arrmo 6 Posted February 18, 2015 Share Posted February 18, 2015 Hi, It seems that MediaBrowser forces transcode in the WP app, even if transcode should not be required. Is there a way to avoid this (DirectStream is much more responsive, and less CPU load on the server of course)? Thanks! Link to comment Share on other sites More sharing options...
arrmo 6 Posted February 28, 2015 Author Share Posted February 28, 2015 Hi, I have been trying to dig into this, I admit - confused as to why transcoding happens (but for me at least, it's a concern as it tends to load my server quite a bit). I have the application set to allow a high maximum bit rate, so it shouldn't transcode (on the server) ... but it does. Is there a way to see (in the logs) why transcoding is initiated? Thanks!

Luke 37112 Posted February 28, 2015 Share Posted February 28, 2015 Can you give some examples? please see http://mediabrowser.tv/community/index.php?/topic/790-how-to-report-a-problem/ Link to comment Share on other sites More sharing options...
arrmo 6 Posted March 1, 2015 Author Share Posted March 1, 2015 Hi, You bet, no issue at all! I was hoping to try to take care of it myself, just let folks know the answer - try to help out that way. No luck so far though ... . I'm running MB3 server Version 3.0.5518.28564, and the WP client is current (Version: 8.0.65.0). I have attached the server and transcoding logs (did a fresh restart of the server right before capturing this, to avoid sending you a 60 MB log file ... ). Don't worry about the messages in the transcoder log that say "Past duration 0.778130 too large". I'm using a version of ffmpeg that I built locally, as I'm also trying to test out nvenc encoding (not in this run, and it's not really part of the issue - I don't want transcoding to start at all!). The client is set for 480p (I have tried 720p also, no joy), and 4.5 Mbps ... this is higher than the source file, which is an mp4 file with Media Info as below (from MB3) -> so transcoding should not take place, correct?

arrmo 6 Posted May 5, 2015 Author Share Posted May 5, 2015 Hi, Any thoughts on this? I admit, it is a bit painful to have transcoding taking place when not needed ... . Thanks!!! Link to comment Share on other sites More sharing options...
Luke 37112 Posted May 5, 2015 Share Posted May 5, 2015 First update to the latest version of the server and the app. Link to comment Share on other sites More sharing options...
arrmo 6 Posted May 5, 2015 Author Share Posted May 5, 2015 Hi, I believe I am - but I could be wrong! Here is what I have, - Server: 3.0.5597.1 (it says it's current) - App: 8.0.66.1 Is this right? FYI, it's an MP4 file that is being transcoded. Thanks! Link to comment Share on other sites More sharing options...
ScottIsAFool 517 Posted May 6, 2015 Share Posted May 6, 2015 And it's still transcoding with 8.0.66.1? This version did have fixes in that should have sorted this so it only transcodes what it needs to transcode. Link to comment Share on other sites More sharing options...
arrmo 6 Posted May 6, 2015 Author Share Posted May 6, 2015 As far as I can tell - though I could be screwing something up, that's definitely not impossible ... . Source file is similar to above (offline transcoded by MCEBuddy, saving HDD space). I have set the WP app (for WiFi, which I'm testing over) to 720p, 7.5 Mbps ... so greater than the source ... thinking this means to not transcode. Make sense? Any things you want me to try, or logs that would help? More than happy to help out here if I can! Thanks for all the help. Link to comment Share on other sites More sharing options...
ScottIsAFool 517 Posted May 6, 2015 Share Posted May 6, 2015 Ok, let's try a different route, what's convincing you that it's transcoding when it doesn't need to? Link to comment Share on other sites More sharing options...
arrmo 6 Posted May 6, 2015 Author Share Posted May 6, 2015 Sounds good! I'm an engineer, appreciate the methodical approach .. . Here is what I did - it may be misleading me, feel free to comment / disagree! 1) If I take the file, put it on my web server ... and go to it from my WP (using IE) -> it streams fine, and of course no transcoding there. The point - WP can play the file back in native format. 2) I go to MB, select the file (and believe I have the settings such that it shouldn't transcode, though that may be wrong) ... logs on the server start to create transcode log files, and show transcoding. Also, jumping around the file is not very responsive (like 1) above), and new transcode log files start whenever I jump around. Also, CPU usage on the server jumps up, I believe indicating transcoding. Make sense? Am I out to lunch? Feel free to say so if I am ... Thanks!

arrmo 6 Posted May 6, 2015 Author Share Posted May 6, 2015 BTW, is it captured in the logs somewhere (either server or client side) why the decision to transcode is made? I'd be more than happy to go through the logs, find the info to get it to you (i.e. try to offload you). Thanks! Link to comment Share on other sites More sharing options...
arrmo 6 Posted May 7, 2015 Author Share Posted May 7, 2015 Hi, I have a feeling that the latest server update didn't take - as I did a reboot tonight (for other reasons) ... now transcoding doesn't seem to be happening (I don't think). Is there a way in the WP app to show the transcoding (or DirectPlay) on the screen (to check)? Thanks! Link to comment Share on other sites More sharing options...
arrmo 6 Posted May 7, 2015 Author Share Posted May 7, 2015 OK, now the skip forward and back buttons aren't working ... LOL. I keep breaking things ... ;-). Thanks for all the help! Link to comment Share on other sites More sharing options...
arrmo 6 Posted May 10, 2015 Author Share Posted May 10, 2015 Hi, FYI, just to follow up (on the skip forward / back buttons), - Web Interface: don't seem to exist, correct? - Windows App: Seems to FFWD / REW, not skip, is that expected? - Windows Phone App: turn white, don't do anything. Am I just messing up? I'm sure the buttons used to work, but it may be me. Thanks, ... Russell Link to comment Share on other sites More sharing options...
Luke 37112 Posted May 10, 2015 Share Posted May 10, 2015 For all three - yes, when direct streaming. When transcoding, the web app can skip/back perfectly in all browsers except internet explorer. Although Microsoft's new Edge browser works perfectly. For win 8, if you need skip buttons, then please request them in that section of the forum.

arrmo 6 Posted May 10, 2015 Author Share Posted May 10, 2015 Will do - thanks! Perhaps a dumb question, but how to get the skip buttons working in the Windows Phone app (direct streaming)? Just not sure where to ask. Thanks again. Link to comment Share on other sites More sharing options...
ScottIsAFool 517 Posted May 11, 2015 Share Posted May 11, 2015 It sounds like it's something I need to fix in the app. Link to comment Share on other sites More sharing options...
arrmo 6 Posted May 11, 2015 Author Share Posted May 11, 2015 NP, just wasn't sure if I was doing something stupid (entirely possible). Yell if I can do anything to help out! Thanks. Link to comment Share on other sites More sharing options...
arrmo 6 Posted May 16, 2015 Author Share Posted May 16, 2015 Hi, This may seem odd, but I think it's right ... it seems like the skip forward and back controls work if I am on cellular data, but not on Wi-Fi. Does that make any sense at all? Thanks! Link to comment Share on other sites More sharing options...
ScottIsAFool 517 Posted May 16, 2015 Share Posted May 16, 2015 Not in the slightest but it's something to work off, thanks. 1 Link to comment Share on other sites More sharing options...
arrmo 6 Posted May 17, 2015 Author Share Posted May 17, 2015 LOL - I understand completely. Just thought the observation may help to narrow the search (=less painful). Checked it again tonight - yep, seems consistent. Thanks! Link to comment Share on other sites More sharing options...
