[SOLVED] mplayer not keeping mkv aspect ratios

When playing MKVs which have Display Width/Height defined, it appears the Movie-Aspect is never being set. Here's sample console output:

mplayer movie.mkv

-snip-

Any ideas as to what is happening? My ~/.mplayer/config contains the following:

# Write your default config options here!

[extension.mkv]
demuxer=mkv

sid=0
ass=yes
embeddedfonts=yes
fontconfig=yes

What gets me is that the Display Height and Display Width are clearly being detected by the demuxer--but it's as if that information isn't making it all the way down to when it starts playing. Thoughts?

EDIT: I should also mention that without the demuxer being set to mkv, I still don't get the AR preserved.

Re: [SOLVED] mplayer not keeping mkv aspect ratios

There was a bug in mplayer for a short time. It's possible the current mplayer in Arch is exactly that buggy version. Try mplayer-svn from AUR.

Ha, that did indeed fix it. Thanks for the heads up!
