Merge remote-tracking branch 'qatar/master' 

* qatar/master:
  avconv: extend -r to work on any input stream.
  doc/avconv: expand documentation for the -s option.
  avconv: don't print filters inserted by avconv in stream mappings.
  avconv: merge configuration code for complex and simple filters
  avconv: split configuring input filters out of configure_complex_filter

Conflicts:
	configure
	doc/ffmpeg.texi
	ffmpeg.c
	tests/ref/fate/idroq-video-encode

@item -vframes @var{number} (@emph{output})
Set the number of video frames to record. This is an alias for @code{-frames:v}.
@item -r[:@var{stream_specifier}] @var{fps} (@emph{input/output,per-stream})
Set frame rate (Hz value, fraction or abbreviation), (default = 25). For output
streams implies @code{-vsync cfr}.
Set frame rate (Hz value, fraction or abbreviation).
As an input option, ignore any timestamps stored in the file and instead
generate timestamps assuming constant frame rate @var{fps}.
As an output option, duplicate or drop input frames to achieve constant output
frame rate @var{fps} (note that this actually causes the @code{fps} filter to be
inserted to the end of the corresponding filtergraph).
@item -s[:@var{stream_specifier}] @var{size} (@emph{input/output,per-stream})
Set frame size. The format is @samp{wxh} (default - same as source).
Set frame size.
As an input option, this is a shortcut for the @option{video_size} private
option, recognized by some demuxers for which the frame size is either not
stored in the file or is configurable -- e.g. raw video or video grabbers.
As an output option, this inserts the @code{scale} video filter to the
@emph{end} of the corresponding filtergraph. Please use the @code{scale} filter
directly to insert it at the beginning or some other place.
The format is @samp{wxh} (default - same as source).
@item -aspect[:@var{stream_specifier}] @var{aspect} (@emph{output,per-stream})
Set the video display aspect ratio specified by @var{aspect}.
