Hi All,

I am having some problems with DllCall - specifically using mediainfo.dll.

I have read the information with mediainfo.dll and also the info on dllcall - but for the life of me i can't understand it.... :D

I simply want to make a call to mediainfo.dll and retrieve the Video codec information only. Can someone please help?

The code below is what comes with the mediainfo.dll and this is the autoit example...

;Loading the DLL
$DLL=DllOpen("MediaInfo.dll")

;Info
$Info_Parameters=DllCall($DLL, "wstr", "MediaInfo_Option", "ptr", 0, "wstr", "Info_Parameters", "wstr", "")
MsgBox(0, "MediaInfo_Option - Info_Parameters", $Info_Parameters[0])
$Info_Capacities=DllCall($DLL, "wstr", "MediaInfo_Option", "ptr", 0, "wstr", "Info_Capacities", "wstr", "")
MsgBox(0, "MediaInfo_Option - Info_Capacities", $Info_Capacities[0])
$Info_Codecs=DllCall($DLL, "wstr", "MediaInfo_Option", "ptr", 0, "wstr", "Info_Codecs", "wstr", "")
MsgBox(0, "MediaInfo_Option - Info_Codecs", $Info_Codecs[0])

;New MediaInfo handle
$Handle=DllCall($DLL, "ptr", "MediaInfo_New")

;Open
$Open_Result=DllCall($DLL, "int", "MediaInfo_Open", "ptr", $Handle[0], "wstr", "Example.ogg")

;Inform with Complete=false
DllCall($DLL, "wstr", "MediaInfo_Option", "ptr", 0, "wstr", "Complete", "wstr", "")
$Inform=DllCall($DLL, "wstr", "MediaInfo_Inform", "ptr", $Handle[0], "int", 0)
MsgBox(0, "Inform with Complete=false", $Inform[0])

;Inform with Complete=true
DllCall($DLL, "wstr", "MediaInfo_Option", "ptr", 0, "wstr", "Complete", "wstr", "1")
$Inform=DllCall($DLL, "wstr", "MediaInfo_Inform", "ptr", $Handle[0], "int", 0)
MsgBox(0, "Inform with Complete=true", $Inform[0])

;Custom Inform 
DllCall($DLL, "wstr", "MediaInfo_Option", "ptr", 0, "wstr", "Inform", "wstr", "General;Example : FileSize=%FileSize%")
$Inform=DllCall($DLL, "wstr", "MediaInfo_Inform", "ptr", $Handle[0], "int", 0)
MsgBox(0, "Custom Inform", $Inform[0])

;Get with Stream=General and Parameter=FileSize
$Info_Get=DllCall($DLL, "wstr", "MediaInfo_Get", "ptr", $Handle[0], "int", 0, "int", 0, "wstr", "FileSize", "int", 1, "int", 0)
MsgBox(0, "Get with Stream=General and Parameter=FileSize", $Info_Get[0])

;GetI with Stream=General and Parameter=46
$Info_GetI=DllCall($DLL, "wstr", "MediaInfo_GetI", "ptr", $Handle[0], "int", 0, "int", 0, "int", 46, "int", 1, "int", 0)
MsgBox(0, "Get with Stream=General and Parameter=46", $Info_GetI[0])

;Count_Get with StreamKind=Stream_Audio
$Count_Get=DllCall($DLL, "int", "MediaInfo_Count_Get", "ptr", $Handle[0], "int", 2, "int", 0)
MsgBox(0, "Count_Get with StreamKind=Stream_Audio", $Count_Get[0])

;Get with Stream=General and Parameter=AudioCount
$Info_Get=DllCall($DLL, "wstr", "MediaInfo_Get", "ptr", $Handle[0], "int", 0, "int", 0, "wstr", "AudioCount", "int", 1, "int", 0)
MsgBox(0, "Get with Stream=General and Parameter=AudioCount", $Info_Get[0])

;Get with Stream=Audio and Parameter=StreamCount
$Info_Get=DllCall($DLL, "wstr", "MediaInfo_Get", "ptr", $Handle[0], "int", 2, "int", 0, "wstr", "StreamCount", "int", 1, "int", 0)
MsgBox(0, "Get with Stream=Audio and Parameter=StreamCount", $Info_Get[0])

;Delete MediaInfo handle
$Handle=DllCall($DLL, "none", "MediaInfo_Delete", "ptr", $Handle[0])

;Close the DLL
DllClose($dll)

...ProgAndy will.

