In particular: always use @table @samp for showing constant tables, add a
few empty lines for improving readability, and specify default value when
missing.

In particular, fix warnings:
** Unknown command with braces `@item' (in doc/filters.texi l. 60XX)

Always evaluate to NULL when the source Picture is not located in the
MpegEncContext.picture array. That will only happen for
next/last_picture_ptr when updating the thread context during h264 frame
threaded decoding, where they will point to elements of ref_list. Since
ref_list is not copied during updating the context and is invalid until
it is constructed for the current slice, there is no point in doing
anything complicated with next/last_picture_ptr, as they will get
updated when the ref_list is filled.

Only power-of-two FFTs are supported; so to get a full spectrum
(that is, one up to Nyquist), the height must be a power of two.

Therefore, change the default height from 480 to 512.
