Capture video image

Belini · June 7, 2018

I've tried several ways to capture the video screen but the image always turns black, does anyone have a hint how to capture the image without turning black?

Hi @Belini
Post some code, maybe?

Best Regards.

;
; Remarks .......: If your having trouble with avi playback (eg; playing fast, slow, choppy or no audio)
;                  or a video won't play but it plays fine in any other player ...
;                  Then set the $sDevice parameter to "MPEGVideo"
;                  If the $sDevice parameter is left blank then windows will decide which MCI Device type
;                  to use.
;                  Most current day avi/wmv/mp4 formats dont play properly or at all when windows selects
;                  the mci device type to use.
;                  Windows would default use "AVIVideo" MCI Device type to play avi with mci.
;                  When you specify "MPEGVideo" for an avi and mci fails it then uses the windows native
;                  chain of codecs that would be used by any other player not using mci ;)
;                  Because of this behaviour you can usually play almost any type of video that normally
;                  fails when using mci just by specifying "MPEGVideo" mci device type.
;                  For playing video on an autoit gui then be sure to add the $WS_CLIPCHILDREN style
;                  to your Gui. This will keep the Video dislpayed on your Gui all the time.
; PT-BR :: Observações:
; ... Se você tiver problemas com a reprodução avi (por exemplo, jogar rápido, lento, intermitente ou sem áudio)
; Ou um vídeo não será reproduzido, mas reproduz bem em qualquer outro player ...
; Em seguida, defina o parâmetro $sDevice como "MPEGVideo"
; Se o parâmetro $sDevice for deixado em branco, o Windows decidirá qual tipo de dispositivo MCI usar.
; A maioria dos formatos atuais de avi / wmv / mp4 não jogam corretamente ou quando o Windows seleciona
; O tipo de dispositivo mci a ser usado.
; Windows usaria padrão "AVIVideo" tipo de dispositivo MCI para jogar avi com mci.
; Quando você especifica "MPEGVideo" para um avi e mci falha, em seguida, usa as janelas nativas
; Cadeia de codecs que seriam usados ??por qualquer outro jogador que não usasse mci;)
; Devido a esse comportamento, você geralmente pode reproduzir quase qualquer tipo de vídeo que normalmente
; Falha ao usar mci apenas especificando "MPEGVideo" tipo de dispositivo mci.
; Para reproduzir o vídeo em um gui autoit, então certifique-se de adicionar o estilo $WS_CLIPCHILDREN
; Para o seu Gui. Isto manterá o vídeo dislpayed em seu Gui todo o tempo.

WebCam.zip example works for me most times. If not a restart from windows is needed.

Have you tried using :
_ScreenCapture_Capture and _GDIPlus_Startup()

Belini · June 8, 2018

@AutoBert I could not use functions of this UDF to capture video but thanks for posting because I use another UDF for webcam and I will exchange for this one that you have posted.

@Skeletor tried _GDIPlus_Startup () with _ScreenCapture_Capture and also _ScreenCapture_CaptureWnd but still giving black screen when capturing the image.

