[MPlayer-users] MPlayer-1.0pre8 detecting wrong aspect ratio

[Raj Kiran Grandhi]

Hi,

I am using mplayer-1.0pre8 on debian testing. I find that mplayer
detects a wrong aspect ratio for .dat files. Also running mplayer with
-identify option reports the aspect ratio as 0.0000. I can force the
aspect ratio using the -aspect option, but it is not very nice.

Here is the output of mplayer-1.0pre7 and mplayer-1.0pre8 for the same file:

MPlayer-1.0pre7 output:
