Various mp4 failed to play.
Firefox giving:
the video can't be played because the file is corrupt.

Analysis of the mp4 file shows that the issue occurs when the mdat track is found before the moof one.

Example:
http://people.mozilla.org/~jyavenard/mediatest/BreakVDA.mp4

The file mentioned in bug #906422 also exhibit the same problem when using libstagefright

Same with some of the files mentioned in Bug #987894

Note: I believe we could completely remove the handling of mdat.

ignore mdat unless we've already found a media track

-----------------------------------------------------------------

The patch description is wrong. We used to stop parsing when we reach the 'mdat' but now we only stop parsing at the 'mdat' if we've already processed the 'moov'.
