[MPlayer-dev-eng] [PATCH] corevideo:shared_buffer broken

[Zongyao Qu]

Sorry I am just too lazy to make a serious patch,
since I have too many local changes in the source code.

I will point out where the bug is 

In
static int control(uint32_t request, void *data)

please change this line

case VOCTRL_UPDATE_SCREENINFO: [mpGLView update_screen_info]; return VO_TRUE;

to

case VOCTRL_UPDATE_SCREENINFO: if(!shared_buffer){[mpGLView update_screen_info]; 
return VO_TRUE;};

-----------------
When shared_buffer is used, mpGLView will be nil, so that the code before
this fix will result unknown behavior.

On the other hand, when shared buffer is used, rendering process should be
totally controlled by GUI process, so I think it is OK to just return VO_NOTIMPL.
