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.
