Avisynth 2.07 won't decompress AVI/MPEG

[Scoobydeux]

I am new to AVISynth, I have used primarily VFAPI up to now. I am trying to get AVIsynth 2.07 to work, and have had some problems...

I cannot get a simple "AviSource("G:\test.avi")" script to frameserve, it says "unable to decompress frame 1" when I try it in MPlayer. I also cannot get "MPEG2DEC.dll" to work, I load it, then when I select the source I get the error "Unrecognized Exception in Line 2".

I HAVE been able to create a file using:

blankclip(345600,720,480)
ResampleAudio(44100)

To give me a 4-hour blank clip, but for frameserving it is a no go. I have checked all the old AVISynth versions are gone, I have re-run the installation, I have turned off VDub, what else can I do to make AVISynth frameserve?

Frustrated noob @ avisynth...

I had the same problem!!

The only one solution for me it's to UNINSTALL this version and come back to 2.06 waiting for bug fixes :(

Can you open this avi in WMP, how did you make it (what codec)?

I also cannot get "MPEG2DEC.dll" to work, I load it, then when I select the source I get the error "Unrecognized Exception in Line 2".
Are you using dvd2avi 1.76? If you are using 1.77.something change it to the older version 1.76.

Ok, good. AviSynth is installed properly.

Thanks for your reply! I appreciate your help......

I tried several AVI's from various sources (none that I created, I guess I could try that to make sure a stable codec is used) but they ALL played correctly in WMP prior to my trying them with avisynth.

You are CORRECT, I was using DVD2AVI 1.77.3. I'll go dig up my older version and reinstall that....

Could you open the avi and look at the "file information" to see what codec is used.

[Scoobydeux]

The first one was listed as:

Indeo® video 5.10 Decompression Filter

I added this to the buglist in sourceforge. What you can do is convert them to Huffyuv in VirtualDub and frameserve using AviSynth with the huffyuv-avi.

Reverting to 1.76 fixed the problems.... I also converted those other avi's with v-dub, and they worked.... I guess I had 2 different problems altogether.

Thanks for the help! Works like a champ now.:p

try with AiSource("G:\test.avi", false)
You won't make a search into de video but you can encode from the beginning to the end.
