SDL_QueryTexture and SDL_DestroyTexture require that the input texture
pointer be non-null. Debug builds of SDL will correctly check for this
and break program execution. This patch fixes this by checking the
status of the texture pointer.

avdevice_register_all() is still required to register devices into
lavf (this is required due to lavd being somewhat of a hack).

Typically only a small subset of the SDL texture formats are supported directly
by the SDL renderer drivers, the rest is software emulated. It's better if
libswscale does the format conversion to a hardware-accelerated texture format
instead of SDL.
This should fix video render slowdowns with some texture formats after
3bd2228d05.
