FFmpeg is a cross platform, free, open source media encoder/decoder toolkit. It contains the programs and libraries necessary to convert audio and video into a wide range of formats. FFmpeg was written by Fabrice Bellard (creator of QEMU and the BPG image format).

Installation

USE flags

Some packages know the ffmpeg USE flag for enabling ffmpeg-based audio/video codec support.

USE flags for media-video/ffmpeg Complete solution to record/convert/stream audio and video. Includes libavcodec

X Add support for X11
alsa Add support for media-libs/alsa-lib (Advanced Linux Sound Architecture)
amf Enables support for AMD's Advanced Media Framework (AMF)
amr Enables Adaptive Multi-Rate Audio support
amrenc Enables Adaptive Multi-Rate Audio encoding support with media-libs/vo-amrwbenc.
appkit Enables Apple AppKit framework
bluray Enable playback of Blu-ray filesystems
bs2b Enables media-libs/libbs2b based Bauer stereo-to-binaural filter.
bzip2 Enable bzip2 compression support
cdio Enables audio CD grabbing with dev-libs/libcdio.
chromaprint Enables audio fingerprinting support with media-libs/chromaprint.
chromium Builds libffmpeg.so to enable media playback in Chromium-based browsers like Opera and Vivaldi.
codec2 Enables codec2 low bit rate speech codec support via media-libs/codec2.
cpudetection Enables runtime CPU detection (useful for bindist, compatibility on other CPUs)
cuda Enables CUDA-based acceleration. Mostly used for specific filters.
dav1d Enables AV1 decoding via media-libs/dav1d.
debug Enable extra debug codepaths, like asserts and extra output. If you want to get meaningful backtraces see https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces
doc Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally
encode Add support for encoding of audio or video files
fdk Use external fdk-aac library for AAC encoding
flite Adds a text-to-speech filter based on app-accessibility/flite.
fontconfig Support for configuring and customizing font access via media-libs/fontconfig
frei0r Enable frei0r wrapping in libavfilter
fribidi Enables fribidi support in the drawtext filter.
gcrypt Enables gcrypt support: Needed for rtmp(t)e support if openssl, librtmp or gmp is not used.
glslang Use dev-util/glslang to compile GLSL
gme Enables support for media-libs/game-music-emu for playing various video game music formats.
gmp Add support for dev-libs/gmp (GNU MP library)
gnutls Prefer net-libs/gnutls as SSL/TLS provider (ineffective with USE=-ssl)
gpl Build GPL code. Should be enabled unless you require LGPL binaries.
gsm Add support for the gsm lossy speech compression codec
hardcoded-tables Use pre-calculated tables rather than calculating them on the fly. It results in an increase of approximately 15% in the size of libavcodec, the main library impacted by this change. It enables savings in table generation time, done once at codec initialization, since by hardcoding the tables, they do not need to be computed at runtime. However, the savings are often negligible (~100k cycles is a typical number) especially when amortized over the entire encoding/decoding operation. Improvements are being made to the runtime initialization, and so over time, this option will have an impact on fewer and fewer codecs.
iconv Enable support for the iconv character set conversion library

Video Encoding

This section provides advanced FFmpeg commands for video encoding, allowing users to manipulate video files with precision and flexibility.

Convert video to AVI with specific codecs

This command converts a video file (input_demo.ogv) to the AVI format using the MPEG-4 video codec and MP3 audio codec. The resulting output file will be named my-demo-video.avi. The video codec ensures efficient compression while maintaining good quality, and the audio codec provides compatibility and reasonable file size.

user $ffmpeg -i input_demo.ogv -vcodec mpeg4 -qscale 0 -acodec libmp3lame my-demo-video.avi

Extract frames from video

This command extracts frames from a video file (my-demo-video_cropped.mp4) and saves them as individual images. The "-r" option specifies the frame rate for capturing frames, and the output filenames will be in the format "pic001.png", "pic002.png", and so on. Extracting frames from a video is useful for creating thumbnails, analyzing specific moments, or creating image-based summaries of the video content.

user $ffmpeg -i my-demo-video_cropped.mp4 -r 15/1 pic%03d.png

Create video from frames

This command creates a video file from a sequence of images. It reads a series of images (pic.%04d.png) using the "image2" demuxer and combines them into a video file (out.mp4) using a frame rate of 15 frames per second (-r 15) and a video bitrate of 8Mbps (-b:v 8M). This command allows users to convert a collection of images into a video with customizable settings such as frame rate and video quality.

user $ffmpeg -f image2 -r 15 -i pic.%04d.png -r 15 -b:v 8M out.mp4

Convert video to 3GP format

This command converts a video file (file.flv) to the 3GP format with specific video and audio settings (-r 15, -b 128k, -s qcif, -acodec amr_nb, -ar 8000, -ac 1, -ab 13). The resulting output file is out.3gp. The specified settings optimize the video for mobile devices, ensuring compatibility and efficient storage utilization.

