vlcxamarin's Issues

[linker] libvlcjni.so has text relocations - app crashes

Hello there
First, thanks for putting together this great wrapper for vlc. I am trying to write an xamarin forms app for playing videos. I tried to use your library on the android part but got following error:

"[linker] libvlcjni.so has text relocations. This is wasting memory and prevents security hardening. Please fix."

It seems to work ok, if I only create a xamarin android solution.
Thanks for your help,
Roger

Video audio only, how to add view?

Did someone may got a video view working?
Videooutput should be something within:

mMediaPlayer.VLCVout.xxx

SIGSEGV Error When Initialising LibVLCLibVLC Object

Hi,

Great job of having the Xamarin bindings for libvlc.

While I managed to get this to successfully run the sample project which plays the MP3 file, I am getting a SIGSEGV crash when I implemented it for video playing using TextureView which I have enabled hardware acceleration. Strangely enough, the crash occurs when the LibVLCLibVLC object is initialised.

/************** The Code **************/

_libVLC = new Org.Videolan.Libvlc.LibVLCLibVLC(); // error occurs here

_libVLC.SetOnHardwareAccelerationError(this);
_vv.KeepScreenOn = true;

// Create Media Player
_mediaPlayer = new Org.Videolan.Libvlc.MediaPlayer(_libVLC);

// Set up video output
Org.Videolan.Libvlc.IVLCVout vout = _mediaPlayer.VLCVout;
vout.SetVideoView(_vv);
vout.AttachViews();

Org.Videolan.Libvlc.MediaLibVLC m = new Org.Videolan.Libvlc.MediaLibVLC(_libVLC, this.selectedCamera.RemoteURLMobile);
_mediaPlayer.Media = m;
_mediaPlayer.Play();

/************** The Error **************/

The following is the error I am getting:

[mono-rt] Stacktrace:
[mono-rt]
[mono-rt]
[mono-rt] Attempting native Android stacktrace:
[mono-rt]

[libc] Fatal signal 11 (SIGSEGV) at 0xe8e8ffe8 (code=-387383320), thread 1480 (wer_for_Android)

Any idea what's causing this? My emulator is using armbi-v7a. Target framework is JellyBean 4.1.

I have been pulling my hair for the past 2 days trying to fix this.

Cris

How to play a video

Hello Martijn. I am a bit stuck with your plugin. I can't play any video with it. Could you give me an example on how to do this?
Thanks for your help, Roger

VlcXamarin.Sample not running

output::

can this record phone camera?

Great thanks. It works very well in my Xamarin project playing rtsp links of cameras.

I wonder whether it can access and record the phone camera itself. I'm doing a project which needs to record phone camera and generate HLS segments for live streaming. MediaRecorder cannot do that. So I turn to vlc. Any suggestions are welcome, thanks.

Crash when debugging

When add a breakpoint after the Initialize VLC libs crash the app, it is impossible to debug

Can anyone try playing these videos using libvlcsharp? I don't know why it's not smooth

Playing the following video will get stuck. On any platform, I have tried WinForm, WPF, xamarin.android, xamarin.ios

VLC Events in VlcXamarin

Hi there,

Is there a way assign custom event handlers during the different parts the lifecycle in playing the video? i.e. buffering, opening etc.

I think the C++ libvlc allows u to do so and nVLC for .net lets you set the event handle although limited types of events.

Many thanks.

Cannot find libvlcjni.so

Hello,

First of all, thank you for the project. I'm having an issue when running an app that I'm testing where it says that cannot find some libraries:

08-08 04:06:18.552 W/VLC/LibVLC(10611): Unable to load the anw library: java.lang.UnsatisfiedLinkError: dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/MyApp.MyApp-1/base.apk"],nativeLibraryDirectories=[/data/app/MyApp.MyApp-1/lib/x86, /vendor/lib, /system/lib]]] couldn't find "libanw.21.so"

08-08 04:06:18.552 E/VLC/LibVLC(10611): Can't load vlcjni library: java.lang.UnsatisfiedLinkError: dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/MyApp.MyApp-1/base.apk"],nativeLibraryDirectories=[/data/app/MyApp.MyApp-1/lib/x86, /vendor/lib, /system/lib]]] couldn't find "libvlcjni.so"

What do you think that can be happening? Any suggestions?

Thank you again.

Crash when starting a streaming video

Hello,

thanks for this interesting sample! It could be extremly useful for me if I could get it working...

On my android 4.4 attached via USB each time I start a Streaming Video (that is working in Chrome)
the sample app crashes. I am using the sample app just changed the link to an exisiting MJPEG stream.

From the Visual Studio 2015 Output I guess this could cause the Problem:

class OutputMix interface 0 requested but unavailable MPH=43

Can you please help? Thanks :-)
