Avisynth doesn't see Lagarith codec... but it's installed

[Darryl In Canada]

I captured two 8mm tapes with the same hardware, software, and settings. I used the LAGS codec. When I drop this AVI files into GSpot, they are identical and the LAGS codec is in green with the status "Codec(s) are installed". The only difference in GSpot between the two files is that in file#1, the AVID box is not on(?) and file#2, the AVID box is on(?).

Here's the symptom: when I drop my AVS file into VirtualDub64, I get an error.

Here is the AVS code:
AviSource("video file 1.avi")
QTGMC( Preset="Medium")
SelectEven()

Here is the error:
Avisynth open failure:
AVISource: couldn't locate a decompressor for fourcc LAGS


I had previously downloaded Lagarith from https://www.videohelp.com/software/Lagarith-Lossless-Video-Codec and installed it.

Here is what GSpot says in the details about Lagarith Lossless Codec:

- - Type VFW

Do both avi's have the issue with AVISource ? Do they play ok in a media player like MPCHC ?

What does vdub2 x64 say with file=>fiile information , when you open fiile 1 or 2 avi directly in vdub2 (not through avs script)?

As a workaround for now, you can use ffms2 or lsmash as the source filter

eg.

FFVideoSource("video file 1.avi")

or

LWLibavVideoSource("video file 1.avi")

Make sure you have the right version as in 64 or 32 bit.

I'm having the same issue. Here's my script (AVISynth+ 64bit):

clip1=AVISource("H:\Videohelp\DMS\test trimmed.avi")
clip2=AVISource("H:\Videohelp\DMS\iodata trimmed.avi")
StackHorizontal(clip1.subtitle("Dazzle"), clip2.subtitle("GV-USB2"))

Both open OK in MPC (BE), both open OK in VDub2 64, and as far as I know, the LAGS installer does both 32 and 64.

I'd be grateful for any ideas.

In the meantime, I'll do the different source calls PDR referred-to.

Thanks!

Open your avi in fourcc changer to see if LAGS is displayed.
If not, set it and apply the change. Backup your avi first.

[Alwyn]

Thanks ProWo, LAGS is already set, but I did reset both; no go. Still won't open them.

The two AVIs I have are trimmed (Direct Stream Copy) of DMS's files in this topic:

The "test" avi is further back.

Vdub2 comes with lagarith preinstalled as vdf file and sometimes conflicts with the lagarith codec trough install. Try in vdub 2 fastrecompress from lagarith to lagarith but select in compression the second one in the list lags try that file in avisynth with avisource it should work or if vdub 1 is oppening it and then from there fastrecompress ( not direct copy) because it is stuck in the vdub lags codec and nor avisynth nor any other editor is unable to open it but it should play in vlc

Retry with lags (lowercase).

[Selur]

Is the decoder listed as VDIC.LAGS in the registry under:
"HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft \Windows NT\CurrentVersion\Drivers32"
and/or:
"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32"
?

[davexnet]

As well as Selur's details, a copy of lagarith.dll should be in c:\windows\system32 and c:\windows\sysWOW64\

[Alwyn]

No joy.

Is the decoder listed as VDIC.LAGS in the registry under:

Yes (VIDC).

Yes.

This was it. I do have two LAGS in VDub's codec list. But I didn't create the AVI in the first place. It seems that @DMS, in the other topic, created the LAGS AVI with the VDub LAGS and not the real LAGS.

Is there a way of removing the VDub2 LAGS?

Probably just remove the associated vdplugin files from the vdub2 plugin folders

The file I created with the built in LAGS opened OK in avisource

[Alwyn]

Thanks Dave, did that, it's still there! Must be in the Registry somewhere...

[davexnet]

It works for me. Only the installed version is visible

[Alwyn]

Mine's still in the list but it fails on "Save Video..." because, I assume, I moved it out, so I can't use it.

That will force me to use the proper, external one lower down. Bit of a nuisance for newbys though.
