Useful FFmpeg Commands

Fmpeg is an extremely powerful and versatile command line tool for converting audio and video files. It is free and available for Windows, Mac and Linux machines. Whether you want to join two video files, extract the audio component from a video file, convert your video into an animated GIF, FFmpeg can do it all and even more.

USEFUL FFMPEG COMMANDS

FFmpeg supports all popular audio and video formats. Or you can running the command ./ffmpeg -formats to get a list of every format that is supported by your FFmpeg installation. If you are just getting started, here are some commands that will give you good idea of the capabilities of this tool.

1. CUT VIDEO FILE INTO A SMALLER CLIP

You can use the time offset parameter (-ss) to specify the start time stamp in HH:MM:SS.ms format while the -t parameter is for specifying the actual duration of the clip in seconds.

ffmpeg -i input.mp4 -ss 00:00:50.0 -codec copy -t 20 output.mp4

2. SPLIT A VIDEO INTO MULTIPLE PARTS

If you want to split a large video into multiple smaller clips without re-encoding, ffmpeg can help. This command will split the source video into 2 parts – one ending at 50s from the start and the other beginning at 50s and ending at the end of the input video.

ffmpeg -i video.mp4 -t 00:00:50 -c copy small-1.mp4 -ss 00:00:50 -codec copy small-2.mp4

3. CONVERT VIDEO FROM ONE FORMAT TO ANOTHER

You can use the -vcodec parameter to specify the encoding format to be used for the output video. Encoding a video takes time but you can speed up the process by forcing a preset though it would degrade the quality of the output video.

ffmpeg -i youtube.flv -c:v libx264 filename.mp4
ffmpeg -i video.wmv -c:v libx264 -preset ultrafast video.mp4

4. JOIN (CONCATENATE) VIDEO FILES

If you have multiple audio or video files encoded with the same codecs, you can join them into a single file using FFmpeg. Create a input file with a list of all source files that you wish to concatenate and then run this command.

ffmpeg -f concat -i file-list.txt -c copy output.mp4

5. MUTE A VIDEO (REMOVE THE AUDIO COMPONENT)

Use the -an parameter to disable the audio portion of a video stream.

ffmpeg -i video.mp4 -an mute-video.mp4

6. EXTRACT THE AUDIO FROM VIDEO

The -vn switch extracts the audio portion from a video and we are using the -ab switch to save the audio as a 256kbps MP3 audio file.

ffmpeg -i video.mp4 -vn -ab 256 audio.mp3

7. CONVERT A VIDEO INTO ANIMATED GIF

FFmpeg is an excellent tool for converting videos into animated GIFs and the quality isn’t bad either. Use the scale filter to specify the width of the GIF, the -t parameter specific the duration while -r specifies the frame rate (fps).

ffmpeg -i video.mp4 -vf scale=500:-1 -t 10 -r 10 image.gif

8. EXTRACT IMAGE FRAMES FROM A VIDEO

This command will extract the video frame at the 15s mark and saves it as a 800px wide JPEG image. You can also use the -s switch (like -s 400×300) to specify the exact dimensions of the image file though it will probably create a stretched image if the image size doesn’t follow the aspect ratio of the original video file.

ffmpeg -ss 00:00:15 -i video.mp4 -vf scale=800:-1 -vframes 1 image.jpg

9. CONVERT VIDEO INTO IMAGES

You can use FFmpeg to automatically extract image frames from a video every ‘n’ seconds and the images are saved in a sequence. This command saves image frame after every 4 seconds.

ffmpeg -i movie.mp4 -r 0.25 frames_%04d.png

10. MERGE AN AUDIO AND VIDEO FILE

You can also specify the -shortest switch to finish the encoding when the shortest clip ends.

ffmpeg -i video.mp4 -i audio.mp3 -c:v copy -c:a aac -strict experimental output.mp4
ffmpeg -i video.mp4 -i audio.mp3 -c:v copy -c:a aac -strict experimental -shortest output.mp4

11. RESIZE A VIDEO

Use the size (-s) switch with ffmpeg to resize a video while maintaining the aspect ratio.

ffmpeg -i input.mp4 -s 480x320 -c:a copy output.mp4

12. CREATE VIDEO SLIDESHOW FROM IMAGES

This command creates a video slideshow using a series of images that are named as img001.png, img002.png, etc. Each image will have a duration of 5 seconds (-r 1/5).

ffmpeg -r 1/5 -i img%03d.png -c:v libx264 -r 30 -pix_fmt yuv420p slideshow.mp4

13. ADD A POSTER IMAGE TO AUDIO

You can add a cover image to an audio file and the length of the output video will be the same as that of the input audio stream. This may come handy for uploading MP3s to YouTube.

