View Full Version : Can't open VC1 with MeGui (Win7)

Brand new Win7 installation. Installed FFDShow, Haali, used the Win7 Filter manager to prefer FFDShow for 264 and VC1 etc.

Installed Avisynth, configured FFDShow to use libavcodec for VC1 and then tried to open a VC1 file (progressive I would think since it comes directly from a commercial BD disc) using MeGui.

No joy - get an error saying Avisynth cannot open the AVS file - Make sure it's a valid avisynth script etc. The only avisynth script command I have is directshow(" "). The error is a divide by zero. Changing ffdshow setting for VC1 to WMV9 or Disabled makes no difference - same error.

I am running ffdshow vesion 3355 April 11 2010 and Haali version 1.10.120.15

Yet if I change the file to another BD that has been coded as H.264, it opens just fine.

Changing the Win7 filters from Microsoft to FFDShow and back makes no difference.

Opening the VC1 file in graphedt only shows one graph - that for the audio - no graph for the video.

I must be missing some filter or codec but can't think what else to look for so any hints really appreciated.

Thanks

Mux into MKV to make the Haali splitter output VC-1.

I can try that but am puzzled why on another Win7 machine I can just DS in avisynth and Megui and it works just fine on the same file.

In newer halli media splitter VC-1 in ts/m2ts has been disabled. I have no idea why!?! Solutions
a) install older haali 11/01/2009
or
b) remux to mkv

Yes I just found out you noted that in the Win7DSFilter thread earlier this year:thanks: I found Haali 1.92.42.1 and when I installed that it all works fine. Man that took me about 3 days to sort out including a complete reinstallation of Win7 on the machine!

I actually did try to remux to mkv but didn't manage that but anyway, directly opening the file in avisynth is the preferred solution for me.

Thanks
