Software tools reference

This chapter contains reference documentation and basic usage examples for each of the command line tools included with the VC-2 conformance software. In summary, these are:

vc2-test-case-generator

Generates test cases (i.e. pictures and bitstreams) for testing the conformance of VC-2 encoders and decoders.

vc2-bitstream-validator

Validates the conformance of a VC-2 bitstream and produces a reference decoding.

vc2-picture-compare

Compares pairs of pictures.

vc2-picture-explain

Produces informative explanations of the video formats written and accepted by the VC-2 conformance software. (See Video file format).

vc2-bitstream-viewer

Produces a human-readable low-level description of VC-2 bitstreams.
