java.lang.IllegalStateException: Of all AUDIO sources, some have a AUDIO track, some don't.

I used the demo app to select and run one video with audio and one without audio, and I got the following error:

E/TranscodeEngine: Unexpected error while transcoding.
    java.lang.IllegalStateException: Of all AUDIO sources, some have a AUDIO track, some don't.

Facing almost similar issue with Audio. For some videos the video duration is changed (i.e. 9 secs video is converted to 15 or 18 seconds) and audio gets effected accordingly.

Any updates?

This issue seems related to #180. The library should technically add BlankAudioDataSource to every video that doesn't have it's own audio track before transcoding, however this doesn't seem to work at the moment.
