> Recent versions of libplacebo have required Vulkan versions incompatible
> with lavu Vulkan hwcontexts. While this is expected to change
> eventually, breaking vf_libplacebo every time there is such a transition
> period is obviously undesired behavior, as the following sea of bug
> reports shows.
>
> This commit adds a fallback path for init_vulkan failures which simply
> creates an internal device if there was no user-supplied Vulkan hwaccel.
> Useful when no interop with lavu vulkan hwframes is needed or desired,
> and makes using this filter easier inside certain applications.
