Hi everybody!
I'm a begginer at AutoIt and I have some questions
Well, I need to get techincal video information from a video formats files such as file duration, video/audio streams, frames per second, etc. Can AutoIt do this?

PS I used a search but I have not found any topic with the same problem.

Search on forum for MCI_Video.au3

It returned just one link... And I don't see anything in that thread that can help me.

Andreik, it will be cool if you will show me how to use this UDF

[Shady]

is there's somebody who can help me?

[Manjish]

UDF's contain the functions u need.. just include them in ur script, and call them from there.. like this

#include<Video.au3>
$sFile='D:\VIDEOS\friends.mpg';put ur file path here
$dimns=_Video_Dimension($sFile)
MsgBox(4096,"Video Dimensions","Width: "&$dimns[0] & @CRLF & "Height: "&$dimns[1])

[Manjish]

oops forgot to mention.. copy the video.au3 in ur @script directory.. where ur script resides.. or put it in the Include folder in c:\Program Files\AutoIT\Include..

Cheers,

Manjish, thanks, it works!
But I don't understand how to get other info... I use this script:

#NoTrayIcon
#include <Video.au3>
$sFile = 'I:\dc.mpg'
$dimns=_Video_Dimension($sFile)
$getFrameRate=_Video_FrameRate($sFile)
$getLength=_Video_Length($sFile)

MsgBox(4096,"Video Dimensions","Width: "&$dimns[0] & @CRLF & "Height: "&$dimns[1])
MsgBox(64, "Frames Rate", $getFrameRate)
MsgBox(64, "Length", $getLength)

Your example works but other not. 'Frames rate' and 'Length' returns 0. Can you tell me why?

_Video_FrameRate
; Description....: Close a video.
; Syntax.........: _Video_FrameRate($sAlias)
; Parameters ....: $sAlias - Alias name returned by _Video_Open.
; Return values .: Success - Returns the Frames Per Second of the video.
; Failure - Return 0 and @error 1
; @error 1 = Invalid Alias
; Author ........: smashly
; ====================================================================================================

=====
Func _Video_FrameRate($sAlias)

U'll first need to use _Video_Open.. and the use this handle in _Video_FrameRate

[Shady]

Manjish, yes, i've used this but nothing change. it's still returns "0".
Examples:
1st script:

#NoTrayIcon
#include <Video.au3>
$sFile = 'D:\Video\!NEW_VIDEO\AmytivilleHorror.avi'
$hWnd="1280"
$hWnd = "1"
$iX="1"
$iY="1"
$iW="1280"
$iH="720"
$open = _Video_Open($sFile, $hWnd, $iX, $iY, $iW, $iH)
$dimns=_Video_Dimension($sFile)
$getFrameRate=_Video_FrameRate($sFile)
$getLength=_Video_Length($sFile, 0)
MsgBox(4096,"Video Dimensions","Width: "&$dimns[0] & @CRLF & "Height: "&$dimns[1])
MsgBox(4096, "Frames Rate", $getFrameRate)
MsgBox(4096, "Length", $getLength)

and second:

#NoTrayIcon
#include <Video.au3>
$sFile = 'D:\Video\!NEW_VIDEO\AmytivilleHorror.avi'
$hWnd="1280"
$hWnd = "1"
$iX="1"
$iY="1"
$iW="1280"
$iH="720"
$open = _Video_Open($sFile, $hWnd, $iX, $iY, $iW, $iH)
$dimns=_Video_Dimension($sFile)
$getFrameRate=_Video_FrameRate($open)
$getLength=_Video_Length($sFile, 0)
MsgBox(4096,"Video Dimensions","Width: "&$dimns[0] & @CRLF & "Height: "&$dimns[1])
MsgBox(4096, "Frames Rate", $getFrameRate)
MsgBox(4096, "Length", $getLength)

May be you will show me really stable script? ;-)

[Manjish]

1) keep ur video file open..

2) use wingethandle to get the handle of the open video file..

3) use it in _Video_Open..

[Shady]

1) keep ur video file open..

Ok, please look this script:

#NoTrayIcon
#include <Video.au3>
$iX = "1"
$iY = "1"
$iW = "1280"
$iH = "720"
$video = 'I:\dc.mpg'
$hWnd= WinGetHandle("dc.mpg - GOM Player")
_Video_Open($video, $hWnd, $iX, $iY, $iW, $iH)
$dimns = _Video_Dimension($video)
$getFrameRate = _Video_FrameRate($video)
$getLength = _Video_Length($video, 0)
MsgBox(4096, "Video Dimensions", "Width: " & $dimns[0] & @CRLF & "Height: " & $dimns[1])
MsgBox(4096, "Frames Rate", $getFrameRate)
MsgBox(4096, "Length", $getLength)

File is still open, title of window is correct but it STILL returns zeros. Where's my mistake?

[Manjish]

Here's where ur mistake is.. please read the comments in the video.au3 file..

_Video_Open($video, $hWnd, $iX, $iY, $iW, $iH)

C'mon try.. I have pushed u in the right direction.. now find the solution..

[Shady]

Oh my God I'm not so stupid, it works!!
Manjish, thank you very much!!!
So, really stable code:

#NoTrayIcon
#include <Video.au3>
$iX = "1"
$iY = "1"
$iW = "1280"
$iH = "720"
$video = 'I:\Video\DM.avi'
$hWnd= WinGetHandle("DM.avi - GOM Player")
$sDevice = "AVIVideo"
$file = _Video_Open($video, $hWnd, $iX, $iY, $iW, $iH, $sDevice)
$dimns = _Video_Dimension($video)
$getFrameRate = _Video_FrameRate($file)
$getLength = _Video_Length($file, 0)
MsgBox(4096, "Video Dimensions", "Width: " & $dimns[0] & @CRLF & "Height: " & $dimns[1])
MsgBox(4096, "Frames Rate", $getFrameRate)
MsgBox(4096, "Length", $getLength)

So, I have just one question: is it possible to get information about audio and video codecs of file? In comments of Video.au3 I haven't found any solution...

[Manjish]

i don't know of a way to do it in autoit (there maybe.. but haven't found.. so if any1 knows please share).. n i don't have time to find out how it can be done.. try using this.

@ Andreik, your UDF ran videos MKV, MPG, MP4, AVI and reornou the duration of them perfectly, congratulations on the excellent work