@Simplify iT, try this:

$hDLL = DllOpen("MediaInfo.dll")


; New MediaInfo handle
$aMediaInfo = DllCall($hDLL, "ptr", "MediaInfo_New")
$hMediaInfo = $aMediaInfo[0]


; Open
DllCall($hDLL, "dword", "MediaInfo_Open", _
        "ptr", $hMediaInfo, _ ; Handle
        "wstr", "FullPathToSomeVideoFile.avi.mpeg.whatever") ; Full path


; MediaInfo
$aMediaInfoGet = DllCall($hDLL, "wstr", "MediaInfo_Get", _
        "ptr", $hMediaInfo, _ ; Handle
        "int", 0, _ ; StreamKind
        "int", 0, _ ; StreamNumber
        "wstr", "Video_Format_List", _ ; Video Codecs in this file, separated by /
        "int", 1, _ ; KindOfInfo
        "int", 0) ; KindOfSearch

$sMediaInfo = $aMediaInfoGet[0]
ConsoleWrite("Video Codecs in this file, separated by / : " & $sMediaInfo & @CRLF)


; General MediaInfo
$aMediaInfoInform = DllCall($hDLL, "wstr", "MediaInfo_Inform", _
        "ptr", $hMediaInfo, _ ; Handle
        "int", 0) ; Options

$sMediaInfoInform = $aMediaInfoInform[0]

ConsoleWrite($sMediaInfoInform & @CRLF)

DllCall($hDLL, "none", "MediaInfo_Close", "ptr", $hMediaInfo)

DllClose($hDLL)

Just change part below ; MediaInfo to this:

; MediaInfo
$aMediaInfoGet = DllCall($hDLL, "wstr", "MediaInfo_Get", _
        "ptr", $hMediaInfo, _ ; Handle
        "int", 1, _ ; StreamKind <--Video
        "int", 0, _ ; StreamNumber
        "wstr", "CodecID", _ ; Codec ID <-- this
        "int", 1, _ ; KindOfInfo
        "int", 0) ; KindOfSearch

$sMediaInfo = $aMediaInfoGet[0]
ConsoleWrite("Video Codec ID: " & $sMediaInfo & @CRLF)

♡♡♡

Hello,

a time ago, but I want to use the same dll (or commandline) for getting the framerate of a video. As I want to use it for a whole Blu-Ray directory, I have some questions. Perhaps someone knows how to handle this.

with the command line: MediaInfo.exe -f "z:\Medien\Testvideodirectory\" I get all the information including the framerate. But I do not know how to use this with the dll call. Perhaps it could be easier to directly get the information from the command line but I did not get it. Can someone help?

Regards,

Alex

Sorry for digging up this old thread, but I'm trying to extract "Encoded date". This info shows up in red in the console when all extracted info is written, but when that info is extracted directly it writes nothing?

; MediaInfo
$aMediaInfoGet = DllCall($hDLL, "wstr", "MediaInfo_Get", _
"ptr", $hMediaInfo, _ ; Handle
"int", 1, _ ; StreamKind <--Video
"int", 0, _ ; StreamNumber
"wstr", "Encoded date", _ ; Codec ID <-- this
"int", 1, _ ; KindOfInfo
"int", 0) ; KindOfSearch

$sMediaInfo = $aMediaInfoGet[0]
ConsoleWrite("Encoded date: " & $sMediaInfo & @CRLF)

It's in the dll download package. I found this one at this location
