The VideoLAN Forums

It seems to me that the property Playing returns an incorrect value. This concerns version 0.9.8.1 of plugin V1, I'm sure this has been working in earlier version.

I am using VB.net 2008, Windows Vista SP1.

This is how I done the test:

-VB.net 2008, create new Windows Forms Application project.
-To Form1, add 1 VideoLAN VLC ActiveC Plugin v1, 1 textbox, 5 buttons.
-Add the code below.
-Start the application
-Enter a path/name of a movie file in the text box
-Click Load
-Click Play
-Click "Check if playing", working correct.
-Click Pause
-Click "Check if playing", working correct.
-Click Play
-Click "Check if playing", NOT working correct.
-NOTE CLICK STOP BEFORE CLOSING THE APPLICATION, WINDOWS MIGHT CRASH OTHERWISE.

VLC is threaded. The value you get from IsPlaying was correct "a certain small amount of time in the past". There is no way to get the correct value unless you lock the input thread, which requires direct access to libvlccore.dll (and will crash VLC if you gets threading wrong).
