Problem with win7 64bit, avs32bit, qtinput and mencoder

[hanfrunz]

Hello,
i have a pc with:

windows7 professional 64bit
32bit avisynth
32bit mencoder
qtinput 0.8alpha avisynth-plugin

I can play my script with mediaplayer and virtual dub, but if i use mencoder i get an "can't initialize quicktime" error. I think it's some weired windows7 32/64 bit problem... If i use the same combination of programs on a win xp 32bit machine everything is fine. Any ideas?

regards,
Hanfrunz

Stupid question: Is Quicktime installed on the computer?

[hanfrunz]

Yes it is. You can play the .avs fine in all other tools like mediaplayer or vdub. But the combo mencoder+avs+qtinput doesn't work.

Hrrm... you ARE using a 32 bit version of mencoder, right? I'm not sure a 64 bit version exists for windows, but maybe? /shrug

I use the same mencoder version i used under xp-32bit (i just copied the folder)

A few ideas

1) Is UAC disabled? If not, kill it!
2) What format is your source video? It *shouldn't* matter, but I'm curious... ProRes is the only common thing that won't work either directly via ffms2 or by remuxing and using Directshow or something.
3) Any other apps on this system that could possibly interfere? Tried a clean install of Windows?
4) Tried other builds of MEncoder?
5) Tried using something like avs2yuv as an intermediary?
6) Tried other versions of AviSynth? I'd go back to 2.5.8 vanilla if you're having any weirdness. Try 2.6 MT and 2.5.8 MT as well...

On that note, why MEncoder? If other tools work, it doesn't look good for MEncoder :)

I'd imagine you're using some special feature that's either not easy / impossible to do with other encoders?

Perhaps you should build a new workflow entirely?

Hi Derek,

Thanks for your tips. I'll check them.
I use mencoder only because it's a commandline encoder and can take avs as input. It's part of a batch file that creates a avisynthscript (quick and dirty deinterlace + TC burn in) and then encodes it to a simple mpeg4 (xvid) avi file.

If none of the suggestions worked and you do not have a particular preference for mencoder then ffmpeg is also a command line encoder that can take avs as input and encode to xvid

Command line would be something similar to this

"path\to\ffmpeg.exe" -i "path\to\input.avs" -f avi -vcodec libxvid
-vtag XVID -s 704x384 -aspect 16:9 -maxrate 1800k
-b 1500k -qmin 3 -qmax 5 -bufsize 4096 -mbd 2 -bf 2 -flags
+4mv -trellis -aic -cmp 2 -subcmp 2 -g 300 -acodec libmp3lame
-ar 48000 -ab 128k -ac 2 "path\to\output.avi"
