Server Version#: 1.17.0.1709
Player Version#: 4.8.1
Pretty straightforward. Hardware transcoding worked perfectly until the upgrade to the latest version. This needs to be resolved asap. Running the latest windows version and latest nvidia driver. Transcoding works perfectly still in all other apps. Issue is exclusive with Plex.
It also does not failback gracefully to software transcoding. Simply breaks until I uncheck hardware transcoding and then everything works fine.
I noticed hardware transcoding issues as well. Mine is specifically with nvidia decoding MPEG4 video content. Everything else seems to work as intended.
Other users have reported getting their system working by finding the proper method of updating or reinstalling their GPU drivers for their windows version and hardware combination. What Plex might be doing is exercising broken aspects of your install that have not been touched before. And those would be malfunctioning due to Windows’ poor install and update system. Good luck!
Just upgraded from 436.30 to 436.48 and the issue is still occuring sadly.
Had previously clean installed 436.30 standard.
Don’t want to downgrade further as Windows update will then force install older DCH drivers for some reason.
I’m using debian and still have the problem so I don’t think it’s a windows driver issue.
Well 436.48 has references to Video Code SDK 9.1 here:
They appeared in 436.30 here also that didn’t work:
I don’t recall having this issue prior to then, not sure if your debian system lines up.
Or if back then I also had an older version of the server installed as the changelog also references quite a few changes to the transcode as well.
I’m using a GTX 970 and an older driver version from what I recall. My issue only seems to be with decoding mpeg4 content, and prior to a recent version of PMS nvdec wasn’t natively supported so I used a workaround which specifically excluded mpeg4 from decoding.
Is your issue with all video files or are there certain formats that still work?
Not OP, but I came here because I had issues with transcoding only mpeg4 content.
Is there a way to exclude mpeg4 content only until this is fixed?
I should have said at the start, rigorous analysis takes a sample, logs, and steps to reproduce.
We’re not there yet, but I feel the pain.
So in the meantime, MPEG-4 covers a broad range of possible encodes.
Your local media is unique. If you get demos from the Kodi archive
or jell.yfish.us that demonstrate the issue, that’s even better.
One topic per person per issue is also reasonable.
I’ve got the same issue on my plex server.
Here’s my ticket with logs too:-
The Beta channel update that just released fixed the MPEG-4 issue for me. I’d encourage those who have this issue and Plex Pass to go grab it.
Same all good again
Agreed. I see in the patch notes that (Transcoder) Fixed H263 hardware decoding (#10580).
Seems to have fixed mine too.
I use MS remote Desktop to access my server and apparently that can cause issues on HW transcoding.
