Function: validateC2paMerkleSegment()

function validateC2paMerkleSegment(
   segmentBytes, 
   merkleMaps, 
   state?
): Promise<{
  nextState: MerkleSegmentState;
  result: MerkleSegmentValidation;
}>;

Defined in: merkle/validateC2paMerkleSegment.ts:228

Validates a fragmented MP4 VOD media segment against the init manifest's merkle maps (§15.12.2.2). Pure: the caller persists nextState and resets state after a seek.

merkleMaps must be non-empty; the caller is responsible for only calling this in VOD Merkle mode (i.e. after InitSegmentValidation.merkleMaps came back non-empty).

Parameters

segmentBytes

Uint8Array

merkleMaps

readonly MerkleMap[]

state?

MerkleSegmentState

Returns

Promise<{ nextState: MerkleSegmentState; result: MerkleSegmentValidation; }>

Example

it('validates a segment with a correct Merkle proof', async () => {
	const validated = await validateC2paMerkleSegment(segments[0], merkleMaps)

	strictEqual(validated.result.isValid, true)
	strictEqual(validated.result.location, 0)
	strictEqual(validated.result.errorCodes.length, 0)
})
