Shaka Error 6001 ~repack~ < AUTHENTIC >

Through reverse engineering of minified Shaka code (version 4.3.x), we trace the error to the update_() function within manifest_parser.js . Under normal conditions, the updatePeriod() method flushes old segments. However, when the server sends overlapping EXTINF durations and contradictory EXT-X-PART cues, the SegmentIndex ’s fit() function fails to resolve the timeline. This creates a circular reference in the segment object graph. During the next updateManifest() cycle, the recursive resolveTimeline_() function iterates indefinitely until the browser throws a Maximum call stack size exceeded error. Shaka’s global error handler lacks a specific code for recursion overflow and defaults to 6001 .

Adaptive Bitrate (ABR) streaming relies on robust manifest parsing. Shaka Player, a popular open-source library, defines a strict error taxonomy. However, a subset of users has reported a cryptic Error 6001 with the message: “Unexpected state in segment iterator.” This error is not listed in the official documentation [1], suggesting a deeper, possibly environment-specific, fault. shaka error 6001

Under these conditions, the player crashes with Error 6001 on Chromium 122+ and Safari 17.2. Through reverse engineering of minified Shaka code (version
