; Author ........: smashly
; 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.

@mLipok, I picked up some topic that posted on the forum and I do not remember which one it was

@Skeletor I believe this was the original topic that the UDF was posted and although obsolete is the best UDF to play video in my opinion, to be perfect I just needed to play video on the whole screen without the black borders on the sides.

Video 1024 x 768 with screen resolution 1280 x720

Spoiler

 

I wanted it to occupy the whole screen like this:

I think using "winmm.dll" I will not be able to open the video taking up the entire screen, does anyone know of another video UDF that does this?

Full screen 1024x768 video on a 1680x1050 resolution requires scaling. But because of different width x height ratio (4:3 vs 16:10), enlarged to fill one dimension will have the other over- or undersized (hence a cropped- or black bars containing image).

_Video_Open() accepts position and dimension parameters; bars may be removed by cropping or non-cubic scaling (stretching). Bars may be part of a video file itself if for example a 1024x768 video was saved to a 1024x1050 container (scaling requires *visible* image's dimensions in that case).

How do you do this? Can you do it using this UDF?

Untested (haven't downloaded the UDF) but should be close enough (simply recalculates resolution to scale):

#include "Video.au3"

Global Enum  $VIDEO_DIM_X, _
             $VIDEO_DIM_Y, _
             $VIDEO_DIM__ENUM

Global Const $g_sPathFileVideo = 'C:\videofile.avi'

Global       $g_hWnd

_Video_Open_FullscreenCropped()
;_Video_Open_FullscreenStretched()

Func _Video_Open_FullscreenCropped()
    Local Const $aDimWnd = [@DesktopWidth, @DesktopHeight], _
                $aDimVid = _Video_Dimension($g_sPathFileVideo)
    Local Const $iDimMin = $aDimVid[$VIDEO_DIM_X] < $aDimVid[$VIDEO_DIM_Y] ? $VIDEO_DIM_X : $VIDEO_DIM_Y, _
                $iScale  = $aDimWnd[$iDimMin] / $aDimVid[$iDimMin]
    Local Const $aDimRes = [$aDimVid[$VIDEO_DIM_X] * $iScale, $aDimVid[$VIDEO_DIM_Y] * $iScale]
    
    _Video_Open($g_sPathFileVideo, $g_hWnd, 0, 0, $aDimRes[$VIDEO_DIM_Y], $aDimRes[$VIDEO_DIM_X])
    
EndFunc

Func _Video_Open_FullscreenStretched()
    Local Const $aDimWnd = [@DesktopWidth, @DesktopHeight], _
                $aDimVid = _Video_Dimension($g_sPathFileVideo)
    Local Const $iDimMax = $aDimVid[$VIDEO_DIM_X] > $aDimVid[$VIDEO_DIM_Y] ? $VIDEO_DIM_X : $VIDEO_DIM_Y, _
                $iScale  = $aDimWnd[$iDimMax] / $aDimVid[$iDimMax], _
                $iDimOff = $iDimMax = $VIDEO_DIM_X ? $VIDEO_DIM_Y : $VIDEO_DIM_X
    Local       $aDimRes = [$aDimVid[$VIDEO_DIM_X] * $iScale, $aDimVid[$VIDEO_DIM_Y] * $iScale]
    
    $aDimRes[$iDimOff] = $aDimWnd[$iDimOff]
    _Video_Open($g_sPathFileVideo, $g_hWnd, 0, 0, $aDimRes[$VIDEO_DIM_Y], $aDimRes[$VIDEO_DIM_X])
    
EndFunc

@user4157124 _Video_Dimension() did not work for me, I changed to another function but I could not complete your code.