user $ffmpeg -i file.flv -r 15 -b 128k -s qcif -acodec amr_nb -ar 8000 -ac 1 -ab 13 -f 3gp -y out.3gp

Capture screen video using FFmpeg

This command captures the screen video using x11grab and the dimensions of the screen obtained from xwininfo. The captured video is saved as /tmp/out.mpg. This command is useful for recording desktop activities, creating video tutorials, or capturing any content displayed on the screen:

user $ffmpeg -f x11grab -s $(xdpyinfo | grep 'dimensions:'|awk '{print $2}') -r 25 -i :0.0 -sameq /tmp/out.mpg > ~/howto/capture_screen_video_ffmpeg

With system sound plus mic (converted to mono with "amerge"), for the right display, h264 hardware encoding:

FILE grab.sh
ffmpeg -vaapi_device /dev/dri/renderD128 -f x11grab -video_size 1920x1200 -i :0.0+2566,720 \
	-f pulse -i alsa_output.pci-0000_00_1b.0.analog-stereo.monitor \

FLAC is a lossless audio format that retains the original audio quality while achieving significant compression.

user $ffmpeg -loglevel 0 -y -i audio.mp3 -f sox - | sox -p -V -S -b24 -t audio.flac gain -3 rate -va 7056000 rate -v 48k

Extract audio from FLV video

This command extracts the audio stream from an FLV video file (<filename>.flv) and saves it as an MP3 file (<filename>.mp3). This is useful when you want to separate the audio track from a video file and work with it independently.

user $ffmpeg -i <filename>.flv -vn <filename>.mp3

Trim audio file

This command trims an audio file (input.mp3) by specifying the start time (00:00:30) and duration (00:02:58). The resulting trimmed audio is saved as output.mp3 without any re-encoding. Trimming audio files allows users to extract specific sections or segments of interest.

user $ffmpeg -ss 00:00:30 -t 00:02:58 -i input.mp3 -acodec copy output.mp3

Extract audio from video file and keep the same format

This command extracts the audio stream from a video file (file.ext) and saves it as a separate audio file (out.ext) without any re-encoding. The resulting audio file will have the same format as the input video file. This is useful when you want to extract the audio track from a video file while preserving its original format.

user $ffmpeg -i file.ext -acodec copy -vn out.ext

Extract audio from video and convert to MP3

This command extracts the audio stream from a video file (input.m4a) and converts it to MP3 format using the libmp3lame codec with a bitrate of 128k (-acodec libmp3lame -ab 128k). The resulting audio file is saved as output.mp3. Converting audio from a video to MP3 allows users to extract the audio track in a widely supported format.

user $ffmpeg -i input.m4a -acodec libmp3lame -ab 128k output.mp3

Extract audio and video streams and combine them

This command extracts the audio stream from a source audio file (source_audio.mp3) and the video stream from a source video file (source_video.m2v). The audio stream is offset by 10.2 seconds (-itsoffset 00:00:10.2) and combined with the video stream to create a target video file (target_video.flv). Combining audio and video streams allows users to synchronize them and create a single multimedia file.

user $ffmpeg -i source_audio.mp3 -itsoffset 00:00:10.2 -i source_video.m2v -c copy target_video.flv

Combine video and audio files into a single file

This command combines a video file (video.mp4) and an audio file (audio.mp3) into a single video file (mix.mp4). It copies the video stream (-vcodec copy) and audio stream (-acodec copy) without any re-encoding. Combining video and audio files allows users to merge separate media assets into a unified video file.

user $ffmpeg -i video.mp4 -i audio.mp3 -vcodec copy -acodec copy -map 0.0:0 -map 1.0:1 mix.mp4

Image encoding

Convert audio with image to video

This command converts an audio file (music.flac) with an accompanying image (img.jpg) into a video file (o.mkv). The resulting video will have the image displayed throughout its duration, synchronized with the audio. The command utilizes the VP9 video codec (-vcodec vp9) for efficient compression and the audio stream is copied without any conversion (-acodec copy) to maintain the original audio quality.

user $ffmpeg -r 1 -loop 1 -i img.jpg -i music.flac -shortest -acodec copy -vcodec vp9 o.mkv

Please note that the frame rate (FPS) of the resulting video can be modified by adjusting the "-r" parameter. A lower frame rate, such as "-r 0.1", can lead to faster encoding and a smaller file size. However, it's important to note that using such low frame rates may result in compatibility issues with certain platforms, like PeerTube. For optimal compatibility, using "-r 1" or higher is recommended, although it may slightly impact the quality of the displayed image. Experimenting with values like "-r 2" can strike a balance between quality and encoding speed.

Create a slideshow with background music

This command creates a slideshow from a series of images (img%03d.jpg) and adds background music from an audio file (music.mp3). The output video file (slideshow.mp4) uses the H.264 video codec and AAC audio codec. The frame rate is set to 24 frames per second (-r 24) and the audio bitrate is set to 128 kbps (-b:a 128k). This command is useful for creating a slideshow presentation with synchronized music.
