GstVulkan.VulkanInstance.prototype.new

function GstVulkan.VulkanInstance.prototype.new(): {
    // javascript wrapper for 'gst_vulkan_instance_new'
}

Since : 1.18

GstVulkan.VulkanInstance.prototype.check_version

function GstVulkan.VulkanInstance.prototype.check_version(major: Number, minor: Number, patch: Number): {
    // javascript wrapper for 'gst_vulkan_instance_check_version'
}

Check if the configured vulkan instance supports the specified version. Will not work prior to opening the instance with GstVulkan.VulkanInstance.prototype.open. If a specific version is requested, the patch level is ignored.

GstVulkan.VulkanInstance.prototype.create_device

function GstVulkan.VulkanInstance.prototype.create_device(): {
    // javascript wrapper for 'gst_vulkan_instance_create_device'
}

Since : 1.18

GstVulkan.VulkanInstance.prototype.create_device_with_index

function GstVulkan.VulkanInstance.prototype.create_device_with_index(device_index: Number): {
    // javascript wrapper for 'gst_vulkan_instance_create_device_with_index'

GstVulkan.VulkanInstance.prototype.disable_extension

function GstVulkan.VulkanInstance.prototype.disable_extension(name: String): {
    // javascript wrapper for 'gst_vulkan_instance_disable_extension'
}

Disable an Vulkan extension by name. Disabling an extension will only have an effect before the call to GstVulkan.VulkanInstance.prototype.open.

Since : 1.18

GstVulkan.VulkanInstance.prototype.enable_extension

function GstVulkan.VulkanInstance.prototype.enable_extension(name: String): {
    // javascript wrapper for 'gst_vulkan_instance_enable_extension'
}

Enable an Vulkan extension by name. Extensions cannot be enabled until GstVulkan.VulkanInstance.prototype.fill_info has been called. Enabling an extension will only have an effect before the call to GstVulkan.VulkanInstance.prototype.open.

Since : 1.18

GstVulkan.VulkanInstance.prototype.enable_layer

function GstVulkan.VulkanInstance.prototype.enable_layer(name: String): {
    // javascript wrapper for 'gst_vulkan_instance_enable_layer'
}

Enable an Vulkan layer by name. Layer cannot be enabled until GstVulkan.VulkanInstance.prototype.fill_info has been called. Enabling a layer will only have an effect before the call to GstVulkan.VulkanInstance.prototype.open.

Since : 1.18

GstVulkan.VulkanInstance.prototype.fill_info

function GstVulkan.VulkanInstance.prototype.fill_info(): {
    // javascript wrapper for 'gst_vulkan_instance_fill_info'
}

Retrieve as much information about the available Vulkan instance without actually creating an Vulkan instance. Will not do anything while instance is open.

Since : 1.18

GstVulkan.VulkanInstance.prototype.get_extension_info

function GstVulkan.VulkanInstance.prototype.get_extension_info(name: String): {
    // javascript wrapper for 'gst_vulkan_instance_get_extension_info'
}

Retrieves information about an extension.

Will not find any extensions before GstVulkan.VulkanInstance.prototype.fill_info has been called.

Since : 1.18

GstVulkan.VulkanInstance.prototype.get_layer_info

function GstVulkan.VulkanInstance.prototype.get_layer_info(name: String): {
    // javascript wrapper for 'gst_vulkan_instance_get_layer_info'
}

Retrieves information about a layer.

Will not find any layers before GstVulkan.VulkanInstance.prototype.fill_info has been called.

Since : 1.18

GstVulkan.VulkanInstance.prototype.get_proc_address

function GstVulkan.VulkanInstance.prototype.get_proc_address(name: String): {
    // javascript wrapper for 'gst_vulkan_instance_get_proc_address'
}

Performs vkGetInstanceProcAddr() with instance and name

Since : 1.18

GstVulkan.VulkanInstance.prototype.get_version

function GstVulkan.VulkanInstance.prototype.get_version(): {
    // javascript wrapper for 'gst_vulkan_instance_get_version'
}

Retrieve the vulkan instance configured version. Only returns the supported API version by the instance without taking into account the requested API version. This means GstVulkan.VulkanInstance.prototype.check_version will return different values if a specific version has been requested (which is the default) than a version check that is performed manually by retrieving the version with this function.

GstVulkan.VulkanInstance.prototype.is_extension_enabled

function GstVulkan.VulkanInstance.prototype.is_extension_enabled(name: String): {
    // javascript wrapper for 'gst_vulkan_instance_is_extension_enabled'
}

Since : 1.18

GstVulkan.VulkanInstance.prototype.is_layer_enabled

function GstVulkan.VulkanInstance.prototype.is_layer_enabled(name: String): {
    // javascript wrapper for 'gst_vulkan_instance_is_layer_enabled'
}

Since : 1.18

GstVulkan.VulkanInstance.prototype.open

function GstVulkan.VulkanInstance.prototype.open(): {
    // javascript wrapper for 'gst_vulkan_instance_open'
}

Since : 1.18

GstVulkan.VulkanInstance.prototype.handle_context_query

function GstVulkan.VulkanInstance.prototype.handle_context_query(element: Gst.Element, query: Gst.Query, instance: GstVulkan.VulkanInstance): {
    // javascript wrapper for 'gst_vulkan_instance_handle_context_query'
}

If a GstVulkan.VulkanInstance is requested in query, sets instance as the reply.

Intended for use with element query handlers to respond to Gst.QueryType.CONTEXT for a GstVulkan.VulkanInstance.

Since : 1.18

GstVulkan.VulkanInstance.prototype.run_context_query

function GstVulkan.VulkanInstance.prototype.run_context_query(element: Gst.Element, instance: GstVulkan.VulkanInstance): {
    // javascript wrapper for 'gst_vulkan_instance_run_context_query'
}

Attempt to retrieve a GstVulkan.VulkanInstance using Gst.QueryType.CONTEXT from the surrounding elements of element.

Since : 1.18
