Here is the ffmpeg command that emby uses:

I have tried also adding the discardcorruptts and fillwallclockdts options, but these don't seem to exist with jellyfin-ffmpeg
I have also tried adding a lot of error handling flags to ffmpeg, which results in this:

I think this shows the the HDHR is loosing the signal for so long that it closes the stream. So I think the only way to work around this in jellyfin would be to add some proper re-connection logic that know when video is lost and does a full reload.
