[Mplayer-dev-eng] Wanted features!

[Per Wigren]

Hi!

When opening an ASF file in MS Mediaplayer or Avifile, it immediatly says how 
long it is. Isn't there a way to scan the asf (without doing the 
frame-decoding) to tell how long it is? (and maybe also average fps?)  What 
about WMV-files? (I have no .wmvs here right now to check)

Thanks
Per Wigren
