FFplay is a command-line media player provided by FFmpeg multimedia framework and supports numerous video and audio filters.
It can play a variety of media formats. Also, it comes with libraries and utilities for encoding, decoding, and streaming audio and video.
Whenever the data is received from a multimedia source, such as a file or network stream, FFplay decodes and renders it.
For decoding and decoding the media data, which might be in a variety of formats and codecs, it makes use of the FFmpeg libraries.
The video and audio output drivers receive the media data once it has been decoded and display it on the screen and play it through the audio device, respectively.
FFplay is a flexible player because it supports various media formats and codecs.
Additionally, a number of functions are supported, including audio filtering, frame rate control, and video scaling.
In addition, it offers a number of command-line parameters to alter how it behaves, including choosing a particular audio or video stream, modifying playback speed, and changing the video output.
Following are the video and audio formats supported by FFplay:
Additionally, it supports a number of audio and video codecs, such as:
FFplay is a strong and versatile media player that may be used for many things, including:
- FFplay, a flexible player, can be used to verify and correct programs that utilize the FFmpeg libraries.
- Using FFplay, programmers may confirm that their code properly decodes and renders media data.
- Over a network, FFplay can be used to play a variety of multimedia streams, including video and audio streams.
- It is an effective tool for playing various media types because it supports a large variety of codecs and formats.
- By presenting current information about the stream, such as bitrate, frame rate, and resolution, FFplay may be utilized for tracking network streams.
- It can thus be used as a tool for network-wide video and audio stream monitoring.
- Subtitles can be displayed in a variety of formats, including SRT, ASS, and SSA, thanks to FFplay.
- It can be used to play video content with subtitles as a result.

FFplay provides the
-vol flag with a value between
1000 whereas, the default value is 100, and 0 means mute the sound.
Here’s an example command to increase the volume to 200. Use the below command to increase the volume:
ffplay -volume 200 <path_to_media_file>
At the same time, you can use the
- keyboard keys to increase or decrease the volume during playback.
Note: It is advised to set the volume to a comfortable level because turning up the volume too high may result in distortion and lower the overall sound quality.
FFplay stores the frames of the video it is playing in a buffer or queue.
With the help of the
-min_frames parameters, you can manage the size of this queue.
-min_frames option specifies the least number of video frames that must be buffered before playback can begin, whereas the
-max_delay option specifies the maximum number of video frames that can be stored.
The maximum delay and the minimum number of frames are both set by default to 10 seconds and 2, respectively.
For example, if you want to increase the size of the queue to 40 seconds, you can run the following command:
ffplay -max_delay 40000000
This will set the maximum delay to 40,000,000 microseconds, which is equal to 40 seconds.
Note: Extending the queue could extend the buffering period and postpone the moment when playback begins.
FFplay is written in C Programming language that is ideal for multimedia applications like the processing of audio and video because it allows for effective low-level memory management and gives users direct access to hardware resources.
Here is the list of basic steps to use FFplay from the command line:
Open the terminal window and navigate to the folder/directory where you wish to play the video. You can use
cdto locate the file.
ffplayfollowed by the path to the video file. For instance, if you want to start a video.mp4 located in the current directory then, type:
Enterto execute the command and FFplay will start playing the video file.
You can also use the following keyboard shortcuts to manage the playback:
Spacebar: Pause and resume playback
Left arrow: Rewind
Right arrow: Fast forward
Up arrow: Increase volume
Down arrow: Decrease volume
Esc: Quit FFplay
Add more command-line parameters to FFplay’s configuration to alter its behavior. Use the
-vnoption together with the location of the media file, for instance, to play only the audio stream of a media file:
ffplay -vn audio.mp3
You can explore the other options and features of FFplay by executing
ffplay -hin the command line. This will provide you with a list of available options and their uses.
This is a brief introduction to using FFplay from the command line.
