ListGen gets the resolution out of the XML data generated by MAME. If the resolution of the png snapshots is different, it's possible that MAME changes the resolution on the fly. It happens with several games, there was a mini-discussion about it in this thread.

Actually..... even in windowed mode.... windows mame doesn't support "tweaked" resolutions (ie screen sizes that you normally wouldn't see windows suporting) and thus 90% of the resolutions supplied by the listdetails data are simply ignored when inputted into mame. They will be close, but not always the same.
Thus why I simply set them all to 320x240 and let mame figure out the rest..... i'm assured that the resulting video won't be larger than 320 pixels wide. You can do the same thing with smaller resolutions..
For an example of this simply type:
mame pacman -window -resolution 255x255x32
pacman will show up with the height being no greater than 255, but the aspect ratio of the game will not be ignored and thus the resulting window will not be square.
I thought you guys knew this.... it's mame 101 ;)
You can turn off aspect ratio enforcment of course... but what's the point if mame does all the work for you?
Popcorrin:
Howard, why do the png's and the resulting video have a totally different aspect ratio than what mame displays while the game is being played? The aspect ratio on the videos is proportional to the resolution rather than your standard 4/3 aspect ratio.
Howard_Casto:
well... afaik when mame takes a screenshot, it just dumps the video buffer.... snapshots will always be the same size regardless of what resolution you are in when they are taken. However this isn't the issue here.
I guess the real question is... is mmm sending vdub the actual resolution of the window, or is it just going by the "resolution" flags you send mame through the command line. Because as I've pointed out.... the resolution flags essentially have no bearing on actual output. It would make sense to me at least, to have the video the same size as the window you had mame in when you captured the thing. Makes for wysiwyg user-friendlyness

Vdub uses the resolution of the pngs. It needs the pngs to be all the same size, which is the cause of the problems we had with resolution-switching games.
I suppose we can remove the -resolution thing. I thought it was important at the time to get the window to be at the same resolution that the original game used, to get the wysiwyg effect.
