The next two tests will look exactly the same
as the YUY2 test except they will test decoding in YV12 and then RGB32
colorspaces. They should appear just like this YUY2 image except they
will say "YV12 Test" and "RGB32 Test" respectively. If any of the
outputs don't look the way they should then read the troubleshooting
If, however, everything is working fine you can move on to learning
about some of these programs.
Troubleshooting the Tests
The way the installer is written should mean that there should be no
problem whatsoever in the tests, but it is possible that problems could
occur. Read through the descriptions and see if there is anything that
solves your particular problem. If not, please report the error in the
Video Software Forum (a screenshot may be useful if it's a visible
problem) and hopefully someone will be able to help you.
1) A different version of Avisynth is being reported than the
one I tried to install!
This should be particularly noticeable if
the Version test reports 1.x or 2.0x version of Avisynth. You should
look in both your Windows (or WINNT) "System" and "System 32" folders
for avisynth.dll and delete them - you may even want to search your C
directory for this file too. After you have cleaned this up, go to the
AMVapp/Installed Files folder and re-run the Avisynth installer. Try
the test again and see if the version has changed.
2) I get an Avisynth error saying "There is no such command:
This means that there has been a problem during the
avisynth filters installation. Go to the AMVapp/Installed Files
directory and try installing the Avisynth filters again. Look in the
installation folder to see if the filters are actually installing. The
one you want installed is "DGDecode.dll"
3) I get an "Unrecognized Exception" error.
Oh dear - I
thought we'd seen the last of these. This error appears when either the
avisynth or DGDecode.dll finds a problem with processing the source
but it's a problem that hasn't had an error code written for it. This
can mean anything and if it is happening on the AppTests then it's not
good. Make sure the Version test is correct and the Avisynth Filters
have been installed correctly. Also double-check to see if your
Avisynth 'Plugins' directory - there should be a file called
DGDecode.dll and NO files called mpeg2dec.dll or mpeg2dec3.dll.
4) I get a "Cannot playback file - format is not supported"
This means that Avisynth has not been installed or has been
installed incorrectly. Try installing again, see if the avisynth
installer gives you any errors. You will probably need administrator access
to install avisynth, so check that you do.
