Comment (by FishB8):

 Yes, this happens with both. I actually started with librtmp, and then
 switched to internal to see if it made any difference. (Off-topic: which
 of those 2 is recommended? which gets more dev attention?)

 I have not tried it with other rtmp servers other than nginx. The
 timestamp reset happens when the rtmp server internally switches between
 source inputs. (In the example file, both sources were live) Here is a
 link to the blog post when the feature was introduced: http://nginx-
 rtmp.blogspot.com/2014/01/redirecting-streams-in-version-111.html

 I'm not very knowledgeable of what is and isn't allowed in the rtmp spec,
 so if the nginx implementation is a departure from the spec, let me know
 and I will submit a bug report with that project. I'll ask the developer
 what documentation he's basing the feature off of. There is always the
 chance that I am not utilizing the feature correctly.
