Codec support (H.264, HEVC, AV1, AAC, …) follows the device or browser — the players use the platform’s native decoders.

On the web, DASH plays on Media Source Extensions through dash.js — the same API, events, menus, live/DVR handling and DrmConfig as HLS, with the stream type you declare on the item. Safari has no DASH path: serve it HLS (CMAF lets one packaging feed both). An .mpd URL, or mimeType: "application/dash+xml" on an extensionless manifest URL, selects the DASH engine. dash.js ships inside the ogplayer package and loads only when a DASH item plays: the ES module build imports it as a separate chunk on its own, while <script> pages and packaged TV apps add ogplayer.dash.global.js from the package’s dist/ next to the SDK bundle (see the web and smart TV quick starts). HLS-only pages never download it.

Low-latency HLS plays at the latency the playlist asks for: the players follow its PART-HOLD-BACK as their target, and the LIVE chip, the DVR window, the behind-live state and going to the live edge all work on parts. On the web the default profile plays it in hls.js’s low-latency mode; the TV profile (platformProfile: "tv") keeps low-latency mode off and plays such streams at the regular delay. See Live & DVR.

Not supported

Format	Why
DASH on iOS	AVFoundation has no DASH pipeline — use HLS (CMAF lets one packaging serve both)
WebM on iOS	not an AVFoundation container
Smooth Streaming	legacy format, not included on any platform
RTMP / RTSP	contribution protocols, out of scope for a playback SDK

DRM systems

DRM	Android	iOS	Web
Widevine	✅ (default)	—	✅ Chrome · Firefox · Edge · Android browsers · Tizen / webOS via `ogplayer/tv`
PlayReady	✅	—	✅ browsers and TV sets with a PlayReady CDM — Edge; Tizen / webOS via `ogplayer/tv`
FairPlay	—	✅	✅ Safari (macOS / iOS)
ClearKey	✅	—	—

On the web, one DrmConfig can carry all three systems — the SDK engages whichever the visitor’s browser supports. DASH items use Widevine and PlayReady (the same DrmConfig, token provider, renewal events and 4000–4005 codes as HLS); FairPlay pairs with HLS on Safari.

Encryption schemes: cenc and cbcs are supported wherever the platform supports them (CMAF/cbcs works across all three, which is how one encrypted stream can serve every platform).
