Crestj 67 Posted January 15, 2014 Share Posted January 15, 2014 (edited) Not sure how streaming is dealt with but it can be quite slow and buffer a lot. My server is an HP Proliant Microserver N36L. As it's cpu is not built for decoding / encoding, would a faster cpu be better for this or is it more down to wifi speeds etc? My wifi is 5ghz and the android devices are nexus 7's and Samsung galaxy tab 3 's.

Tikuf 663 Posted January 15, 2014 Share Posted January 15, 2014 Transcoding is pure cpu grunt work. We have some changes in the wings that may make it better for lower end cpu's but I don't think they will be fully finished by the next server build. Have a look at one of your ffmpeg logs that playback buffered in. Look for fps= if it is lower than the source framerate then it is down to cpu if it is higher then there is a bottle neck somewhere else. Link to comment Share on other sites More sharing options...
Crestj 67 Posted January 15, 2014 Author Share Posted January 15, 2014 (edited) Thanks, I'll take a look. Where are the logs Btw? I highly suspect my cpu is not up to this but upgrading means a new server :-( Sent from my Nexus 5 using Tapatalk Edited January 15, 2014 by Crestj Link to comment Share on other sites More sharing options...

Crestj 67 Posted January 15, 2014 Author Share Posted January 15, 2014 Ah right, the details are within the server log files? Sent from my Nexus 5 using Tapatalk Link to comment Share on other sites More sharing options...
Latchmor 584 Posted January 15, 2014 Share Posted January 15, 2014 (edited) Hi, they are in the same folder but the server and ffmpeg log files are separate. You'll easily spot them though as they have ffmpeg in the name! Cheers Edited January 15, 2014 by Latchmor Link to comment Share on other sites More sharing options...
Crestj 67 Posted January 15, 2014 Author Share Posted January 15, 2014 (edited) Lol oh yes! Incidentally I've just watched my cpu go straight to 98% when ffmpeg .exe starts and stays there with nothing appearing on my tablet. It would seem your average low watt / low power server cpu is the opposite that's needed for transcoding. I presume ffmpeg don't have a gpu capable version? I could put one of those in a server.

Crestj 67 Posted January 15, 2014 Author Share Posted January 15, 2014 Do people run mb Server on more powerful desktops for Android streaming then? Can you run 2 mb servers pointing to 1 library, one for transcoding and one for your htpc? Sent from my Nexus 5 using Tapatalk Link to comment Share on other sites More sharing options...
Crestj 67 Posted January 15, 2014 Author Share Posted January 15, 2014 Ok, looks like I need to investigate newer Server hardware then. :-( Sent from my Nexus 5 using Tapatalk Link to comment Share on other sites More sharing options...
Redshirt 1487 Posted January 15, 2014 Share Posted January 15, 2014 The CPU usage isn't the only marker as to whether transcoding is over taxing your hardware. Transcoding uses as much cpu as is available. It's still in the 90%+ range with my core i7. The real question is what are the fps= values in your ffmpeg logs. That defines whether or not your server can keep up. Link to comment Share on other sites More sharing options...
Crestj 67 Posted January 15, 2014 Author Share Posted January 15, 2014 Here's the log: https://dl.dropboxusercontent.com/u/11699277/ffmpeg-d7c82038-3e3b-400a-94f6-ff8467a074f1.txt Looks like it gets about 11 FPS but the movie plays for about 3 minutes and then pauses (rebuffering I guess) then starts again. Does that suggest the server CPU is not up to the task? (poor thing is only an old AMD Turion II 1.3Ghz !!!) Link to comment Share on other sites More sharing options...
Redshirt 1487 Posted January 15, 2014 Share Posted January 15, 2014 yeah it's transcoding at well below the videos framerate. The server can't generate the data fast enough. Link to comment Share on other sites More sharing options...
Crestj 67 Posted January 15, 2014 Author Share Posted January 15, 2014 Hmm do all you guys have the same issues or do most people use their desktops and leave them on 24/7? Sent from my Nexus 5 using Tapatalk Link to comment Share on other sites More sharing options...
Redshirt 1487 Posted January 15, 2014 Share Posted January 15, 2014 I have two servers running, one on my desktop which I dev on. The other is my real server which is a Core2Duo e6600 and it is able to transcode pretty much anything I throw at it. Depending on the source media it can even transcode more than one video at a time. That server runs 24/7. Link to comment Share on other sites More sharing options...
Latchmor 584 Posted January 15, 2014 Share Posted January 15, 2014 (edited) Hi, I have an HTPC which is on all the time and it runs the MBS. Most of my Media is on a NAS that I turn on/off as required. HTPC specs below, it was built 1.5 years ago and like Red above it transcodes anything I've tried.

markshu 7 Posted January 16, 2014 Share Posted January 16, 2014 (edited) I'm running MBS on a headless file server which has a soon-to-be-updated AMD Phenom II 960T. My main HTPC is a recent build with an i7-3770S (it has all the tuner cards), my secondary HTPC uses an i3-3225. All of these are separate from my main desktop system (which is also in need of a serious upgrade <g>). Both my file server (PII x4 960T) and my main desktop (PII x4 965) are capable of handling transcoding on the fly, but neither of them come close to the IvyBridge chips in performance. I'm rather fond of the i7-3770S' specs for low-end servers and HTPC systems - the TDP is only 65W and if you're smart you can make a system that is virtually silent even under load. Main HTPC: Silverstone Media Center case: ML03B Seasonic 80+Gold 360W PSU: SSR-360GP Gigabyte Z77 motherboard: GA-Z77MX-DH3 Intel IvyBridge CPU: i7-3770S @ 3.1GHz Kingston HyperX Blu 16GB (2x 8GB) 1600MHz DDR3 RAM: KHX1600C10D3B1K2/16G Samsung 840 Series 120GB Sata3 SSD: MZ-7TD120BW Western Digital RED 3TB Sata3 NAS HD: WD30EFRX Pioneer 15x Internal BD/DVD/CD burner: BDR-208DBK (4x) Avermedia PCIe Dual ATSC TV Tuner: A188 HD Duet (4x) Noctua 80mm PWM Case Fan: NF-R8-PWM With the four Noctua fans providing positive air pressure into the case and using the stock Intel cooler, all of the fans run at their loweset speed the vast majority of the time. You literally cannot hear the system from further than a foot away unless the optical drive is in use.

Luke 36893 Posted January 12, 2016 Share Posted January 12, 2016 fps means frames per second. In other words, how many frames per second it's able to encode. You need 24 fps for smooth playable video so that performance is quite good. Link to comment Share on other sites More sharing options...
