I'm having difficulty with my TCL RokuTV playback OF SOME CHANNELS of live TV using Emby BETA: the video seems to be transcoding slowly and lags behind the audio (which has no problems) a couple seconds.  My normal set-top boxes (Rokus 2, 3, Stick, and Ultra) have no such problem on the same channels.

 

Looks like it's transcoding @66fps 7.9 Mbps using m3u8 h264 video and ac3 audio.

 

Emby Server 3.5.3.0

Emby for RokuTV version 3.0.124

 

Logs attached & sent a log from the Roku channel for RokuTV.

 

IMPORTANT NOTE:  This problem is not showing in the normal Emby release channel for Roku TV, which I have as 3.0.111!

 

 

EDIT:  It appears to only happen on some channels, not others.  I am attaching a second set of logs (and just sent another log from Roku @ 11:29am PST) showing a channel that is transcoding @33fps and is running smoothly.  But the normal release channel (3.0.111) has no problem with the 60+ fps.

 

Figured I should report it.

Well this is also two different channels, so that makes this comparison apples to oranges. One channel is 30fps and the other is 60fps.

@Luke OK let’s just focus on the problem channel, which is indicative of most of the Xfinity channels I get. Can you identify any reason why the video is experiencing playback issues?

Well it's 60 fps but it doesn't look like your system can transcode it quickly enough at that high of a framerate.

 

@speechles this needs to be dropped to 30 fps

Hey @Luke and @speechles any luck on this?  I'm sure it's low on the list of priorities, but I really would like to have at least one channel (if it has to be done individually) set up in this manner - NBC Sports Net Bay Area, so I can watch the Golden State Warriors games.

 

Again keep in mind this is ONLY occurring on the RokuTV, not on the normal Roku set-top boxes.  But there should be no issue with dropping the fps to 30 for Roku in general if that is what's needed.

 

I am running

 

Emby Server 3.5.3 (let me know if I need to switch back to the beta series to help validate)

EmbyBeta RokuChannel 3.0.131

Server = Matrix3

 

Recent logs attached for this channel - NBCSBAH (720 on Xfinity Digital Bay Area)

 

Thanks folks & Happy New Year!

TranscodeReasons=ContainerBitrateExceedsLimit

 

Are you using a remote server or one local? If local can you set the Max bitrate in the app settings (press * on Home of the app). Choose 80 Mbps do not choose Auto. Now play your item and see if you experience the issue. The Auto may be detecting too low of an automatic detected bitrate to use in your case. You can't use the Video Player OSD to set manual bitrates fully as it adjusts to the resolution of the item playing or lower. It does not allow full control as the main settings menu does. Setting it manually can help it "get its head on straight" so to speak. Let us know what happens. Thanks and happy new year! :)

 

NOTE: The Roku cannot directly play the .ts container, but changing bitrate will allow it to copy the streams inside the container and hopefully retain sync.

Alas there is no change after trying this (on a local server).

No, don't do that for all Rokus as that will kill the temporal resolution.

 

I didn't look at the logs (sorry) but is this a 720 or 1080 station?

Yeah wouldn't do that. It would be sort of the same as the HEVC at 60fps setting and show for the user if it detects they are using a RokuTV. In that same way we could allow another option for those users who might experience issues to trim the 60fps to 30fps with a setting. Everyone without a RokuTV would never know those settings even existed as they would never see them.

That sounds AWESOME!!  Let me know when I can test it out!

We're just spit balling ideas here.  No developer has commented so I wouldn't get my hopes up for a "fix" just yet.

It's very possible this could get fixed/worked around in code and have no need for a setting.

 

Wait and see what the devs say and then you can always make a "feature request" for this option if needed.
