FFDShow and yv12 \ yuy2 settings

I have been playing around with ffdshow + windvd filters to see is there any possibility for more quality.


This is one area I don't understand, maybe some of you guys could explain it for me \\ the rest of the forum.


What colour format does DVD come in.


When WinDVD itself is used it is possible to force YV12 colour mode. I cannot see a difference but maybe there is one?


I can't get the WinDVD Video filters to use YV12.


Looking at ffdshows Info section, it says now playing is YUY2 (uncompressed) and the output is YV12,adj.


Is the YUY2 what WinDVDs video filter is outputting to ffdshow?


I then changed ffdshows supported output colourspaces and managed to get it to say


now playing is YUY2 and output is YUY2. The video became very choppy then. So maybe a conversion to YV12 is needed and then onto RGB32.


Could somebody clear this up and explain what would be the most desirable settings for quality and speed.


PowerDVD uses YV12 by default (not sure about its filters) and WinDVD uses YUY2 (but can be forced to YV12 in the player, not the filters as far as I can see)
