Every time I try to watch a movie or TV episode, playback goes for like 2 seconds then freezes for another few seconds then plays again. And it repeats the same process. It has only been happening for the last 2 weeks. I am eager to find out why as my internet is pretty fast as well as my computer specs. I am using Emby Server Version 3.0.5588.1. Running Chrome Version 42.0.2311.90.

Speed test shows I get 19.98 Mbps download and 1.48 Mbps upload. 

 

I have attached a log file from when it happened. Not sure if it will help or if anything else is required. I am new to this haha. Any and all help is welcome.

you're only getting 11 fps so it looks like your cpu just can't keep up

I updated my pc and restarted it for the first time in about three weeks so probably just been over run too long. It is working fine now. PC running i7-4770K @ 3.50GHz.

I seem to be having the same issue again, I have no idea how my CPU could be under pressure. Media loads fine on my android device. And this is running on the same computer so there is no internet involved. Is there like some sought of setting that I can change as it used to work fine.

 

Cheers

We'll have to look at an example

I've been experiencing the same issues as well in the last couple of weeks. It used to stream fast and smooth and now even when i turn the quality down to the point where it's almost unwatchable (144p), it still pauses/buffers. I'm running a AMD A8 quad-core 3.0GHz cpu w/ 16GB of ram and when I monitor the system, ffmpe.exe is maxing out all 4 cores.

 

Did something change in the transcoding configuration because I've been using MB/Emby for years and never had an issue before. In fact, I used to run it on a slower system (3-cores, lower cpu speed and half the ram) about a year ago and it still ran flawlessly.

 

Any help is greatly appreciated!

 

EDIT:

Sorry for hijacking the thread...I made a new post along with my log files here:

thanks in advance!

I am facing similar issues not just with Chrome but with Opera and Firefox. A few updates before I had no problems at all. Performance should not be an issue (Core i7 4 Cores, 16 MB RAM).. as I said I was experiencing no issues before. Something else I noticed is that ffmpeg runs (albeit consuming quite a few system resources) but it generally goes way ahead of the currently displayed video (one may notice the green back is behind the orange one in the dashboard), so my conclusion is that this is not a transcoding issue but actually how the temporary ts file is streamed to the client. I am aslo able to play the temporary  transcoded ts file in VLC without issues.

 

This is specially noticeable while trying to DLNA play to PowerDVD 15 as the video will contiously show "buffering" while playing any type of file but transcoding may be very well completed. (I tested this out with a 5 minute video where PowerDVD would show buffering but transcoding bar (the orange one is very well at 100% and the temporary ts file playable to the end in VLC)

 

A couple of snapshots...

 

This one shows the DNLA PowerDVD client. As you may notice transcoding is already completed (lower blue bar).

While PowerDVD shows a ´buffering´ message:

Again, this does not seem to be related to a performance issue.... CPU is not overloaded...

and transcoded temporary file is alive and well (and fully transcoded)...

With the last update I am noticing something unusual. There are many temporary .ts files being created. Is this normal?

After a few minutes from playing a tv show in the web player there are about 100 of these files.

 

Attaching sever log and transcode log files.

I'm in the same boat as you @Smaky -- after only a few seconds of playback I saw 152 transcode files get generated and it kept growing until I stopped it.  That does not seem normal.  Can @Luke or anyone else explain this?  :huh:

Those just look like hls segments.  Where are they being created?

i'm going to increase some buffer sizes on the server so we'll see if that helps. Note that Dlna does not use HLS so these are two completely separate things, even though the symptoms are similar.

They are the .ts files generating in my transcoding-temp directory.

Same here... they are generared under the transcoding-temp directory. An on your comment with DNLA... yes my previous post was related to playing a tv-show via the web player. When testing DLNA play to... I noticed there´s only one file being created.
