Some MKV content streamed on Plex for Xbox One is stuttering. I can't fast-forward or rewind, then the file starts over after a 10-20 sec lag. Also, some content starts somewhere in the middle of the MKV file. Some MKV content also just stops in the middle somewhere.
I run latest server (0.9.10.3.665) and latest Xbox One app.
Re-install app doesn't work. Reboot server and reboot PC doesn't work.
Streaming to Chromecast from Android app works better even though I can't fast forward/rewind. No stutter.
Sources that doesn't work well:
Resolution1280x720 (16:9)
Framerate23.976 frames/s
Ref. Frames9
AudioEnglish AC-3 5.1 @ 640kbps
Bitrate7789 kbps
Even though same technical info on another MKV file worked 100 % earlier.
My settings:
Size of IPC buffer (in bytes) when streaming transcodes: 4194304
What are the specs of your server? Are you trying to watch something with subtitles?
Since mkv isn't supported for 3rd party apps yet, it has to be remuxed to a compatible format. This is not very cpu intensive, but if you are adding subtitles to the mix they have to be burned into the video on the fly so that takes a bit more.

Running a Core 2 Duo @ 3 Ggz, 4 GB RAM.
Actually subtitles are already built-in in these videos that I've tried. Maybe that's a problem?
Otherwise I thought MKVs are transcended and that might be the issue?
Not really sure which one you have since you didn't include the model number but check here for benchmarks: https://www.cpubenchmark.net/
Give you have a core 2 it might be the case, I doubt that the remuxing to a different container is what is doing it since it is not very cpu intensive, but if you have subtitles enabled try turning them off. Another issue could be if you have dts audio which needs to be reencoded, but this isn't terribly intense either.
Well, from the logs you can tell that your processor is struggling. As I said in post #7, and you posted above, dts has to be transcoded to ac3. I'm guessing your processor is not up to the task. See below for log snip:

Notice the place where is says * speed => 0.5, this means you are transcoding at less than realtime (realtime is anything >= 1). Do you have mkv files that don't have dts that you can test with? Look at the link in my post #7 and check out the bench mark for your processor, you never stated the model number so I wasn't able to look for it.
Hmm, well, your process scores better than mine. You *should* be ok with a score above 2000 (my proc actually is about 1500). I only have 1 or 2 movies that are dts however, I'll give one a shot tonight and see what happens. I didn't see anything really off in the logs, but have to admit to being a novice when it comes to what to look for in them. Hopefully someone else will chime in as well.
Well I played a video with dts (only one I have) and it played fine. It was an mkv with h264 video and 5.1 dts audio. The xbox is hardwired to a 100mb switch. I know it's likely not much help, just a heads up. Maybe you could post the Media Info xml here to see more info on it. My file isn't very high bitrate either, about 4.3gb total for a 1:46 movie.
It is related to the DTS, but it is inconsistent, although most of the films I have with DTS will stutter, like as frame rate issue. I even have several films with DTS and Dolby soundtracks, and switching to the Dolby completely resolves the issue. Hopefully it'll be fixed soon =)
