Hi, When using the VLC executable that comes with the package, after hitting button to set 'B' and initiate loop playback the player immediately goes to the 'A' point and begins playback as expected. However when doing the same in my python program using the vlc python api (vlc.py), the video immedi...

Please ignore my question, I found that yes indeed passing '--demux=m4v,mp4,wmv' solves the issue.
Thank you,

is it possible I should add "--demux h264" ?
Thanks,

As subject says,..have many .m4v files that play fine with the desktop app, vlc.exe. However, when I try to load & play them via the python api, they won't play, no message, no error. I can play .wmv/.mov files via python api just fine though. What am I doing wrong? Do I need to specify some '--...

Hi Remi, Thank you for your reply.
Apologies if I was vague, but the solution that worked for me didn't require any modification to my code,
I simply installed 64-bit 2.2.8 and now it works,
Thank you again,

Hi again Remi, thought you might want to know,
Continued to have difficulty getting 3.0.4 to work with PyQt4,...saw an earlier thread, uninstalled 3.0.4 and installed 2.2.8 (WeatherWax) and now it works.
Thank you,

Ahh, yes, that was the problem I think..I found a 64 bit build of VLC here:

http://download.videolan.org/pub/videol ... 0.4/win64/

Now, the cdll() load call above works...

Sorry I didn't catch this earlier,...Thank you for your message, Cheers,

hmm, i think this may be my problem, (run in Cygwin) > python -i Python 2.7.7 (default, Jun 1 2014, 14:21:57) [MSC v.1500 64 bit (AMD64)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> from ctypes import cdll >>> lib = cdll...

Hi again,..I'm using a 64-bit build of Python 2.7, I thought there was a 64-bit version of VLC, but now I'm not so sure...

Would ctypes() in the 64-bit Python have issues loading a 32-bit libvlc.ddl ?
Is there a 64-bit build of VLC ?

Thank you,

Hi Remi, Thank you for your reply. Could you elaborate a bit more on your answer? I don't do a lot of Win-specific programming... While I do know what 'COM' is generally speaking and encountered it a few times over the years, I'm not familiar with the term 'COM STA', though I did google it, etc ;-) ...

Just to clarify further,..

My app imports vlc.py (just simply import vlc)...

That actual error message I believe originates from mmdevice.c

I am not (re-)compiling the original source of VLC,...vlc.py finds & loads libvlc.dll,etc..

Thank you,

I've written a PyQt4 app that uses VLC. I've primarily developed it on a Linux machine but it's intended for use on Win7-64 host. When run on Linux, works fine. When run on Win7, the exact same code returns the following error message: >> plugin path: C:\Program Files\VideoLAN\VLC >> Warning: option...
