1090000 - Duration error introduced by seeking

Status: NEW

The test case tests if the duration remain the same before and after seeking. The duration is consistent on Chrome. However, it shows 0.300104 and 0.300121 respectively on FireFox.

This is because we have round-down error in MediaDecoderStateMachine::DropAudioUpToSeekTarget() when converting micro seconds to frames.

We should tolerant round-down error at http://hg.mozilla.org/mozilla-central/file/20408ad61ce5/dom/media/MediaDecoderStateMachine.cpp#l2503 so there is no slop in end time/duration.
