Stuttering during direct-play

tachiomatachioma Posts: 6Members ✭✭

Samsung UE65JU7000 - Wired ethernet. Version 2.008
150MB virgin fibre

dual xeon e5520 @2.27Ghz with 4 cores
28GB ddr 3
gb NIC with gb internet connection
data is served locally off 14tb raid 5
Ubuntu server 16.04
Plex server Version 1.7.5.4035

So, i've been looking around for a couple of weeks and haven't found anything concrete. Initially, I thought i might be falling foul of the 2.008 stuttering issue, but the more I read about it, the more it appears not.

The below is a recent example. The picture will freeze for say 2/3 seconds then continue and will happen again in random places. I've tested with different files and the same file, placement is random. From limited testing appears to be only larger mkv's (12gb plus )

Bandwidth seems more than sufficient on either end. It's not during busy / high detail scenes (hair close up, large explosions etc)
Running a top when direct-play shows server is barely being touched cpu/mem wise. bmon shows outbound traffic never peaking above 9mb/s

Anyone have any ideas?

    Works fine when transcoding or direct stream too.

    Please try this: Unplug the TV from the mains for a few minutes.

    Hey Orca! Tried it, left it for 10 minutes. Tried watching again ... buffer at 5 minutes 27 seconds :(

    It looks like you may have a permissions issue:
    ERROR - [Notify] Failed to add watch for ... (13: Permission denied)

    If that happens too much the server might run out of connections.
    Please check if the user that is running the PMS service has enough access rights to the files.

    ok, so, just to test, i chmod'd my entire movie directory to 777 (which the majority was already to be fair) and changed plex to run as root. same issue at 3 minutes something... more logs?

    If it plays fine with lower bitrate movies, it might be to much for the TV to handle.
    If you have a fast server, you could try switching to Transcoding

    Check this as a guide

    Weird that no one has seen this before though right? I'm sure if i switch to transcoding it will work, just the loss of quality :(
