Hello,

I am trying to set a marquee value for my player and update it whenever I recieve a value from a server. I could manage to set the first value of the marquee but could not change afterwards. Here, the code portion about how I initialize the marquee:

libvlc_video_set_marquee_int(this->m_pSimulatorController->getVLCPlayer()->getMediaPlayer(), libvlc_marquee_Enable, 1);
libvlc_video_set_marquee_string(this->m_pSimulatorController->getVLCPlayer()->getMediaPlayer(), libvlc_marquee_Text, ("SOME_TEXT");
libvlc_video_set_marquee_int(this->m_pSimulatorController->getVLCPlayer()->getMediaPlayer(), libvlc_marquee_Opacity, 200);
libvlc_video_set_marquee_int(this->m_pSimulatorController->getVLCPlayer()->getMediaPlayer(), libvlc_marquee_Position, ;
libvlc_video_set_marquee_int(this->m_pSimulatorController->getVLCPlayer()->getMediaPlayer(), libvlc_marquee_Refresh, 10);
libvlc_video_set_marquee_int(this->m_pSimulatorController->getVLCPlayer()->getMediaPlayer(), libvlc_marquee_Timeout, 500);
libvlc_video_set_marquee_int(this->m_pSimulatorController->getVLCPlayer()->getMediaPlayer(), libvlc_marquee_Size, 40);
libvlc_video_set_marquee_int(this->m_pSimulatorController->getVLCPlayer()->getMediaPlayer(), libvlc_marquee_Color, 0xffff00);

and in the callback function I try to update the value as:
libvlc_video_set_marquee_int(mp, libvlc_marquee_Enable, 1);
libvlc_video_set_marquee_string(mp, libvlc_marquee_Text, "SOME_OTHER_TEXT);

After the execution of the last two commands, I recieve the correct text (SOME_OTHER_TEXT) via libvlc_video_get_marquee_string(mp, libvlc_marquee_Text)). However, this could not be reflected in the
screen of my player.

I am using VLC 2.2.1 and tried in both Ubuntu 14.04 and Windows 8. If you require any further information, please let me know. Thanks.

1) try disable marque before new text, set text and then enable it again.
2) what GUI framework do you use?

1) Tried what you suggested but it did not work.
2) I am using xw widgets.

thank you for your response by the way.

then what if set text->disable->enable? If I remember correctly I got it working, just not remember how exactly.

I tried all six combinations, but did not help. One could not simply change the text with vlc marquees

then sorry, don't know how to help you

But if you will agree to use Qt...
