H264 RTP depacketization failure due to unsupported MTAP16 and FU-B NALUs #273

There are reports of OBS 30.1.2 failing with ingress, sometimes after several hours of broadcasting. Ingress logs show the following errors coming from the Pion H264 depacketizer:

NALU Type is unhandled: 26 NALU Type is unhandled: 29

These correspond to NALU types MTAP16 and FU-B, which don't seem to be supported by Pion indeed.
