Comment (by elioxia):

 I can confirm ffmpeg does not freeze when calling SDL_PumpEvents() at the
 end of sdl_write_packet.
 Since sdl_write_packet may be called from any thread but windows uses per
 thread message queue, a proper fix will need a dedicated thread for sdl
 initialization and messaging.
