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 102 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 with `PP_OK` when the protection request has been made. This may be before the protection have actually been applied. Call QueryStatus to get protection status. If it failed to make the protection request, the callback is called with `PP_ERROR_FAILED` and there is no need to call QueryStatus().

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

Definition at line 161 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 115 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.
