ABR Viewer

The ABR viewer ingests a streaming manifest URL and parses the bitrate ladder for DASH or HLS. It computes core metrics such as min, max, and average bitrate, segment count, and startup delay. The tool also estimates rebuffer times under a defined network profile and reports a concise quality score. By offering a focused, data-driven view of ABR configurations, it helps engineers validate ladder coverage and identify gaps that may cause buffering or poor user experiences. Conceptually, it treats streaming quality as a function of available tracks, segment duration, and network conditions, delivering actionable metrics without requiring full playback instrumentation. Beneficiaries include platform operators, video engineers, and QA analysts who need quick, repeatable checks of ABR configurations across manifests and variants. Unique value lies in its minimal input requirement (a single manifest URL) paired with rigorous parsing and structured outputs suitable for automation, dashboards, or CI pipelines. Core features include manifest parsing, ladder extraction, metric computation, basic error handling for unsupported formats, and export-ready results. Use cases span pre-release validation of new streams, regression checks after codec changes, and cross-manifest comparisons for consistency across resolutions and bitrates.
