@c man begin DESCRIPTION
|
|
|
|
FFplay is a very simple and portable media player using the FFmpeg
|
|
libraries and the SDL library. It is mostly used as a testbed for the
|
|
various FFmpeg APIs.

|
Force displayed height.
|
|
@item -s @var{size}
|
|
Set frame size (WxH or abbreviation), needed for videos which do
|
|
not contain a header with the frame size like raw YUV. This option

exactly, so @command{ffplay} will seek to the nearest seek point to
|
|
@var{pos}.
|
|
|
|
@var{pos} must be a time duration specification,
|
|
see @ref{time duration syntax,,the Time duration section in the ffmpeg-utils(1) manual,ffmpeg-utils}.
|
|
@item -t @var{duration}
|
|

|
|
|
|
@var{duration} must be a time duration specification,
|

see @ref{time duration syntax,,the Time duration section in the ffmpeg-utils(1) manual,ffmpeg-utils}.
|
|
@item -bytes
|
|

|
|
@item -loop @var{number}
|
|
Loops movie playback <number> times. 0 means forever.
|
|
@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
|
|
show audio frequency band using RDFT ((Inverse) Real Discrete Fourier Transform)
|
|
@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).
|
|
|
|
@item -i @var{input_file}
|
|

This option has been deprecated in favor of private options, try -pixel_format.
|
|
|
|
@item -stats
|
|
Print several playback statistics, in particular show the stream
|
|
duration, the codec parameters, the current position in the stream and
|

explicitly disable it you need to specify @code{-nostats}.
|
|
|
|
@item -fast
|
|
Non-spec-compliant optimizations.
|
|
@item -genpts
|
|
Generate pts.
|
|
@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 -ast @var{audio_stream_specifier}
|
|
Select the desired audio stream using the given stream specifier. The stream
|
|
specifiers are described in the @ref{Stream specifiers} chapter. If this option

|
is not specified, the "best" audio stream is selected in the program of the
|
|
already selected video stream.
|
|
@item -vst @var{video_stream_specifier}
|
|
Select the desired video stream using the given stream specifier. The stream
|
|
specifiers are described in the @ref{Stream specifiers} chapter. If this option
|
|
is not specified, the "best" video stream is selected.
|
|
@item -sst @var{subtitle_stream_specifier}
|
|
Select the desired subtitle stream using the given stream specifier. The stream
|
|
specifiers are described in the @ref{Stream specifiers} chapter. If this option
|
|
is not specified, the "best" subtitle stream is selected in the program of the
|
|
already selected video or audio stream.
|
|
@item -autoexit
|
|
Exit when video is done playing.
|
|
@item -exitonkeydown
|
|
Exit if any key is pressed.
|
|
@item -exitonmousedown
|
|
Exit if any mouse button is pressed.
|
|
|
|
@item -codec:@var{media_specifier} @var{codec_name}
|
|
Force a specific decoder implementation for the stream identified by
|
|
@var{media_specifier}, which can assume the values @code{a} (audio),
|
|
@code{v} (video), and @code{s} subtitle.
|
|
|
|
@item -acodec @var{codec_name}
|

@item -scodec @var{codec_name}
|
|
Force a specific subtitle decoder.
|

|
|
default, use @option{-noautorotate} to disable it.
|
|
|
|
@item -framedrop
|
|
Drop video frames if video is out of sync. Enabled by default if the master
|
|
clock is not set to video. Use this option to enable frame dropping for all
|
|
master clock sources, use @option{-noframedrop} to disable it.
|
|
|
|
@item -infbuf
|
|
Do not limit the input buffer size, read as much data as possible from the
|
|
input as soon as possible. Enabled by default for realtime streams, where data
|
|
may be dropped if not read in time. Use this option to enable infinite buffers
|
|
for all inputs, use @option{-noinfbuf} to disable it.
