Hello,

I'm trying to play a video with my own instance of VLC (with vlc 0.9.6 libs), but I have an error I don't know how to fix.
My main function is:

int main(int argc, char* argv[])
{
const char * const vlc_args[] = {
"-I", "dummy", /* Don't use any interface */
"--ignore-config",
"--no-overlay",
"--plugin-path=.\\plugins" }; /* Don't use VLC's config */

// Load of the functions of the libvlc library
if (initLibvlc() == 0)
return 0;

libvlc_exception_t exc;
libvlc_instance_t *instance = NULL;
libvlc_media_t *media = NULL;
libvlc_media_player_t *player = NULL;
int currentPos = 0;


libvlc_exception_init(&exc);

// Creation of the VLC instance
instance = libvlc_new(sizeof(vlc_args) / sizeof(vlc_args[0]), vlc_args, &exc);
raise (&exc);

//Creation of the media player
player = libvlc_media_player_new(instance, &exc);
raise (&exc);

// Creation of the media with the video file
media = libvlc_media_new(instance, "c:\\Temp\\Alpes.avi", &exc);
raise (&exc);

libvlc_media_player_set_media(player, media, &exc);
raise (&exc);

libvlc_media_player_play(player, &exc);
raise (&exc);

sleep(10);

freeLibvlc();
return 0;
}

When I run the executable, I see the first frame of the video, then the executable crashes.
Here are the log:

Anybody could help me?

Is your VLC plugin list correct?

by the way... this is a rewrite, and untested version of what I do... it's a back port to standard C

This adds the path you specify for vlc and vlc/plugins to the current environment.
(Linux... maybe adjust LD_LIBRARY_PATH too?)
And while I'm thinking about this , why doesnt' VLC just do this? libvlc.dll can know its location, and assume plugins is relative to itself. It already has buildin paths to check current directory and currentDirectory/plugins.... why doesn't it just check its own directory?

Thank you for you replies.

Regarding the PATH variable, I added the proposed source code (thanks d3x0r) and I checked that the PATH variable contains the vlc root and plugins directories pathes.
The PATH is OK but that doesn't change anything. It still crashes.

For your information, I can display the video perfectly, using the VLC executable generated by my compilation of the downloaded source code of VLC.
Now, I'm using the same DLLs but called by my own main function, and it fails.

J-B, how can I check the plugin list?

Best regards,
Mobill

Hello,

Is there anybody that could help me?
Tell me if you need further information.

Thanks
Mobill

have you tried adding --verbose=2 ?

Hello,

Thanks D3x0r for your advice. I forgot some of my developer's reflexes.
Unfortunately, I didn't see any decisive information.
Perhaps, you can see something I missed. so here are the logs:
I compared this logs with the ones generated by the use of the VLC executable I compiled without any source modification and run in console mode (the use of the VLC executable does not crash).
The logs seem to be the same.

After that, I just made another test.
I donwloaded VLC-0.8.6i and followed the LibVLC Tutorial 086c ( http://wiki.videolan.org/LibVLC_Tutorial_086c ).
I successfully compiled my own demo.c (I changed the pathes only).
I got exactly the same result: A window appears with the first frame of my video file and VLC crashes.

If I run the executable delivered with VLC-0.8.6i, it can play the same video without any problem.
Of course, I made some tests with other video files and got the same results.

Today, I can say that the problem doesn't seem to be in the video file.
It doesn't seem to be in my test.c file as I got the same result with the "official" demo.c file.
My cygwin compiler seems to be ok as I succesfully compiled VLC (1.0.0) and can start the console mode and play my video file.

So where could be the problem?
In the environment? some variables are wrong or missing?
Other idea?

Thanks for your help.

Hello,

I tried to run my testVlc executable on my old PC with XP Pro... and it plays the video without crashing!
Previously, I was working on my main PC with Vista home premium and the executable has been generated on this one. And there it crashes.

Is there a compatibility problem with Vista?
