That \p stands for "parameter", and it's used by Doxygen (maybe by
Javadoc too?) to mark the worder using a special font, to distinguish
it from the rest of the text, check our doxygen HTML docs if you care
to see with your eyes how it is rendered.
So it basically makes slightly worse the plain text documentation
readability while it slightly improves the HTML/LaTeX output
readability, but in some circumstances may help to improve readability
of the plain text as well:
Puts in the buffer \p out the content of \p in.
Puts in the buffer out the content of in.
making more clear that a word denotes a parameter.
AFAIR in FFmpeg it is used only in some files, namely avcodec.h, in
swscale.h and somewhere in libavutil (mem.h, base64.h), sparsely in
some function of lavfi.
No strong opinion for it, so I leave the choice to Diego if it has to
be considered the "official" FFmpeg documentation style or not.

Fixed and stripped the \p's for consistency with the rest of the file.
