaches.
| Factor | HLS | MPEG-DASH |
|---|---|---|
| Origin | Apple | MPEG standards body |
| Manifest format | M3U8 | MPD (XML) |
| Codec flexibility | Traditionally H.264/H.265-focused | Codec-agnostic |
| Device support | Extremely broad, especially Apple devices | Strong on browsers and Android |
Does it matter to you as a viewer?
Not in any way you'll interact with directly — your player app and the server negotiate this automatically. The distinction mainly matters to the engineers building streaming infrastructure.
