[FFmpeg-devel] [PATCH 04/23] avutil/hwcontext_vulkan: Allocate public and priv device hwctx together
Andreas Rheinhardt
andreas.rheinhardt at outlook.com
Mon Feb 12 02:03:16 EET 2024
This is possible because the lifetime of both coincide.
Besides reducing the number of allocations this also simplifies
access to VulkanDevicePriv as one no longer has to
go through AVHWDeviceInternal.
