Hi all,

I'm aware this issue has been posted many times. I've read just about all I can find on this topic and haven't been able to come to a resolution. I'm running the latest emby available on an RPI4 via Docker and OMV. I've tried using handbrake to convert my videos to smaller file sizes, convert them from 10bit to 8bit, lower the bit rate as low as 3mbps, and I've optimized them for streaming. However, remote users often report to me lag in my videos. I've included a log of a particular instance of a user streaming a less than 2G file that has been converted to MP4 format and optimized for web streaming. I have my RPI hardwired to my network, with 300/300 fios speeds. Even with a bitrate of 4mbps the stream is being processed in HLS and knocked down to 2mbps and 23fps. I'm completely lost on how to stop this lag, and seems to mainly happen with tv show files, not movies, although sometimes movies as well. Log has been attached, and I'm extremely not technical so please have patience if I don't understand what you're saying to me. Thank you.

Would appear to be an underpowered setup.  As it cannot process the media as fast as it wants to play.  But devs may have to comment more as transcoding is happening in software.

Just seems odd that an RPI4 with 8G of ram can’t handle this. And it almost never happens on movie files. Almost always tv shows. I even converted the files, made them smaller, and optimized them for streaming. And it’s almost always limited to a stick like a roku or fire stick. Idt anyone has ever reported lag directly from their tv app. And it’s also not with EVERY remote user, just a small handful. Too many variables here to be just my RPI being too weak.

Only thing I can think of is Roku are very stubborn and conservative on AUTO.  Set quality on client to a higher value to allow direct play assume you have the bandwidth.

Not sure what you mean about setting quality. My user has no streaming limit set in my emby. Do you mean tell them to make changes directly in the roku?

When media is playing via roku, click down on the remote and move right to the settings cog.

Here you can set the quality from Auto to varied other formats

I’ll recommend this to the user. If the file is 1080p should they try that or maybe choose a lower quality?

you will find several 1080 settings with varied bandwidth amounts. also 720 480 ect. All with varied bandwidth amounts.

I'm waiting for the user to try it. In the interim, I provided the logs you requested. Were you able to review them and spot any issues?

This looks correct. Does the connection have enough bandwidth to try increasing the quality setting in the app a little bit? Then that will decrease the chances that transcoding is needed.

It did not help. They are also experiencing lag using emby via Safari iOS.

Is this also with the same internet provider for both the IOS and ROKU? Or was the Safari IOS on mobile internet and Roku on Home Broadband?

There is also the Emby App for IOS.

Also, when the user in playing something, in the server dashboard under the current playing item, are there any messages there? ie, recovering from playback error or anything else

Same internet. Both home wifi. When the remote user is playing a video it says “lowering bitrate due to quality setting” if I recall correctly.

I’ve asked the remote user but they don’t use emby every night. They’ve got small children so it’s difficult to sit every night and watch tv. Still waiting to find out.

This did not work. The remote user is playing an episode of a show right now and it’s being transcoded down from 5mbps to 2mbps and receiving the message “reducing bitrate due to quality setting.” I’m not really sure what else to do here. Emby doesn’t really seem to work properly on Roku

I use Roku, and have done for years. I also have users who use Roku.

I see the message “reducing bitrate due to quality setting.” in dashboard sometimes for Roku remote users. But, the stream is stable to them and has no buffering issues.

Has the user got the Roku setup on a 720/1080/2160 Smart TV? I know that a certain older user of mine, only has a 720p sony TV, so I get this message when that user streams.

I dont know for sure if the message “reducing bitrate due to quality setting.” is relevant to the TV screen size, or just a coincidence.

If the user has a Smart TV and can access the Web Browser, you could ask them to try this route. Then you will see if the Web Browser produces the same result

 

Edit:-

I just ran a TV Show locally on Android Car Stereo, which transcodes media always. This also has the message “reducing bitrate due to quality setting.”

But, I get no lag, buffering or anything to interupt the stream.

Hi, can we please look at an example of when you tried this? Thanks.

Can you try asking them to lower their in-app quality setting a little further and see if that helps? Thanks.

They were watching two videos at once on two separate rokus earlier today. One was direct playing, and one was transcoding. At this point I can’t even explain. It just seems as if roku doesn’t have the best compatibility.
