XSPF to MP4 Converter

This tool accepts an XSPF playlist and outputs a timeline-oriented MP4 representation or a scaffold for downstream encoding. It does not perform real video encoding; instead, it builds a timeline map from track durations, sequence, and metadata. The core workflow includes XML parsing, duration normalization, and a sequential timeline construction that preserves track order. By providing a synthetic MP4 metadata skeleton or a JSON/CSV timeline export, users can validate timing accuracy and metadata propagation in their pipelines. Target users are developers, QA engineers, and media workflow analysts who need deterministic, auditable results for playlist-driven video workflows. The tool’s value lies in its explicit mapping between XML-based playlist data and a testable video timeline, which supports validation, automation, and integration testing. Core features include input validation, error reporting for malformed XSPF, adjustable frame-rate, and multiple export formats for downstream tools. Typical use cases include validating track sequencing, estimating total duration, and generating a test dataset for video encoding queues. The approach emphasizes reproducibility and traceability, providing clear lineage from input XSPF elements to the resulting timeline or MP4 scaffold.
