Struct VulkanQueueLock 

pub struct VulkanQueueLock { /* private fields */ }

Serializes one shared Vulkan queue family across FFmpeg and the renderer.

Takes the same recursive lock FFmpeg takes around its submissions. Only contexts made by create_vulkan_device_context have it.

Implementations

impl VulkanQueueLock

pub fn new( device: AVHWDeviceContext, queue_family: u32, ) -> Result<Self, BridgeError>

Locks submissions to queue_family on device.

Errors

Returns an input error unless device came from create_vulkan_device_context and has a lock for queue_family.

pub fn lock(&self) -> VulkanQueueGuard<'_>

Holds the queue lock until the guard drops; the guard stays on this thread.

pub unsafe fn raw_lock(&self)

Acquires the queue lock without a guard, for adapters with their own lock/unlock protocol.

Safety

The calling thread must release it with exactly one Self::raw_unlock, in reverse order of its other holds on this lock.

pub unsafe fn raw_unlock(&self)

Releases a hold taken by Self::raw_lock.

Safety

The calling thread must hold the lock from an unreleased Self::raw_lock, and this must be its most recent hold. An unbalanced release lets two submissions reach the queue at once.
