Previously if only -y was used then nothing happened, if only -x then zero
window height was set which is undefined in SDL and caused a black window.

From now on if only one dimension is set we calculate the other based on
size/aspect of the shown content.

At present, left and right keys are hardcoded to seek by 10 seconds.

After a seek we drop all frames from the filter anyway. Audio filters already
had a similar approach.

Current ffplay code assumes that the read thread is in its main loop before any
key events are captured, but apparently on IOS even keypresses without a window
are forwared.

Fixes ticket #7252.

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.

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
3bd2228d.
