Video file size / time length reported on client truncated

I am using Serviio 1.5.2 (although have seen this ever since 1.5.0).
On some of my DLNA clients (e.g. Samsung TV) I see a truncated time length and file size for new video files. The files are copied over Ethernet to the Serviio server storage via Ethernet, and so take sometimes minutes to copy.
If I rename the file on the Serviio server (obviously after the copy has completed) then the problem is rectified (after I disconnect/reconnect via the DLNA client).
I assume this has something to do with the new inotify feature?

Probably. Can you post detailed log of adding that file? It should 'block' while the file is being copied, but it might be OS dependent.

A Force refresh should fix it too, right?

A force refresh does fix it.

I tried a different file this time, but same behaviour.
My server is Ubuntu 14.04.
I watched the log using "tail -f", while I added the new file. The file was nowhere near complete finishing to copy before the below happened.
The real file size is 1,503,410,669 bytes.

There is a file size check, file is deemed complete if the file size is not changed within roughly half a second. Possibly on your system this might happen?

Seems unlikely; the file operation runs at 30MBytes/sec and the server is a Core2Duo top whack 3.2GHz on Ubuntu 14.04LTS server. The drive is an external USB2 jobby.

'Googling this kind of thing, it looks like finding out when a file copy has completed in Java is a problem.
Would it be possible to add an option to allow changing the file size timeout period?
