Reviewed by Xabier Rodriguez-Calvar.

Since our pipelines now synchronize on the system clock the buffer PTS are huge and setting that as
negative pad offset introduced sync issues. If the video track started first and then an audio track
appeared it would be delayed and wouldn't start. Remove the pad offset and expect downstream to
perform synchronization.
