class	`config_set_decode_caps` (config, caps)
class	`new` (device)

device	`GstVulkan.VulkanDevice`	r	the `GstVulkan.VulkanDevice` to allocate images from

class GstVulkan.VulkanImageBufferPool(**kwargs)¶

New in version 1.18.

classmethod config_set_allocation_params(config, usage, mem_properties, initial_layout, initial_access)¶

Parameters:

config (Gst.Structure) – the Gst.Structure with the pool’s configuration.
usage (Vulkan.ImageUsageFlags) – The Vulkan image usage flags.
mem_properties (Vulkan.MemoryPropertyFlags) – Vulkan memory property flags.
initial_layout (Vulkan.ImageLayout) – Initial Vulkan image layout.
initial_access (int) – Access flags for the layout transition if initial_layout is not VK_IMAGE_LAYOUT_UNDEFINED or VK_IMAGE_LAYOUT_PREINITIALIZED.

Sets the usage and mem_properties of the images to setup.

New in version 1.24.

classmethod config_set_decode_caps(config, caps)¶

Parameters:

config (Gst.Structure) – the Gst.Structure with the pool’s configuration.
caps (Gst.Caps) – Upstream decode caps.

Decode caps are used when the buffers are going to be used either as decoded dest or DPB images.

New in version 1.24.

classmethod new(device)¶

Parameters:: device (GstVulkan.VulkanDevice) – the GstVulkan.VulkanDevice to use
Returns:: a Gst.BufferPool that allocates buffers with #GstGLMemory
Return type:: Gst.BufferPool
