Rotate a video via activex in Visual Basic 6

[barnie1989]

Hi,

I've inserted the activex control VLCPlugin21 in my VB application. It works great! Now some videos must be rotated. Is it possible to do this with that contol? Only fpr viewing, not for saving!

Bye and thanks RUDI

You can enable rotate filter from VLC.

You add the rotate option before the name of your media file. Test the parameters in VLC to make sure you have the right ones.

[barnie1989]

that command doesn't work:

VLCPlugin21.Playlist.Add "--video-filter ""rotate{angle=90}"" movie.avi"

[VLC_help]

But it does work when you use it with vlc.exe?

[barnie1989]

YES, with vlc.exe it works! Now tell me how does ist work with the activex component

[VLC_help]

Does video play in ActiveX or it doesn't even start? Can you check the messages?

[barnie1989]

Where I see the messages?

With that command, the video will be played: frmVLC.VLCPlugin21.Playlist.Add "\\server-barnie\FotoDB_FileStore01\Datenfiles\0308\#00308328#MOV03821.MPG"

and here - nothing happend: frmVLC.VLCPlugin21.Playlist.Add "--video-filter ""rotate{angle=90}"" \\server-barnie\FotoDB_FileStore01\Datenfiles\0308\#00308328#MOV03821.MPG"

It seems that in ActiveX the options are added as last parameter.

Thanks... I've tried many versions... The video always will be played, but not rotated. How must I set the options???

Dim loOptionen(1) As String
loOptionen(0) = "video-filter"
loOptionen(1) = "rotate=190"
llHandle = frmVLC.VLCPlugin21.Playlist.Add(gfsGetBildDateiName(glBildID(giSelectedPic)), "MyVLC", loOptionen)
VLCPlugin21.Playlist.playItem 0


Dim loOptionen(0) As String
loOptionen(0) = "--video-filter ':rotate{angle=123}'"
llHandle = frmVLC.VLCPlugin21.Playlist.Add(gfsGetBildDateiName(glBildID(giSelectedPic)), "MyVLC", loOptionen)
VLCPlugin21.Playlist.playItem 0

[VLC_help]

I have no clue how Visual Basic string stuff works, but

loOptionen(0) = "--video-filter ':rotate{angle=123}'"

should prolly be
loOptionen(0) = "--video-filter 'rotate{angle=123}'"
or
loOptionen(0) = "--video-filter=rotate{angle=123}"

[barnie1989]

no chance.. I've tried all combinations... NOTHING!

[barnie1989]

Does really noone knows how to set the option to rotate a video with the activex contol?

[surf_uk]

I'm using a c# vlclib.dll wrapper and the options I send are:

string[] args = {VlcDirectory,
":no-one-instance",
":no-loop",
":no-drop-late-frames",
":disable-screensaver",
":vout=direct3d",
"--no-osd","--ignore-config","--quiet","--video-filter","rotate{angle=180}",
"--plugin-path=" + Path.Combine(VlcDirectory,"plugins")};

Rotate works in with "--video-filter","rotate{angle=180}"

Hi!
It does not work for me.
Now I have:

Code: Select all

..... player.VlcMediaplayerOptions = new[] { "--high-priority", "--no-sout-smem-time-sync", "--clock-jitter=0", "--clock-synchro=0", "--live-caching=0", "--no-osd", "--rotate-angle=120.0", //Funktioniert auch, sogar mit genauen Graden und Kommastellen! "--video-filter=rotate", //Siehe: https://wiki.videolan.org/VLC_command-line_help/ }; player.EndInit();

This works fine when applying before EndInit() !!!
But what I need is to rotate while playing the video. It does not help me to just rotate to a fixed value before at Init because I need to rotate the video live (and also another problem is that this all does not have an effect to my recorded video - it is not rotated...

So my idea was to enter it here:

Code: Select all

string[] option = new string[] { @":dshow-vdev="+Kamera_Gerätename, @":dshow-adev=none", @":dshow-size="+Bildbreite_real+"x"+Bildhoehe_real, @":dshow-aspect-ratio=16\:9", @":live-caching=0", @":clock-synchro=0", //@":sout=#duplicate{dst=file{dst=C:\Users\matthias.mueller\Desktop\test.mp4},dst=display}", //@":sout-all", //@":sout-keep", @"--video-filter","rotate{angle=180}", }; player.Play(new Uri(@"dshow://"), option);

But I don't know any syntax that works... is it possible to make it work?
Is there another solution to rotate the video while playing? I would like to use data from an encoder to rotate in real-time...
