Jan 1, 2026January 2026 (rdkcentral/aamp) focused on stabilizing playback, expanding streaming capabilities, and strengthening test infrastructure. The work delivered several high-impact features, addressed critical stability issues, and advanced security/maintainability practices, positioning the project for more reliable releases and easier future enhancements. Key features delivered: - Single Playbin follow-up R&D: ongoing integration work to enable reliable single playbin playback with targeted fixes to the gstTestHarness segfaults on XiOne. - HTTP/1.1 Chunked Transfer support in GetFile: implemented app-managed chunked transfer mode with a state machine, parsing utilities, and tests; exposed behind a runtime config to enable exploratory use cases without Content-Length. - EWMA bandwidth estimator testing: introduced and validated a new bandwidth estimation path via NetworkBandwidthEstimator and DownloadContext classes to improve adaptive streaming decisions. - GStreamer test harness robustness: follow-up hardening to strengthen lifecycle handling, including destructor tracking and comprehensive Pipeline::Reset improvements, reducing crashes during stop/restart cycles. - TLS 1.3 for CDN downloads: enabled TLS 1.3 negotiation for CDN downloads to improve security and future-proof connections. Major bugs fixed: - MP4 demuxer hardening and crash fixes: added bounds checks, 64-bit size support, sanitized crash fixes, and expanded unit tests to improve stability. - GStreamer test harness memory leak fix: cleanup of global state/data structures to prevent memory retention across tests. - GStreamer test harness idle callback CPU hog: introduced a delay to avoid 100% CPU usage on idle, reducing resource contention during heavy test runs. - Range-based download issues with local content: corrected URL construction for file:// paths to fix range requests on local content. - Revert Rate Correction during RW on LLD: reverted change that enabled rate correction during RW to preserve test stability. - Unified SetAC4Tracks revert: reverted unified SetAC4Tracks support to align with current feature strategy. - Xcode Clean Build Folder error building aampcli: resolved issues when cleaning the build folder in Xcode to streamline local development. - GStreamer test harness seek before load fixes: addressed video freezes by ensuring proper timing of seek operations in the harness. Overall impact and accomplishments: - Increased playback reliability and streaming robustness, reducing hard errors during transitions and test cycles. - Improved security posture for CDN-based downloads with TLS 1.3 negotiation. - Strengthened test infrastructure, enabling more deterministic test runs, better memory management, and faster debugging. - Improved maintainability and readability through code quality improvements and naming convention standardization. Technologies/skills demonstrated: - C/C++ development with GStreamer integration and media pipeline lifecycle management. - Network protocols and streaming concepts, including chunked transfer and bandwidth estimation. - Security hardening (TLS 1.3) and runtime-config enabled feature toggles. - Advanced testing practices, RAII-based resource management, and memory leak prevention. - Codebase maintainability improvements (snake_case to camelCase refactor).

Key features delivered: - DRM Demuxing Support and aampcli Parse Command: Added parsing support for DRM-specific MP4 boxes (pssh, senc) during demuxing and introduced a new aampcli parse command to demux encrypted headers and segments. Impact: enables secure content processing and easier troubleshooting for encrypted streams. - Code Quality and Maintenance Improvements: Consolidated code-quality improvements including spelling fixes, naming consistency, minor compilation cleanups, and improved logging and memory handling (e.g., gst_buffer_new_memdup) to improve maintainability and readability. Major bugs fixed: - Crash/Fault Tolerance in Fake Private Instance: Fixed crash in FakePrivateInstanceAAMP.cpp by simplifying implementation, correcting string literals, and ensuring download status defaults. Impact: increased runtime stability and reliability in non-production test scenarios. - Regression Fixes for Media Processing and Testing: Reverted changes that caused regressions in tune delay, L2 trickplay tests, and related media processor initializations to restore stable behavior. - Stop Path Synchronization and Destruction Race Fix: Prevented generation of state-change events during player destruction by introducing an isDestructing flag to Stop, ensuring consistent idle state after flushing. Overall impact and accomplishments: - Significantly reduced crash surfaces and regression risk, improving overall media playback stability and test reliability. - Strengthened maintainability with extensive code-quality improvements, enabling faster future iterations. - Added DRM support enhancements and CLI tooling to streamline debugging and secure content handling. Technologies/skills demonstrated: - C++14 extension awareness, memory management optimizations, and robust state handling. - DRM demuxing concepts (pssh, senc) and integration in demuxing pipeline. - CLI tooling enhancements and improved logging for operational visibility.
