Hello,

I have been looking into launching playlist files (ie: M3U files) from JVLC. There are several classes related to playlists (MediaList, MediaListPlayer etc.), but it seems that these classes were created to build playlists from single files (ie: add several individual MP3's to a MediaList and play it).

Is there a way to play a M3U playlist file? I was thinking there might be a method that will split each file mp3 file inside a M3U file into MediaDescriptors or simply a function that will play all of the songs in the playlist would work as well. Does anything like this exist?

Thanks,
Marc

You should be able to open m3u as same way as any audio file. VLC should do the parsing automatically.

Thanks for your fast response!

When I play M3U files from VLC directly, they work correctly. However, when I load them from JVLC, it doesn't start playing (I load it exactly the same way as I would load a normal mp3). I see the following in the logs:

Did you make the m3u file correct?
I use a simple text editor, and on every line a url to the file(or just the filename if the m3u is in same directory as the files).

like:

http://name.domain.org/data/file1.jpg
http://name.domain.org/data/file2.jpg
http://name.domain.org/data/file3.mp3
http://name.domain.org/data/file4.mp3
http://name.domain.org/data/file5.m4a

...and so on.
Save the file with extension *.m3u instead of for example txt.
More info about m3u: http://en.wikipedia.org/wiki/M3u
Maybe it's a issue of jvlc. http://trac.videolan.org/jvlc/report

You get same messages on VLC if you try to open the m3u file?

The playlist plays correctly if I run it directly from vlc (by double clicking the vlc.exe icon and choosing media, open file...) . Here is the code I use to run any media file (either an MP3 or a M3U playlist). It works correctly for MP3 files but not M3U files (see the logs in my previous post). I have been thinking of upgrading to the latest version of VLC but I wasn't sure if the JVLC jar files have been updated.

Code: Select all

String[] param = new String[] {
        "-vvv",
        "--plugin-path=c:\\vlc-0.9.0-test3-20080727-0004\\plugins", "--no-plugins-cache" };

    jvlc = new JVLC(param);

// Setup the player with the current file to play.
    MediaDescriptor mediaDescriptor = new MediaDescriptor(jvlc, fileName);
    player = mediaDescriptor.getMediaPlayer();
    
    // Set the default volume.
    Audio audio = new Audio(jvlc);
    audio.setVolume(DEFAULT_VOLUME);
player.play();

I have a temporary fix to my problem. In case anyone runs into the same issue, here's what I did:

The following thread talks about a bug in jvlc's handling of the new MediaList format.
viewtopic.php?f=2&t=49612&start=0&st=0&sk=t&sd=a

They suggest that until the problem is solved, we should revert back to using the deprecated PlayList class. This class still works and was good enough for my scenario.
