This is wrong. Some codecs may consume hundreds of frames before outputting
a single packet.

This is wrong too: the frame you just encoded does not necessarily come from
orig_pkt. You need to use the timestamp fields in the frame.
In the future, please provide minimal but complete programs. Your program is
not minimal, it contains a lot of code unnecessary to show the problem, and
nor is it complete.
