how to combine an audio track and video file?
- Inicie sesión o regístrese para enviar comentarios
If I have separate audio and video files, can I combine them into one file? I don't want to convert/transcode anything ... I don't want to lose quality in any conversion. I'd just like to join two files together.
The VLC ppa from https://launchpad.net/~djcj/+archive/ubuntu/vlc-stable also has the latest ffmpeg as well. You may want to search on how to use ffmeg to put codecs into a container.
What are the audio and video codecs? The container format may be dependant on what they are.
The repository above contains the non-free FDK AAC (the new FAAC!) library, which is installed alongside FFmpeg/VLC, and cannot be removed due to the fact that it was manually enabled before compilation. Also, the maintainer obviously doesn't care too much about free software.
The latest FFmpeg can be downloaded here:

I am a translator!
sudo apt-get install openshot
you can also do this with the preinstalled video editor in trisquel : pitivi. I personnaly have some problems using it and find kdenlive easier to use.
Maybe you won't have the desired quality when exporting the file. You can also edit audio and video in ardour 3, in wich you may find all the needed options about audio quality.
Try:
ffmpeg -i /path/to/one/file -i /path/to/another/file -acodec copy -vcodec copy /path/to/output/file
Thanks a lot guys, I will give this a try. I'll try ffmpeg first.
Hi again. Trisquel 7 doesn't have ffmpeg. It has avconv; does anyone know how to use avconv in the way that jxself described how to use ffmpeg?
It should be the same; just replace ffmpeg with avconv and run it.
I tried it and got the following output. Btw, I see t3g's post; I might give that a try too after I learn how to add a ppa.

I use the Matroska tools (install the mkvtoolnix-gui package for the GUI
app or the mkvtoolnix package for the command line tools) for this job.
Matroska is a capable container format that would also let you mux in
subtitles in multiple languages, chapters, alternate audio tracks, and more.
