PLEX and SUBs (won't play properly)

[Ruttus]

Server Version#:1.18.4.2171-ac2afe5f8
Player Version#: Version 4.20.1 (all player has the issues)

My Anime’s won’t play properly when I add subs, is there a way to fix this?

without sub it plays great

but with it plays like above and can’t see nothing. moves extremely slow or don’t. even play at all.

Yes, this is known problem which has been going on a while. .

There are several threads about this.

Several workarounds including removing the intel driver shared object
“/volume1/@appstore/Plex Media Server/lib/dri/iHD_drv_video.so”
and restart PMS.

For example see

As confirmation, Revert to 1.18.0 (public) and retest ?

[Ruttus]

Thanks, I haven’t read all the comments yet, I would like to keep my current version and not upgrade, as since this last update the server works smoother and faster so I rather not downgrade to 1.18.0 public. the“/volume1/@appstore/Plex Media Server/lib/dri/iHD_drv_video.so” work around where can I find this on a Synology Nas?

On a QNAP you can turn off hardware acceleration and it works.

Intel video driver problem. Three options: Turn off hardware accelerated transcoding Fall back to version in Package Center Delete offending driver.

Yes, I keep the latest version too. You have to remove iHD_drv_video.so every time you upgrade. The issue is still in the process of being addressed.

You’ll need to ssh into your NAS to get command line access to remove the iHD_drv_video.so file above. For example see post 32 in the thread I linked to above.

ok I will try that soon but for now I Turn off hardware accelerated transcoding and works, but I feel turning that off will slow things down.

@Ruttus

but I feel turning that off will slow things down

Yes. You may see buffering when transcoding high bit-rate 1080p video. Transcoding 4K video in software will definitely fail.

Deleting the offending driver or falling back to an unaffected version of Plex is the preferred workaround. It forces Plex to use an older, different (but working) driver when hardware acceleration is enabled.

[Ruttus]

ok thanks I will do the delete of the driver. will check on how to do that. I don’t want to downgrade and I will need the hardware accelerated transcoding on.

It is a problem with an Intel driver and hardware accelerated transcoding. Plex is working with Intel on a fix. Quick workaround: turn off h/w acceleration (granted, may not be feasible due to CPU limitations). Less quick workaround: delete offending driver. See post below for additional details. Use PuTTY or similar to SSH to your DS. Also, you’ll need to use the sudo command to gain root privileges. Preface the mv or rm command with sudo or use sudo -i to become root. sudo -i cd "/va…

deleted and its working with accretion on thanks a lot for the help
