This would still depend on a constant frame rate though? I can't
guarantee that the source or encoder won't drop frames so it needs
to be robust against that.<br>
<br>
Besides, my encoder has options for VUI but the documentation states
that these parameters are ignored.<br>

Not exactly. The code assumes a frame rate of 25 fps *only if*
there is no timing information in the SPS NAL units.</div>

</div>
<div>If you want your video to be streamed at the correct frame
rate, you should make sure that the SPS NAL unit contains
“vui_parameters”, which in turn has the
“timing_info_present_flag” set, with the “time_scale” and
“num_units_in_tick” fields set. In other words, you’ll need to
reconfigure your encoder to give you this information (if it
doesn’t do so already).</div>
