@chapter Description |
|
@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. |

@item -y @var{height} |
|

|
@item -s @var{size} |
|

|
not contain a header with the frame size like raw YUV. This option |
|
has been deprecated in favor of private options, try -video_size. |

|
@item -an |

|
@item -bytes |
|

|
@item -nodisp |
|
Disable graphical display. |
|
@item -f @var{fmt} |
|
Force format. |
|
@item -window_title @var{title} |
|
Set window title (default is the input filename). |
|
@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} |
|
Read @var{input_file}. |
|
@end table |
|
|
|
@section Advanced options |
|
@table @option |
|
@item -pix_fmt @var{format} |
|
Set pixel format. |
|
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 |
|
the audio/video synchronisation drift. It is on by default, to |
|
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_number} |
|
Select the desired audio stream number, counting from 0. The number |
|
refers to the list of all the input audio streams. If it is greater |
|
than the number of audio streams minus one, then the last one is |
|
selected, if it is negative the audio playback is disabled. |
|
@item -vst @var{video_stream_number} |
|
Select the desired video stream number, counting from 0. The number |
|
refers to the list of all the input video streams. If it is greater |
|
than the number of video streams minus one, then the last one is |
|
selected, if it is negative the video playback is disabled. |
|
@item -sst @var{subtitle_stream_number} |
|
Select the desired subtitle stream number, counting from 0. The number |
|
refers to the list of all the input subtitle streams. If it is greater |
|
than the number of subtitle streams minus one, then the last one is |
|
selected, if it is negative the subtitle rendering is disabled. |
|
@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} |
|
Force a specific audio decoder. |
|
|
|
@item -vcodec @var{codec_name} |
|
Force a specific video decoder. |
|
|
|
@item -scodec @var{codec_name} |
|
Force a specific subtitle decoder. |
|
|
|
@item -autorotate |
|
Automatically rotate the video according to presentation metadata. Enabled by |
|
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. |
