Let me understand your usecase correctly

It seems to be a demux-mux pipeline. Demuxer will simply return timestamps
present in PES. rtp packetizer can't do much. If you think there is no clock
skew, you mght want to disable skew calculator inside tsdemux element

And regarding timing information in H264 encoder, it is hardly present in
any H264 ES. f it is present, it will be present in SEI with payload_type=1.
VBV buffer removal info of SEI in association with HRD parameters of VUI
will give meaningful timestamp of every picture. But you mght not want to
assume this info is available all the time
