[open] WindowsError: exception: access violation writing 0x00000014

Hi everyone:

I would like to present several clips (.m4v files) in a row by means of the VLC plugin and the Legacy back-end. When I present only one everything is fine, but when I use more than one I'm getting the following error:

WindowsError: exception: access violation writing 0x00000014

Does anybody know what can be the reason for that?

Here is the information displayed in the debug window.

openexp._canvas.legacy.init_display(): enabling hardware surface
openexp._canvas.legacy.init_display(): enabling double buffering
openexp._canvas.legacy.init_display(): video mode ok
openexp.sampler._legacy.init_sound(): sampling freq = 48000, buffer size = 512

Thanks everyone

Hi,

Are you using the version of media_player_vlc that came with OpenSesame 0.27.4? There were some problems with the memory cleanup in that version that I have corrected in the meantime. Could you let us know if replacing the media_player_vlc plugin with the version found at https://github.com/dschreij/media_player_vlc/archive/1.0.zip solves your problem? Thanks!

Hi dschreij,

Thanks for your interest but unfortunately is not working for me. I am getting the following error:

Failed to load plugin 'media_player_vlc'. Error: This plug-in requires that VLC player >1.X is installed in the default location. You can download VLC player for free from >http://www.videolan.org/. Error: [Errno 2] No such file or directory

I installed the latest version of VLC on my computer and it did not work.
I deleted that version and installed the latest 1.X version of VLC from the older versions ftp server of VLC, but that did not work either.

What else can I do?
