Add vulkan renderer via libplacebo.
Simple usage:
$ ffplay -hwaccel vulkan foo.mp4
Use cuda to vulkan map:
$ ffplay -hwaccel cuda foo.mp4
Create vulkan instance by libplacebo, and enable debug:
$ ffplay -hwaccel vulkan \
-vulkan_params create_by_placebo=1:debug=1 foo.mp4
---
v5:
1. add vulkan_params option.
2. vulkan instance can be create by hwcontext or libplacebo.
v4: add more optional extensions
v3: shared vulkan instance between libplacebo and hwcontext
You did it the other way. Instead of creating a device through libplacebo,
just create a Vulkan device via the hwcontext, and use it for libplacebo.
I have done both:
1. create vulkan device by hwcontext and import to placebo
2. create vulkan device by placebo and pass to hwcontext
It's controlled by -vulkan_params create_by_placebo=1(0). Default is the
first behavior.
Did I miss something?
