------ Start of attached email. Subject: Zoom Can't Render H.264 from Freeswitch 1.10 ------
Having trouble with transitioning from Freeswitch 1.6 to 1.10. When attempting to connect to a Zoom client the video from Freeswitch 1.10 fails to render in Zoom. Using Freeswitch 1.6 works as expected. The video from the Zoom client works fine on both cases. After much analysis of packet captures, the H.264 RTP sent to Zoom looks fine. It can be extracted from a packet capture and played using VLC. The RTP is being sent to the correct address / port, the payload type is correct as per SDP negotiation, same for packetization-mode. The stream sent to Zoom contains IDR frames preceded by SPS / PPS / SEI and is consistent with the stream from Freeswitch 1.6. Zoom sends frequent FIR and PLI requests as though it is not receiving any video / key frames. The capture shows no sequence number gaps, no jitter, no clock drift, etc.

Has anyone experienced this? Any suggestions on what could possibly cause this?

Thanks,
Bob
