Hello,

recently i have noticed that my plex server is not using hardware transcoding anymore, no matter which type of video content i want to play. This way even watching a 576p MPEG2 Video that has to be transcoded into h264 for the web app, my CPU gets 100% utilized and the transcoding is still very slow.

It seems like it’s the exactly same issue as je1117 already wrote in this Post:

Unfortunately it has been closed a few days ago so i couldn’t reply to it. Like in this post, i have also just noticed it very recently because i wasn’t playing a lot of videos and i usually don’t install updates very often. My server is running on an i5-4570T which has the same iGPU but less cores, so it makes the software transcoding even slower. I also had to install version 1.41.5.9522 for the hw transcoding to work again, i tried a few other versions inbetween but anything newer would not.

I hope this gets fixed again in a newer version. I also don’t know if it only affects this specific iGPU or maybe others too.

Any updates to this topic? I have just tried updating my server to the latest version (1.43.0.10492) and it is still not working (or rather again, as it was working fine with version 1.41.5.9522). It always just transcodes with CPU in the newer versions. I this doesn’t get fixed, i have to stay on that version forever but i suspect that might not be compatible someday anymore…
