automating load subtitle file in windows xp

[manit]

Hi ,

I recently wrote c program which autoloads subtitle file (srt type) , if only one or none found else asks user to select appropriate file from list .

Now I plan to write the same using autoit as it gives a gui look unlike DOS of c program binary.

First I did

I added an entry in registry

key : HKEY_CLASSES_ROOT\*\shell\autoload video with subtitles\command

default string : c:\turboc3\source\pass.exe %1

BTW my c code is

expandcollapse popup

//printf("\nflag line 1"); used while debugging
#include<string.h> // for strcat,strcpy,strlen,memicmp,strrev
#include<stdio.h> // for fgets,fopen,fprintf,fclose
#include<stdlib.h> // for atoi,system
#include<conio.h> //for clrscr
//(3)currently we are using g:\log,list,a.bat files
char name[128],finalsf[128],sf[20][128],fp[128];//sf=subtitle file,name=only video file name
int sfnumber;//number of subtitle files found
 
int check(char d[128])
{ int len,cr;//cr=compare-result
char bkup[128];
len=strlen(d);
d[len-1]=0;//because last character in string received is \n then 0
strcpy(bkup,d);
strrev(d);
cr = memicmp(d, "trs", 3);
if (cr==0)
{ //printf("\n%d:%s is an srt file",len,bkup);
strcpy(sf[sfnumber],bkup);
return 1;
}
else
{ //printf("\n%s!=trs",d);
return 0;
}
}
 
int findsubtitlefile()
{ FILE *fr,*log;//fr=read g:\\list.txt,log=write to g:\\log.txt
char fn[128];//fn=file name
log=fopen("c:\\asf\\log.txt","a");
if(log==NULL)
printf ("\nCould not append g:\\log.txt in function findsubtitlefile");
fr=fopen("c:\\asf\\list.txt","r");
if(fr==NULL)
printf("\ncould not read g:\\list.txt");
fprintf(log,"\nwe have to search srt in following \"name-length:file-name\" pairs \n");
while ( fgets ( fn, 127, fr ) != NULL )
{ fprintf(log,"%d:%s\n",strlen(fn),fn);
if(check(fn))
{ fprintf(log,"found subtitle file : %s\n",strrev(fn));
sfnumber++;
}
}
fclose(fr);
fclose(log);
if(sfnumber>0)
return 1;
else
return 0;
}
void letuserdecide()
{ int i;
printf("\nPLEASE CHOOSE SUBTITLE FILE");
for(i=0;i<sfnumber;i++)
printf("\n%d)%s",i+1,sf[i]);
printf("\nEnter option:");
scanf("%d",&i);
strcpy(finalsf,sf[i-1]);
}
 
void main(int argc,char *argv[])
{ FILE *log,*action;
int i,j,len;
char dir[120],command[512];
clrscr();
log=fopen("c:\\asf\\log.txt","w");
if(log==NULL)
printf ("\nCould not open g:\\log.txt for writing ");
// fp=full path
for(i=1;i<argc;i++)
{
strcat(fp,argv[i]);
strcat(fp," ");//here sprintf will not work because we are appending to fp in each loop
}
fp[strlen(fp)-1]=0;
fprintf(log,"full path=%s\nnumber of words=%d",fp,argc-1);
//copying directory name to 'dir' variable
len=strlen(fp);
i=strlen(fp)-1;
while(fp[i]!='\\')
i=i-1;
for(j=0;j<i;j++)
dir[j]=fp[j];
dir[j]=0;
fprintf(log,"\ndirectory is %s",dir);
//copying file name to 'name' variable
for(j=0,i++;i<len;i++,j++)
name[j]=fp[i];
//printf("\nfile name:%s",name);
fprintf(log,"\nfile name : %s",name);
//executing 'dir' command to output all items in current folder to g:\list.txt
sprintf(command,"ls -1 \"%s\" > g:\\list.txt",dir);
system(command);
fprintf(log,"\nwe have executed : %s",command);
fclose(log);
command[0]=0;
//let us find the subtitle file
if (findsubtitlefile())
{ //run the file with subtitle
if(sfnumber>1)
letuserdecide();
else
strcpy(finalsf,sf[0]);
sprintf(command,"\nk -subfont-text-scale 3 -fs -vf screenshot,expand=0:-40:0:0 \"%s\" -sub \"%s\\%s\"",fp,dir,finalsf);
}
else
{ //run file without subtitle
sprintf(command,"\nk -fs \"%s\"",fp);
}
//printf("\nwe will run %s",command);
action=fopen("c:\\asf\\a.bat","w");
if(action==NULL)
printf("\nCould not open g:\\a.bat to write kovensky play command");
fputs(command,action);
fclose(action);
system("cmd /c g:\\a.bat");
//getchar(); while debugging to read output before exiting
}

$CmdLine will be useful to get file name passed

You didn't ask any questions, so I assume you are looking for some kind of starting point. Here's something to think about:

expandcollapse popup

#include <ButtonConstants.au3>
#include <ComboConstants.au3>
#include <GUIConstantsEx.au3>
#include <StaticConstants.au3>
#include <WindowsConstants.au3>
$fileCount = 0
$subtitleFile = FileFindFirstFile ("*.srt")

If $subtitleFile = 1 Then
    Dim $subtitleList[1]
    While 1
        $file = FileFindNextFile($subtitleFile)
        If @error Then
            ExitLoop
        Else
            ReDim $subtitleList[$fileCount + 1]
            $subtitleList[$fileCount] = $file
            $fileCount += 1
        EndIf
    WEnd

    FileClose($subtitleFile)
EndIf

If UBound($subtitleList) > 1 Then

    $Form1 = GUICreate("Select a subtitle", 284, 108)
    $Combo1 = GUICtrlCreateCombo("", 16, 32, 249, 25, BitOR($CBS_DROPDOWNLIST,$CBS_AUTOHSCROLL))
    For $i = 0 To UBound($subtitleList) - 1 Step 1
        GUICtrlSetData($Combo1, $subtitleList[$i])
    Next
    $Button1 = GUICtrlCreateButton("Load", 192, 64, 75, 25)
    $Label1 = GUICtrlCreateLabel("Choose A Subtitle:", 16, 8, 91, 17)
    GUISetState(@SW_SHOW)

    While 1
        $nMsg = GUIGetMsg()
        Switch $nMsg
            Case $GUI_EVENT_CLOSE
                Exit
            Case $Button1
                $subtitle = GUICtrlRead($Combo1)
                _RunYourCode()
        EndSwitch
    WEnd
Else
    $subtitle = $subtitleList[0]
    _RunYourCode()
EndIf

Func _RunYourCode()
    ; Insert your code to play the movie with the selected subtitle.
EndFunc

sleepydvdr , you wrote the code so quickly.

(1) In _RunYourCode I want to run following command

k -subfont-text-scale 3 -fs -vf screenshot,expand=0:-40:0:0 <video_file> -sub <subtitle-file>

k.exe is a binary present in my system path

<video_file> is full path of video file that invoked my autoit program , so it should be $CmdLineRaw inside double quotes.

<subtitle-file> should be the file I selected in drop down list (ofcourse , with full path & inside double quotes)

I think I have to create a suitable string then use Run("string")

_RunYourCode can use $filecount to determine if video should be run with or without subtitle.

So , what should I write in Func _RunYourCode() ?

(2) Also , I get "error:variable used without being declared" if folder containing video file has no srt files.

I think $subtitleFile will be -1 if no srt file found .

Thank You.

Another thing , I noticed that functions in your code point to relevant autoit documentation.
