Add support for HLS com.apple.streamingkeydelivery through MSE/EME implementation. Close #3346 ## Tests Tested on: - Mac 11.6 Safari 15.2 - iOS 15.2 Safari 15.2 - Mac 11.6 Chrome 96 (for potential regressions on Widevine keySystem) | Mode | DRM API | TS | CMAF (mono-key and multi-keys) |---|---|---|---| | file | EME | ✅ | ✅ | | file | Legacy-prefixed | ✅ | ✅ | | media-source | EME | **mux-js**: `encrypted` never fired<br />**real MSE**: `encrypted` event received, but with incorrect `sinf` initData (*1) | ✅ | | media-source | Legacy-prefixed | **mux-js**: `webkitneedkey` never fired<br/>**real MSE**: TBD | 🔴 fails to append media segment to SourceBuffer (init segment ok) `(video:4) – "failed fetch and append: code=3015"` | ## Support table | Mode | DRM API | TS | CMAF (mono-key and multi-keys) |---|---|---|---| | file | EME | ✅ | ✅ | | file | Legacy-prefixed | ✅ | ✅ | | media-source | EME | 🚫 `4040: HLS_MSE_ENCRYPTED_MP2T_NOT_SUPPORTED` | ✅ | | media-source | Legacy-prefixed | 🚫 `4041: HLS_MSE_ENCRYPTED_LEGACY_APPLE_MEDIA_KEYS_NOT_SUPPORTED` |🚫 `4041: HLS_MSE_ENCRYPTED_LEGACY_APPLE_MEDIA_KEYS_NOT_SUPPORTED` | ⚠️ Use EME APIs with multi-keys CMAF makes the video stalling with the audio continuing alone after a short time (~3 minutes in the stream, could be shorter, could be longer). Didn't find an explanation to that yet. I've observed the same behaviour with hls.js code so I don't think this is a player issue.
