0c6203c97a all: Don't set AVClass.item_name to its default value 
Unnecessary since acf63d5350adeae551d412db699f8ca03f7e76b9;
also avoids relocations.

36980179a0 fftools/ffplay_renderer: declare function argument as const 
Declaring the function argument as const fixes a warning down the line
that the const parameter is stripped. We don't modify this argument.

a1a6a328f0 fftools/ffplay: add hwaccel decoding support 
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
