GStreamer Making Progress On Vulkan Video Support
Igalia developers have been working on Vulkan Video support for GStreamer, building off earlier work on a GStreamer plug-in that used Vulkan for video uploading/compositing/rendering.
With the new Vulkan Video extensions, Igalia has been working on support for H.264 decoding using Vulkan. That initial work is in place while there still are more improvements planned, including eventually the ability to support H.265 decoding with Vulkan. Vulkan video encoding support within GStreamer is expected to come at a later point.
