Problem to get duration

[milink]

Hi !
(sorry for my bad english !)
I discovered libVLC yesterday and I tried it.
However I have a problem. I would get the duration of a media, but this code returns -1 two times. In the documentation, it is written that -1 means there is a problem. But I don't know where...

Code: Select all

#include <stdio.h> #include <stdlib.h> #include <vlc/vlc.h> #include <unistd.h> int main(int argc, char* argv[]) { libvlc_instance_t * inst; libvlc_media_player_t *mp; libvlc_media_t *m; /* Load the VLC engine */ inst = libvlc_new (0, NULL); if(inst == NULL) return 0; /* Create a new item */ m = libvlc_media_new_path(inst, "C:\\Users\\Philippe\\Desktop\\Wildlife.wmv"); if(m == NULL) return 0; libvlc_time_t duration; duration = libvlc_media_get_duration(m); printf("%d", duration); /* Create a media player playing environement */ mp = libvlc_media_player_new_from_media (m); duration = libvlc_media_player_get_length(mp); printf("\n%d", duration); /* No need to keep the media now */ libvlc_media_release (m); /* Free the media_player */ libvlc_media_player_release (mp); libvlc_release (inst); printf("\nOk"); return 0; }

Please, say me where is my error.

Read about events in libvlc. You might need to catch the "playing" event before calling the function that gives you duration.

I did this:

Code: Select all

libvlc_media_parse(m); printf("%d", libvlc_media_get_duration(m));

And it returns correctly the duration in ms.

I didn't know there are events in libvlc. Where can I read about it ?
How did you do to get the duration with your way ?

I think you can read about events here:

It doesn't matter what I did. I'm a fool. You'll do it much better.
