+== Vulkan ==
+
+Vulkan video decoding is a new specification for vendor-generic hardware accelerated video decoding. Currently, the following codecs are supported:
+
+ * Decoding: H.264, HEVC, AV1
+
+The AV1 specification is currently an experimental specification developed in collaboration with the [https://mesa3d.org/ Mesa] project. As such, it should not be expected to be implemented
+on any other drivers currently, but once an official specification is available, the decoder will be ported to use it.
+
+To test decoding, use the following command:
+{{{
+ffmpeg -init_hw_device "vulkan=vk:0" -hwaccel vulkan -hwaccel_output_format vulkan -i INPUT -f null - -benchmark
+}}}
+
+Documentation on how to initialize the device, as well as filtering, is available on our [https://ffmpeg.org/ffmpeg-filters.html#Vulkan-Video-Filters documentation page].
