JVLC status

[sherington]

I wanted to clarify one JVLC issue with you. When I have created several JVLC instances (possibly more than 10) in my application (everyone attached to a listener), my JVM crashes.

What are you doing in your callback/listener code? I think you need to be very careful not to re-enter libvlc in the same thread as the callback/listener. I have seen JVM terminations under these circumstances.

It's not easy for me to test what you've asked.

[coolmak]

sounds like a plan. i'l try this.

the biggest problem i guess will be to compile vlc for windows xp/vista....

thank you very much for your verbose answer!

Hi sherington,

I see you are very experienced VLC/JVLC user. I have a project in Java, and I have to know the amount of data in the vlc stream buffer.
Vlc code is a bit comlex, and unfortunately I haven't got enough time to discover it.
Could you give mi any Idea how to add function to vlc native lib, which I can access from java, and it gives back the actual state of the stream buffer.

Thanks a lot!

Hi sherington ,

Thanks for such good example of JVLC, you simplified JVLC use.

I am trying to use JVLC in my java application but struggling to get it run.

I found the steps to execute JVLC in eclipse on this link viewtopic.php?f=14&t=49758 and it is working fine. But when I try to use jvlc.setVideoOutput(c); it is throwing error.
I have executable jar file jvlc-core-0.9.0-SNAPSHOT-20080727. It has LibVlc.class file. As per your earlier post, we need to modify the LibVlc file as per the applications requirement. I am not able to do that, can you give complete steps to create such a file from this jar file. As in the application we have to embed the video in a pan which will be static means there is a pan which will display the video, the position of the pan will not change, only it will play different videos.

Before using VLC in java application I have successfully used VLCObject and VLCControl js files and they are working fine.

Can you suggest something on this.

Hi Sherington,

Thanks for the info.
I've been trying something very similar but haven't gotten lucky.

I used JVLC's LibVlc.java with minor changes & the libVlc tutorial on the VideoLan webpage
I can successfully play a .mp3 file, but not video. I tried mov & mp4 files, but nothing happens. I don't get any error message, and there's not audio or video.
(I'm trying to play a local file)

Am I missing out on any video-related setup/initializing?

I have:

Code: Select all

String vlc_args[] = { "-I", "dummy", "--ignore-config", "--plugin-path=C:\\Program Files\\VideoLAN\\VLC" };

Code flow:

Code: Select all

ex = new LibVlc.libvlc_exception_t(); inst = libvlc_new(args.length, args, ex); med = libvlc_media_new (inst, "D:\\WOW_PearlJam.mov", ex); mp = libvlc_media_player_new_from_media (med, ex); libvlc_media_release (med); int canvasId = (int)Native.getComponentID(canvas); libvlc_media_player_set_drawable (mp, canvasId, ex); libvlc_media_player_play (mp, ex);

Thanks!

I have:

Code: Select all

String vlc_args[] = { "-I", "dummy", "--ignore-config", "--plugin-path=C:\\Program Files\\VideoLAN\\VLC" };

I don't use Windows for my own application, but when I was investigating this my vlc args specified the "plugins" directory underneath vlc, i.e.

Code: Select all

--plugin-path=C:\\Program Files\\VideoLAN\\VLC\\plugins

Also, when things don't work, putting -vvv in your vlc_args might help diagnose the problem.

[sherington]

But when I try to use jvlc.setVideoOutput(c); it is throwing error.

Well, what is the error?

As per your earlier post, we need to modify the LibVlc file as per the applications requirement. I am not able to do that, can you give complete steps to create such a file from this jar file.
Can you suggest something on this.

I would suggest that you use the latest release version of vlc, and get the same tagged version of vlc source code from the repository.

That will contain all of the Java source files you need. Do your edits in those files. You can build the JVLC jar very simply using maven. Use this jar that contains your changes rather than the rather dated JVLC jar file you're using currently.

Note that you don't need to modify LibVlc if it already fits your needs - I just wanted a bare minimum version of my own for the sake of simplicity.

I won't go into the detail of how you get the source code since that's explained on this web-site somewhere already, and I can't tell you how to edit the LibVLc.java file to suit your own application since I don't know it. If you know how to read a C header file, and you know how to build Java applications, that should be enough.

[sherington]

Hi,

I finally got around to bundling up my own Java bindings that have been discussed in this forum topic.

