GstVulkan.VulkanBarrierState.prototype.new

function GstVulkan.VulkanBarrierState.prototype.new(device: GstVulkan.VulkanDevice): {
    // javascript wrapper for 'gst_vulkan_barrier_state_new'
}

GstVulkan.VulkanBarrierState.prototype.add_buffer_barrier

function GstVulkan.VulkanBarrierState.prototype.add_buffer_barrier(buffer: GstVulkan.VulkanBufferMemory, src_stage: Number, dst_stage: Number, new_access: Number, new_queue: GstVulkan.VulkanQueue): {
    // javascript wrapper for 'gst_vulkan_barrier_state_add_buffer_barrier'
}

Adds a buffer barrier for buffer to the list of barriers that will be used when calling GstVulkan.VulkanBarrierState.prototype.pipeline_barrier and applied to the buffer when calling GstVulkan.VulkanBarrierState.prototype.commit.

GstVulkan.VulkanBarrierState.prototype.add_image_barrier

function GstVulkan.VulkanBarrierState.prototype.add_image_barrier(image: GstVulkan.VulkanImageMemory, src_stage: Number, dst_stage: Number, new_access: Number, new_layout: Vulkan.ImageLayout, new_queue: GstVulkan.VulkanQueue): {
    // javascript wrapper for 'gst_vulkan_barrier_state_add_image_barrier'
}

Adds an image barrier for image to the list of barriers that will be used when calling GstVulkan.VulkanBarrierState.prototype.pipeline_barrier and applied to the image when calling GstVulkan.VulkanBarrierState.prototype.commit.

Since : 1.30

GstVulkan.VulkanBarrierState.prototype.add_raw_barrier

function GstVulkan.VulkanBarrierState.prototype.add_raw_barrier(barrier: Object, src_stage: Number, dst_stage: Number): {
    // javascript wrapper for 'gst_vulkan_barrier_state_add_raw_barrier'
}

Adds a vulkan memory barrier to the list of barriers performed when using GstVulkan.VulkanBarrierState.prototype.pipeline_barrier. Does not do any tracking of any resources (if any) mentioned in the barrier and does not impact the result of GstVulkan.VulkanBarrierState.prototype.commit.

Currently supported barriers are VkImageMemoryBarrier, VkImageMemoryBarrier2, VkBufferMemoryBarrier, VkBufferMemoryBarrier2, VkMemoryBarrier, and VkMemoryBarrier2.

Since : 1.30

GstVulkan.VulkanBarrierState.prototype.commit

function GstVulkan.VulkanBarrierState.prototype.commit(state: Object): {
    // javascript wrapper for 'gst_vulkan_barrier_state_commit'
}

Commit all the barrier states to their respective GstVulkan.VulkanImageMemory, or GstVulkan.VulkanBufferMemory.

Can fail if the original state of the image/buffer barrier has changed after GstVulkan.VulkanBarrierState.prototype.add_buffer_barrier or GstVulkan.VulkanBarrierState.prototype.add_image_barrier was originally called. The operation (entire command buffer) should be retried in this case.

It is strongly recommended to only call this just before submission of associated the command buffer.

GstVulkan.VulkanBarrierState.prototype.foreach_buffer_unlocked

function GstVulkan.VulkanBarrierState.prototype.foreach_buffer_unlocked(state: Object, func: GstVulkan.VulkanBarrierStateForEachBufferFunc, user_data: Object): {
    // javascript wrapper for 'gst_vulkan_barrier_state_foreach_buffer_unlocked'
}

Call a user provided function for every GstVulkan.VulkanBufferMemory currently locked by self.

Since : 1.30

GstVulkan.VulkanBarrierState.prototype.foreach_image_unlocked

function GstVulkan.VulkanBarrierState.prototype.foreach_image_unlocked(state: Object, func: GstVulkan.VulkanBarrierStateForEachImageFunc, user_data: Object): {
    // javascript wrapper for 'gst_vulkan_barrier_state_foreach_image_unlocked'
}

Call a user provided function for every GstVulkan.VulkanImageMemory currently locked by self.

Since : 1.30

GstVulkan.VulkanBarrierState.prototype.foreach_timeline_semaphore_unlocked

function GstVulkan.VulkanBarrierState.prototype.foreach_timeline_semaphore_unlocked(state: Object, func: GstVulkan.VulkanBarrierStateForEachTimelineSemaphoreFunc, user_data: Object): {
    // javascript wrapper for 'gst_vulkan_barrier_state_foreach_timeline_semaphore_unlocked'
}

Call a user provided function for every GstVulkan.VulkanTimelineSemaphore currently locked by self.

