ffmpeg -i video.mp4 -acodec libshine -q:a 0 Check the below given command to understand. To control the quality of the audio output, we have to add the -aq q (-q:a) to set the audio quality ( 0 to 6), 0 being high quality and 6 being low quality. Video:0kB audio:1797kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 0.028368% ffmpeg -i video.mp4 -acodec libshine audio2.mp3 Check the following for better understanding. To achieve that, we will have to set the encoder after the -acodec audio option. In case we didn’t prefer the audio container format or we want to compress it, we simply choose our favorite encoder Based on the quality produced that FFMPEG can use. Note: The greater than or equal to symbol ( >=) is used to represent: better or same quality. We can choose the encoder based on the produced quality by checking the following list: libopus > libvorbis >= libfdk_aac > libmp3lame >= eac3/ac3 > aac > libtwolame > vorbis > mp2 > wmav2/wmav1 The following table list some lossy audio compression formats with their appropriate encoders that FFMPEG can use:

Extracting an Audio Out of a Video File With Re-encodingįFMPEG is able to encode to a wide variety of audio formats. We can also use the -map flag to select all audio streams or to select a specific part of the audio. We achieve this by extracting raw audio (without re-encoding it), or by re-encoding it. There are two common operations and very useful ways so we can extract audio from an input video file. In the examples given in this article, it is assumed that the user has navigated to the working directory to execute the FFMPEG commands. Note: As with any command line interface, the user should specify the path of input or output files depending on their working directories. Follow the below command: ffprobe video.mp4Īfter we’ve checked the media file information, notice that the audio stream format is aac, which will be our container format for the final file Note: We can achieve similar results by using ffprobe which is one of FFMPEG main executable, this command is used for getting the characteristics of media files containers and streams. Let’s type ffmpeg to check the ffmpeg configuration. One final step left is to verify that FFMPEG is actually installed. So now we can use the ffmpeg command in the command line. FFMPEG will get installed onto our system, and also add the ffmpeg binary to the path variable.

To install FFMPEG project, we first go to our terminal, and type the following update command to download package information from all configured sources: sudo apt updateĪfter making sure that the first command got executed correctly, Type the below given command and hit Enter to install the project: sudo apt install ffmpegĪfter executing the preceding command.

That’s exactly what we will be discussing in the next paragraphsīasic FFmepg commands consist of four elements: ffmpeg How to Install FFMPEG This project has a lot of useful features, one of them is extracting audio from video we all have been in that situation when we have some video file, but we only need its audio (for example : a video clip).

FFMPEG is actually a command line utility (CLI) used mainly by software developers and media industry professionals, to perform operations on media files such as format conversion, encoding, resizing, concatenation, and compression. This tool powers many widespread media-based applications, such as: iTunes, Youtube and the famous video player VLC.įFMPEG is a very fast tool used for converting and streaming video and audio, and also used in grabbing from live video or audio sources. One very good example of this description is FFMPEG. In our daily computing life, we make use of software and programs without realizing that we are using a particular different program used by our main program.
