megui crashes when opening files

[fib0by]

I've been using megui for a long time with excellent results until recently. Now it crashes whenever I attempt to open .avs or .mkv files.
I haven't installed any codecs recently. The crashes seem to have started to occur after autoupdating megui to version 3012

The Vista error thing says:

what does your avs look like ? what does your mkv contain as streams ? which encoder did you try ?

DirectShowSource("C:\blah-blah-blah\video.mkv", fps=29.970, audio=false)
AssumeTFF()
#deinterlace
#crop
#resize
#denoise

.mkv has only one track, MPEG2 HD 30fps interlaced, no sound, extracted with eac3to from an .mpg file captured from cable TV with MythTV.

I am trying to convert it to h264 using x264, using the Standalone AVC-HD preset, 3696 kbps, interlaced.

megui crashes when opening the .avs
If I go to File / Open and open the .mkv directly, again it crashes.

I am using ffdshow as a codec, just like I did for a long time before. libavcodec is the decoder enabled for MPEG2.

Funny thing is, this exact same .avs file worked before. I am trying to re-encode it because I made a mistake and encoded it with too high bitrate. Now megui won't even start encoding. :(

As far as I can tell, this thing just stopped working today and I can't figure out why.

open the .avs in a directshow media player and report back.

open the .avs in a directshow media player and report back.

Win Media Player crashes in a very similar way.

OK, I see now. I guess I'll have to reinstall Matroska, ffdshow, or something like that.

Uninstalled / reinstalled Haali Media Splitter and ffdshow in the most detail-oriented way possible:
- uninstall both apps
- reboot
- install Haali
- reboot
- install ffdshow
- reboot

MeGUI still crashes when opening the file. I go to File / Open, select the file and click Open. BANG! MeGUI is dead.

However, Windows Media Player does NOT crash when opening this file. It plays the file just fine.

The file is an .mkv created with eac3to, extracted from some other source. It contains a single HD MPEG2 track (1080p) and nothing else.

ffdshow is set to decode MPEG2 files via libmpeg2. Merit is default. Multiple ffdshow instances: only one - check all filters in graph. Don't use ffdshow in: (default list).
So I guess those are the default settings.

I am using latest versions of everything:
- MeGUI 0.3.1.1005
- eac3to 2.87
- Haali 1.8.122.18
- ffdshow rev2527_20081219
- Windows Vista will all updates applied

MeGUI used to work just fine on this machine until recently. The only thing I can think of is that I installed Office 2007 meanwhile. Maybe it's a coincidence, as I don't see how Office could interfere with playing mkv/mpeg2 files.

I have no idea what to do now. Any suggestions please?

Try changing ffdshow to decode mpeg2 via libavcodec instead.

Edit: Sorry I noticed you already tried that before you reinstalled everything.

You can try a newer build of ffdshow from http://www.xvidvideo.ru/content/category/1/4/5/

Uninstall Groove (if present)?

[Sharktooth]

if you're on vista and you installed office 2007, then groove is the problem...

[fib0by]

Aaaaarghhhh $@%&*^@@!!!!!!!

That did it. Stupid Groove. :mad: Very very annoying.

I haven't tried an actual encode yet, but now MeGUI can open the file without crashing, the preview window comes up and the AVS script is generated.

Is that an AviSynth issue actually? Not MeGUI per se?

[Sharktooth]

nope... it's some sort of incompatibility between microsoft products (groove and something in .net framwork 2.0).
