a live audio/video source. It can also convert between arbitrary sample
rates and resize video on the fly with a high quality polyphase filter.
The command line interface is designed to be intuitive, in the sense
that avconv tries to figure out all parameters that can possibly be
derived automatically. You usually only have to specify the target
bitrate you want.
As a general rule, options are applied to the next specified
file. Therefore, order is important, and you can have the same
option on the command line multiple times. Each occurrence is
then applied to the next input or output file.
Exceptions from this rule are the global options (e.g. vebosity level),
which should be specified first.

The format option may be needed for raw input files.
By default avconv tries to convert as losslessly as possible: It
uses the same audio and video parameters for the outputs as the one
specified for the inputs.

decoder/encoder or a special value @code{copy} (output only) to indicate that
the stream is not to be reencoded.
@var{stream_type} may be 'v' for video, 'a' for audio, 's' for subtitle and 'd'

@section Stream specifiers
Some options are applied per-stream, e.g. bitrate or codec. Stream specifiers
are used to precisely specify which stream(s) does a given option belong to.
A stream specifier is a string generally appended to the option name and
separated from it by a colon. E.g. @code{-codec:a:1 ac3} option contains
@code{a:1} stream specifer, which matches the second audio stream. Therefore it
would select the ac3 codec for the second audio stream.
A stream specifier can match several stream, the option is then applied to all
of them. E.g. the stream specifier in @code{-b:a 128k} matches all audio
streams.
An empty stream specifier matches all streams, for example @code{-codec copy}
or @code{-codec: copy} would copy all the streams without reencoding.
Possible forms of stream specifiers are:
@table @option
@item @var{stream_index}
Matches the stream with this index. E.g. @code{-threads:1 4} would set the
thread count for the second stream to 4.
@item @var{stream_type}[:@var{stream_index}]
@var{stream_type} is one of: 'v' for video, 'a' for audio, 's' for subtitle and
'd' for data. If @var{stream_index} is given, then matches stream number
@var{stream_index} of this type. Otherwise matches all streams of this type.
@item @var{program_id}[:@var{stream_index}]

You can precisely specify which stream(s) should the codec AVOption apply to by
appending a stream specifier of the form
@option{[:@var{stream_type}][:@var{stream_index}]} to the option name.
@var{stream_type} is 'v' for video, 'a' for audio and 's' for subtitle streams.
@var{stream_index} is a global stream index when @var{stream_type} isn't
given, otherwise it counts streams of the given type only. As always, the index
is zero-based. For example
@example
-foo -- applies to all applicable streams
-foo:v -- applies to all video streams
-foo:a:2 -- applies to the third audio stream
-foo:0 -- applies to the first stream
@end example
All codec AVOptions are obviously per-stream, so the chapter on stream
specifiers applies to them
