Subject: [FFmpeg-devel] [PATCH] vulkan: use VK_IMAGE_USAGE_VIDEO_ENCODE_SRC_BIT_KHR for format properties
Date: Mon, 2 Jun 2025 12:54:41 +0200
Message-ID: <20250602105441.3767236-1-vjaquez@igalia.com> (raw)
When fetching image properties to encode, its usage can be specified. According
to documentation:
* VK_IMAGE_USAGE_VIDEO_ENCODE_DST_BIT_KHR: is reserved for future use.
* VK_IMAGE_USAGE_VIDEO_ENCODE_SRC_BIT_KHR: specifies that the image can be used
as an encode input picture in a video encode operation.
This patch changes DST_BIT to SRC_BIT, otherwise it will fail to fetch the
properties at least with proprietary NVIDIA driver (570.123.12)
