Since the commit 27590d86534b0c94f12b9a206410f475fb008e72, mpv fails to
use vulkan decoding. Vulkan decoding using ffmpeg directly works but, for
some reason, with mpv it prints "[ffmpeg] Vulkan: No memory type found for
flags 0x1" and fails.
There have been some updates since then, like
60fc0288ae39c3294091c2a4e06816836be95740 which is pretty close to the
solution @haasn gave to me, but they are not enough apparently. The only
patch fixing the issue is this one:
{{{
--- a/libavutil/hwcontext_vulkan.c
+++ b/libavutil/hwcontext_vulkan.c
@@ -2019,6 +2019,8 @@ FF_ENABLE_DEPRECATION_WARNINGS
if (!hwctx->unlock_queue)
hwctx->unlock_queue = unlock_queue;
+ vk->GetPhysicalDeviceMemoryProperties(hwctx->phys_dev, &p->mprops);
+
p->vkctx.device = ctx;
p->vkctx.hwctx = hwctx;
}}}
I don't know why that works. As I said @haasn was kind enough to propose
that solution and it is the only fix I found so far.
You can find the full log attached.
