Hi All,

I thought that this piece of code may be of use

If anyone has a better way to do it please let me know, as this is my first try and it worked

It uses a "Kworld DVD Maker 2 (USB Device)".

It will record "dshow" for a desired period of time (in minutes) and reboot.
The code as is will not display the Video or Play Audio so it is ideal for setting off a recording and going to bed

The 2nd piece of code will display Video and Audio via the GUI.

To just shutdown the machine change "shutdown /r /t %sec%" to "shutdown /t %sec%"

Each recording is given a unique file name by using DATE and TIME EG....
"VLC_ 2012-09-22 80049.49.ts" by "g:\vlc\VLC_%date:~10,4%-%date:~7,2%-%date:~4,2% %TIME::=%.ts"
It assumes DATE is in the following format "Sat 22/09/2012" you may have to alter the above substringing to get
the ISO date format. The ISO date format is Ideal for sorting

I have yet to work on the TIME portion to cater for single digit HOURS

The Code.....

Code: Select all

@ECHO OFF
set vlc="C:\Program Files\VideoLAN\VLC\vlc.exe"

SET /P min=Please enter the time to record: 
IF "%min%"=="" GOTO Error

SET /A sec = 60 * %min%
ECHO Shutdown will happen in %min% Minutes
shutdown /r /t %sec%

%VLC% dshow:// :dshow-vdev="USB 2861 Device" :dshow-adev="Line (2- USB 2861 Device)"  :dshow-aspect-ratio=16\:9 :sout=#transcode{vcodec=mp2v,vb=9000,scale=1,fps=25,width=720,height=576,acodec=mpga,ab=320,channels=2,samplerate=48000}:duplicate{dst=file{dst="g:\vlc\VLC_%date:~10,4%-%date:~7,2%-%date:~4,2% %TIME::=%.ts"}} :sout-all :sout-keep --qt-start-minimized

EXIT

:Error
ECHO You did not enter a time in minutes! Bye bye!!
PAUSE
:End

To enable Video and Audio use this Code....

Code: Select all

@ECHO OFF
set vlc="C:\Program Files\VideoLAN\VLC\vlc.exe"

SET /P min=Please enter the time to record: 
IF "%min%"=="" GOTO Error

SET /A sec = 60 * %min%
ECHO Shutdown will happen in %min% Minutes
shutdown /r /t %sec%

%vlc% dshow:// :dshow-vdev="USB 2861 Device" :dshow-adev="Line (2- USB 2861 Device)"  :dshow-aspect-ratio=16\:9 :sout=#transcode{vcodec=mp2v,vb=9000,scale=1,fps=25,width=720,height=576,acodec=mpga,ab=320,channels=2,samplerate=48000}:duplicate{dst=file{dst="g:\vlc\VLC_%date:~10,4%-%date:~7,2%-%date:~4,2% %TIME::=%.ts"},dst=display} :sout-all :sout-keep

EXIT

:Error
ECHO You did not enter a time in minutes! Bye bye!!
PAUSE
:End

EXIT

Hi All,

I have refined the BAT File a bit....

Options to shutdown and reboot, Watch and record or just record..

To stop your machine going to sleep comment the line "Rundll32.exe Powrprof.dll,SetSuspendState Sleep
" at the bottom of the code.

All I need to do now is devise a routine that validates the number of minutes entered as "numeric"

Code: Select all

@ECHO OFF
set vlc="C:\Program Files\VideoLAN\VLC\vlc.exe"


REM =========================================================
REM  Build the file name to store the recording in  
REM =========================================================

set "dte=%DATE%
set "tme=%TIME%"
set "datestamp=%dte:~10,4%-%dte:~7,2%-%dte:~4,2%"

if "%tme:~0,1%"==" " (
   set "timestamp=0%tme:~1,1%_%tme:~3,2%_%tme:~6,2%_%tme:~9,2%"
   ) ELSE ( set "timestamp=%tme:~0,2%_%tme:~3,2%_%tme:~6,2%_%tme:~9,2%"
          )

set "file_name=VLC_CR_Capture_%datestamp%_%timestamp%"

REM =========================================================
REM  Get the time to record  
REM =========================================================

SET /P min=Please enter the time to record in Minutes: 
IF "%min%"=="" GOTO Error

REM ========================================================
REM  Convert Minutes to Seconds for RECORD TIME and SHUTDOWN  
REM ========================================================

SET /A sec = 60 * %min%
SET /A ssec = 60 + %sec%

REM ========================================================
REM  Watch while recording?  
REM ========================================================

:WATCHIT
CLS

SET /P watch=Do you want to watch while you record (y or n):

IF "%watch%"=="y" GOTO SHUT
IF "%watch%"=="n" GOTO SHUT

GOTO WATCHIT

REM ========================================================
REM  SHUTDOWN or NOT to SHUTDOWN that is the question :-)  
REM ========================================================

:SHUT
CLS

SET /P shtdwn=Do you want to SHUTDOWN (y or n) :

IF "%shtdwn%"=="y" GOTO DOIT
IF "%shtdwn%"=="n" GOTO DOIT

GOTO SHUT

:DOIT

IF "%shtdwn%"=="y" (
     ECHO You have %min% Minutes to cancel SHUTDOWN with "shutdown /a"
     rem shutdown /r /t %ssec% /d P:0:0 /c "End of VLC Recording to ABORT shutdown /a"
)

REM ========================================================
REM  Record .... Finally :-)  
REM ========================================================


IF "%watch%"=="y" (
%VLC% --run-time=%sec% dshow:// :dshow-vdev="USB 2861 Device" :dshow-adev="Line (2- USB 2861 Device)"  :dshow-aspect-ratio=16\:9 :sout=#transcode{vcodec=mp2v,vb=9000,scale=1,fps=25,width=720,height=576,acodec=mpga,ab=320,channels=2,samplerate=48000}:duplicate{dst=file{dst="g:\vlc\%file_name%.ts"},dst=display} :sout-all :sout-keep --no-overlay --deinterlace={-1} --deinterlace-mode={yadif2x} vlc://quit

Great solution for Windows 7, but I have a problem with Windows 8. The Kworld USB2800D worked fine with Windows 7, BUT I get a black screen trying to get it to play or record with VideoLAN software.
Any suggestions?
Thanks.
