[vlc-devel] libvlc_media_list_player_play_item fails after serveral uses

[antonio meléndez]

Hi,

I agree that seems to be a memory or handle problem.... previously to my 
post I tried the app with some memory monitors to see if video memory or 
system memory increases, but I didn't see any memory leak, I can't asure 
that the video memory monitor is really checking the used memory, but 
the point is that I didn't see anything.

I also took a look to directx.c and till the point I have checked it I 
didn't detect any memory leak (mistakes in releasing memory or so). The 
only thing I saw is that overlay is disabled in code, it doesn't take 
the value from the command line, now I'm performing a test with overlay 
but probably it'll crash.

I also tried with direct3d, wingdi glwin32 and opengl. In all this modes 
the app crashes, so it seems that the problem would be in another part.

Any other ideas??

Thank you in advance.

Antonio.
