Hello world !

I have a problem with JVLC 0.9 that I didn't have with the previous release (0.8.x) : I cannot stream to the network anymore.
For information, I am using a compiled version of VLC's trunk of June 2nd 2008 with the following configuration options:

Code: Select all

--build=i386-linux --disable-qt4 --disable-wxwidgets --disable-activex --disable-vcdx --disable-cddax --disable-mozilla --disable-gtk --disable-hal --disable-libcdio --disable-skins2 --disable-portaudio --enable-nls --enable-ffmpeg --with-ffmpeg-faad --with-ffmpeg-mp3lame --with-ffmpeg-faac --with-ffmpeg-zlib --with-ffmpeg-a52 --with-ffmpeg-theora --with-ffmpeg-vorbis --enable-faad --enable-flac --enable-theora --enable-faad --enable-twolame --enable-dv --enable-dvdread --enable-live555  --enable-caca --enable-goom --enable-real --enable-realrtsp --enable-mkv --enable-shout --enable-dvb --enable-dvbpsi --enable-v4l --enable-dvdnav --enable-a52 --enable-libmpeg2 --enable-vorbis --enable-flac --enable-sout --enable-ogg --enable-vlm --enable-mad --enable-libtool --enable-shared --enable-x264 --enable-shared-libvlc

This is a piece of code that used to work with JVLC 0.8.x :

Code: Select all

String streamID = "v4l:///dev/video0";
String location = "v4l:///dev/video0";
String output = "#transcode{vcodec=mp4v,vb=256,scale=1,acodec=mpga,ab=64,channels=2}:duplicate{dst=display,dst=std{access=udp,mux=ts,dst=225.0.0.1:1234}}";
jvlcPlayer.vlm.addBroadcast(streamID, location, output, null, true, false);
jvlcPlayer.vlm.playMedia(streamID);

And this is the piece of code I am trying to get working with JVLC 0.9 (it is quite the same code) :

Code: Select all

String streamID = "v4l:///dev/video0";
String location = "v4l:///dev/video0";
String output = "#transcode{vcodec=mp4v,vb=256,scale=1,acodec=mpga,ab=64,channels=2}:duplicate{dst=display,dst=std{access=udp,mux=ts,dst=225.0.0.1:1234}}";
jvlcPlayer.getVLM().addBroadcast(streamID, location, output, null, true, false);
jvlcPlayer.getVLM().playMedia(streamID);

in this case, the video is playing correcly locally (into a JPanel) but there is no stream generated on the multicast address...

Am I missing something ??

Thanks for helping !

Give the messages and open a bug report.

I finally made it work. So here is how I did to stream a webcam and a microphone on a multicast address :

Code: Select all

String videoMedia = "/dev/video0";
String audioMedia = "/dev/dsp";
MediaDescriptor mediaDescriptor = new MediaDescriptor(jvlc, "v4l://"+videoMedia);
mediaDescriptor.addOption(":sout=#transcode{vcodec=mp4v,acodec=mpga,vb=256,ab=128,deinterlace}:duplicate{dst=standard{access=udp,mux=ts,dst=225.0.0.1:1234},dst=display}");
mediaDescriptor.addOption(":v4l-adev="+audioMedia);
MediaInstance mediaInstance = mediaDescriptor.getMediaInstance();
mediaInstance.play();
jvlc.setVideoOutput(jpanelVideoContainer);
