In this case for libvlc debugging gdb may be used.
See here for more information.

1. run C# application (without debug)
2. run gdb
3. attach <c#_application_pid>
4. use gdb commands, like "continue", "bt" etc

I use libvlc inside Windows C# .Net application for show rtsp video stream. Most of time everything goes well. But sometimes video disappears on my window and I see (via ProcessExplorer) GDI handles leaking. GDI handles count increase for about 10000 and after that it's impossible to create any more...

As stated in answer on stackoverflow I enabled native code debugging.
I already use debug version of libvlc (downloaded from nightly builds).
But now I need a *.pdb (debugging symbols) file for libvlc.dll
How can I obtain this file? Is it even possible?

I have C# WinForms application with using libvlc via P/Invoke.
Some times my app crash when I communicate with libvlc code.
VisualStudio can't show me a point of crashing. Only that app stopped with APPCRASH reason.

Does anybody know how to debug this situation?

Thanks in advance.

On the basis of apparent memory leaks, which I have mentioned in the topic dedicated to another operating system, I decided to more thoroughly identify the cause. I cloned the repository and build VLC from sources used commit 0baad719c5fc47caee6e3429128800a8e1edc6f0 . It took a little longer than I ...

That's not very useful infos. It could be due to memory fragmentation, caching, or leaks in some library beyond VLC's control... I know that VLC is complicated program with many dependencies. But I'm using end product "VLC player", and I see leaks in that product. If you want to find and ...

To confirm the fact of leaks, I started VLC to receive commands from telnet: vlc -I telnet --telnet-password=secret --telnet-port=9999 I created a test application which sends telnet commands (play,stop) to vlc in a loop. play, sleeping for 100ms, stop ... and so on. The graph clearly seen a steady ...

I use libvlc in my application, which should run without restarts. Increased memory usage in vlclib with similar regular activities (start / stop playback) excludes the possibility of such an interaction. I believe that the memory usage does not grow indefinitely in such cases. Do you know how to pe...

After multiple start/stop playback of any kind of source (I tested on regular avi file & rtsp source) I see a memory usage increasion (via ProcessExplorer, TaskManager). E.g. when I start playback at first time - I see 116 Mb. After a lot of stop/play commands (tested manually by pressing "...

All that I do is: 1. Create a form on which I want to display the video; 2. Starts playback for a few seconds; 3. Stop the video; 4. Close the window; 5. Repeat steps 1-4 until the error occurs. I do not know whether it is important, but in fact I create 4 controls on a single form. Each control dis...

Thank you for answer, Rémi.

Parasitic windows are gone.
But if previously opened window in ascii mode, now the video is not displayed at all if a similar situation occured.
Tested on vlc-3.0.0-git-20150329-0002-win32.exe

Any suggestions?

Hello everyone. I use libvlc to display the video stream in my .Net program writen on C#. Most of the time everything is stable. But periodically instead of displaying video in designated control (UserControl), library automatically creates an additional window with the title "VLC (Colour AsCii...

Sometimes the call libvlc_media_player_stop() function in GUI-thread leads to deadlocks. And it happens on an almost empty application. There is only the main form with control (like a panel), which carried the image output (assign through libvlc_media_player_set_hwnd()). Timer periodically (every 5...

As I know much better use axVlcPlugin2 instead of axVlcPlugin1. In axVlcPlugin2 double-click makes frame fullscreen size.

After the release of 2.0.5 I compared the behavior of the previous version. It turned out that in the new version there are hang on calls playlist.stop(), which were not in 2.0.4. But I did not succeed on their own to build the library axvlc.dll, that functionality would be equivalent to that which ...

Thanks for answer. I tried make axvlc.dll from revision http://git.videolan.org/?p=npapi-vlc.git;a=commit;h=fed577d6cd886ad35cf6a9d2bb999d283ce0d55e and in result was a dll with different behavior than in official release. In particular, hungs in playlist.stop() calls, which is not appear in offical...

I want to build same axvlc.dll as in official distribution (http://download.videolan.org/pub/videolan/vlc/2.0.4/win32/vlc-2.0.4-win32.exe) How to determine which revision of source files need to use? (http://git.videolan.org/?p=npapi-vlc.git;a=summary) Which version of compiler/linker needed? Thanks...

Try another video source and play simultaneously in different vlc instances (same source for all instances). Do you have initial problem in this case?

Hello, Mark.
Are you using multicast or unicast connection?
May be problem is in same network port number.
What differs in settings between =rtsp://192.168.1.157/stream1.sdp and =rtsp://192.168.1.157/stream2.sdp besides name ofcourse?

I have same problem with parameters http://forum.videolan.org/viewtopic.php?f=16&t=103804 . See bottom of my message at link. You can try to use VLC 1.1.11 for your issue. In that version passing parameters works fine. Checked with "aspect-ratio" option. UPD: Possibly i've got answer f...

Hello I want to play video stream in my C# application. I try to use VLC 2.0.3 ActiveX (v2) to do this. But i have a problem. For test purpose i use this video stream: [url]rtsp://184.72.239.149/vod/mp4:BigBuckBunny_175k.mov[/url] When i open it in VLC player than play well, but when i try to play i...
