VTCLab Media Analyzer — Supported Headers
Below you can find the complete list of container formats, video codecs, audio codecs, and subtitle formats supported by our analyzer. Click on any format with detailed data to see the full element-by-element breakdown.
Each element has a tag showing the level of support our system provides. There are 5 such levels:
| Not supported | This means that analyzer won't show any property inside of this element or won't even recognize this element at all | |
| Partially supported | The analyzer will recognize this element and will display some, but not all properties of element | |
| Supported, no descriptions | The analyzer will display all properties of the element, but only in numeric form | |
| Supported, partial descriptions | The analyzer will display all properties of the element in numeric form, plus some fields will be given a text description. For example, for 'stream_type' field of the MPEG-TS Program Map Table, numeric value '4' will be accompanied with the text 'ISO/IEC 13818-3 Audio' | |
| Supported, full descriptions | All properties that have additional interpretation, defined by the standard, will be displayed with such interpretation |
If you notice some element you're interested in is not fully supported, or not listed at all, don't hesitate to reach out to us at analyzer@vtclab.com (opens in new tab) or create a new issue on our GitHub repository (opens in new tab).
