Why HLSAnalyzer.com?
Frequently asked questions
Can I run a free stream check?
Yes. You can run a few checks without an account. A free account includes 15 stream checks per month, and each check runs for up to 15 minutes. Paid validation plans extend a single check to 3 hours.
How does validation differ from continuous monitoring?
Validation runs a time-limited analysis of a stream you submit, which is useful while developing or troubleshooting. Continuous monitoring keeps checking a stream over time and sends the outage alerts you configure, with results available through the dashboard and the REST API. See monitoring plans.
What counts as one monitored item?
Monitoring is counted per HLS media playlist or DASH representation, rather than by channel name. A channel with several renditions can therefore use more than one monitored item. Current plans and quantities are listed on the pricing page.
How are submitted stream URLs handled?
Our Privacy Policy describes how we handle the data you submit. Submit only streams you own or control, and use a test stream when evaluating the service. If you have a specific question about a stream URL or its credentials, contact us.
How do I contact support?
Use the contact form and describe the stream and the problem you are seeing. Including the stream URL and the time the problem occurred helps us investigate.
Detect stream delivery problems and investigate their causes
Streaming quality directly affects your viewers. HLSAnalyzer.com monitors and validates HLS and MPEG-DASH streams so that delivery problems surface to your team, with the detail needed to investigate them, rather than arriving first as a customer complaint.
Continuous HLS & DASH Monitoring: Our 24x7 monitoring detects stream delivery problems and records the surrounding detail so they can be investigated. Our software performs extensive conformance tests for both HLS (RFC 8216) and DASH (ISO/IEC 23009-1) streams, helping you check playback conformance across a variety of platforms. These same tests form the foundation of our HLS Server Certification program, an independent conformance-testing program for streaming infrastructure.
Advanced Transport Stream Extraction
HLSAnalyzer.com offers advanced transport stream extraction capabilities for SCTE-35 cue markers, CEA-608 closed captions, and CEA-708 closed captions directly from MPEG-TS segments within your HLS streams. These capabilities extend our monitoring platform beyond playback validation to support compliance review, accessibility checks, and content analysis workflows. (Note: Transport stream extraction is available for HLS streams with MPEG-TS segments. DASH streams use fMP4 containers with different extraction methods.)
Real-Time Caption and Cue Access: Captions and SCTE-35 markers are continuously extracted and made available through our RESTful API in both polling and Server-Sent Events (SSE) modes, enabling real-time integration with monitoring dashboards, compliance reporting systems, and AI/ML text processing pipelines. Use cases include accessibility monitoring, programmatic advertising verification, content search indexing, sentiment analysis, and automated metadata generation.
Historical Archiving: Extracted CEA-608/708 captions and SCTE-35 signals can be optionally archived for up to 30 days, providing compliance audit trails and historical analysis capabilities. This archival service ensures you maintain comprehensive records for regulatory reporting and technical troubleshooting.
Trust But Verify
Trust is the cornerstone of any digital broadcasting service. HLSAnalyzer.com gives you the delivery records needed to check whether ad markers and stream delivery behaved as expected. We offer extensive logging and tracking services for ad-insertion markers and quality of service delivery of streams. Beyond monitoring, our HLS Certification service reports on the selected test profile, the checks performed, and the results—useful when demonstrating conformance to partners and stakeholders.
SCTE-35 Outage Alerts and Historical Reports: Ad markers are a well-known concept in the digital broadcasting industry. These markers are generally inserted at the origin and subsequently used by third-party services that offer dynamic ad insertion. Both HLS and DASH specifications facilitate dynamic advertising insertion through SCTE-35 markers—via playlist tags in HLS and EventStream elements in DASH. Our system diligently tracks SCTE-35 markers across both formats and alerts you to any discrepancies in ad marker presence or ad segment durations. This level of scrutiny is vital for upholding the integrity of dynamic ad insertions, fostering trust between you and your advertisers. The SCTE-35 logging capabilities can help identify problems at multiple points in the content-delivery ecosystem.
Historical Logs: Access to detailed historical logs equips you with the data necessary for thorough verification. This transparency is key in maintaining and strengthening trust in your streaming services. Logs can be requested as a post-processed summary of event data or as the raw individual events recorded by the analyzer. Historical logs will be available for 90 days.

Our Commitment to Quality Assurance
If you hate embarrassing customer calls about network outages, we hate it even more! After all, as the experts in monitoring, it raises an important question: who monitors the monitoring service?
Well, we employ multiple strategies in monitoring ourselves. Firstly, we have automated scripts examining every aspect of our customer’s monitoring instances, making sure every media playlist is continuously updated, ensuring our website responsiveness is correct, and that all other cloud functions are operating as expected.
Our second strategy is to offer our analyzer service free of charge. Thus far, HLSAnalyzer.com has been used successfully as an online HLS and DASH validator for analyzing streams to date. The fact that we help analyze so many streams free of charge has strengthened the stability of our core monitoring engine by exposing it to different types of error scenarios and streaming conditions. We provide the reliability that streaming services need to operate with confidence, minimizing the risk of customer complaints.
Lastly, to complement our monitoring services, we've developed a rich API for accessing all HLS and DASH monitoring functions. This powerful tool is not just for our internal use; it's available to all our clients. Our browser-based offering utilizes the same underlying API calls, ensuring a consistent and seamless experience for users who prefer a more technical approach. This API has been in production with multiple customers for several years and is continuously refined based on user feedback. Sample code and Python API examples are available in our open-source GitHub repository, making integration straightforward for developers. It's a key part of our commitment to providing versatile and robust monitoring solutions that meet diverse client needs.
