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. |

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.aviExtract 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.pngCreate 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.mp4Convert 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.

This section provides advanced FFmpeg commands for audio encoding, enabling users to manipulate audio files with various settings and configurations.
Convert audio to MP3
This command converts an audio file (input.flv) to the MP3 format using the specified audio quality (2). The resulting output file will be named output.mp3. MP3 is a widely supported audio format known for its efficient compression and compatibility.
user $ffmpeg -i input.flv -aq 2 output.mp3Convert audio to FLAC
This command converts an audio file (audio.mp3) to the FLAC format using SoX. It applies various effects, such as gain adjustment and sample rate conversion, and saves the output as a FLAC file (audio.flac). 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 48kExtract 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>.mp3Trim 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.mp3Extract 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.extExtract 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.mp3Extract 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.flvCombine 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.mp4Image 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.mkvPlease 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.
user $ffmpeg -framerate 1/5 -i img=%03d.jpg -i music.mp3 -c:v libx264 -c:a aac -r 24 -b:a 128k slideshow.mp4Resize an image
This command resizes an image (input.jpg) to a width of 800 pixels while preserving the aspect ratio. The resulting image is saved as output.jpg. This command is useful for resizing images to fit specific dimensions or aspect ratios.
user $ffmpeg -i input.jpg -vf "scale=800:-1" output.jpgCrop an image
This command crops an image (input.jpg) to a specified width and height (500x300) starting from the top-left corner. The resulting image is saved as output.jpg. This command is useful for removing unwanted parts or focusing on specific areas of an image.
user $ffmpeg -i input.jpg -vf "crop=500:300" output.jpgAdd a border to an image
This command adds a black border to an image (input.jpg) with a thickness of 10 pixels. The resulting image is saved as output.jpg. This command is useful for creating a visual separation or frame around an image.
user $ffmpeg -i input.jpg -vf "pad=width=iw+20:height=ih+20:color=black" output.jpgConvert an image to grayscale
