Every syntax_element
the standard defines.

VTCLab Media Analyzer is a professional-grade tool for deep inspection of video and audio files. It parses container formats and codec bitstreams, displaying every syntax element defined by the relevant standards.

Common use cases

Investigation

Diagnose container and bitstream issues, malformed headers, and unexpected parameters, or figure out what's actually inside a file from an unfamiliar tool or vendor.

Verification

Confirm that encoders, muxers, and pipelines produce output that conforms to the spec and matches the parameters you asked for.

Forensics

Investigate file provenance: identify the producing tool, detect re-encoding, and verify structural integrity of suspect material.

Education

Teach and learn video coding hands-on by exploring real bitstreams down to individual syntax elements.

Key features

Deep bitstream analysis

Every syntax element from container headers down to NAL units, SEI messages, parameter sets (SPS, PPS, VPS), and slice headers — with full field descriptions.

Private by design

All parsing runs locally in your browser via WebAssembly. Files are never uploaded, and results stream in as the file is read.

Synchronized hex view

Inspect raw bytes alongside parsed structure. Click any element to jump to its position in the file.

Streams and packets

Overview of every elementary stream with codec, PIDs, and timing, plus a packet browser with filtering and search.
