<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am new to Live555 and am trying to get the testOnDemandRTSPServer running correctly with an H265 encoded video. The video plays correctly when opened directly from VLC. However when I access it through the testOnDemandRTSPServer, it plays
at half the frame rate.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Looking into the code and referencing these two threads (<a href="http://lists.live555.com/pipermail/live-devel/2019-August/021257.html"><span style="color:#0563C1">http://lists.live555.com/pipermail/live-devel/2019-August/021257.html</span></a>
and <a href="http://lists.live555.com/pipermail/live-devel/2014-December/019007.html">
<span style="color:#0563C1">http://lists.live555.com/pipermail/live-devel/2014-December/019007.html</span></a>), this appears to be related to DeltaTfiDivisor having a default value of 2 in H264or5VideoStreamParser. The video does not contain any SEI packets,
so analyze_sei_payload is never called (which appears to be the only place that DeltaTfiDivisor changes its value).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I just recently started digging into the details of H264/H265 codecs so I could easily be missing something, but I would think that with the frame_field_info_present_flag=0, num_units_in_tick=1, and time_scale=60, the output frame rate
should be 60 fps not 30.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have attached the test video to help you recreate the issue (I am using the build from May 17, 2021).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Any help/clarification would be greatly appreciated.<o:p></o:p></p>