ffmpeg -loop 1 -i image.jpg -i audio.mp3 -c:v libx264 -c:a aac -strict experimental -b:a 192k -shortest output.mp4

14. CONVERT A SINGLE IMAGE INTO A VIDEO

Use the -t parameter to specify the duration of the video.

ffmpeg -loop 1 -i image.png -c:v libx264 -t 30 -pix_fmt yuv420p video.mp4

15. ADD SUBTITLES TO A MOVIE

This will take the subtitles from the .srt file. FFmpeg can decode most common subtitle formats.

ffmpeg -i movie.mp4 -i subtitles.srt -map 0 -map 1 -c copy -c:v libx264 -crf 23 -preset veryfast output.mkv

16. CROP AN AUDIO FILE

This will create a 30 second audio file starting at 90 seconds from the original audio file without transcoding.

ffmpeg -ss 00:01:30 -t 30 -acodec copy -i inputfile.mp3 outputfile.mp3

17. CHANGE THE AUDIO VOLUME

You can use the volume filter to alter the volume of a media file using FFmpeg. This command will half the volume of the audio file.

ffmpeg -i input.wav -af 'volume=0.5' output.wav

18. ROTATE A VIDEO

This command will rotate a video clip 90° clockwise. You can set transpose to 2 to rotate the video 90° anti-clockwise.

ffmpeg -i input.mp4 -filter:v 'transpose=1' rotated-video.mp4

This will rotate the video 180° counter-clockwise.

ffmpeg -i input.mp4 -filter:v 'transpose=2,transpose=2' rotated-video.mp4

19. SPEED UP OR SLOW DOWN THE VIDEO

You can change the speed of your video using the setpts (set presentation time stamp) filter of FFmpeg. This command will make the video 8x (1/8) faster or use setpts=4*PTS to make the video 4x slower.

ffmpeg -i input.mp4 -filter:v "setpts=0.125*PTS" output.mp4

20. SPEED UP OR SLOW DOWN THE AUDIO

For changing the speed of audio, use the atempo audio filter. This command will double the speed of audio. You can use any value between 0.5 and 2.0 for audio.

ffmpeg -i input.mkv -filter:a "atempo=2.0" -vn output.mkv

Stack Exchange has a good overview to get you started with FFmpeg. You should also check out the official documentation at ffmpeg.org or the wiki at trac.ffmpeg.org to know about all the possible things you can do with FFmpeg.

How to install FFmpeg and ffmpeg-php on CentOS Easily

FFmpeg is an amazing collection of open-source tools that can record and stream video and audio. However, it can also transcode video and audio (convert the files to different formats), and that is what has me so excited. There’s also a great PHP package called ffmpeg-phpthat allows for easy use of FFmpeg from inside PHP scripts. Today, I’m going to see if I can’t help you get both of these set up on your system.

Admittedly, it’s been a while since I’ve tried to install FFmpeg, about two years. I recently thought up some ideas on how I’d like to use FFmpeg, so I thought it was time to give it a try yet again. Today, I’m proud to say that installing FFmpeg is so much easier to install compared to the past, that I dare say it’s simple.

Here is my experience with installing FFmpeg on my server and how to fix the pitfalls that I encountered.

Preface

Note that I did all the following steps on a CentOS server. The specific version is CentOS x64 6.7.

These instructions can work for other distros with little or no modifications, but some distros will be completely different. For example, theDAG RPM Repository that I’m using (more info below) has support for the following distros: Red Hat Enterprise Linux, Fedora Core, Yellow Dog Linux, Aurora Linux, CentOS, Scientific Linux (they really need to get a verified SSL cert), TaoLinux, WhiteBox Linux, Lineox, andBLAG. Other distros will need to use a different repository.

If you successfully get FFmpeg running on another distro, please comment your changes here and I’ll update the post (and make sure you get credit of course).

Also note that I experienced some bumps in the road while installing everything. While many of you may not experience these issues, I found it important to document these problems and how I fixed them in case you encounter them.

Preparing

The first thing that you need to do is set up the DAG repository. This repository is an actively-maintained repository that provides a staggering number of packages with current or near current builds. Adding this repository is a great way to run the latest offerings of many packages.

Adding the DAG repository is simple. I’m using yum, so I did the following to add the repository:

  1. Create and open a new file called /etc/yum.repos.d/dag.repo. I ran “vi /etc/yum.repos.d/dag.repo“.
  2. Add the following text to the file:
    [dag]
    name=DAG RPM Repository
    baseurl=http://apt.sw.be/redhat/el$releasever/en/$basearch/dag
    gpgcheck=1
    enabled=1
  3. Finally, save and close the file.

