[13:09:40] <jamrial> jkqxz: do we need 7cb9296db8 from libav?

[13:14:00] <jamrial> what do i do then? and shouldn't that be merged at some point?

movenc-test: Add tests for negative cts offsets

Signed-off-by: Martin Storsjö <martin@martin.st>
Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

movenc: Add an option for enabling negative CTS offsets

This reduces the need for an edit list; streams that start with
e.g. dts=-1, pts=0 can be encoded as dts=0, pts=0 (which is valid
in mov/mp4) by shifting the dts values of all packets forward.
This avoids the need for edit lists for such streams (while they
still are needed for audio streams with encoder delay).

This eases conformance with the DASH-IF interoperability guidelines.
