I've tested VLCPlayer only under Linux and only with libvlc ver.1.1.11
(libvlc interface have changed from version 1.0.9) therefore sorry. Use last version of lib.

Hi Sergey,

I couldn't link VLCPlayer until I replaced link option "-lvlc" with library "vlc".

Thanks for testing! I'll try your variant.

(BTW, what OS and version of libvlc do you use?)

It seems libvlc runs in the application stack. As a result, the number of controls on the screen along with VLCPlayerCtrl is very limited.
I get about 30-40 buttons. (I put on-screen keyboard as ParentCtrl).

The simplest solution, which is still running - make VLCPlayer in a separate pop-up window.

Actually, I uploaded the code here the player mainly, hoping to help the community in solving problems with memory.

I've tested your player on ubuntu 11.10 (beta, gcc 4.6). On 11.04 it links ok. Maybe gcc 4.6 is more sensitive to the order of parameters.
Unfortunately player crashes on both systems just after start (invalid memory access).

Player crashes, because it doesn't check whether libvlc_*_new functions return NULL.

No, I've just forgotten to install VLC (but I had libvlc) Smile.
You should add checking of all pointers returned by libvlc_*_new functions and show error message when they return NULL.

Yes!
VLCPlayer needed:
- libvlc
- vlc
- libsdl

Last version uses SDL_Thread. Therefore it can be compiled without MT flag.

This package has been made as part of a larger work, and successfully solved tasks assigned to it.
The result was a complex product, and not always compiled.
I'll be happy. I hope for your help.
This is why I put pack on bazaar.

Hello Sergey,

I already did some (minor) modifications to solve namespace issues in VLCPlayer ... and SDL package.
Everything compiles, but it always crashes in VLC lib methods : I haven't had time to inspect what goes wrong for the moment.
