Finally I copied the compiled libraries from /usr/local/lib to /usr/lib/plexmediaserver. old extension to libopencv_core.so.2.4 and libopencv_imgproc.so.2.4 in the/usr/lib/plexmediaserver folder. $ mkdir build & cd build & cmake -DENABLE_SSE3=OFF. To fix I downloaded the opencv library, Unpacked the zip file, switched to the unpacked opencv folder and compiled it with the following options: In my case the processor didn't support SSE3:įlags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 syscall nx mmxext fxsr_opt lm 3dnowext 3dnow rep_good nopl lahf_lm vmmcall After doing some googling, it looks like the opencv libraries they pack with the newer versions of Plex require SSE3 instructions. I didn't want to run the old version for security reasons. So I went all the way back to 0.9.8 and that worked. I tried version 0.9.12 and it had the same issue. Their download page seemed to force you into one version. ~/Downloads$ sha1sum plexmediaserver_1.-1bef33a_bĨ64652a94a5d3cc31991407ad2267d8d775b3908 plexmediaserver_1.-1bef33a_bĭumb question, but I was going to try getting an older version of it, but I couldn't find an older version on the Plex site.

If the 1st 2 things are correct for your system, I'd try a different release of plex. Google isn't helping based on the invalid opcode. Have you verified the download isn't corrupted? Use the checksum.
