Similar actions can be added to extract sound from other types of video and, of course, for other very different purposes. There are other options, but these look sufficient for the purpose of my question. Under Mimetypes tab, enter the filters for the type of files in the context menu of which you want to see the command - in this case: video/mp4 and video/flv. Under Execution tab there are options to select depending on what you want to see during and after the action (open terminal, report).
Check - 'Display action in selection context menu'.īash -c 'ffmpeg -i "$0" -map 0:1 -c:a copy "$".m4a' %f. I will provide an example for extracting audio (aac in m4a container) from flv and mp4 video files.ĭefine a new action, give it a name, maybe an icon too. Then install Nautilus-Actions Configuration Tool and open it. Example Select Convert/Save from File pulldownīetter than trying to add context menu commands to the minimalist Pantheon-Files of Elementary OS or to use other media applications to extract sound from video, I guess the most simple is just to install Nautilus (it is not at all problematic in eOS, contrary to Thunar, which comes with the whole Xfce environment).
You can use VLC and it's Convert/Stream feature to do this. Stream #0.0: Audio: aac, 32000 Hz, stereo, s16, 45 kb/sĪt least one output file must be specified You can also use ffmpeg to confirm the file format: $ ffmpeg -i sample_mpeg4.aac Video:0kB audio:30kB global headers:0kB muxing overhead 3.594943%
You can extract the AAC audio frpm the mP4 file. If you go to QuickTime: Sample files, you can download this sample file, sample_mpeg4.mp4. If you're willing to forgo using a GUI you can use ffmpeg fairly easily to do this.
