Hi, everyone. i try to build small function for vlc. I'm using ubuntu 7.10 and VLC 0.8.6f

However, now I face a big problem to compile the code.
My project is to adding small tcp server function to vlc.c file. A client program will send an IPv6 address to the server and the server need to get the streaming video from that address. I study the code for 2 days and I found out that I need to call function that able to start the streaming from that address. The 2 functions are:

playlist_AddItem()
playlist_Control()

Is it correct?
Can anyone tell me how to initiate both the function? For example, client just want tell VLC to start stream from address: ff4f::11
then how can this to be archieved?

Is my initialized got problem? my code is here

Code: Select all

		   vlc_t * p_vlc = NULL;
	               playlist_item_t* p_item;
                       playlist_t *p_playlist;

			p_playlist = playlist_Create( p_vlc );

			char *try;
			try = "[ff4f::11]";

			/*playlist_t *p_playlist =
				(playlist_t *)vlc_object_find( p_intf, VLC_OBJECT_PLAYLIST,
						               FIND_ANYWHERE );*/

			p_item = playlist_ItemNew(p_playlist, try, NULL );

			playlist_AddItem( p_playlist, p_item, PLAYLIST_APPEND, PLAYLIST_END );
			playlist_Control( p_playlist, PLAYLIST_ITEMPLAY, p_item );

Is there are other method?

Please Help me. It's urgent for me. I'm lost now....

Regarding to the previous problem, I found that the problem maybe is due to the libvlc.h and vlc_playlist.h file is not in the same folder with vlc.c file. Hence it have error as shown at previous post.

therefore, i change to add in my program in "libvlc.c" file in function "int VLC_Create( void )". I put my program at there because I found out that
while VLC initialize, It will execute that function. In the libvlc.c file, the libvlc.h and vlc_playlist is define in default. However I found that there are new error while complie.

Code: Select all

Your C code is syntaxically incorrect. Fix it.

Hi, Rémi Denis-Courmont

Thanks for your remind and I found out the reason for the error. The error is cause by the missing bracket in my code.

and for the use of that 2 function, currently I declare that as following and it works.

Code: Select all

playlist_item_t * p_item;	      	        	
playlist_t *p_playlist =(playlist_t *)vlc_object_find((vlc_object_t *)p_vlc, VLC_OBJECT_PLAYLIST, FIND_ANYWHERE );
            	
p_item = playlist_ItemNew(p_playlist, recv_data, NULL );//so far p_item is consider no problem
		
playlist_AddItem( p_playlist, p_item, PLAYLIST_APPEND, PLAYLIST_END );//PLAYLIST_APPEND is how the item being added, 

playlist_Control( p_playlist, PLAYLIST_ITEMPLAY, p_item );//PLAYLIST_ITEMPLAY is the action to do
