Details 
It currently only provides an API to seek , with no distinction of track.

This is similar to bug 1274445 which was for webm and had the same problem.

Fast seek in the old OggReader is broken: the audio track isn't seeked to the video track in order to preserve A/V sync and we end up always performing an accurate seek which explain why this test succeeded before.
The page index is only made of two entries, and so the first video frame returned after a seek, if within the first index will always have a time of 0.
