JVLC and libfaad_plugin

Postby randgen22 » 26 Jul 2008 02:17

Hello everyone,

I am attempting to use the Java bindings for VLC and am running into an issue with libfaad_plugin. Using the example VlcClient in bindings\java\samples\client\src\main\java, I am able to view a test video file without issues. I noticed that the Playlist class is deprecated, so I modified the example to use the MediaPlayer class instead. I am able to view the video, however, when libvlc_media_player_stop() is called through JNA, the JVM crashes due to

Unhandled exception at 0x6ff61aa6 in javaw.exe: 0xC0000005: Access violation reading location 0x00000004

in the libfaad_plugin library. I tried a few other videos and some cause the JVM to crash in the same way while others do not. I have tested this in both Windows XP and Linux -- libfaad_plugin.dll crashes in Windows and libfaad_plugin.so crashes in Linux. Strangely, I do not see any crashing issues with the standalone VLC binaries on any of the test files I used.

I am using the latest nightly VLC build and JDK 1.6u6.

I have a few questions:
1) What class(es) should I be using if I want to play a video through JVLC? Playlist, MediaList/MediaListPLayer, or MediaPlayer?

2) What could be causing libfaad_plugin to crash? I suspect the video files may be corrupt in some way, but the standalone binary handles them without issues.

Please let me know if I can provide more information to look into this issue. Thank you in advance.

Hi,
could you please attach the hs_err*log file? Which version of jvlc/vlc are you using? Any additional info?

Cheers,
Filippo

Hello everyone,

Unfortunately, no error log files are created when the JVM crashes.

I am using the JVLC bindings that I checked out off git on July 23, 2008 and the VLC nightly build vlc-0.9.0-test3-20080725-1826-win32.exe. After trying various things, I've been able to get a backtrace of sorts on the crash. Here is a transcript of it, along with some VLC output:

Please let me know if there is a way to provide a better backtrace while running JVLC.

I've noticed that while the crash happens often, it does not happen every time. There are a few times when libvlc_media_player_stop() does not crash the JVM. I've also included the modified version of VlcClient that I'm using:

I will try to get a snippet of a movie file that exhibits this behavior. Currently, I have two .MP4 videos that exhibit this behavior. I've also tested a .WMV and .MOV file that seem to work fine. Is it the movie that is corrupt here? Or am I incorrectly using JVLC?

Again, please let me know if I can provide more information to help look into this issue. Thank you again!

Hello all,
I tried to run this sample on Ubuntu - but hit issues. So I have the following two questions; if someone can help with these I can run it on Ubuntu and provide any error outputs that might help in fixing this issue (I will also try this on Mac and provide the output soon):
1. Looks like the latest nightly vlc executable (vlc 9.0 test3) on Ubuntu 8.4 does not have libvlc-new which the libvlccore is looking for (but vlc by itself runs fine). Should I be running this example with jvlc against an older version of vlc executable?
2. Also I didnt know which path to provide for --plugin-path option (I can find it for Windows and Mac OS without issues but didnt know where the plugins are located on Ubuntu).
Thanks,
G

Hi Filippo,

When you said you played the file with no errors, were you using the standalone VLC player or JVLC with the VLCPlayerFrame class that I attached earlier? I don't run into any issues when using the standalone player, but do with JVLC.

1. I'm testing this primarily on Windows, so I don't recall running into that particular file issue. Sorry. :( (I had someone else test the file on his Linux machine to determine that this crashing issue is not Windows-specific.)
2. It should be where VLC copied its library files, so that location isn't fixed. Have you tried /usr/loca/lib/vlc?



Another update:
I've switched back to using the org.videolan.jvlc.Playlist class and it seems to work better now. Calling Playlist.stop() on the troublesome videos does not crash the JVM. I have noticed though that making calls such as playlist.getMediaInstance() while the playlist is not playing causes the JVM to crash. I've been getting around this by ensuring that the calls do not happen unless the video is actually playing. If anyone has a better suggestion, please let me know.

Thanks again.

Okay - if that person is able to run the sample fine on Linux, please update with the version numbers used (so I can use the same).

I tried running this sample on Mac...the frame shows and when I set a local movie file the application dies abruptly. Using playlist did not affect the outcome. Here is the last few lines of the output (This dump is captured when running the sample with "usePlaylist=true" - as mentioned, even if I leave "usePlaylist=false" the behavior is same):

This was on Mac OS X 10.5.4, JDK 1.5, and jvlc-core-0.9.0-SNAPSHOT-20080727.jar with latest nightly build of VLC that I downloaded a few hours ago (vlc-0-1.9.0-test3).

Hi all: I was able to run this sample using the playlist on Windows and Ubuntu. (The other way does not work - the sample just crashes as randgen22 has posted; unlike randgen22 the mediaplayer way never worked for me). I used VLC 0.8.6i and jvlc-core-0.9.0-SNAPSHOT-20080727.jar on both Windows and Ubuntu. However this sample does not work on Mac OS X.
Thanks,
G

Hi all:
Here is the error I get when I run the sample using mediaplayer;

Code: Select all

Hi,
you are using an old libvlc. Update your libvlc to the latest available.

Cheers,
Filippo

Hi giga30,

Here is a video game trailer clip I found that works on my machine with MediaPlayer.
