Unable to fast forward

Hello. I've googled and seen this topic for quite some time now but haven't seen a solution. I have some episodes of anime that I can FF just fine, and others that won't FF at all. Any time I try to FF it just resumes playing from where it was. Logs attached. Samsung 65" UN65RU8000FXZA running latest emby.

That generally means there is something not quite right in the mkv header.

Try this: open the file in MkvToolnix and copy all the streams to a new file. Add the new file to Emby and test it

Thanks for the response. I don't know how to use that program or what exactly you mean by fixing the mkv header, so if you could provide more info that would be great. I've already installed mkvtoolnix but never used it

SamES is asking you if you can remux the file as he suspects the header information of the container in your original file may be corrupt.  Remuxing just takes the original content video, audio, etc tracks and puts them into a new mkv container without changing the original contents inside the container.

1. Drag-n-drop tour original file into the Source files box
2. Click the Start multiplexing button

Should run fairly quick.  Then retest using the new destination file.

Got it. So I did this with handbrake and it worked. I’m currently redoing every episode. It’s also a problem unique only to samsung tv. Doesn’t happen on my pc, laptop, or mobile app.

The problem with Handbrake is that it reencodes your input.  I haven't used it in a while, but I don't believe it has an option to just remux like Mkvtoolnix does.

Edit: If it still doesn't work after a remux  (but works with your reencode) then it's probably not a header issue and SamES might need to relook at it again.

Some apps are more lenient with header problems.

Only issue I’m seeing with handbrake is the file size is coming out smaller but I’m not losing quality. I’m still getting an h264 mkv output. Only change I’m making for myself is personally idc about losing the english audio. I always watch anime in japanese with subs. So I’m removing the english and then hardcoding the subs. It’s working now on emby so I’m fine if it is in fact reencoding as it doesn’t seem to be having any real negative impact.

Sounds good.

BTW you can remove unused tracks with Mkvtoolnix also.  In the Tracks box just uncheck anything you don't.  Everything else is remuxed unchanged.
