Video Browser is a lightweight MP4 metadata and sample-location reader that works on a stream rather than loading the whole file. The documented user flow is to provide a video stream, validate and parse MP4 metadata, then inspect tracks and enumerate or decode samples. The diagram follows the sampled parser and its format structures; the test/benchmark harness is excluded. README capability coverage is limited to MP4, the only format it documents. Unsampled internals are represented only where supported by the source index.
