timeout	max timeout untill which to wait for cdm key generation.

Return values

Pointer to DrmData containing license request.

Implements AampDrmSession.

Definition at line 219 of file opencdmsessionadapter.cpp.

◆ aampDRMProcessKey()

int AAMPOCDMSessionAdapter::aampDRMProcessKey	(	DrmData *	key,
		uint32_t	timeout
