Add Text or Logo not working [LibVLC 2.1.6 & Ubuntu 14.04.5 LTS]

[ShadowMaster]

Dear VideoLAN Forum Users,

I am using LibVLc 2.6.1 RinceWind on Ubuntu 14.04.5 LTS. I want to build a mini player with LibVlc Qt4.8 C++ (Eclipse). I can play, pause and stop the video.

I tried to add text with

Code: Select all

libvlc_video_set_marquee_string(_mediaPlayer, libvlc_marquee_Text, "myText"); libvlc_video_set_marquee_int(_mediaPlayer, libvlc_marquee_X,50); libvlc_video_set_marquee_int(_mediaPlayer, libvlc_marquee_Y, 50); libvlc_video_set_marquee_int(_mediaPlayer, libvlc_marquee_Opacity, 50); libvlc_video_set_marquee_int(_mediaPlayer, libvlc_marquee_Timeout, 4000); libvlc_video_set_marquee_int(_mediaPlayer, libvlc_marquee_Size, 40); libvlc_video_set_marquee_int(_mediaPlayer, libvlc_marquee_Color, 0xffffff); libvlc_video_set_marquee_int(_mediaPlayer, libvlc_marquee_Enable, 1);

and to add a logo with

Code: Select all

libvlc_video_set_logo_string( _mediaPlayer,libvlc_logo_file, "logo.jpeg"); libvlc_video_set_logo_int(_mediaPlayer, libvlc_logo_enable, 1);

but it also not working. The reason is there is a bug in this version but it will be able to show both if we add as example "--sub-filter=marq" to libvlc_new() to show the text on the player. But this is also not working.

Code: Select all

const char * const vlc_args[] = {"--sub-filter=marq", "--no-xlib"}; _instance = libvlc_new (2,vlc_args);

Get the ideas from:

Have someone a solution for this problem ?

Many thanks in advance.

Open it from terminal with command vlc and show us the output which may give some clues.

Thanks for your reply.

Write this in terminal
vlc rtsp-stream --sub-filter logo --logo-file logo.jpeg

and get this:

And the vlc-player shows the stream with the logo. There are no Problems. Only if I try it with code. I think the way I write the code is wrong.
