I understand that this is SIMILAR to questions asked before and using those posts I have actually got the file process going however when it finishes (with out errors mind you) the .mp4 is a 0KB file and when opened using movie player it says stream contains no data.

code used to convert:

avconv -i movie.mkv -map 0 -strict experimental movie.mp4


avconv -i movie.mkv -map 0 movie.mp4


avconv -i movie.mkv -codec copy movie.mp4


avconv -i movie.mkv -c:v copy -c:a libfaac movie.mp4

they all end with this.

video:400835kB audio:85478kB global headers:0kB muxing overhead -100.000000%

Try installing the Ubuntu restricted extras package. You may be missing some of the required codecs. You can install through the software center as shown below:SoftCenter-Restricted-extras

Or you can install via the command line with sudo apt-get install ubuntu-restricted-extras

  • Thanks for this! I'll give it a try next time I try to convert something (honestly might be a while I've since I've changed jobs.) – p38sheep Nov 5 '15 at 18:57
  • Your welcome! I hope it helps you or someone else with similar issues. – Elder Geek Nov 5 '15 at 19:05
