silvers4640 0 Posted February 9, 2016 Share Posted February 9, 2016 So ill start of saying im new to Emby and trying to migrate from Plex. The big thing that is making want to switch is the native support for live tv. Problem is everything seems to work fine except when i go to start a live channel. When i start the channel it streams for a few seconds then hangs. It does this local and remote. What i have noticed is ffmpeg shows cpu usage for about 3-5 sec then just stops. The memory usage remains but cpu usage stops. If i try to start another stream it opens another ffmpeg and does the same thing. It also ties up 1 of the tuners on the hdhr prime. I dont have any problems streaming directly from hdhr or using plex hdhr channel. This only happens with Emby. If someone more advanced can help out, i would really appreciate it. At this point willing to try anything. Few things i have tried is SD, HD, lowering stream quality, local, remote. So far nothing makes a difference. Thank you in advance for any help i get.

legallink 187 Posted February 9, 2016 Share Posted February 9, 2016 I have had previously similar expereinces. I don't know if you are running this under windows and have wmc, but if so, I would suggest installing server wmc and tying it into windows wmc. That has smoothed out my problems.

mjktg99 34 Posted February 9, 2016 Share Posted February 9, 2016 (edited) I have had previously similar expereinces. I don't know if you are running this under windows and have wmc, but if so, I would suggest installing server wmc and tying it into windows wmc. That has smoothed out my problems. That would negate the appeal of 'native support' of live tv. First and foremost, provide some logs. Shut down emby server, clear the logs. Start emby server and run a test. Then attach the server log and transcode log. Log path: %appdata%\Emby-Server\logs Edited February 9, 2016 by mjktg99 Link to comment Share on other sites More sharing options...
silvers4640 0 Posted February 10, 2016 Author Share Posted February 10, 2016 So after resetting it, the issue only seems to happen with any HD channel. SD started working fine after resetting the server. Not sure what logs you want so im uploading both. server-63590631807.txt transcode-4645630b-494c-403c-bd46-2e895f05289b.txt Link to comment Share on other sites More sharing options...

Luke 37008 Posted February 11, 2016 Share Posted February 11, 2016 Ok, what's happening here is, we don't know the media info ahead of time so we're doing a full transcode, and that's too much for your server (notice the low fps). Since the hdhr channel was written by SiliconDust, I think they have a way of querying the media info to indicate h264 and just stream copy the video. We used to prove the live tv feed dynamically, it's something that's been added and taken out several times due to side effects that it's created. This week I'll take another look at adding it back. If we have the media info that tells us the source feed is h264, then delivering it to the client application will be much more efficient since we won't have to re-encode it.

DiscoLives4ever 0 Posted February 11, 2016 Share Posted February 11, 2016 I'm having the same issue, however most channels that are MPEG2 will work without issue. Occasionally those MPEG2 channels also have the same issue, but I can't replicate why consistently. Regardless, if I monitor the ffmpeg process in task manager it will use CPU resources for a few seconds before dropping to 0% there, while still using 275 MB of memory and 100 kbps or so of network. If I end the ffmpeg process, it stops playback of the video however the reverse is not true (the ffmpeg process hangs even when I stop playback).

silvers4640 0 Posted February 12, 2016 Author Share Posted February 12, 2016 Ty for the reply. If you want me to do any testing for it i can. Like i said as soon as i get native full functioning tv support i think i will b ready to jump over fully to Emby. Also i did notice similar things to the post above. So just let me know if you want me to do some testing. Thanks again for the reply. Link to comment Share on other sites More sharing options...
Cobra 6 Posted February 26, 2016 Share Posted February 26, 2016 I am using HD Home Run prime (cable card) on Comcast and have not seen any type of problem with live TV. It buffers for 10 seconds or so and off it goes on IOS, nvidia shield tv or browser with excellent HD Quality. Emby is running on Windows 10, i7 5960X (16 logical cpu cores) but during playback of live TV the CPU use is only a steady 11%. The only time I am seeing excessive cpu use on server is if I am playing h.265 content and it is transcoding on the fly. Hopefully down the road direct play of that will be possible.

Has your area received the "Enhanced HD" rollout yet? They are converting channels from MPEG2 to MP4 and that seems to be where the issue lies.

Cobra 6 Posted February 26, 2016 Share Posted February 26, 2016 I am not sure......sorry I did not realize that was the root cause here. I am probably in the non-enhanced area. I do not see an easy way to check that without having a cable box. Link to comment Share on other sites More sharing options...

Aspect ratio issues can be down to your IPTV provider. Who do you use? I actually find very good HD content from m3u played om Fire TV and Android TV boxes predominantly.
