# As of 1 this script works to download and install just about every codec needed for video as well as a bunch of extra stuff I use. Let a few community members read through it before you run it. It will auto download the source for just about any codec and compile it. How can I find out the archive from which a package originated? My packages have all "Origin: Ubuntu" and medibuntu has been added to but I removed it some time ago. Now I understand that my ffmpeg is not compiled with the amr codec. Then in ffmpeg -formats, under the Codecs section (I'm talking about repo version here), you should see:ĭEA libopencore_amrnb OpenCORE Adaptive Multi-Rate (AMR) Narrow-Bandĭ A libopencore_amrwb OpenCORE Adaptive Multi-Rate (AMR) Wide-Band To get AMR decoding working you have two main options: you can compile ffmpeg (see option A in above link), or, if you want to use repository ffmpeg, use the libavcodec-extra-52 package from Medibuntu (see option C in above link). The second command is attempting to re-encode, but it fails because you do not have an AMR decoder. You could probably do this with a variety of output formats despite them being not a valid or supported combination. In the first command ffmpeg is blindly copying the audio from the input and dumping it into the output. Why is "ffmpeg -i in.amr -acodec copy out.wav" working while "ffmpeg -i in.amr out.wav" is not?
Yes, if you use ffmpeg from the repository. Yes, but only if you follow option A or C from HOWTO: Easily enable MP3, MPEG4, AAC, and other restricted encoders in FFmpeg (). Now you can confirm your system is running FFmpeg 4:įfmpeg -V ffmpeg version 4.3.2-0york0~16.Is "ffmpeg -i in.amr out.wav" supposed to work? (the y flag is to save having to confirm a bunch of things.) Sudo ln -s /usr/bin/python3.6 /usr/bin/python3įinally, install the latest version of FFmpeg: You will need to update the symbolic link for python3 to the correct Python version on your system like this (for me it is 3.6 but it may be different on your system): Sudo: unable to execute /usr/bin/add-apt-repository: No such file or directory Sudo add-apt-repository ppa:jonathonf/ffmpeg-4 The first step is to add the jonathonf/ffmpeg-4 repository using the following command: In this tutorial, we will learn how to install FFmpeg 4 on Ubuntu 16.04 from a PPA (Personal Package Archive). If you try to install FFmpeg using the package manager on Ubuntu 16.04 you will notice that the newest version it will give you is 2.8.11, which is a long way off from the latest version.
