Fatal Playback error after upgrade to 10.10.3 on Synology

[TheDreadPirate]

Are you using host networking or bridge networking for the container?

Getting the same issue with 10.10.3 jellyfin/jellyfin in docker, anytime transcoding is enabled the playback fails fatally. Everything worked fine pre-update, QSV enabled transcoding included.

Are you using host networking or bridge networking for the container?

Not to my knowledge. Should I be?

At this point, should I just uninstall and try to install from scratch (I'd have to redo my libraries and everything)? Or do you think I'll come into the same problem using the latest version?

You can use either networking mode, but host networking reduces the number of factors to work through. And some people experiencing this problem were able to resolve it by switching the container to host networking.

Registered to answer here. Have the same issue. Updated today on my synology via docker. Can play on TV, PC etc.
Did someone solve this?
