MPlayer SB for Windows and macOS (Updated 11 June 2021)

That test clip correctly resizes to 1184x720 for me using SB62 when I ran the command "mplayer mkv-ar-test.mkv".

Very-true, I still suck at doing comprehensive tests

So I conclude they fixed an old regression by creating a new one

OMG, it seems the problem is actually much more complicated than I thought

SB62 has made a correct choice in that case, while Redxii's is wrong.
Different players handle MKV video resizing differently. I tested that video in VLC Media Player which also did 704x704, and MPC-HC did 480x480, which is still a valid choice.

So the logic of the players is this:
SB62 and VLC: Use the correct aspect ratio while not downscaling any pixels.
MPC-HC: Use the correct aspect ratio while not upscaling any pixels.
Redxii's MPlayer: Ignore the correct aspect ratio and display the unadjusted pixels.

The first two choices are good in my opinion especially since the user will typically make the video fullscreen or resize it how they want, so the ratio is all that matters.

SB63 is released! The changes since SB62 are:

• Synchronised with r37363, which fixed audio with DVD sources
• Updated FFmpeg to f845ae0

SB67 is released for macOS, because I couldn't find any other static 64-bit macOS builds
