Help with video playback using activex

[kerplunkwhoops]

Hello

I'm having difficulty playing video using the activex component (v0.9.4) embedded in either a vb6 or .net 2005 app.

I can play the video successfully in the vlc.exe main program, but cannot get it to play in the activex viewer.

I am using an Axis network camera which offers several urls to access the video stream. I have tried some of the available urls - all work in vlc.exe, but none work in the activex component.

Here are the debug logs when trying to play the different streams from the activex component:

I have also tried a video file aswell - again this works in vlc.exe but not activex:

My code is very simple:

Code: Select all

Private Sub Form_Load() Dim lngItem As Long Me.VLCPluginV2.Log.verbosity = 3 lngItem = Me.VLCPluginV2.playlist.Add("http://code.revolunet.com/VLCcontrols/bunny.mp4", "test") Me.VLCPluginV2.playlist.playItem lngItem End Sub

Can anyone help me with this?

Are there any in depth examples of how to use the activex component? The info on the wiki is very minimal.

Many thanks

I faced this issue in Vista. I'm sure it would have reproduced in any windows version. The problem was that the ActiveX control was trying to load plugin DLLs from C:\Program Files\VideoLAN\VLC\plugins folder. Those DLLs were inturn dependent on certain DLLs in C:\Program Files\VideoLAN\VLC folder. Since the C:\Program Files\VideoLAN\VLC folder was not in path, IE was not able to resolve those DLLs and hence the plugin DLL load failed. I added the C:\Program Files\VideoLAN\VLC folder to PATH (environment variable) after which the plugin DLLs loaded properly and video started showing up.

I would call this a bug in VLC ActiveX. These dependencies should have been taken care of during the installation but unfortunately not so.

facing the same prob with 0.9.4 within the browser plugin i only get audio no video via RTSP i thought it was something to do with avi files but apparently its not the case. would you know of any 0.9 builds that may not have this problem? because i really like 0.9's pause and resume capabilities as compared to 0.8.6(good with seeking forward and back not pause and resume) when it comes to VOD
