open stream in qt interface

[kj90]

I open and play a stream using the code below. When I run the program, a qt interface of vlc opens up but the stream opens and plays in another window. How would I get the stream to play in the qt interface instead of a separate window?

Code: Select all

const char * const vlc_args[] = { "-I", "qt", "--ignore-config", "--plugin-path=..\\vlc\\include\\vlc", }; libvlc_instance_t * inst; libvlc_media_player_t *mp; libvlc_media_t *m; inst = libvlc_new (sizeof(vlc_args) / sizeof(vlc_args[0]), vlc_args); libvlc_add_intf(inst, NULL); m = libvlc_media_new_path (inst, "rtp://239.255.0.12:1234"); mp = libvlc_media_player_new_from_media (m); libvlc_media_player_set_media(mp, m); libvlc_media_release (m); libvlc_media_player_play (mp); Sleep(10000); libvlc_media_player_stop (mp); libvlc_media_player_release (mp); libvlc_release (inst);

The qt interface shows up because you gave '-I qt' as a parameter to libvlc_new. If you don't want the interface to shows up, just remove theses parameters.
To have the video in the qt interface from libvlc maybe you can try to use "libvlc_add_intf(inst, "qt");"

But I'm not sure to understand what you want to do.

The interface shows up because you called libvlc_add_intf()... Why the heck do you call that function if you don't want to spawn an interface!!!

I would like that the video plays within the Qt interface window, but it doesn't.
How can I force the playback of the video in Qt?
I tried creating the libvlc instance with the -I Qt option and by adding the Qt interface afterwards.
None of them work. The video is always played back in a seperate window (Direct3D Output)

How could I do this?

[Rémi Denis-Courmont]

That works fine. VLC itself is doing exactly that.

[maitrepiet]

Well, not entirely.
What happens for me is that I get 2 windows:
1 with the standard QT interface, a black screen with the traffic cone, and an other in which the video plays.
The controls of the QT interface have no effect on the video that is playing.

What I really want is only one window with the qt interface as primary control. However I still need the possibility to control the video from my c-program as well.

[Rémi Denis-Courmont]

That is not supported and never will be.

libvlc_add_intf(inst, "qt"); has no effect just opens a Dummy QT Interface ,The controls of the QT interface have no effect on the video that is playing on the other window.

1)streaming a mp4 file using libvlc code with -verbose on in the code,
vout window xid module matching field is "any",because of this video is streaming in xcb_window with no user controls.

2)streaming a mp4 file using vlc from terminal with -verbose on,
vlc -vvv video.mp4
vout window xid module matching with qt4 interface and vout window is qt4 which has full user controls ,If vlc player is able to stream video with QT interface ,their should be a way to do the same thing from the c code ,if anyone has streamed the video with QT interface through libvlc code please let me know?
