Suddenly can't find UYVY?

[Trixter]

I've got a serious problem that is going to make me slip a deadline until I can figure it out, and I'm hoping someone can help me. I have a script that joins several .AVI files together, very simple stuff:


AVISource("megademo.avi") + \
AVISource("MentalHangover.avi") + \
AVISource("Enigma.avi")


...etc. I encode this .avs with CCE. Up until last weekend, it worked fine... but today I try it and CCE now shows the avisynth output to be "AVISource: couldn't locate a decompressor for fourcc UYVY".

I didn't change anything! I SWEAR I didn't install any codecs. About the only thing that might have done something is I installed Vegas 6.0, but I've restored to a system checkpoint before that and the problem is still here.

What happened? How can I solve this? All searches for "UYVY" on doom9 and google are telling me to install HuffYUV but it's already installed... help?

One of you AVI's has a strange fourCCin the header. But you can force AviSynth to use another compressor than suggested in the FourCC. I dont know wich one would work best though, you'll have to find out wich "fourCC" will work with your files (fourCC is a kind of code that indicates wich decompressor to use).

Look here for the manual: http://www.avisynth.org/AviSource

For example, this might work:


AVISource("megademo.avi", fourCC="XVID") + \
AVISource("MentalHangover.avi", fourCC="XVID") + \
AVISource("Enigma.avi", fourCC="XVID")


The other solution is to simply change the fourCC of the AVI that has the strange FourCC ;)

No, they all have the same fourcc, and up until last week they all worked correctly.

However, I'm okay with trying a different decompressor for them as per you suggestion... what other codecs will handle the decompression of "UYVY" (other than XVID)? Are there any particularly popular or recommended ones?

FFDShow, when "Raw Formats" is selected for decoding. (In vfw panel when using with avisynth.)

I understood all of that up until you wrote "in vfw panel". How do I access that?

Use run>regedit and take a peak at: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32]

What is your listing uyvy? Mine is: "vidc.uyvy"="msyuv.dll"

If I remember correctly, I used to change the vidc.yuy2 to huffy.dll when using CCE. I don't remember any problems with vidc.uyvy

Theses things get overwritten sometime.

Oh, sorry, missed that. ffdshow has three shorcuts: video options, audio options, and vfw options; the vfw and video aren't linked yet so you have to set them separately.

Mine is also msyuv.dll, but I am using CCE so the next time I can't get past this bug (I found a workaround) I'll do that. Thanks for the advice!
