Since we have hwaccel vulkan and vulkan decoders, now it's possible to
add a renderer to ffplay to interoperate with multiple hardware decoders.
This is a good opportinuity to add hardware decoding support to ffplay.
I'm not meant to reinvent the wheel and duplicate the work of mpv or VLC,
but enhance a simple test tool.
The following patches
1. With minimum effort to add hardware decoding and rendering support.
2. Do render with libplacebo.
3. Works with cuda/nvdec, vaapi and vulkan decoder without CPU copy.
I have tested cuda and vulkan decoders. I don't have devices with vaapi, it
should work I guess. For example,
ffplay -hwaccel cuda -enable_vulkan 8k.mp4
4. It can fallback to CPU copy but with less values.
Known issues:
1. Doesn't take filters into consideration yet.
2. Doesn't suppport subtitles without subtitle filter.
