The issue can be solved by increasing the number of sniffed packets here, but I don't think we want to end up with an ever increasing number here. I'll use this issue to track customization of the TsDurationReader behavior.

Note: This is also part of what #5097 is tracking, so it might make sense to duplicate to that issue and add any extra ideas that you have to that one?

Ok, let's mark this as a duplicate then.
