RDK-27619[AAMP] Configuration Management Refactoring for Consistency & Control
DELIA-41429evaluate 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:

DELIA-42322[AAMP][UVE] POC for AAMP UVE Test Suite
RDK-23320IP 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 for improvement here, in terms of improving code quality/readability and streamlining/optimization.
