SOME OF THESE FILES MAY BE OS SPECIFIC, I.E IT MAY ONLY RUN ON WINDOWS 95, 98 , NT, 2000, OR WIN7 32BIT
I AM ALSO NOT RESPONSIBLE FOR ANY LOSSES YOU MAY SUFFER FROM USING THESE CODECS, USE SANDBOXXIE TO BE SAFE

You can use [VirtualDub](https://www.virtualdub.org/)/[VirtualDubMod](https://managedway.dl.sourceforge.net/project/virtualdubmod/VirtualDubMod/VirtualDubMod%201.5.10.2/VirtualDubMod_1_5_10_2_All_inclusive.zip)/[VirtualDub2](http://virtualdub2.com/) (Try to use 32bit as much as you can), or [MEncoder/MPlayer](https://mplayerhq.hu/design7/news.html) to Encode and View the avi's encoded with these codecs.

If VDub doesn't fit your fancy for some reason (Sometimes when you install a codec driver, it wont show up in VDub) you can use MEncoders vfw options like so:

```
mencoder input.mp4 -ovc vfw -xvfwopts codec="/Users/Username/Downloads/igcodec.dll" -nosound -o output.avi
mencoder input.mp4 -ovc vfw -xvfwopts codec="/Users/Username/Downloads/OldAndObscureCodecs/Rududu.f i l e s/rududu.dll":compdata=dialog -o output.avi
ffmpeg -i input.mp4 -c:v huffyuv -s 1920x1080 -f avi -t 5 -an - | mencoder32 - -ovc vfw -xvfwopts codec="/Users/Username/Desktop/OldAndObscureCodecs/Loss-Less Codec Library(AVImszh + AVIzlib)/LCL223/avizlib.dll" -o output.avi
```

You MUST use forward slashes in your .dll path for some reason like I did above, this does not work: `-xvfwopts codec="C:\Users\Username\CodecDirectory\igcodec100\igcodec.dll"`

If you have trouble loading a codec with an error message like "Can't open library:" or "ICOpen failed! unknown codec / wrong parameters?", try moving the .dll to your Desktop or something and try again. Sometimes whitespace or certain special characters appear to mess with MEncoder.