In order to successfully use the DAG repository with tools such as yum, you need to add DAG’s GPG key. Failure to do so will result in an error like the following:

warning: rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY, key ID 6b8d79e6
Public key for faac.x86_64.1.26-1.el5.rf.rpm is not installed

In order to add the GPG key for DAG, run the following:

rpm --import http://apt.sw.be/RPM-GPG-KEY.dag.txt

The DAG: Frequently Asked Questions page has additional instructions on how to get the repository loaded and working on your distro.

Now that DAG is setup, it’s a good idea to update all your packages.

yum update

Depending on the packages you currently have installed, this could potentially upgrade, install, or replace numerous packages that may or may not be very important to you. Make sure you carefully look through that list and do any necessary preparations before telling yum that it can go ahead.

For example, yum told me that it was going to replace my current MySQL interface library for Perl with a new one. I added to my check list a note to verify that my Perl code functioned correctly after the install.

I ran into another hitch when I told yum to go ahead with the update. It informed me that my current version of Subversion conflicted with the new version it wanted to install. When this happens, you need to remove the old package before proceeding. This time, I made backups of all of my repositories and my /etc/sysconfig/svnserve file before proceeding just in case. I then removed Subversion “yum remove subversion“, ran the update process “yum update“, and installed Subversion again “yum install subversion“.

Installing – FFmpeg

Now you are ready to install FFmpeg with yum. I wanted to install all the available FFmpeg packages, so I first asked yum what was available.

yum search ffmpeg

Searching through the results, I found that three packages need to be installed: ffmpeg, ffmpeg-devel, and ffmpeg-libpostproc.

yum install ffmpeg ffmpeg-devel ffmpeg-libpostproc

Note: If you install ffmpeg-libpostproc, the entire FFmpeg software library changes from the LGPL license to the GPL license.

After a couple of minutes, the packages and the packages that they depend on were installed.

I simply ran “ffmpeg” from the command line, and I took the lack of threatening error or warning messages as a good sign that things were working.

Preparing for ffmpeg-php

I often work with programs through command line calls in code, but I wanted something more robust this time, so I looked around and foundffmpeg-php. Based on the API, it looks to be a great tool to interface PHP and FFmpeg.

There are four things that are required to successfully install and run ffmpeg-php; they are:

  • ffmpeg-0.4.9_pre1 or higher
  • php-4.3.0 or higher
  • gd-2.0 or higher
  • php-devel

PHP and FFmpeg should be good to go since at the time of this writing, DAG has PHP version 5.1.6 and FFmpeg version 0.4.9. GD and php-devel can be easily installed by running the following yum command:

yum install php-gd php-devel

In case you are wondering what php-devel is for, it installs the phpize program which is used to install ffmpeg-php.

Installing ffmpeg-php

Now we are ready to install ffmpeg-php. This can be done in six easy steps:

  1. Download the latest ffmpeg-php release
  2. Extract the archive:
    tar -xjf ffmpeg-php-X.x.x.tbz2
  3. cd ffmpeg-php-X.x.x/
  4. phpize
  5. ./configure && make
  6. sudo make install

Finishing Thoughts

This may seem like a lot of work when I earlier described this process as “simple,” but trust me that this is a thousand times easier than when I first tried installing FFmpeg. I think I spent three hours working on installing FFmpeg just to find out that it didn’t work the first time I tried.

Time and time again, package management has proven to be an extremely powerful tool. While I know the value of manually configuring and compiling code, the ease of simply using a package manager can reduce the time needed to install and manage software from hours or days to minutes.

I’m glad to see that FFmpeg has benefited from the use of these package managers and great repositories like the DAG RPM Repository.

Install FFMpeg from ATRPMS Repository:

yum -y install ffmpeg ffmpeg-devel

How to check if FFMPEG is working?

Verify the ffmpeg version:

ffmpeg -version

Check the supported formats:

ffmpeg -formats

Test converting videos. Here’s an example from mp4 to h264:

cd /usr/local/src
wget https://archive.org/download/WoodstockFestivalTrailer/Woodstock_Festival_Trailer.avi
ffmpeg -i Woodstock_Festival_Trailer.avi -vcodec libx264 Woodstock_Festival_Trailer-H264.avi

After done, you should see the new H264 file:

-rw-r--r-- 1 root root 20M May 4 2006 Woodstock_Festival_Trailer.avi
-rw-r--r-- 1 root root 15M Jan 30 10:01 Woodstock_Festival_Trailer-H264.avi

How can I work with ffmpeg using PHP?

