mp4 video file container.ĭepending on the workload we give it, ffmpeg might need a powerful computer as the transcoding tasks are usually CPU intensive. Here ffmpeg is taking a stream in HLS format, processing it and converting its video stream to the h265 specification, its audio to the opus specification and saving it to a. ffmpeg -i -c:v libx265 -c:a opus stream.mp4 Specifying a URL of a stream on the internet with the -i option, ffmpeg can stream it and process it. We can also stream a video from the internet, transcode it and save it on our computer with FFmpeg. In our example we are transcoding the video stream with the libx265 encoder and the audio stream with the aac encoder. The -c:v option is to specify the video encoder to use and the -c:a option is to specify the audio encoder to use. ffmpeg -i video.mp4 -c:v libx265 -c:a aac video.mp4 To transcode a video with a specific encoder we run the following command. We can run the first one to look at all the encoders and the second one to look at all the decoders. We can take a look at all of them with the following commands. ffmpeg -i video.mp4 video.mkv Transcoding With a Specific EncoderįFmpeg has a long list of encoders and transcoders to use. If we want to transcode the video instead of simply copying it we use the same command minus the -c copy option. mkv video file by simply copying the video data stream and just changing the container. This command simply converts the video from an. ffmpeg always needs to specify a file to work with, we always specify the working file with the -i option. To do this we run the ffmpeg command on the Ubuntu terminal command line. webm and many others including from audio to audio formats, such as. We can easily convert a video type to another with FFmpeg. FFmpeg Usage Examples Convert Videos with FFmpeg #INSTALL FFMPEG UBUNTU CLEAR UPDATE#When there’s a new version available you can update with Ubuntu’s Software Update tool. The guide is supposed to make compiling easy since the ideas is that the user must only successfully copy and paste, but compiling is not for everyone and results may vary.Output ffmpeg version 4.4-6ubuntu5 Copyright (c) 2000-2021 the FFmpeg developersīuilt with gcc 11 (Ubuntu 11.2.0-7ubuntu1)Ĭonfiguration: -prefix=/usr -extra-version=6ubuntu5 -toolchain=hardened -libdir=/usr/lib/x86_64-linux-gnu -incdir=/usr/include/x86_64-linux-gnu -arch=amd64 -enable-gpl -disable-stripping -enable-gnutls -enable-ladspa -enable-libaom -enable-libass -enable-libbluray -enable-libbs2b -enable-libcaca -enable-libcdio -enable-libcodec2 -enable-libdav1d -enable-libflite -enable-libfontconfig -enable-libfreetype -enable-libfribidi -enable-libgme -enable-libgsm -enable-libjack -enable-libmp3lame -enable-libmysofa -enable-libopenjpeg -enable-libopenmpt -enable-libopus -enable-libpulse -enable-librabbitmq -enable-librubberband -enable-libshine -enable-libsnappy -enable-libsoxr -enable-libspeex -enable-libsrt -enable-libssh -enable-libtheora -enable-libtwolame -enable-libvidstab -enable-libvorbis -enable-libvpx -enable-libwebp -enable-libx265 -enable-libxml2 -enable-libxvid -enable-libzimg -enable-libzmq -enable-libzvbi -enable-lv2 -enable-omx -enable-openal -enable-opencl -enable-opengl -enable-sdl2 -enable-pocketsphinx -enable-librsvg -enable-libmfx -enable-libdc1394 -enable-libdrm -enable-libiec61883 -enable-nvenc -enable-chromaprint -enable-frei0r -enable-libx264 -enable-shared If this is the case then try: cd ~/ffmpeg #INSTALL FFMPEG UBUNTU CLEAR INSTALL#This is to avoid conflicts with packages from the repository, but I'm guessing you did install to the system with sudo make install without using checkinstall therefore it is not integrated in the package management system. The guide does not install ffmpeg to the system. However, seeing your other recent ffmpeg question it appears that you did not follow the guide or did not follow it correctly so this may not work for you.
