Fri0r project moved from piksel.org to frei0r.dyne.org.

If the first argument can be read as a video size, set that output size
in the scale. This allows to specify in a filtergraph scale=qcif or
scale=320x240.

This is not completely safe, for example in case of a typo in the video
size string the first argument will be read as the input width
expression, giving rise to a confusing comment.

Return an error in case the video size specifications contains spurious
trailing chars, like in "320x240foobar".

Avoid an assert, since now the function supports error code return.

Also update documentation accordingly.

It appears such construct has undefined behavior

Specification mentions 'strg', 'mark', 'regn', 'info', .. chunks
to have data section size larger than chunk's current meaningful
content in order to reserve room for additional data.

There is not really a problem in having two events at the same time.
Even if it's not perfectly correct, it helps remuxing more files
(typically our FATE sample).

Mainly clean up the RTP statistics code, plus a few other obviously
misindentend lines.

Remove some useless comments, de-doxygenize some comments,
add spacing around operators and fix a typo.

sws_flags is not a valid scale option, and thus is ignored.