I hope it's ok to post external links here, it's a GPL project in keeping with VLC and the original JVLC bindings.

http://code.google.com/p/vlcj/

If you go to that site, you can check out my bindings and a very basic video player application to demonstrate the bindings do actually work. At present there are no downloads as such, you will need to check out the files from subversion. Instructions are provided. Windows people will need to edit the test application source code to specify the vlc plugins folder. I'd recommend importing it into Eclipse, make your changes, run the test application.

I think it should be quite easy for anyone interested to take what's there and do their own thing with it as there are only really two classes of any note - the new LibVlc and the MediaPlayer class.

I hope someone finds it useful.

I'm basically done with it. For my own application I can get away with using mplayer's slave mode so I'm doing that now instead.

[Jean-Baptiste Kempf]

Very interesting, thanks.

Hi Sherington,

Thanks for your suggestions. Haven't solved the issue yet, but the '-vvv' implies some path related problem.
I did try your project as well and ran into the same issue - plays mp3, but not mov, mp4

I'm using NetBeans.
I tried using

Code: Select all

System.setProperty("java.library.path", "C:\\Program Files\\VideoLAN\\VLC\\plugins");

as well as setting the same JVM run option using -D
I also reconfirmed that all the highlighted DLLs below actually do exist in the same path.
Hopefully you might be able to catch something from verbose output, thanks!

So the -vvv options spits out:

[sherington]

But did you actually try...

Code: Select all

--plugin-path=C:\\Program Files\\VideoLAN\\VLC\\plugins

From what I can remember, when I got this working on Vista I just used the above args, I did not set any Java options via -D nor did I set any System properties.

I can't offer you any more than that.

[kryptonite]

But did you actually try...

Code: Select all

--plugin-path=C:\\Program Files\\VideoLAN\\VLC\\plugins

Yes, I did try that.

It's strange, I could plav a WMV file successfully (video & audio). Tried an AVI file - could hear the audio, but no video.
I thought, maybe it's the order of specifying vlc args; played around with that too.

I guess you're using the RC1.0 candidate? I'm using 0.9.6. I should probably try out 0.9.9
Appreciate your help.

[kryptonite]

Wow! I've been breaking my head all these days, thinking something was wrong with my code.
I upgrade to 0.9.9 and voila..... I can play mp3, mp4, mov, wmv, avi
Seems like the --plugin-path option had problems in earlier releases. Just specifying "--plugin-path=C:\\Program Files\\VideoLAN\\VLC" works!
Thanks again, Sherington.

[Jean-Baptiste Kempf]

Great.

[pablorosatti]

You know if there is (or can it be made) a jvlc based java applet video player? A video player that can be embedded into a webpage.

[kryptonite]

Well, since a Java application works fine, I don't see roadblocks in the applet version.

[ivoire]

Why aren't you sending patches to update the jvlc binding inside the vlc source tree ?

Best regards

[kryptonite]

My app is quite customized and since it's been a learning process for me, it's not modularized well enough for general use.
Once I get through my project deadline though, I'll try to get it into a shareable format.

[ivoire]

That's a good idea. I will try to update the JVLC binding on my own but I'm not really confident with java so it might take a while, so patches are really welcome

[JeffM-35]

Hi,

I finally got around to bundling up my own Java bindings that have been discussed in this forum topic.

I hope it's ok to post external links here, it's a GPL project in keeping with VLC and the original JVLC bindings.

http://code.google.com/p/vlcj/
...
...
I hope someone finds it useful.

Thanks Sherington - you really save me hours getting my project started. Useful and then some. Awesome.

Anyone else looking to grab and go in Win environment, YOU MUST:

Code: Select all

public class TestPlayer { private static final String[] ARGS = {"--plugin-path=C:\\Program Files\\VideoLAN\\VLC\\plugins"};

or it will not work!
thanks again

[ramsestom]

I'm experiencing a problem with the exemple class (TestPlayer.java) under Windows XP.
It throw me the following code:

Code: Select all

Exception in thread "main" java.lang.UnsatisfiedLinkError: Unable to load library 'libvlc': Le module spécifié est introuvable. at com.sun.jna.NativeLibrary.loadLibrary(NativeLibrary.java:160) at com.sun.jna.NativeLibrary.getInstance(NativeLibrary.java:228) at com.sun.jna.Library$Handler.<init>(Library.java:140) at com.sun.jna.Native.loadLibrary(Native.java:372) at com.sun.jna.Native.loadLibrary(Native.java:357) at uk.co.caprica.vlcj.binding.LibVlc.<clinit>(LibVlc.java:52) at uk.co.caprica.vlcj.MediaPlayer.<init>(MediaPlayer.java:49) at uk.co.caprica.vlcj.test.TestPlayer.main(TestPlayer.java:59)