Since : 1.30

GstVulkan.VulkanBarrierState.prototype.lock

function GstVulkan.VulkanBarrierState.prototype.lock(): {
    // javascript wrapper for 'gst_vulkan_barrier_state_lock'
}

Lock all the GstVulkan.VulkanImageMemory, or GstVulkan.VulkanBufferMemory tracked by self.

It is strongly recommended to call this just before submission of the command buffer.

Since : 1.30

GstVulkan.VulkanBarrierState.prototype.pipeline_barrier

function GstVulkan.VulkanBarrierState.prototype.pipeline_barrier(cmd: GstVulkan.VulkanCommandBuffer, dep_flags: Vulkan.DependencyFlags): {
    // javascript wrapper for 'gst_vulkan_barrier_state_pipeline_barrier'
}

Performs the equivalent of vmCmdPipelineBarrier/2 in cmd for the currently stored list of barriers. The list of barriers is then reset to an empty list.

Since : 1.30

GstVulkan.VulkanBarrierState.prototype.reset

function GstVulkan.VulkanBarrierState.prototype.reset(): {
    // javascript wrapper for 'gst_vulkan_barrier_state_reset'
}

Reset self to that of a newly created instance. All stored data is removed.

Since : 1.30

GstVulkan.VulkanBarrierState.prototype.rollback

function GstVulkan.VulkanBarrierState.prototype.rollback(state: Object): {
    // javascript wrapper for 'gst_vulkan_barrier_state_rollback'
}

Rollback all barrier updates performed by GstVulkan.VulkanBarrierState.prototype.commit.

It is strongly recommended to only call this if command buffer submission fails. Do not call this if GstVulkan.VulkanBarrierState.prototype.commit fails.

Since : 1.30

GstVulkan.VulkanBarrierState.prototype.unlock

function GstVulkan.VulkanBarrierState.prototype.unlock(state: Object): {
    // javascript wrapper for 'gst_vulkan_barrier_state_unlock'
}

Unlock all the GstVulkan.VulkanImageMemory, or GstVulkan.VulkanBufferMemory tracked by self.

Since : 1.30

GstVulkan.VulkanBarrierState.prototype.update_buffer_barrier

function GstVulkan.VulkanBarrierState.prototype.update_buffer_barrier(buffer: GstVulkan.VulkanBufferMemory, dst_stage: Number, new_access: Number, new_queue: GstVulkan.VulkanQueue): {
    // javascript wrapper for 'gst_vulkan_barrier_state_update_buffer_barrier'
}

Adds (or updates) the buffer barrier state that will be applied to the buffer when calling GstVulkan.VulkanBarrierState.prototype.commit.

This does not add any barrier to the vulkan command stream. This would need to be done manually or through GstVulkan.VulkanBarrierState.prototype.add_raw_barrier.

Since : 1.30

GstVulkan.VulkanBarrierState.prototype.update_image_barrier

function GstVulkan.VulkanBarrierState.prototype.update_image_barrier(image: GstVulkan.VulkanImageMemory, dst_stage: Number, new_access: Number, new_layout: Vulkan.ImageLayout, new_queue: GstVulkan.VulkanQueue): {
    // javascript wrapper for 'gst_vulkan_barrier_state_update_image_barrier'
}

Adds (or updates) the image barrier state that will be applied to the image when calling GstVulkan.VulkanBarrierState.prototype.commit.

This does not add any barrier to the vulkan command stream. This would need to be done manually or through GstVulkan.VulkanBarrierState.prototype.add_raw_barrier.

Since : 1.30

GstVulkan.VulkanBarrierState.prototype.update_timeline_semaphore

function GstVulkan.VulkanBarrierState.prototype.update_timeline_semaphore(timeline: GstVulkan.VulkanTimelineSemaphore, new_value: Number): {
    // javascript wrapper for 'gst_vulkan_barrier_state_update_timeline_semaphore'
}

Adds (or updates) the image's timeline semaphore value when calling GstVulkan.VulkanBarrierState.prototype.commit.

This does not add any semaphore waits or signal to the vulkan command stream. This would need to be done manually or by using GstVulkan.VulkanOperation.

This can fail if the existing value of image's timeline semaphore does not currently match any previously stored value.
