yay - yet another YUV viewer

yay simply displays 4:2:0, 4:2:2, 4:4:4 YUV and Y-only pictures and sequences.

It tries to find a first match of geometry information like _<width>x<height> somewhere in the path/filename, e.g.

• mobile_352x288.yuv or
• path/to/yuv/mobile_640x480x400frames/file.yuv

yay depends on SDL (simple directmedia layer), which is available for a lot of different platforms.

yay compiles on linux, solaris, macos and mingw/win32.
