| Roadmap Item | |
|---|---|
| Features: | |
| RDK-30256 | [Peacock] [HLS][DASH] thumbnail based scrubbing support (2101) |
| FriendMTS Watermarking Support | |
| Red Button/VCID Support (2101) | |
| TBD | slow motion support (arbitrary trick play speed) |
| Compatibility: | |
| [AAMP][HLS] Improved Compatibility and Formal Specification Compliance | |
| Dolby AC-4 Audio Support | |
| support for muxed HLS with AV fragments containing multiple audio and text tracks | |
| Build support for playing shoutcast music streams in AAMP | |
| [FOG] handle pending ATMOS DASH manifest change (Dolby Specification) | |
| CDAI: | |
| [AAMP] Client Side VOD DAI Optimizations | |
| harden mp4 playback to give option for non-Spotlight ad avail playback that may not have hls/dash equivalents (was [AAMP] support for progressive audio/video playback (such as streaming mp3 music and mp4 video) - phase#2) | |
| Optimization / Robustness: | |
| RDK-26162 | [AAMP] Timed Metadata transmission optimization |
| [AAMP] delays refreshing playlists can interfere with fragment harvesting | |
| [AAMP] Analysis/mitigation for intermittent audio drops with demuxed content | |
| [AAMP] support for Retry-After http header with HTTP 429 "TOO MANY REQUESTS" rate limiting directive | |
| Root Cause Aware Player Switching | |
| [AAMP] initialization fragments needlessly re-downloaded if ramping down and back up, or after transition to ad and back to main content | |
| DELIA-39964 | [AAMP] [HLS/DASH] tune fails if initial audio playlist download fails at tune time (without considering alternate audio profiles/formats) |
| ABR: | |
| [AAMP][HLS/DASH] Restrict Video profile based on display resolution | |
| [AAMP] Capped VBR Support for DASH | |
| Metrics / Profiling: | |
| Error reporting for catastrophic video decoder problems associated with bad streams (including stale PPS/SPS) | |
| AAMP/FOG to report onMediaError event on loss of network connection | |
| [AAMP] collect data to prove benefits of warming edge cache | |
| [AAMP] Pass location data in HTTP upstream header | |
| [AAMP] support for custom http headers configured by Resident app - centrally configured to include user privacy flags | |
| Send IP DAI Triggers to SSIMWAVE | |
| Tech Debt: | |
| DELIA-36671 | [FOG] fragment bitrate reporting mechanism consistency |
| RDK-27619 | [AAMP] Configuration Management Refactoring for Consistency & Control |
| evaluate pros/cons of libxml vs libdash for DASH manifest parsing (FOG/AAMP consolidation) | |
| Configurability: | |
| In case of setDrmConfig api other than passing keySystem and LA_URL details, add capability to pass initData (in base64 format) alongwith initDataType (cenc_pssh,mspr_pro). | |
| Expose ePARAM_VODTRICKPLAYFPS, ePARAM_LINEARTRICKPLAYFPS in UVE | |
| Misc: | |
| IP Linear TSB Internet Interruption Handling | |
| [AAMP][DASH] JSPP control for audio format selection | |
| Media Playback Plugin (Phase 1) | |
| RDK-30409 | Supports subtitles and closed captioning support on IP video streams
|
| DELIA-40048 | [AAMP] tuning partially synchronous, blocking UI (ask: wholly asyn , interruptible tune support) |
| IP VIDEO robustness handling for bad streams (SPIKE) | |
| low latency DASH; https://www.theoplayer.com/blog/low-latency-dash | |
| signaling using emsg messages using a custom key rotation signal to indicate future KIDs | |
| api to query MIME types and codecs (Video, audio, subtitles) supported by player | |
| api to signal platform capabilities to the player so that player can use that when making decisions e.g if there are multiple video adaptation set in different codecs i.e. (HEVC, H.264) present in manifest and platform does not support HEVC, player shall select video adaptation set in H.264 | |
| api to enable/disable/retrieve extended profiling / timing / stats information corresponding to a playback session | |
| getCurrentPosition to support reporting with UTC timestamp for live content | |
| Removal of force encrypted init header workaround in AAMP (dynamic plugging and unplugging of decryptors) | |
| Init header caching for DASH (for ad back to content transition) | |
| refactoring to eliminate need for qtdemux patches | |
| fragmentcollector_mpd.cpp cleanup - room room for improvement here, in terms of improving code quality/readability and streamlining/optimization. | |
| UVE audio selection API enhancements | |
| document and resolve gstreamer discrepancies across SOC venders |
