VTCLab Media Analyzer

[ivanb]

Hello everybody, I am the author of VTCLab Media Analyzer (https://media-analyzer.pro).

It's an in-browser tool to take a quick look into the internals of video files. It shows mostly high-level headers info, no macroblocks and coding tree units. Can be used to examine things like container metadata, VPS/SPS/PPS/Slice headers, SEI messages, etc. Requires no installation, just a more or less fresh browser with WebAssembly support.

Here are the news from the most recent version:

v0.2.4 2023-07-06

* MP4: Support 'schm', 'sinf', 'schi', 'sgpd' 'sbgp', 'mehd', 'trex', 'sidx', 'mfhd', 'tfhd', 'tfdt', trun', 'mdcv', 'clli', 'cclv' boxes
* TS: Add new PMT stream_types and descriptors from ISO/IEC 13818-1:2022
* TS/MP4/AVC/HEVC/VVC: Add enum names for AspectRatio, ChromaFormat, ColourPrimaries, TransferCharacteristics, MatrixCoefficients and HDR_WCG_idc fields, human-friendly descriptions for luminance- and color-related fields
* TS: Add DOVI_video_stream_descriptor support
* TS: Recognise SCTE-35 streams, add 'cue_identifier_descriptor' support
* VVC: Add support for several SEI messages, list names for others
* VVC: APS header support, picture_header_structure draft
* HEVC: Add names for Dolby Vision "Unspecified 62" and "Unspecified 63" NAL units
* SEI: Add Kvazaar, Elemental info from SEI Unregistered messages
* RBSP reader for AVC/HEVC/VVC: Fix incorrect behavior in some corner cases

Full Version History is here or on GitHub

Glad to hear any feedback
