No stream since move from homebridge V1.6.1 Docker to Homebridge V1.7.0 Synology

[Franco268]

Describe The Problem: I backuped my homebridge docker and I restored it on the Synology "app". Then I updated it to V1.7.0 Since I wasn't able to see pictures of my cameras on Home app. I tried to go back in V1.6.1 but without succes...same result.

But that is still woking well on the docker version.

(For info, I didn't start both together)

Is it an issue only on Synology version?

I don't know Synology at all, but is it possible there is some firewall or similar blocking network access? It may be easier to tell what's happening if you shared a log with debug active.

From my point of view my Syno firewall is completelty onpen in the local network.

That’s a very weird error, best guess is something is wrong with whatever version of ffmpeg you have?
