JVLC addBroadcast

[JMartin]

Hello. I'm using JVLC for windows with jvlc-0.9.0-20070310 and I can't run my webcam through JVLC.

When i put, "vlc -vvv dshow:// :dshow-vdev="USB2.0 WebCam PRO" :dshow-adev="" :dshow-size="" :sout=#display{dst=display}" in console, it work correctly, but i don't know how to do in java.

Code: Select all

JVLC video=new JVLC(); String[] options={"dshow-vdev=\"USB2.0 WebCam PRO\""}; String output="#display{dst=display}"; video.vlm.addBroadcast("webCam", "C:/Temp/guetta.avi", output, options, true, false); video.vlm.setOutput("webCam", output); video.vlm.playMedia("webCam");

Exception:
[00000306] main playlist error: Reloading playlist not implemented.
org.videolan.jvlc.VLCException: Media webCam creation failed
at org.videolan.jvlc.VLM._addBroadcast(Native Method)
at org.videolan.jvlc.VLM.addBroadcast(VLM.java:39)

Sorry for my English. Thanks.

video.vlm.addBroadcast("webCam", "C:/Temp/guetta.avi", output, options, true, false);

change to "video.vlm.addBroadcast("webCam", "dshow://", output, options, true, false);"
have a test!

You can also try something like this(haven't proof-read this, but i have a similar setup working):

Code: Select all

JVLC jvlc = new JVLC("-vvv", "dshow://", ":dshow-vdev=\"USB2.0 WebCam PRO\"", ":sout=#display"); mediaDescriptor = new MediaDescriptor(jvlc, "dshow://"); mediaPlayer = new MediaPlayer(mediaDescriptor); // you might want to call jvlc.setVideoOutput() here mediaPlayer.play();

Don't have much experience with using VLM with JVLC, so can't comment on that...

I have an DVI Input card attached to my system, I need to render its input on my canvas so I used the same approch described in this thread but I am getting below log and noting is available on my canvas.

*** LibVLC Exception not handled: No active input
Set a breakpoint in 'libvlc_exception_not_handled' to debug.

Here is snapshot of my implementation.
String[] arg = new String[4];

arg[0] = "-vvv";
arg[1] = "dshow://";
arg[2] = ":dshow-vdev=\"DVI hardware\"";
arg[3] = ":sout=#display";
jvlc = new JVLC(arg);

MediaDescriptor mediaDescriptor = new MediaDescriptor(jvlc,
"dshow://");
MediaPlayer mediaPlayer = new MediaPlayer(mediaDescriptor);
jvlc.setVideoOutput(canvas);
mediaPlayer.play();
Kindly tell me where am I wrong. Thanks in advance.
