Hello,
I have a program using vlc win32 sdk + MFC in VS2010。The OS is WIN7, it works well in vlc2.2.8。
the sout option is

Code: Select all

 "--sout=#duplicate{dst=udp{dst=127.0.0.1:1234},dst=display} "
 "--sout-keep"

Now I want to use vlc3.0.6 sdk, vlc.exe can also work well, Using libvlc sdk in the program it can display the video ,but can't stream out .
what's the problem?
Any input would be greatly appreciated!

I'm not sure how you are passing sout options, but streaming output was never supported in LibVLC - so you must have been relying on unsupported and undocumented behaviour that for a reason or other stopped working.

This is my code,It work well in 2.2.8

Code: Select all

	int vlc_argc = 0;
	char *vlc_argv[20];
	CString str;
	str.Format("udp://@:5000");
	vlc_argv[vlc_argc++] = "--network-caching=150";	
	vlc_argv[vlc_argc++] = "--sout=#duplicate{dst=udp{dst=127.0.0.1:1234},dst=display}";
	vlc_argv[vlc_argc++] = "--sout-keep";
	libvlc_instance_t *p_instance1 = libvlc_new(vlc_argc, vlc_argv);
	libvlc_media_t *p_media1 = libvlc_media_new_location(p_instance1, str);	
	libvlc_media_player_t *p_media_player1=libvlc_media_player_new_from_media(p_media1);
	libvlc_media_player_set_hwnd(p_media_player1,dlg->GetDlgItem(IDC_STATIC_DISPLAY)->GetSafeHwnd());
	libvlc_media_player_play(p_media_player1);
	while (1)
	{
		if (dlg->m_Quit)
		{
			break;
		}
		Sleep(1000);
	}
		libvlc_media_player_stop(p_media_player1);
	libvlc_media_player_release(p_media_player1);
	libvlc_media_release(p_media1);
	return 0;

Hi! I had a similar problem. My solution: '--sout' should be moved to libvlc_media_add_option() for VLC 3 and 4 versions;
For example:

Code: Select all

libvlc_media_add_option(p_media1, ":sout=#duplicate{dst=udp{dst=127.0.0.1:1234},dst=display}");
