And as usual in these cases, after several hours of experimentation and cursing, a solution of sorts presents itself just minutes after one admits defeat and asks for help.
This is not a real solution per se, but rather some information that might be useful:
The WCP DVD playback addon does not, it seems, like external screens on laptops. The fact that the laptop has multiple GPUs may or may not be relevant.
Literally every other piece of software or game I have ever tried have worked flawlessly whether on the internal screen or on any of my two external ones. But not WCP. If I want to see the DVD movies, I will have to make the internal laptop screen my primary, then launch Prophecy so it shows up on that screen an no other. Then I get to see Tom Wilson be an asshole and all is well. I'd much rather see him on my 27" screen, but oh well.
I'll continue experimenting; if anyone has any idea on how to make the vobs work on an external screen connected to a dual-gpu laptop I'd be grateful if they shared.
I know that @Pedro was looking into better playback options for WCP DVD video in the GL enhancements. I don't think this was completed but I may be wrong.
I just installed WC4 from GOG and I have and odd "problem".
First of I was supprised to find that GOG has the DVD version, thats good.
Now I run into the problem that I have an 21:9 screen. The video gets cropped while the gameplay stays 4:3. That is quite confusing as its normaly the other way around. Has anyone an idea how to fix that?
You don't lose any picture on a 16x9 or16x10 monitor. The aspect ratio of the picture is just slightly wider than your monitor would be at about a 2:1 ratio with black bars baked in (letter boxed). Having the video "touch the top" is problematic because there's no way to automatically zoom the picture to the height of your screen. Even if you did manage to have a way to auto detect the edge of the picture and zoom it so the top of the picture touched the top and bottom, that would actually end up cropping off the ends of the picture on a 16:9 monitor.Yah I bet that 21:9 wasn't around back then but then again to crop the videos at all is kinda odd to me. I could understand if they just cutoff the black bars but cutting until it fits is a bit to much. Also if they had gone with just filling up the hight not length of the screen that would be less of a problem.
Anyway deactivating the Mpeg2DecFilter.ax file stopped some text flickering I had with subtitles.
Also the mpeg2.dll seams to have something to do with it. I tried another mpeg2.dll I found online and it told me something was missing inside.
So I guess this is where the "patch" might be. Sadly I have no idea how to edit or even look into a dll file. Wordpad just gives you random signs.
The Dolby intro is 4:3 but the rest is with a letterbox but all files, at the least the GOG version files I randomly picked, are 704x480 or do you mean pixel aspect ratio?
All that makes me wonder if one could recode the entire stuff and on the way correct things. On the other hand its about 300 files and fankly I have better stuff to do (beside not beeing sure I could get it to work ingame). I think I will stick with how it is now. I mean I know the scenes and most of the time there are no heads cut off.
another weird WC4 issue. first i had the sound during FMVs too low issue. i tried adjusting the voume via the k-lite codec packs tweak utility, but it didn't make a difference, like not at all. i then downloaded the ac3 filter from this thread and set master volume to +20dB which fixed the sound issue, but now the video is weirdly cropped, like zoomed in and i can only see maybe a fourth of the actual video.
this game i tell you. didn't have nearly as much trouble with WC1-3, but WC4:
tried the dos version for dosbox built-in keymapper and windowed mode, but in that version i can't use the joystick, it just doesn't move anything (buttons work though and calibration as well).
then installed joy2key to remap buttons for the DVD version, because in the DVD version the joystick worked at least, but in the DVD version the sound and music often just get cut off, plus the issue with the cutscene volume and it's just a total mess.
thank you, but not necessary. restarted my PC and now it works. only issues remaining now are the finnicky sound in-flight and that sometimes joystick buttons do something when they absolutely should not do something (except for what i defined through joy2key).Do you have a super wide monitor? I had the same issue and had to manually edit it. I can send you the fixed version if it's the same issue, or point you at the code you need to play with if it's slightly different.
