player.addEventListener('error', (event) => if (event.detail.code === 6001) console.warn('Shaka Error 6001: Recursive manifest detected. Resetting...'); player.unload(); setTimeout(() => player.configure('manifest.hls.ignoreManifestUpdates', true); player.load(originalManifestUri); setTimeout(() => player.configure('manifest.hls.ignoreManifestUpdates', false); , 10000); , 1000); ); Shaka Error 6001 is not a standard player error but a symptom of a runtime recursion fault triggered by aggressive low-latency HLS partial segments. Since the Shaka maintainers have not assigned a permanent code to this fault, developers must implement defensive application-layer recovery. Future work includes patching the Shaka player to catch RangeError natively and map it to a documented code (e.g., 6010 – “Manifest recursion limit”). shaka error 6001

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 . Author: [Generated AI] Date: April 14, 2026 player

Shaka Error 6001 is an undocumented runtime exception observed in streaming applications utilizing the Shaka Player library. While the Shaka Player typically reports error codes within the 1000-5999 range (e.g., 1001 for network, 2001 for manifest parsing), empirical evidence from production logs indicates the emergence of a non-standard 6001 error under specific low-latency HLS (LL-HLS) and fragmented MP4 (fMP4) conditions. This paper hypothesizes that Error 6001 originates not from the player’s core logic but from a JavaScript engine’s internal out-of-memory (OOM) or recursion limit violation, triggered by an infinite or self-referential manifest update loop. We propose a detection mechanism and a client-side mitigation strategy. Future work includes patching the Shaka player to

Under these conditions, the player crashes with Error 6001 on Chromium 122+ and Safari 17.2.
