Hey:
I imported project(use vlcj 3.6.0 in maven settings) into eclipse in Mac, and the project requires jdk1.8, which I did not change.
My VLC.app version is 2.2.1
When I try to launch, it simply doesn't work, without showing any GUI, and throw lots of error.
Then I change vlcj version to 3.8.0(which is latest version by now) in maven settings, and now I can launch the application without any error.BUT when I open a video file from the menu, the application crashes with the following error msg:

_NSJVMLoadLibrary: NSAddLibrary failed for /libjawt.dylib
JavaVM FATAL: lookup of function JAWT_GetAWT failed. Exit

Other info that might be helpful:

First of all, I would like to thank you for maintaining this beautiful library! Everything was fine until the moment I need to change the audio output device. It looks very simple, but I didn't manage to get it to work, so I decided to have a look at the implementation in vlcj-player, but here again I failed. No matter what device I choose, it still use the default one. The only solution I found was to start the playback, pause it, change the output device and then resume the playback, but it only works once.

I tried different versions of vlcj, from 4.0.5 to 4.2.0, but it makes no difference.
Also, I made a little video in order to not be unfounded :)
https://vimeo.com/375696625
I'd like to provide any additional information if needed.

vlcj : 4.2.0
os : Windows 10 10.0 amd64
java : 1.8.0_222 AdoptOpenJDK

What I did

1) Launched the player using:

mvn exec:java -Dexec.mainClass=uk.co.caprica.vlcjplayer.VlcjPlayer

This launches the UI as expected with the following output:

2) Attempt to open a movie using the Media -> Open File menu item.

This crashes the app with:

JavaVM FATAL: lookup of function JAWT_GetAWT failed. Exit

Other Notes

I know VLC4J works on my development machine as I have a test player based on your vlc-javafx project that runs just fine. I'm just reporting this bug for your information.

Also, nice work on VLC4J!! Very well done!

how to play rtsp stream like rtsp://user:[email protected]:554/h264/ch1/main/av_stream with this player ?

Hello!
How do I set the desired subtitle track?
I have been looking for an answer for several days, but without any result.
I looked in the documentation, searched the Internet, but alas.
This:
embeddedMediaPlayer.media().info().textTracks();
Gives me a list of tracks, but how do I turn on the right one?

Thank you in advance!

Ilya Rudnitsky

what are the methods used to access the buffer or know the buffer occupancy level of vlcj in java.?

Hi,
I'm implemented vlc player with clvj library, so i integrated an EmbedMediaplayer into a JPanel , i can control it easily without any problem, sometimes i have to load some video with specific dimension that gives a bad view, so i thought that i can transpose the video to get wide screen and best view, this is easy to do in real time with VLC Player but when i tried to do it in my application i can't find out, Please is there any suggestion that i can add to my code to be ready to transpose my videos in playing time without needs to create another vlcj application with another concept.

best regards

I can open and play mp4 file on MacOSX now, but it throws an exception as below when on windows

Seems to be caused when using the recent files menu to start video.

Need to check threading here too as the event is now (with vlcj-4) delivered on the native thread.

This is the error coming:

Is there any way that i can select video output device. I want to set video output device as Openmax IL.

The current version can't be deployed with maven, because it is pointing to the vlcj version 3.3, which isn't published yet.

I connect ip camera with rtsp ， but the stream is delay about 5 second ， how to set it low delay?

Good day!

Sorry for my english! :)

I made javafx application and use VCLJ. My application worked good. But Can I ask a question?
I need swith to fullscreen.
I read documentation, and see:
mediaPlayer.fullScreen().strategy(new AdaptiveFullScreenStrategy(window));
This "window" - is awt.window

All rigth. But my application is javafx. And I have window only from javafx. And there need AWT.
Help me please! Where I can to find information? How I can convert fx to awt?

Google carefully hides the answer to this question :(((

Can you to help me?

I will be grateful for any help!

Thank you!

Hi, I would like to use some of your code (https://github.com/caprica/vlcj-player) in a desktop app Im creating to download and play videos from internet, I need to play the videos in a separated window and your code is perfect for that , but I need you approbation for that. Im not going to sell the app , Its just a personal project and Im planning to release it. And I will never forget to give you the credit.
If its ok to let me use it , let me know pls. Thanks

Hi,

is it possible to diplay just image instead of video?

Thanks

How do we access the current number of frames in the vlcj buffer and extract them. ie. Methods or links used for this.

Hello
When trying to compile with maven, I receive a message about missing artifact uk.co.caprica:vlcj:jar:4.0.7-SNAPSHOT

Of course, removing the -SNAPSHOT part, fixes the problem.
Maybe this should be the default?
(I am willing to have a pull request if you accept it).

I am trying to adjust the video Brightness / contrast etc. but the vlcj Player does not change the visible video.
I am using mp4 (converted from h264) video. I also tried other sample Videos from the internet but had no success.

Edit: vlc Version 3.0.10

what's wrong with my player?

Hi @caprica

I am trying to run the project locally.
I can build the project without any issue but when trying to run it I got the following errors:

$java -jar target/vlcj-player-2.0.0-SNAPSHOT.jar 
Error: Could not find or load main class uk.co.caprica.vlcjplayer.VlcjPlayer
Caused by: java.lang.NoClassDefFoundError: uk/co/caprica/vlcj/player/renderer/RendererDiscovererEventListener

My system is Linux
Library used: vlcj-4.7.2-SNAPSHOT.jar (build from source)

openjdk version "11.0.9" 2020-10-20 LTS
OpenJDK Runtime Environment Zulu11.43+21-CA (build 11.0.9+11-LTS)
OpenJDK 64-Bit Server VM Zulu11.43+21-CA (build 11.0.9+11-LTS, mixed mode)

I try also with vlcj-4.4.2.jar and the same error as above.

Any idea/suggestion?
