Why MediaExtractor getTrackCount returns 0 in andr

问题:

I ran exactly the same code on:

  • Android 4.1.2
  • Android 4.2.2
  • Android 4.4.2.

It works well on 4.1.2 and 4.2.2, but NOT on 4.4.2.

The problem is MediaExtractor.getTrackCount returns 0 on 4.4.2 (while it returns the right number on other devices)

Any idea?

I am also facing the very same issue. Did you got the solution ?
