Hi all;

I am using libvlc.dll able to trancode webcam.
I used below tutorial to be able to do it.. I couldt succed it with 9.4 version but 8.6c..

http://wiki.videolan.org/LibVLC_Visual_C

there is a problem with vlc 8.6c libvlc.dll and plugins ..

this is the commands buffer part including codec information...
:sout=#transcode{vcodec=h264,vb=1024,scale=1}:duplicate{dst=rtp{mux=ts,dst=%s,port=%s}}

When i run my exe it gives below errors;

Code: Select all

x264 [info]: using cpu capabilities MMX MMXEXT SSE SSE2
x264 [info]: using SAR=12/11
x264 [info]: using cpu capabilities MMX MMXEXT SSE SSE2
[00000298] main private error: cannot add this stream
[00000294] stream_out_rtp private error: cannot ad this stream to the muxer
[00000301] main packetizer error: cannot create packetizer output (s161)

Is it the version problem .. i am not sure if vlc 8.6c supports h264 transcoding..

Thanks

Some how it worked :S... Here it is as below for whom struggling for the same problem...

Code: Select all

char ** commands = new char*[6];
   commands[0] = "vc.exe";
   commands[1] = "dshow://";
   commands[2] = ":dshow-vdev=Philips SPC 900NC PC Camera";
   commands[3] = ":dshow-adev=";
   commands[4] = ":dshow-size=176x144";
 
   len = sprintf(buff,":sout=#transcode{vcodec=h264,vb=1024,scale=1}:duplicate{dst=rtp{mux=ts,dst=%s,port=%d}}",ip,port);
 
	
    commands[5] = (char *) malloc(len+1);

	if(commands[5] == NULL){
	printf("no memory\n");
	}else{	   
	strcpy(commands[5],buff); 
	}


    i_ret = (VLC_Init)(vlc_id, 6, commands );
