Bug 1214012

Hi,

I use tumbleweed rootfs on a LicheePi 4A, which is a high performance risc-v SBC. I found that mpv is quite unstable and crash a lot when playing some video files (vlc plays them well on riscv), for example, this ogv file: https://commons.wikimedia.org/wiki/File:Test.ogv :

```
$ mpv -v Test.ogv
[cplayer] Command line options: '-v' 'Test.ogv'