Simple.  Just install php-ffmpeg extension. First, install REMI repo in order to get your php-ffmpeg package as below:

Let’s download the RPM file for CentOS 5.x and CentOS 6.x:

EPEL repo for  Centos 5.x

wget http://dl.fedoraproject.org/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm
rpm -Uvh epel-release-5*.rpm

EPEL repo for Centos 6.x

wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
rpm -Uvh  epel-release-6*.rpm

EPEL repo for Centos 7.x

wget http://download.fedoraproject.org/pub/epel/beta/7/x86_64/epel-release-7-0.2.noarch.rpm
rpm -Uvh  epel-release-6*.rpm

That command will install the EPEL repo inside your /etc/yum.repos.d directory.

then

Manually, install FFmpeg-Php
        cd /usr/local/src
        wget http://sourceforge.net/projects/ffmpeg-php/files/ffmpeg-php/0.6.0/ffmpeg-php-0.6.0.tbz2
        tar jxvf ffmpeg-php-0.6.0.tbz2
        cd ffmpeg-php-0.6.0
        phpize
        ./configure
        make
If you get (error make: *** [ffmpeg_frame.lo] Error 1) do this commands.
sed -i 's/PIX_FMT_RGBA32/PIX_FMT_RGB32/g' ffmpeg_frame.c
 OR
 vi ffmpeg_frame.c
 :%s/PIX_FMT_RGBA32/PIX_FMT_RGB32
:wq
Then rerun "./configure && make" and if all went fine make install make install If no error skil to step 5. Step 5. Now adding to php.ini echo 'extension=ffmpeg.so' >> /usr/local/lib/php.ini Step 6. Now test php with ffmpeg php -r 'phpinfo();' | grep ffmpeg

-i | grep ffmpeg -i

/etc/php.d/ffmpeg.ini,
ffmpeg
ffmpeg-php version => 0.7.0
ffmpeg-php built on => Jan  1 2013 09:50:55
ffmpeg-php gd support  => enabled
ffmpeg libavcodec version => Lavc53.61.100
ffmpeg libavcodec license => GPL version 3 or later
ffmpeg libavformat version => Lavf53.32.100
ffmpeg libavformat license => GPL version 3 or later
ffmpeg swscaler version => SwS2.1.100
ffmpeg swscaler license => GPL version 3 or later

When you run command ./configure if you get error: configure: error: ffmpeg headers not found. Make sure ffmpeg is compiled as shared libraries using the –enable-shared option. Check some library with command:

rpm -ql ffmpeg-devel

In On CentOS 6/7 with nux-dextop installed ffmpeg-devel

locate avio.h avformat.h avcodec.h
/usr/include/ffmpeg/libavcodec/avcodec.h
/usr/include/ffmpeg/libavfilter/avcodec.h
/usr/include/ffmpeg/libavformat/avformat.h
/usr/include/ffmpeg/libavformat/avio.h
/usr/share/doc/ffmpeg/libavcodec.html
/usr/share/doc/ffmpeg/libavformat.html

Now  do command:

[root@centos ffmpeg-php-0.6.0]# strace -f -o /ffmpeg-strace ./configure --with-php-config=/usr/bin/php-config --with-ffmpeg=/usr --includedir=/usr/include/ffmpeg

Then:

cat /ffmpeg-strace | egrep 'avio.h|avformat.h|avcodec.h'

Looks like ffmpeg-devel installed headers at

  • /usr/include/ffmpeg/libavcodec/avcodec.h
  • /usr/include/ffmpeg/libavfilter/avcodec.h
  • /usr/include/ffmpeg/libavformat/libavformat.h
  • /usr/include/ffmpeg/libavformat/avio.h

Problem is specific to avcodec.h, avformat.h, avio.h and swscale.h – so what about symlinking them

ln -s /usr/include/ffmpeg/libavcodec/avcodec.h /usr/include/ffmpeg/avcodec.h
ln -s /usr/include/ffmpeg/libavformat/libavformat.h /usr/include/ffmpeg/libavformat.h
ln -s /usr/include/ffmpeg/libavformat/libavformat.h /usr/include/ffmpeg/libavformat.h
ln -s /usr/include/ffmpeg/libswscale/swscale.h /usr/include/ffmpeg/swscale.h

Then configure and make again:

./configure && make

How to Install FFMPEG Auto Installer on CentOS

Seeing as FFMPEG Auto Installer do not give clear instructions on how to install their packages I have produced a easy guide which hopefully should be of some use to server admins and novices alike.

Firstly SSH into your server.

Now run the following commands:

mkdir ~/ffmpeg-packages 
cd ~/ffmpeg-packages 
wget http://mirror.ffmpeginstaller.com/old/scripts/ffmpeg7/ffmpeginstaller.8.0.tar.gz 
tar -xvzf ffmpeginstaller.8.0.tar.gz
cd ffmpeginstaller.8.0

Im using version ffmpeginstaller.8.0 for this installation, make sure you edit your command to coincide with the current package.

Next run the install command:

./install.sh

That’s it.
