Wrong YUY2 Codec causes colourspace errors on AVISynth scripts feeding TMPGEnc

Well, your fix does work :) But adding ConvertToRGB works too. There is no difference in speed since it will be converted to RGB in both cases, either by Avisynth or by HuffYuv.

This DLL comes with DirectX 8.1. greetz, Uli

This is interesting. A couple of days ago I started to get errors when viewing avi or ogm files. bsplayer or zoomplayer (and dvd2avi for that matter) informed me that my hardware was unable to process yuv and I should switch to rgb. I hadn't seen this problem before. It just so happens that I have recently installed DirectX8.1. I didn't think this caused any issues but then my problems started to appear a couple of days ago. Maybe there is a link? I am a little stuck with fixing my problem so any advise/guidance from the experts would be most appreciated. Should I go back to previous Directx version? Or mess around in the registry? Thanks in advance. Gazza

I tried changing msyuv.dll to huffyuv.dll as suggested but still got the same problem. There must be something else that is impacting. Anyone got any ideas on what I could try next? I'm a little in-experianced in this area. Thanks in advance Gazza

@Gazza I haven't tried changing the registry but I tried adding the command ConvertToRGB() and it worked... Another way I've just found out is using CCE instead of TMPGEnc...

To all who provided suggestions, etc. Thanks for your help and advice but unfortunately my problem didn't go away. So I am going to rebuild (a long time overdue) and return back to normality. Again, thanks for your suggestions. Gazza

Hm, I got inspired by this, and as we're all lazy you might wanna checkout the attachment to this post :) (Ok, until the mod approves the attachment: it's an easy installer which comes along with huffyuv.dll to make it _really_ easy..) Regards, Koepi EDIT: had to upload the attachment again (hopefully it really overwrites the old one) as the old one didn't work properly. This installer does in fact install huffyuv (and can properly uninstall it again :) ) and registers all colourspaces registered to msyuv.dll to huffyuv.dll. Since I use that some of my capturing problems are gone, too! :)

YUV is a colorspace. YUY2 & YV12 (& UYVY & a host of other nasty incompatible formats) are byte formats for storing 16-bit YUV pixels subsampled in various ways.

In my previous message I said I was going to re-build and in effect remove Directx8.1. However, I got in touch with the manufacturer of my computer. It turns out that my problems (ie unable to convert yuv color space during replay of avi's) was in fact due to having M$ Netmeeting active on my desktop. Once this was de-activated everything has returned to normal. I'm posting this as a hint if others hit on the same frustrating problems I have in the last couple of weeks. Gazza
