mplayer on x32: working❣

Hi everyone,

I just installed mplayer on my Debian/x32 desktop and can
confirm it’s working fine. Thanks a lot for bringing it back!

Some observations:

• the default -ao alsa does not work because it uses an ioctl
  that appears to be broken on x32 (and possibly some MIPS
  variants), as ioctls are not yet triarch’d (fallback to
  -ao sdl:aalib also fails)

  ⇒ fix:
	tglase at tglase:~ $ cat .mplayer/config

  This works perfectly.

  Can we address this somehow on the userland side until the
  kernel is fixed? Maybe make OSS default on x32 or, better,
  adding OSS as fallback to try when ALSA fails?

• there were some performance concerns because we disabled
  asm code in many codecs on x32; I just displayed a 480x360
  MP4 youtube video, either in window or on 1280x1024 fullscreen,
  with about 5% constant CPU usage (AMD Phenom(tm) II X4 965 Processor
  at 3.4 GHz), which I think is okay
