C++ :: How To Get The Current Video Mode In Console
Apr 2, 2014
I've been wondering if there's a function or procedure used to know the current video mode. An example of how this was done in Pascal:
function VideoMode : integer;
begin
if (lastmode = BW40) or (lastmode = BW80)
VideoMode := 40
else
VideoMode := 80;
end;
I've been told "conio.h" has a lastmode function, but it doesn't seem to be supported in Dev-C++ and Visual Studio C++. Is there a Windows function to know the number of columns in the current video mode?
I'm currently stuck whit a problem. I would like to access video memory of the console(Yes, only the black box) in C. I know how to do it in turbo pascal :
Var video:array[0..4000] of char absolute $B800:0000;
But i don't know the numbers in C. I've searched for the numbers of the memory in C but i can't find it.
I have been working with video files and my task is open a video file, get it copied into another file and then changing into binary format. after getting few bits inverted, changing back it into ascii formats. Original video contains normal and extended ascii codes. Unfortunately, i got stuck at first step, whole video file is not being copied. i have written a piece of code that copies the whole word/ any text file but the video file is not fully copied as just 5KB out of 119,659 KB are copied.
I have loads of movies on DVD and they are all on my media server, but the media server doesn't actually allow streaming to be done, the movies are just stored in a folder on the desktop.
My goal would be able to host all my movies on my LAN server, then build an application to run on a windows based PC at home, not over the Internet just over LAN. For example, say the server I have at home had all the movies in a folder on the desktop, then when I start the client on another PC or laptop in my house, I could view all the movies, choose which one and then stream it to that client PC. I am using C#.NET WPF visual studio.
Maybe I could use something like VLC player to play the movies but I would want to build an client application to view the movies and search for them on the server where the movies are stored. Also I know there are other media streaming programs out there but I want to develop my own one for my uses.
I am using DirectShow to play/pause/stop a video file. I am having a slider control which increments with the playing video. I have done some calculation to find the exact step to forward or backward the video.
On dragging the slider to any position, video forwards/backwards to the new position, but slider doesn't get increment. Say I drag the slider from 10 to 50, video goes to the new position, but on releasing the capture slider again jumps back to the previous position from where it was dragged.
I would like to know in which way is the best to make ActiveX control for video. ActiveX control will need at least show picture and be able to go back in past, change resulation of picture and similar. How complex it is to do something like that? Is MFC best way to make it? Is there somewhere similar code?
I have code (found long time ago, ~2001) to make videos from OpenGL rendering in my view class. In my OnDraw() function I call the function SaveAsAvi(). This works as intended until I have 255 frames in the movie I am trying to make. After that, Windows Media Player claims it cannot play the file. VirtualDub claims the avi contains Palette Changes and shows the correct number of frames (>255) but all frames past 255 are the same and equal to the last frame.
Memory overflow? Need to free m_pixels sometime somewhere?
Code: void C***View::SaveAsAvi() { C***Doc* pDoc = GetDocument(); if (pDoc->m_avi_status == -1)// initialize AVI stuff { KillTimer(1); // allocate space for the pixel info
I am working on a video game that is based on a tutorial I found online and I ran into an issue associated with accessing an object's method inside another class object's function without making the object global which seems bad.
Here is basically how the tutorial set things up in the game: The game has a base class called GameObject then there are other child classes that inherit from this class. The GameObject class has all the basic information an object would have that needs rendered on the screen (x/y position, size of bitmap, bitmap, whether or not it is collidable, etc).
One of the child classes SpaceShip, which is the player so it has attributes and methods associated with managing # of lives and points scored.
There are other child classes of GameObjects in the game that need to take life and add points from the SpaceShip object if they collide with the spaceship or other objects.
In the collision handling routine I basically call a function "void Collided(int objectID)" when a game object collides with another. Within the Collided() routine, there is logic that executes code or other functions based on the objectID it collided with. Some of the collisions require taking life from the spaceship or adding points. The way this was accomplished in the tutorial was with function pointers (see Bullet class constructor and collided method for example). Is this really the best way to handle this sort of thing? It seems like there has to be a simpler way than to keep referencing function pointers in any new class I want to add to the game. I realized this when I went to add a method for the spaceship to fire bullets rather than inside my game class.
Basically i'm willing to create an application which could share Video,Mp3 Over the internet to my friends.
For suppose I'm hosting file on my PC, and i want to share "D" Drive to my friends but they aren't connected to my network locally. i want to share movies over the internet using a host and client application in c#.net.
the purpose of this application is very clear that that i want to share movies over the internet and they have to be able to watch movies on their PCs Except running my PC remotely.
I try to play a video I i don't know how.. I searched and i found some tips and articles, but all of it if about Windows Media Player. It's fine, but i need to play something lika an intro an i don't wanna show all that buttons of WMP.. I tried to hide it but no change.
I use ffmpeg codes in my C++ app and would like to control the bit_rate parameter for VIDEO there. I tried to change its value in work (via ost->st->codec->bit_rate = 150000), but ffmpeg did not wish to change it.
I am using DirectShow to Play / Pause / Stop and Capture Video files. But Capturing and playing of video files is simple. I want to Implement HD Video recording in my project.
how to Implement HD Video Capturing using DirectShow.?
Or Apart from DirectShow, is there any other method to Implement HD Video recording in MFC.
I have a code which is a set of rgb frames to be displayed at 25 fps to make it look like a video. While I createWindow invalidate and update it based on a timer, the video plays fine, but the buttons of Play, Pause etc hangs during the time video is playing.?
I've been trying for over an hour to think of the logic to find the mode of an array.I left out code for initializing the arrays, but all the values in the array are between 0-9. Check out my code below.
Code:
int mode( int array[], int size ) { int i; int count; int max = 0; int num = 0; int mode;
How do you find a mode in array? This is what i got so far. I put this after i sort the array
for (int index = 0; index < size2; index ++) { //count[mode[index] - 1]++; if (mode[index] == mode[index + 1]) // compare the first to sec array { again++; cout <<"This is number " << again << endl; } }
