Playback on all Devices Result in horizontal distorted video - audio, subtitles, are fine

I’m running the latest Version of PMS - 1.18.2.2041 on my Synology DS 918+. Until recently (last 3-4 months) I haven’t had many issues with video playback.

However, I noticed an issue when renaming files before playing them, or moving them to the correct folders (sometimes the file is in a folder within the nesting folder, so I will remove the non-essential folder - too confusing?) that the playback is absolute garbage. This has become a more common issue for me - the video is distorted and has repeating vertical lines that move, showing that PMS is trying to play said file. When I play the file using VLC there are no issues. Typically to solve I delete the file from my Plex and re-add that file, however, in the last week I will have to download a new file regardless of how may times delete the file and re-add.

I have the playback issues on my LG TV, MacBook Pro, and all my other devices. I have attached my logs for this issue, and have a screen recording of the issue on my MacBook (which is worse because it gets stuck buffering).

Please help!

A known issue, with temporary work around, on all ApolloLake CPUs (which your Syno uses).

  1. SSH into the Syno (PuTTy or ssh command line from Mac / Linux)
  2. the following sequence
sudo -su root
cd "/var/packages/Plex Media Server/target/lib/dri"
ls
rm  -f  iHD_drv_video.so
ls

From the two listings, you can confirm iHD_drv_video.so has been removed.

Now restart PMS.

Thanks for the help!

I’m having some trouble connecting via SSH - I can login via my user and the admin accounts and use sudo -i to get root access, but I am unable to find the file/directory. Any idea how to proceed?

Type it exactly as I have shown above.

You can also Copy/Paste it.

PS: I did have targets and not target , which I corrected. Apologies as the hour was late.

Hey Chuck,

Thanks for the quick response time! I was able to put in the code, stop Plex and re-start through DSM but the video issue persists. I even updated this morning and put the code in again to no avail. Do you think this might get fixed in a future update? Until then any help is very much appreciated!

If you update PMS, you need to remove the iHD_drv_video.so again.

Each package file is a ‘full update’. It brings all the files with it.

I ran the commands after the update as well and removed the file. Just confirmed the file is removed - I’m happy to share a screenshot of my terminal if that helps? Can I restart PMS from Terminal as well?

I restarted my DS and the issue is mostly resolved - some files still affected but I’ll try playing around with playback settings, thank you so much Chuck!!

Restart PMS from Package Center. it’s the easier step

Has this issue been fixed in 1.18.3.2111? I don’t want to have to do the temporary workaround with every update.

Still trying to fix the intel driver ourselves.

Not an easy thing to do. It looks like a cadence problem but not so.
