Detailed Description

The PPB_OutputProtection_Private interface allows controlling output protection.

Example:

op = output_protection->Create(instance);
output_protection->QueryStatus(op, &link_mask, &protection_mask,
                               done_callback);

In this example, the plugin wants to enforce HDCP for HDMI link.

if (link_mask & PP_OUTPUT_PROTECTION_LINK_TYPE_PRIVATE_HDMI) {
  output_protection->EnableProtection(
      op, PP_OUTPUT_PROTECTION_METHOD_PRIVATE_HDCP, done_callback);
}

After EnableProtection() completes, the plugin has to query protection status periodically to make sure the protection is enabled and remains enabled.

PP_Resource(* PPB_OutputProtection_Private_0_1::Create)(PP_Instance instance)

Create() creates a new PPB_OutputProtection_Private object.

[in] instance A PP_Instance identifying one instance of a module.

Returns: A PP_Resource corresponding to a PPB_OutputProtection_Private if successful, 0 if creation failed.

Definition at line 101 of file ppb_output_protection_private.h.

int32_t(* PPB_OutputProtection_Private_0_1::EnableProtection)(PP_Resource resource, uint32_t desired_protection_mask, struct PP_CompletionCallback callback)

Set desired protection methods.

When the desired protection method(s) have been applied to all applicable output links, the relevant bit(s) of the protection_mask returned by QueryStatus() will be set. Otherwise, the relevant bit(s) of protection_mask will not be set; there is no separate error code or callback.

Protections will be disabled if no longer desired by all instances.

Parameters

[in]	resource	A `PP_Resource` corresponding to a `PPB_OutputProtection_Private`.
[in]	desired_protection_mask	The desired protection methods, which is a bit-mask of the `PP_OutputProtectionMethod_Private` values.
[in]	callback	A `PP_CompletionCallback` to be called when the protection request has been made. This may be before the protection have actually been applied. Call QueryStatus to get protection status.

Returns: An int32_t containing an error code from pp_errors.h.

Definition at line 157 of file ppb_output_protection_private.h.

PP_Bool(* PPB_OutputProtection_Private_0_1::IsOutputProtection)(PP_Resource resource)

IsOutputProtection() determines if the provided resource is a PPB_OutputProtection_Private.

Parameters

[in] resource A PP_Resource corresponding to a PPB_OutputProtection_Private.

Returns: PP_TRUE if the resource is a PPB_OutputProtection_Private, PP_FALSE if the resource is invalid or some type other than PPB_OutputProtection_Private.

Definition at line 114 of file ppb_output_protection_private.h.

int32_t(* PPB_OutputProtection_Private_0_1::QueryStatus)(PP_Resource resource, uint32_t *link_mask, uint32_t *protection_mask, struct PP_CompletionCallback callback)

Query link status and protection status. Clients have to query status periodically in order to detect changes.

Parameters

[in]	resource	A `PP_Resource` corresponding to a `PPB_OutputProtection_Private`.
[out]	link_mask	The type of connected output links, which is a bit-mask of the `PP_OutputProtectionLinkType_Private` values.
[out]	protection_mask	Enabled protection methods, which is a bit-mask of the `PP_OutputProtectionMethod_Private` values.
[in]	callback	A `PP_CompletionCallback` to run on asynchronous completion of QueryStatus(). This callback will only run if QueryStatus() returns `PP_OK_COMPLETIONPENDING`.

Returns: An int32_t containing an error code from pp_errors.h.
