Hi,

does anybody have a working example of how to use the streaming server (VLM) functionality. like for example there is the UglyPlayer class to show how a video can be played.

Thanks and Regards,

Maarten.

At the moment VLM functions are being refactored and cleanedup in VLC, so until then they will not be usable in JVLC either.

Hello litlejohn,

do you know if in the latest trunk vlm works in jvlc? I am tryning something and it doesn't seem that it works, but than again I am not an expert in java developing.

I get this error:

Code: Select all

org.videolan.jvlc.VLCException: Media channel1 creation failed
	at org.videolan.jvlc.VLM._addBroadcast(Native Method)
	at org.videolan.jvlc.VLM.addBroadcast(VLM.java:39)
	at test.main(test.java:44)

Thanks

I tried using both the addBroadcast and changeMedia methods but it seems that the parameters aren't what they seem, I put a name in the first parameter and it said it couldn't find the name, so I changed the parameter to the file location and even though the file exists, the error message returned says that it does not.

org.videolan.jvlc.VLCException: Media file://C:/eclipse/rebelproject/jvlc/man.mpg does not exist
at org.videolan.jvlc.VLM._changeMedia(Native Method)
at org.videolan.jvlc.VLM.changeMedia(VLM.java:95)
at au.com.fls.VLCExample.main(VLCExample.java:35)

All I wanted to do was transcode a file to be saved into another file. Although the original VLCExample code from the latest truck works, I don't see how this snippet of code

JVLC jvlc = new JVLC(args);
jvlc.vlm.changeMedia(input, input, output, options, enabled, loop);

can result in an error. This there another way of transcoding without trying to use the vlm?

I have the VLC version 0.8.6b installed and the latest jvlc binary from the trunk.

I am using latest vlc-trunk. My code for adding VLM looks like this

Code: Select all

name = "channel1";
input = "dvb://";
output = "#duplicate{dst=std{dst=227.111.1.1:12345}}";
ch1options = new String[8];
ch1options[0] = "programs=3201";
ch1options[1] = "dvb-adapter=0";
ch1options[2] = "dvb-frequency=12303000";
ch1options[3] = "dvb-srate=27500000";
ch1options[4] = "dvb-voltage=13";
ch1options[5] = "dvb-satno=1";
ch1options[6] = "dvb-caching=500";
ch1options[7] = "sout-udp-caching=500";
		
		
try {
	dvbCard1.vlm.addBroadcast( name, input, output, ch1options, true, false );
} catch (VLCException e) {
	// TODO Auto-generated catch block
	e.printStackTrace();
}

And error I get is:

Code: Select all

Does somebody knows what am I doing wrong. Is it possible that in trunk vlm functionality for jvlc doesn't work!

Hi all!

Finally I could make the VLM work... after trying a lot to find some example on the internet without success.

Basically there are several relevant points to note:
1st) you have to get the latest version/code of jvlc for linux (0.9.0... but the code itself, not the release... i think the vlm option is not enabled in the binary version)
2nd) compiling jvlc with the --enable-vlm option (besides all other hundreds of options that you should enable)
3rd) The option --security-policy=1 is required

after that, you should be able to run something like this:

Code: Select all

JVLC jvlc = new JVLC(new String[]{"--security-policy=1"});
try {
	jvlc.vlm.addBroadcast("Test", "/media/a.avi", "#rtp{mux=ts,dst=224.123.111.101,port=1234,ttl=1}", null, true, false);
	jvlc.vlm.playMedia("Test");

	Thread.sleep(5000);

	jvlc.vlm.stopMedia("Test");
	jvlc.vlm.deleteMedia("Test");

} catch (Exception e) {
	e.printStackTrace();
}

Hope this helps! It worked for me... after waaaaaaaaayyyy tooo much time trying to do this...

ps. Here is a "guide" that I have done about how to compile/install jvlc 0.9.0 on Ubuntu 7.10 (64bits) if you have trouble with this too...

Hi all,

I followed the guide by dsgallo. However, I also got the same problem like kobe08. Did anybody manage or know how to solve this problem?
Thank you in advance.
