Unable to seek transcoded streams in Plex Media Player



Hello, I am a relatively new Plex user, and so far I am really liking the software.

I have run into an issue when using the Plex Media Player on Windows, and I want to know if I'm just doing something wrong, if this is a new issue, or if it's just a long-term problem with the software that I can't do anything about. The issue is that I am unable to seek when doing any kind of transcoding. If I am playing media without transcoding (Original quality) then it works fine. But when transcoding, all of the seek options (e.g. jump forward or backward, or using the location bar) don't work. This issue happens on two systems, one running Windows 7 and one running Windows 10, so I don't think it's a system issue.

The logs show this when I try to seek:
2017-10-03 07:17:09 [ DEBUG ] PlayerComponent.cpp @ 526 - cplayer: Run command: seek, flags=0, args=[3790.000000, absolute+exact, unused]
2017-10-03 07:17:09 [ ERROR ] PlayerComponent.cpp @ 532 - cplayer: Cannot seek in this file.
2017-10-03 07:17:09 [ ERROR ] PlayerComponent.cpp @ 532 - cplayer: You can forcibly enable it with '--force-seekable=yes'.

Other apps don't seem to have this problem (I have tried Roku and the Windows 10 store Plex app, and it worked fine). Is this just normal with the Plex Media Player?

Thanks for any guidance!


I’ve encoutered this too I think this has to do with the desktop client, I have multiple users having problems with this.
Using the Android client and the Chromecast option on the android phone there are no issues at all seeking the video file transcoded or not.


It may be this issue: github.com/plexinc/plex-media-player/issues/616
That’s talking about the Mac version, but if I understand correctly they come from the same source code.


To add on this I am on the latest Plex pass version though my fiends on the older version do have the same problem.


Same situation here, only on transcoded streams in PMP.


It looks like the folks over on github are looking to get a fix out soon. github.com/plexinc/plex-media-player/issues/616#issuecomment-335587862


Just an update: A Plex Media Player update was pushed to me yesterday, and the seeking issue fix was in the release notes, and I can confirm that it appears to be fixed!

I have since found that only the non-Plex Pass version of the PMP has been updated. The Plex Pass version hasn’t been updated since September 25, so it still has this issue. I’m not sure what the differences between the Plex Pass PMP vs non-Plex Pass PMP are, since it seems to me that most of the Plex Pass features are on the server side.
