@c man begin DESCRIPTION
|
|

libraries and the SDL library. It is mostly used as a testbed for the
|
|
various FFmpeg APIs.

@item -showmode @var{mode}
|
|
Set the show mode to use.
|
|
Available values for @var{mode} are:
|
|
@table @samp
|
|
@item 0, video
|
|
show video
|
|
@item 1, waves
|
|
show audio waves
|
|
@item 2, rdft
|
|

|
|
@end table
|
|
|
|
Default value is "video", if video is not present or cannot be played
|
|
"rdft" is automatically selected.
|
|
|
|
You can interactively cycle through the available show modes by
|
|
pressing the key @key{w}.
|
|
|
|
@item -vf @var{filtergraph}
|
|
Create the filtergraph specified by @var{filtergraph} and use it to
|
|
filter the video stream.
|
|
|
|
@var{filtergraph} is a description of the filtergraph to apply to
|
|
the stream, and must have a single video input and a single video
|
|
output. In the filtergraph, the input is associated to the label
|
|
@code{in}, and the output to the label @code{out}. See the
|
|
ffmpeg-filters manual for more information about the filtergraph
|
|
syntax.
|
|
|
|
You can specify this parameter multiple times and cycle through the specified
|
|
filtergraphs along with the show modes by pressing the key @key{w}.
|
|
|
|
@item -af @var{filtergraph}
|
|
@var{filtergraph} is a description of the filtergraph to apply to
|
|
the input audio.

Use the option "-filters" to show all the available filters (including
|
|
sources and sinks).
|
|

|
|
duration, the codec parameters, the current position in the stream and
|
|
the audio/video synchronisation drift. It is on by default, to

explicitly disable it you need to specify @code{-nostats}.
|

|
@item -sync @var{type}
|
|
Set the master clock to audio (@code{type=audio}), video
|
|
(@code{type=video}) or external (@code{type=ext}). Default is audio. The
|
|
master clock is used to control audio-video synchronization. Most media
|
|
players use audio as master clock, but in some cases (streaming or high

quality broadcast) it is necessary to change that. This option is mainly
|
|
used for debugging purposes.

|
|
@item -vst @var{video_stream_number}
|
|

selected, if it is negative the video playback is disabled.

|
|
refers to the list of all the input subtitle streams. If it is greater
