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.

Replace avcodec_get_chroma_sub_sample with the recommended

avcodec_get_chroma_sub_sample is deprecated and generates a warning

Allow filters to handle larger frames.

For now, check the image size.
Inspired by a patch from Paul B Mahol.

Invalid sizes would be detected later by allocation failures,
detecting problems earlier is cleaner.