;
; Remarks .......: If your having trouble with avi playback (eg; playing fast, slow, choppy or no audio)
;                  or a video won't play but it plays fine in any other player ...
;                  Then set the $sDevice parameter to "MPEGVideo"
;                  If the $sDevice parameter is left blank then windows will decide which MCI Device type
;                  to use.
;                  Most current day avi/wmv/mp4 formats dont play properly or at all when windows selects
;                  the mci device type to use.
;                  Windows would default use "AVIVideo" MCI Device type to play avi with mci.
;                  When you specify "MPEGVideo" for an avi and mci fails it then uses the windows native
;                  chain of codecs that would be used by any other player not using mci ;)
;                  Because of this behaviour you can usually play almost any type of video that normally
;                  fails when using mci just by specifying "MPEGVideo" mci device type.
;                  For playing video on an autoit gui then be sure to add the $WS_CLIPCHILDREN style
;                  to your Gui. This will keep the Video dislpayed on your Gui all the time.
; PT-BR :: Observações:
; ... Se você tiver problemas com a reprodução avi (por exemplo, jogar rápido, lento, intermitente ou sem áudio)
; Ou um vídeo não será reproduzido, mas reproduz bem em qualquer outro player ...
; Em seguida, defina o parâmetro $sDevice como "MPEGVideo"
; Se o parâmetro $sDevice for deixado em branco, o Windows decidirá qual tipo de dispositivo MCI usar.
; A maioria dos formatos atuais de avi / wmv / mp4 não jogam corretamente ou quando o Windows seleciona
; O tipo de dispositivo mci a ser usado.
; Windows usaria padrão "AVIVideo" tipo de dispositivo MCI para jogar avi com mci.
; Quando você especifica "MPEGVideo" para um avi e mci falha, em seguida, usa as janelas nativas
; Cadeia de codecs que seriam usados ??por qualquer outro jogador que não usasse mci;)
; Devido a esse comportamento, você geralmente pode reproduzir quase qualquer tipo de vídeo que normalmente
; Falha ao usar mci apenas especificando "MPEGVideo" tipo de dispositivo mci.
; Para reproduzir o vídeo em um gui autoit, então certifique-se de adicionar o estilo $WS_CLIPCHILDREN
; Para o seu Gui. Isto manterá o vídeo dislpayed em seu Gui todo o tempo.

@Skeletor is right the way I used _GDIPlus_Startup () or have another way to use it along with _ScreenCapture_Capture?

Edited June 9, 2018 by Belini

@Belini

Can you make screenshot of video window by "PrintScreen" button?

It seems like you use basic Windows 7 theme without aero. If so then choose some aero theme and try again.

I tried to run your script on Win7 (with aero theme) and on Win10 and got a normal screenshot for avi-file.

Belini · June 10, 2018

@innl of windows 7 up works but I need to run on older operating systems like windows xp also and in these earlier windows 7 gives black screen in capture!

InnI · June 11, 2018

@Belini

I don't know how to disable the overlay. But if you run a second copy of the player, the overlay will be disabled for this copy, and you can take a screenshot.

Try this function on WinXP. I tested on Win7 with and without aero and got a normal screenshot for avi-file in both cases. Negative effect is a strong flicker.

@innl of the way you did and adding _Video_Play () and _Video_Pause () worked perfectly, thanks for the great help.

Case $capture
    If $Tocando = True Then
        $sFilePath = @ScriptDir & "\scr.jpg"
        If @OSVersion = "WIN_XP" Or Not _WinAPI_DwmIsCompositionEnabled() Then
            _ScreenShot($sFilePath)
        Else
            _ScreenCapture_CaptureWnd($sFilePath, ControlGetHandle($hGUI, "", "VideoRenderer1"))
        EndIf
    EndIf

    Func _ScreenShot($sFilePath)
        Local $aVidPos, $tPoint, $hScr, $iVid
        _Video_Pause($idS)
        $aVidPos = ControlGetPos($hGUI, "", "VideoRenderer1")
        $tPoint = DllStructCreate($tagPoint)
        $tPointX = 0
        $tPointY = 0
        _WinAPI_ClientToScreen(ControlGetHandle($hGUI, "", "VideoRenderer1"), $tPoint)
        $hScr = GUICreate("GUI for ScreenShot", $aVidPos[2], $aVidPos[3], $tPointX, $tPointY, $WS_POPUP, -1, $hGUI)
        GUISetState(@SW_SHOWNOACTIVATE)
        $iVid = _Video_Open($video, $hScr, 0, 0, $aVidPos[2], $aVidPos[3])
        _Video_Seek($iVid, _Video_TimePos($idS, 1))
        _Video_Play($iVid)
        _Video_Pause($iVid)
        _ScreenCapture_CaptureWnd($sFilePath, $hScr)
        _Video_close($iVid)
        GUIDelete($hScr)
        _Video_Resume($idS)
    EndFunc   ;==>_ScreenShot
