+Rebuild media samples from `.srs` metadata and a source media file. Extracts track signatures, reconstructs the sample byte-for-byte, and verifies the result against the expected CRC32 and file size. Supports the same container formats as the SRS Creator. ISO/IMG images can be used as the media source — for VOB-based samples, the matching title set is automatically detected using track signatures.
