I have two mp4 files. One of them was given to me and plays well under mediawiki (using the MediawikiPlayer extension). The other I created from a WMV file and it does not play. When I look at the two files through the eyes of ffprobe, they appear to be very different. The working file returns this:

Metadata:

  minor_version   : 0

The non-working produces this:

What ffmpeg options do I need to supply to convert my wmv file to an mp4 file like the first of those listed here (the working one)?

Update: 2015-10-23, here is the full output from ffmpeg for the non-working file:

    You have to show your `ffmpeg` command and the **complete** console output. It will have the info necessary for an answer. I have an idea of what the issue may be, but without additional info I won't make an uneducated guess. – llogan Oct 19 '15 at 17:51

    The problem is the file that works was not produced by me, so I don't have the ffmpeg command or output. I don't remember what I used for my file, but that file doesn't work, so it's not going to be all that helpful, I'd think. – user1207446 Oct 21 '15 at 13:02
  • Then at least show the complete console output of: `ffmpeg -i nonworking.mp4`. – llogan Oct 21 '15 at 16:14
  • The output is posted above, except the information on the ffmpeg version. – user1207446 Oct 22 '15 at 17:21
  • ffmpeg version N-71329-g235589e Copyright (c) 2000-2015 the FFmpeg developers built with gcc 4.9.2 (GCC) – user1207446 Oct 22 '15 at 17:22
  • There is more missing than just the version. Please add the info to the question instead of attempting to cram it all into a comment. – llogan Oct 22 '15 at 17:25
  • I found a tool, the Miro Video Converter (http://www.mirovideoconverter.com/) that produces mp4 files that work, so there is no longer any urgency. Also, I believe at least a big part of the issue has to do with 'MPEG-4 Part 2' ('Simple Profile') and 'MPEG-4 Part 10' (H.264/AVC). So, perhaps the question I want to ask is: How to I use ffmpeg to produce an h.264/avc mp4 file? The answer to that seems to be here: https://trac.ffmpeg.org/wiki/Encode/H.264 – user1207446 Oct 22 '15 at 17:35
  • Once again, the missing console output info will provide the details necessary to provide the answer. – llogan Oct 22 '15 at 17:47
  • I have added the full console output to my initial post above. – user1207446 Oct 23 '15 at 17:58
