Mini VLC preview in apps

Hello,
I would like to have a small preview with VLC of a playing stream in my apps. How can I do that ? However I want to continue to use my main apps.
I think it's not possible to embbed the vlc apps in other activity ?
So may be can I start a little VLC player (with size and position parameters) over my apps screen.
If some one have an idea to do that, that's great.
Thank's

I don't think this is supported in any way right now, but you can use Intents to fulfill this or a similar use-case

I start initialize libvlc on button click : BTN_LoadVLC_click()
The VLCApplication instance is not initialise anywhere ? When getAppResources() method is calling a NullPointerExcption is throw.
Maybe someone have an idea ?
Thank's

Good point, that is a bug.

VLCApplication.java does not have a line 93...

At line 89 in the original file ... When I call getAppResources().

According to Android documentation:
http://developer.android.com/reference/ ... eate%28%29
Called when the application is starting, before any activity, service, or receiver objects (excluding content providers) have been created.
Probably you are missing <application android:name="org.videolan.vlc.VLCApplication"> in your AndroidManifest.xml or something.

This is totally wrong anyway, because Libvlc.java should not call VLCApplication

Well, the current purpose of VLC for Android is to be a player, not a VLC SDK. Maybe that will be implemented later on, when we have VLC fully functioning and completely fast and stable.

Thank's for your answer.
I call the VLCApplication constructor, pending a stable version, I can use Libvlc alone.
However, when I call readMedia() that apparent works but I have no video ...
I have a lot of warnings : yuv_rgb_neon filter can't get output picture
That's a problem with hardware decoding ? (when I use directly VLC apps, with the same stream that works fine)
I have also an error before the warning :
Code: Select all
E/VLC(1360): [0x2c3744]: main vout display Failed to set on top
May be that the cause ?

It was clearly one of the purposes when the project was started.
