Hello.

I'm using the following functions to get video resolution:

libvlc_media_parse(m_media);
libvlc_video_get_size(m_player, 0, &x, &y)

This works with .flv videos but doesn't work with .mpg ones.

I've tried to look inside the 'libvlc_video_get_size' function and saw that 'libvlc_media_get_tracks_info(p_mi->p_md, &info)' call returns zero on .mpg files.

I can play all these .mpg videos via VLC player and can see their resolution too.

Where's my mistake?

VLC plays the file. I expect you can get the resolution if you play the file and wait for the correct event (e.g. "vout").

Unfortunately, (pre)parsing cannot provide all infos for all formats.

I've tried this, but it didn't work.

I've created an event manager for my player to wait for libvlc_MediaPlayerVout event:

Code: Select all

libvlc_event_manager_t *managerPlayer = libvlc_media_player_event_manager(mediaPlayer);
libvlc_event_attach(managerPlayer, libvlc_MediaPlayerVout, &getSize, mediaPlayer);

When libvlc_MediaPlayerVout event triggered, my function getSize calls libvlc_video_get_size which returns 0 (success), but still sets video dimensions x and y to 0.

Am I missing something?
