Video stuttering

[Nem 2]

I'm running Emby 3.4 in an unraid docker container, and whenever I play media the video stutters. I am direct streaming the media. See the video here:  https://www.dropbox.com/s/86w2hvrlrflbv14/emby_Large.mp4?dl=0

 

The linked video is a bit choppy just because I captured at a fairly low framerate, but you'll see there are some major stutters and visual glitches throughout the short clip

 

The media file itself is fine when I play it in VLC

 

I have also tried this with different media files, and on both my desktop and laptop (both Windows 10) and I get the same issues no matter what I try

 

Stats for nerds:

 

 

Server:

- i7 4790 @ 3.6GHz

- 8GB RAM

- Unraid 6.5.1

- No hardware acceleration in Emby > Transcoding

 

This started happening maybe half a month ago, but has been a consistent problem and makes emby unusable

 

Any thoughts on how to diagnose this?

After playing around with a few things it seems this only happens when I try to direct play 1080p videos. If I take the same 1080p video and transcode it to 720p it plays pretty smoothly

 

What could be causing this?

 

When I play the same 1080p video at full resolution across the network using VLC it plays OK, so it cant be my network speed. What is emby doing when direct playing full resolution video, that isnt happening when I play the file direct over the network?

Try lowering the in-app quality setting in the web app to force a full transcode, and then you should be fine.

 

You can't compare VLC to the web app because VLC can play lots of formats natively that web browsers cannot. If you want to use the web app then you at times you may have to accept some server involvement in order to convert the media.

 

You said this is on a windows 10 laptop. You may want to try Emby Theater, which embeds mpv:

This can direct play just about everything and is a better comparison to VLC.

What Im confused about is why this happens with one file and not another when both are mkv files and encoded using the same video and audio codecs? The only difference I can see is the video resolution. So if this is an issue about formats that web browsers can play, shouldn't they both work?

[Luke 42079]

Not necessarily, if it's just one file then it could be something in the video stream of that file that the browser doesn't like.
