Capture video with automatic file name

[qbism]

This is a quick little change that automatically generates a video filename, just like the way screenshot generates a filename. It works with JoeQuake and derivatives like Qrack, Fitzquake Mark V, and Super8. Any "capture_start" without an argument will get an automatic name.

The benefit? Bind a function key to capture_start and another one to capture_stop to quickly toggle video capture. Super cool when combined with Baker's demo rewind/fastforward/pause found in Mark V source.

Code: Select all

void Movie_Start_f (void)
{
    char   name[MAX_OSPATH], path[256]; //qbism jqavi was MAX_FILELENGTH

//////////////////////CUT+PASTE START/////////////////////////////////////////
    int     i;

 if (Cmd_Argc() != 2) //qbism - autogenerate file name if none is given.
    {
        Q_strcpy(name,"quake00.avi");

        for (i=0 ; i<=99 ; i++)
        {
            name[5] = i/10 + '0';
            name[6] = i%10 + '0';
            sprintf (path, "%s/%s", com_gamedir, name);
            if (Sys_FileTime(path) == -1)
                break;   // file doesn't exist
        }
        if (i==100)
        {
            Con_Printf ("Movie_Start_f: Too many AVI files in directory.\n");
            return;
        }
    }
    else  //read the arg
    {
        Q_strncpyz (name, Cmd_Argv(1), sizeof(name));
        COM_ForceExtension (name, ".avi");
    }
//////////////////////CUT+PASTE END/////////////////////////////////////////

    hack_ctr = capture_hack.value;
    Q_snprintfz (path, sizeof(path), "%s/%s", com_gamedir, name);
    if (!(moviefile = fopen(path, "wb")))
    {
        COM_CreatePath (path);
        if (!(moviefile = fopen(path, "wb")))
        {
            Con_Printf ("ERROR: Couldn't open %s\n", name);
            return;
        }
    }
    movie_is_capturing = Capture_Open (path);
}

I recently went into trouble because many engines limit themselves to 100 screenshots. Would be great if you could add at least one zero to the filename.

The engine I use (not public sadly) let's the user specify the demo name from variables. By default it uses the bsp filename, player name and datetime (might be my settings actually, I dont remember if I ever changed them). game/mod name might be a nice addition too. Anything that helps not to be in the "nameless" quake001.avi, quake042.avi and quake123.avi hell.

Would be great if you could add at least one zero to the filename.

Should be fairly easy. And adding a character would still be DOS compatible. (If it would be possible to vid cap in DOS.)
Not near my comp, but something like

Code: Select all

...
Q_strcpy(name,"quake000.avi");

        for (i=0 ; i<=999 ; i++)
        {
            name[5] = i/100 + '0';
            name[6] = i/10 + '0';
            name[7] = i%10 + '0';
            sprintf (path, "%s/%s", com_gamedir, name);
            if (Sys_FileTime(path) == -1)
                break;   // file doesn't exist
        }
        if (i==1000)
...

As far as the base name, should also be easy to tack on that additional info.
