Version 1.16.5.1554 works just fine, a while back I updated to 1.18.2.2058 and Live TV and DVR recordings were choppy and pixelated, I switched back to 1.16.5.1554 and once again things worked just fine. I’ve now just tried 1.18.5.2309 and once again Live TV is unusable.
Is this a known bug? I the HDHomerun still supported?
You are going to have to provide a lot more info because it works for me all day and now, no changes from previous versions,
Details:
Plex Server:
Intel NUC - Celeron J4005 CPU @ 2.00GHz, 8G memory and 256G SSD
HDHomerun. Plex has HW assist enabled. Server is running Ubuntu Server LTS
Linux plex 4.15.0-76-generic #86-Ubuntu SMP Fri Jan 17 17:24:28 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
Viewer:
Used mainly by AppleTV Plex app but also see the same chop and pixelation in browser viewer on laptop.
Using the 1.18.5.* release the CPU usage during playback is about 25%, with the 1.16.5.* release the CPU usage topped out at about 75%. As I stated before 1.16.5.* records and plays live TV just fine but after upgrading to 1.18.* releases it’s unusable. I have tried removing the HDHomerun device and re-adding it but that did not seem to help.
Any suggestions would be appreciated.
With your CPU use high at 75% under 1.16 it doesn’t seem like you were using hardware transcoding. 25% under 1.18 still seems high if hardware transcoding is being used… your CPU has an Intel UHD 600 GPU. Have you tried turning off hardware transcoding to see if the choppy/pixelation goes away?
Wow, that worked! Thanks.
So does that mean that the transcoder driver does not work with the Intel HW?
They have been constantly updating the transcoding system to fix bugs like yours on differing systems, perhaps some of those have affected your system and caused hw transcoding to be enabled where before it wasn’t.
You may want to give the build (1.18.6.2349) linked in this thread a try:
I realize thread title specifically mentions Synology, but the problem (and fix) can manifest on any Linux install which uses Intel Quick Sync Video for hardware accelerated transcoding. I’ve tested on my Linux server and it corrected the issue.
Using it, you should be able to re-enable hardware acceleration and have good results.
Thanks. I’ll give that a try.
