Situation: unable to view .m4s files in Ubuntu 16.04
Motivation: I recorded videos by Chrome's addon, GetThemAll, and get a result of 10 .mp4 videos
Unsuccessful viewers/converters: vlc, http://online-audio-converter.com/, not .m4a files as described here

Files in using GetThemAll, ls -l directory and file *. You see no pieces of information about any init file

$ ls -la
total 25148

I do unsuccessfully and try to open the .mp4 file in VLC without playing

# andrew.46
$ cat $(ls -x *.m4s) > testing.mp4

$ file testing.mp4 
testing.mp4: data

  • Output of ls -x *.m4s

    segment-10.m4s.m4s  segment-1.m4s(1).m4s  segment-1.m4s.m4s
segment-3.m4s.m4s   segment-4.m4s.m4s     segment-5.m4s.m4s

    When you produced the videos you should have had one file with 'init' in the filename and then several more with sequential numbers. Can you give the results of the ls command in the directory containing your .m4s files?

    You seem to be missing the init file although there is an oddly named file: segment-1(1).m4s. Try the following anyway: cat $(ls -x *.m4s) > testing.mp4 and see if this produces a combined video...

  • You are missing a part of your download I suspect. Sorry I could be of no help :(

  • @andrew.46 I found a solution. Please, see the wikipage below. There are many videos in one page, which probably is confusing your proposal. - - They are Vimeo videos so just use the plugin in the browser to download them, made for Vimeo.

    gpac is available through apt-get. You need to enable the "universe" repository.

There are many videos in the site. I think andrew.46's proposal get confused by the fact. I could not find any init file for Vimeo videos. Final solution.

  • Study the source code and see if you can see the video sources coming from some major video provider. My case: Vimeo.
  • Install the extension: Download Vimeo Videos, Premium
  • Go to the site and activate videos; just downlod.

Based mchid's comment answer, you can use gpac
