I tried to set up a VM running on centos7, my host run on windows 10. After I add the guest additions, my mouse still doesn't work properly : if you look at the image (https://imgur.com/a/zKeMRvT), the mouse work properly below the red line, and won't work on the rest of the screen. I found nothing related to that problem on Internet, so I'd be glad if you had any idea or advice.
You have to press the [CTRL] key on the right hand side of the keyboard.
Then the mouse gets release back to you.
I am using multiple monitors on my PC. One of them is a TV. When I launch my application on my regular monitors, the application gets scaled properly.
However, when I run the application in fullscreen on my TV, the resolution will be too large and the output shows partially on another screen (see the blue colored output in my screenshot).
The TV is connected via HDMI and uses the same resolution as the other screens (1920x1080). It seems to be a software issue, because the output is partially visible on another screen.
I am using the following code to toggle fullscreen mode:
SDL_SetWindowFullscreen( m_Window, SDL_WINDOW_FULLSCREEN );
Any ideas on how to solve this issue?
UPDATE
When I make the TV my main display in Windows, it seems to fit properly on the TV. However, it still shows partially on the other screen (but this time it shows twice) and the mouse positioning is incorrect on the TV. Maybe the resolution is changed differently?
UPDATE 2
Windows 10 allows font sizes to be changed on a monitor. This is why my resolution detection in SDL2 identified a different resolution for my TV. Now I need to find a way to work around this.
I'm trying to use SwisTrack software.
http://en.wikibooks.org/wiki/SwisTrack
I've installed using windows installer in 2 computers.
in both computers I have the same problem.
also tried with different usb cameras.
when I choose Input from usb camera - the camera detected, and the light on the camera turned on (so the software can see the camera and connect to it) - but the frames I got is totally black.
is anyone can help? is there someone here familiar with SwisTrack?
Thanks
It works for me. Just image outputs flipped.
Did you select source for output window? (see click on yellow caption on window header) :
With a single monitor my program works in both windowed and full screen mode (using any resolution chosen from EnumAdapterModes), but when I plug in my second monitor (running the same code) I can create a full screen device at any resolution from EnumAdapterModes, but only at the native resolution (1600 x 900) does it display the scene, otherwise the screen is just black among other problems listed below.
What I've discovered so far:
This problem does not occur in windowed or multihead mode
I can still render to a texture (I had to switch modes to display it though)
All function calls return success codes (including TestCooperativeLevel)
If I try to draw to the back buffer using Clear or the DrawPrimitive functions or call Present (which still leaves a black screen), than calls to GetRenderTargetData fail and attempting to lock a volume texture will return different slice pitches at sub levels
Commercial games that use Direct3D9 (Portal) don't have any problem switching between resolutions with my second monitor plugged in so there must be a solution
The problem seems to be related to the back buffer created by the Direct3D9 run time but the only solution I can come up with is to force multihead mode on devices with multiple monitors, any ideas?
Question that seems to have the same problem but lacks a solution: How do I render a fullscreen frame with a different resolution than my display?
Finally figured it out, seems to be a driver bug in Windows Vista and later and using Direct3D9Ex fixed the problem.
I didn't want to use Direct3D9Ex because it was only introduced on Windows Vista and I wanted to support Windows XP as a minimum, but MSDN has some sample code on how to support both so it's all good.
for a simple demo program I am using the SDL library to play a mpeg movie file.
Unfortunately the demo app should be executed on one of our windows 7 servers and it should be looked at remotely.
The problem is, that when I connect via RDP to the server the SDL window stays black - although the movie becomes played (I hear the sound).
I guess this has something to do with the rendering device of OpenGL or DirectDraw when accessing via remote desktop. Does anyone know which settings I should use for setting up the SDL window so it works via RDP also?
When I play the movie with the windows media player the movie becomes displayed correctly - what kind of device uses the media player?
The problem is probably that SDL is rendering directly to video memory (or some sort of DirectDraw surface), but the RDP program is only able to retrieve what's in system memory.
If this is the case, there's a few things you can try. First is a different RDP program that has the ability to grab from DirectDraw or video memory. The other thing is when you call SDL_SetVideoMode() use the SDL_SWSURFACE flag. This will render to system memory where as SDL_HWSURFACE will render to video memory.
