hector 1 Posted January 13, 2014 Posted January 13, 2014 I am experiencing frequent pauses when watching the video using the web client. I have turned the quality all the way down to 240p and tested running it on the HTPC that has the server running and still have the same problem. Is it a case of my machine possibly not having enough power for transcoding and streaming? I have an Athlon II X2 265 with 8GB of RAM and an Nvidia 660 GPU.
Luke 42077 Posted January 13, 2014 Posted January 13, 2014 it's possible, although the next server release may help, so stay tuned.
Tikuf 663 Posted January 13, 2014 Posted January 13, 2014 As Luke said hopefully next server will help. But to confirm open up the relevant ffmpeg log and look for fps if it is less than the source framerate then the cpu isn't powerful enough (with current server)
bloodtaker 71 Posted January 13, 2014 Posted January 13, 2014 the Athlon II X2 265 is bottle-necking your Nvidia 660 GPU it just doesnt have enough horse power to use the 660 fully if you are streaming on another computer i would say the athlon would have issues it was never really a strong cpu to begin with when it comes to multiple threads single thread it was pretty strong though if mb server is setup for multi threading that may be your issue
Tikuf 663 Posted January 13, 2014 Posted January 13, 2014 Gpu is not relevant here it is just cpu and as bloodtaker said Athlon II X2 265 is not strong. There are changes coming that may improve it but for now just confirm it is cpu related by checking the ffmpeg logs.
bloodtaker 71 Posted January 13, 2014 Posted January 13, 2014 oops forgot to mention that tikuf what I meant to say was that the Athlon II X2 265 with the Nvidia 660 GPU was bottle-necking if you were trying to game on it and such, if it is setup as a htpc only you shouldn't have an issue. one other issue that might cause this would be a low quality router i had that issue as i had a old Linksys network everywhere router with wireless A. Now i am running a Linksys AC1900 and everything is smooth as silk could have also been that that router was old as dirt to lol
hector 1 Posted January 14, 2014 Author Posted January 14, 2014 I have a netgear WNDR3700 so I think that is not the issue. Also I tested on the computer running the server software. I will wait for the next release. Thanks.

Kelmino 17 Posted January 16, 2014 Posted January 16, 2014 I'm having this same issue for the past two days, I've been using exclusively the web browser since my laptop is a mac, before two days ago I had zero issues streaming any thing from 1080p down to 720p so it's weird. I just recently upgraded my processor to an AMD Phenom II x6 1040t processor and a SSD hard drive for my main OS & Application drive a few weeks ago when I upgraded to MB3. One thing I've noticed is ffmpeg.exe runs at about 40% when I'm streaming and my fan seems to be running loud on my main HTPC. I did order a new case fan since mine died a while back hoping that will help, that should be here tomorrow if all goes well and I'll see if that helps. Also on a side note I just opened up firefox on my laptop and the video seemed to play without an issue longer then it has in Chrome and the ffmpeg.exe did not jump up.I am using Chrome version 2.0.1700.77 Worked fine in Firefox version 26 Now I'm curious if my auto-updated version of chrome broke something on my end. Anyone else experiencing this same issue in the newest version of Chrome?
Kelmino 17 Posted January 16, 2014 Posted January 16, 2014 No. I'm using the version that was released on December 30th Version 3.0.5115.35703 Should I move to dev versions? The warning on the dev versions scared me away.
Kelmino 17 Posted January 16, 2014 Posted January 16, 2014 Also. I've been using that version of mediabrowser since about Jan 2nd or so and the issue just started within the last couple of days. Not sure without looking if any other automatic updates happened on the server. But I do know my chrome updated around the same time the issue happened. It looks. Like that version of Chrome was released about two days ago.
Kelmino 17 Posted January 18, 2014 Posted January 18, 2014 Just a quick update. Over the last couple of days I've been using only Firefox as a browser for Media Browser and I've had zero issues with anything freezing. I have tried Chrome here and there just to see and it did still freeze in the 15-30 second range each time.Now today I reset my SMC and my PRAM on my laptop (As mentioned earlier I have a Mac laptop) and everything seems to work in Chrome again, so whatever was causing my issue seemed to go away now so that was weird. Now one little quirk I did notice while running Firefox was that the screen always went to sleep (Have it set low) when my video was playing full screen, it never happened in Chrome, and I'm not using Firefox any longer so it's not an issue for me personally, but it's something I thought I should let you guys know about anyway. I did also test it again today after resetting my SMC and PRAM and it did still happen after that.
hector 1 Posted January 23, 2014 Author Posted January 23, 2014 (edited) This is still happening with ltest server version. It was serving 720p @1.5mbps to client running on same machine as server. During the pauses, the ffmpeg process spikes to 90% cpu. When video resumes it settles down to 66%. 1080p is unusable. This is on firefox. ffmpeg log during the stuftering/pauses: http://pastebin.com/WfvHvqiv Edited January 23, 2014 by hector
hector 1 Posted January 23, 2014 Author Posted January 23, 2014 So based upon the fps is a cpu upgrade then in order? Looks like source fps is 59.99 and transcoding hits a high of 40
jcain 7 Posted January 24, 2014 Posted January 24, 2014 my server has dual gig NICs teamed going to a managed switch (teamable) so it surely isn't a bandwidth or CPU e in some cases
Tikuf 663 Posted January 24, 2014 Posted January 24, 2014 The logs you posted indicate that it is cpu Conversion speed is 27 frames per second source is 29 frames per second. The webm lib is not properly multithreaded so we can actually only use 2 threads to your cpu if we limit the frame rate of the output webm to 23.976 it should solve the issue (for you).
jcain 7 Posted January 24, 2014 Posted January 24, 2014 (edited) I'm having the same issues a the OP. ffmpeg log at https://www.dropbox.com/s/lp91i8yuxh443pm/tv.txt ain't no way my 12 core (2.4ghz each) can't transcode a simple tv feed. i barely blinks when transcoding 30gig bluray for playback outside of the LAN, Edited January 23, 2014 by jcain
Luke 42077 Posted January 24, 2014 Posted January 24, 2014 Yes but @@Tikuf should we encode to a lower frame rate when the source is that high?
jcain 7 Posted January 24, 2014 Posted January 24, 2014 Seems as if my tv recordings playback is at the same disadvantage. it too pauses exactly like live tv does. neither do this on the extenders off the same wmc server. sounds like an ffmpeg thing or a web implementation
jcain 7 Posted January 24, 2014 Posted January 24, 2014 Well THAT isn't very server friendly then. 2 threads is still dual 2.4ghz. Doesn't make much sense.
jcain 7 Posted January 24, 2014 Posted January 24, 2014 heres the ffmpeg log to recorded tv playback that has identical problems as live tv playback https://www.dropbox.com/s/8fzpr3q5qp9268r/tv1.txt
Tikuf 663 Posted January 24, 2014 Posted January 24, 2014 Yes but @@Tikuf should we encode to a lower frame rate when the source is that high? Yes I think that will solve some issues.