I've tried different path for the libvlc module:

Code: Select all

private static final String[] ARGS = { "--plugin-path=C:\\Program Files\\VideoLAN\\VLC"}

or

Code: Select all

private static final String[] ARGS = { "--plugin-path=C:\\Program Files\\VideoLAN\\VLC\\plugins"}

which are path to the latest vlc release (VLC 1.0.1) installed on my computer

I've also tried with:

Code: Select all

private static final String[] ARGS = { "--plugin-path=C:\\Program Files\\VideoLAN\\VLC_0.9.9"}

or

Code: Select all

private static final String[] ARGS = { "--plugin-path=C:\\Program Files\\VideoLAN\\VLC_0.9.9\\plugins"}

which refer to an install of vlc previous release (VLC 0.9.9)

But nothing works!

Any idear about the origin of my problem would be higly appreciated...

[kryptonite]

It's failing while loading the libvlc dll itself, changing plugin-path value might not help.

Before the call to

Code: Select all

Native.loadLibrary()

try adding:

Code: Select all

NativeLibrary.addSearchPath("libvlc", "C:\\Program Files\\VideoLAN\\VLC");

Hi all,

Just wanted to say a big thank you to sherington for his work on vlcj. I have it working in windows with no fuss. What I'm stuck with is Mac OSX.

I originally had Leopard but had modified quite a bit so was looking at a fresh install.

I did a clean installed Snow Leopard and installed netbeans etc. I managed to get it working but only for a few frames of video before the program quits.

Here is the normal log.

Code: Select all

Playing Fontconfig error: Cannot load default config file Invalid memory access of location 0x20 rip=0x127f3ae64 Java Result: 139

I did have a look at the longer log but the only things that jump at me were the Fontconfig error and the invalid memory access. I really only changed this below:

Code: Select all

private static final String[] ARGS = {//"-vvv", "--ignore-config", "-I dummy", "-V opengl", "--plugin-path=/Applications/VLC.app/Contents/MacOS/modules/"};

the odd thing is if i set -V to dummy. It will play the video file no problem but as its the dummy video output module it wont show anything up on screen.

Any ideas?

[ramsestom]

I encounter a problem when using vlcj with media having path with accentuated characters.
For exemple, If I try:

Code: Select all

mediaPlayer.playMedia("C:\\Documents and Settings\\Tom\\workspace\\VODPlayer\\TMP\\PLAYBUFFER\\karaoké Bouba karaoke.mp4");

VLC report the folowing error:

Code: Select all

As you can see, in the path returned by vlc, the "é" character of "karaoké" has been removed, wich explains that file could not be found

I first suspect a problem linked to jna while transcoding java String object to C char* object but trying a realy simple java code:

Code: Select all

public class HelloWorld { // This is the standard, stable way of mapping, which supports extensive // customization and mapping of Java to native types. public interface CLibrary extends Library { CLibrary INSTANCE = (CLibrary) Native.loadLibrary((Platform.isWindows() ? "msvcrt" : "c"), CLibrary.class); void printf(String format, Object... args); } public static void main(String[] args) { CLibrary.INSTANCE.printf("C:\\Documents and Settings\\Tom\\workspace\\VODPlayer\\TMP\\PLAYBUFFER\\karaoké Bouba karaoke.mp4"); } }

the result is just fine as it prints: C:\Documents and Settings\Tom\workspace\VODPlayer\TMP\PLAYBUFFER\karaoké Bouba karaoke.mp4

So the problem seems to occur at the vlc level. However, runing "vlc.exe C:\Documents and Settings\Tom\workspace\VODPlayer\TMP\PLAYBUFFER\karaoké Bouba karaoke.mp4" in a dos command prompt console is working. So I did not really understand why going through libvlc causes problem. If anybody has an idear...

PS: I've also tryed the "-http-charset=ISO-8859-1" in the vlc arguments line and it do not solve the problem

[jrsyboy_86]

Has anyone been able to implement a JSlider to search thru the video without using the deprecated Playlist class?
