My OS is openSUSE Leap 15.3 (x86_64).

And, I got the file by;

  $ youtube-dl https://youtu.be/feSVtC1BSeQ

As you know, the file name is Japanese, so I converted the file name

  $ mv FILE.mp4 3,mp4

But, this conversion is just for the posting mail to this mailing
list.

Anyway,

 $ mediainfo 3.mp4

I've installed;

libaom3-3.2.0-lp153.19.2.x86_64
aom-tools-3.2.0-lp153.19.2.x86_64
libaom0-1.0.0-3.6.1.x86_64
libaom-devel-doc-3.2.0-lp153.19.2.noarch
libaom-devel-3.2.0-lp153.19.2.x86_64

And,

 $ ldd /usr/bin/mplayer | grep aom

  libaom.so.3 => /usr/lib64/libaom.so.3 (0x00007f5f9a3e6000)

As, I wrote before, ffplay can play this file flawlessly.

In my environment, the version of ffmpeg is 4.4.1.
I compiled the mplayer with this ffmpeg (4.4.1).

Thanks.
