Description

Hi,

commit fbfcc8f1b71b51ff87f09e269d22328be5594f40 (avi: try to synchronize the points in time of the starts of streams after seeking) introduced severe audio/video sync issues in certain avi files.

Reverting that commit locally fixes the issue.

The problem can be easily reproduced with ffplay by seeking in an affected file.

One affected sample file:
http://files.1f0.de/samples/bb-sync-issue.avi

I simply cut the file off to limit its size without remuxing it, which does cause the duration to be shown wrong, however any seek will still break the sync.
