Returns:
Type
shaka.dash.ContentProtection.Context

(static) parseFromRepresentation(elemsnon-null, callback, context) → (nullable) {string}

Parses the given ContentProtection elements found at the Representation level. This may update the |context|.

Type Definitions

Context

Contains information about the ContentProtection elements found at the AdaptationSet level.
Type:
Properties:
Name Type Attributes Description
defaultKeyId string <nullable>
 The default key ID to use. This is used by parseKeyIds as a default. This can be null to indicate that there is no default.
defaultInit Array.<shakaExtern.InitDataOverride> The default init data override. This can be null to indicate that there is no default.
drmInfos Array.<shakaExtern.DrmInfo> The DrmInfo objects.
firstRepresentation boolean True when first parsed; changed to false after the first call to parseKeyIds. This is used to determine if a dummy key-system should be overwritten; namely that the first representation can replace the dummy from the AdaptationSet.
Source:

Element

The parsed result of a single ContentProtection element.
Type:
Properties:
Name Type Attributes Description
node Element The ContentProtection XML element.
schemeUri string The scheme URI.
keyId string <nullable>
 The default key ID, if present.
init Array.<shakaExtern.InitDataOverride> The init data, if present. If there is no init data, it will be null. If this is non-null, there is at least one element.
