08bebeb1be Revert "all: Don't set AVClass.item_name to its default value"
Some callers assume that item_name is always set, so this may be
considered an API break.

This reverts commit 0c6203c97a.

564a15b2ee fftools/ffplay_renderer: Add device selection support
The device can be selected by GPU name or index. For example,

ffplay -hwaccel cuda \
	-vulkan_params device="NVIDIA GeForce RTX 3060" \
	foo.mp4

ffplay -hwaccel cuda -vulkan_params device="0" foo.mp4

Please note that select device by index only supported by hwcontext,
not by libplacebo.

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
