the func is only call with step = 1
no need to pass it in the func

Don't free the buffer allocated in ff_wms_parse_sdp_a_line() after
calling avformat_open_input(), as it may free it and replace it with
another one.

This reverts commit 626d200e.

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.
