Dolby Vision Media Improper Seeking

Video Playback
1

Media with Dolby Vision does not always jump properly when using the +/- 10 seconds actions on iOS or tvOS. Instead of jumping forward 10 seconds, I sometimes see it go right back to the original spot, or jump randomly between 0-10 seconds. This is a frequent occurrence for me on both iOS and tvOS. I tested while using HEVC at 1080p and 4K, and I believe only files with Dolby Vision are affected. Attached is an example of what I see.

Infuse 8.4.2

iOS 26.5 Beta

Jellyfin 10.11.8

I noticed this also. I would skip and it would look like it was going to skip 10 seconds, but falls back to the same spot. Also sometimes hitting skip once, or hitting it too quickly, changes it to a fast forward. This normally only happens at the beginning of the video.

I am using an older first gen Apple 4K if that helps.

I have the same problem. There is a post related to this problem already. It is a known issue and have been reported long time ago but it is still not fixed

Would you be able to upload a sample file we can review here?

5

Could you guys upload a sample file ? I got a very slow upload rate in my area

6

Uploaded one, let me know if you need more. I can reproduce it easily on a bunch of files.

Thank you very much!!

I’m using Emby and I’ve encountered the same issue. When I drag the progress bar to a specific time, Infuse always jumps to a few seconds after that time, which makes the auto-skip intro experience really bad. For example, if the intro is set to skip at 8s, Infuse will jump to 5s.

Can u upload a sample file by using james link above

10

I’m using someone else’s Emby and can’t upload files. I think this obvious bug can be reproduced just by finding a DV file. I asked other users, and they all reported experiencing the same issue.

11

Ok that’s fine. Could you try to ask the emby owner to upload a sample file. So they James can look at the issue

12

@james will u look at this issue soon ?

13

We will try and look into this behavior, but if anyone is able to send in a sample file that exhibits the issue it may help in tracking down the issue.

Dolby video seek has a 3-second or 4s delay in every Dolby video file.

seek issue,pull progress bar go ahead will recover original location
code ZN714

I have similar problem for some of my video

When I press fast forward it returns to the original position.

17

I’ve been seeing this issue intermittently but I never realised it was DV issue. Going to have to run some tests on my content and see.

18

no, it is not only dv, sdr have same issue

19

@s29 could u please upload more sample file to James? Please

20

I can not, because this file from other people build emby and this issue is not 100% happen, my only know infuse have serious seek issue, this requires @James to make up his mind to solve it, not tag research forever
