gillespie.skip@gmail.com 0 Posted April 6, 2017 Share Posted April 6, 2017 (edited) Hi all, I've been an Emby server user for a while now. Within the last couple of weeks though I have a problem. I cannot watch live tv. When I select a channel from the guide, the video looks like it is running double time while the audio is normal. It will do that for a couple of seconds until it has to buffer more video. This is a recent problem. Never had an issue in the past. It does it regardless of whether I am streaming it to my android devices, to a web interface or to one of my Roku TV's through the Emby Channel. InfiniTV 6 eth with a cable card. Windows 8.1 Pro with Windows Media Center ServerWMC Now using Emby 3.2.10.6 beta Was using Emby 3.2.10.1 (I think) when this started. I have no idea what might have changed to cause this to happen. Any help would be greatly appreciated. Skip Gillespie P.S. I can watch anything from my media library and it plays perfectly without a hiccup.

krustyreturns 191 Posted April 6, 2017 Share Posted April 6, 2017 I had 10.0 installed and didn't see the problem, so I installed 10.7 beta and I still don't see it (tried a couple of channels). Do you know if your channels are h.264 streams? maybe that's the difference, because mine aren't. I imagine Luke is going to want emby logs.

Luke 37098 Posted April 6, 2017 Share Posted April 6, 2017 Yea I would certainly make sure to provide the information requested in how to report a media playback issue. thanks ! Link to comment Share on other sites More sharing options...
gillespie.skip@gmail.com 0 Posted April 7, 2017 Author Share Posted April 7, 2017 Sorry about the lack of logs. I'm a little new to the forum. Here is the server log and the ffmpeg transcode log. server-63627120000.txt ffmpeg-transcode-fb2a9d04-1d0b-4d30-9702-dd97d3dae5db.txt Link to comment Share on other sites More sharing options...
Luke 37098 Posted April 8, 2017 Share Posted April 8, 2017 Can you try installing VLC and plugging the serverwmc url from the transcoding log into that? @@krustyreturns will that work? Link to comment Share on other sites More sharing options...
krustyreturns 191 Posted April 8, 2017 Share Posted April 8, 2017 (edited) Yes, that works. In vlc you have to open it as a 'network stream'. Edited April 8, 2017 by krustyreturns Link to comment Share on other sites More sharing options...
gillespie.skip@gmail.com 0 Posted April 8, 2017 Author Share Posted April 8, 2017 (edited) I started a stream from my android device through Emby. It did the usual fast video with normal audio. I placed the serverwmc url from the resulting log immediately into VLC. It played perfectly with normal, synchronized audio and video. ffmpeg-transcode-75e9d310-8b0c-48fd-96a2-ddb870c5f7f7.txt Edited April 8, 2017 by gillespie.skip@gmail.com Link to comment Share on other sites More sharing options...

krustyreturns 191 Posted April 9, 2017 Share Posted April 9, 2017 Thanks. Never mind then, I thought it might be a problem related to a much older version of swmc. We'll need @@Luke and company to comment on the emby logs. Link to comment Share on other sites More sharing options...
Luke 37098 Posted April 9, 2017 Share Posted April 9, 2017 For the next release, we're going to update our vsync param that we pass into ffmpeg. If you'd like to try it in the beta server, the change should be available for testing within the next couple days. Thanks ! Link to comment Share on other sites More sharing options...
gillespie.skip@gmail.com 0 Posted April 10, 2017 Author Share Posted April 10, 2017 (edited) What can it hurt. Right now I'm paying for an Emby service that I can't use. I'll try anything at this point. Obviously something changed. Is there a way I can go back to an older version, in the meantime, and get my live tv back? As of right now, I can't watch any live tv on any of my Roku tv's. Edited April 10, 2017 by gillespie.skip@gmail.com Link to comment Share on other sites More sharing options...

gillespie.skip@gmail.com 0 Posted April 14, 2017 Author Share Posted April 14, 2017 Okay. Tried the beta version. Still had the same issue. So then, I completely uninstalled Emby Server. Used the "leave no trace" option. I reinstalled the latest stable version (v3.2.12.0). After setup, I tried to play a live tv channel from the web interface on the pc. It played perfect. So I tried to play it through my Android device. It still had the same problem: normal audio, fast video. So I went back to the web interface. When I tuned in a channel this time, it was now back to the same problem. So, I blew it completely away again, and this time installed the beta version (v3.2.12.5). After setup, right from the start, it still has the same problem. Any ideas? server-63627789357.txt ffmpeg-transcode-d63f0e9e-7f88-407e-8188-bdad1f9552ea.txt server-63627789159.txt Link to comment Share on other sites More sharing options...
Luke 37098 Posted April 15, 2017 Share Posted April 15, 2017 Ok, I cannot reproduce this with our built in live tv functions and I don't have a server wmc setup to test with, but I will continue testing this, thanks. Link to comment Share on other sites More sharing options...
epayson85 72 Posted April 16, 2017 Share Posted April 16, 2017 FYI I can confirm this is also happening on android if I don't have direct play enabled. Obviously I prefer direct play which works fine but just wanted to give it a shot to see if I could reproduce what gillespie is seeing on the Roku.

krustyreturns 191 Posted April 29, 2017 Share Posted April 29, 2017 @@Luke, yeah that would probably fix it too (and be better). If you are asking why does swmc have the ability to generate a 'fake' dts, it has to do with how a wtv packages h264 and problems that some versions of kodi had with these files. I can go into more detail if you want, but that basically it. Once we started generating dts in the ts file we generate for live streams, our kodi issues went away, so all was good, until Emby decided it didn't like it for some reason. So possibly this workaround could cause kodi issues depending on the version of kodi they are running. Link to comment Share on other sites More sharing options...
Luke 37098 Posted April 29, 2017 Share Posted April 29, 2017 I wonder if newer ffmpeg versions used by emby are the reason for the change. Link to comment Share on other sites More sharing options...
