[ffmpeg-devel] question about SDL_EventState(SDL_USEREVENT, SDL_IGNORE) in ffplay

[zuo bf]

Hi all,

>From "amiga.sourceforge.net <http://amiga.sourceforge.net>", i got the 
following explanation about SDL_EventState:

This function allows you to set the state of processing certain event type's.
If state is set to SDL_IGNORE, that event type will be automatically dropped
from the event queue and will not be filtered.

 but in ffplay, there is:
SDL_EventState(SDL_USEREVENT, SDL_IGNORE);    And
#define FF_ALLOC_EVENT   (SDL_USEREVENT) And
        case FF_ALLOC_EVENT:
            alloc_picture(event.user.data1);
            break;
And function alloc_picture is called once, is this the right behaviour?
Do i misunderstand something? I mean whether the event loop should receive
a event of FF_ALLOC_EVENT:)


Any help would be greatly appreciated!!!:)
Thanks!
