Video playback issue on High Sierra
BrownBear:
Hi Guys,
I upgraded to High Sierra last night and experienced some issues with video playback ?. Every time I tried playing a video/movie it starts to play and then JRiver freezes (picture and sound stops playing). Pressing any buttons does nothing. Eventually the OS puts me back on the login page and I need to log in again. Tried updating from build 41 to 52 (clean install) but still get this problem. Playing music works fine, it is only videos.
After some additional testing it seems to affect MP4 and MKV files assuming it might be something to do with H264? Videos with other encoding seems to work. Any idea what could be causing this? Everything worked prior to the update.
Thanks in advance for any help/guidance.

I thought your earlier report indicated that your movies were on a NAS share. Have you tried with a local file (on internal or USB disk) ?
I assume your computer rebooted at least once during the OS installation process. Have you tried rebooting again?
What kind of Mac are you using?

I have tried with a some local files (copied over from NAS) and it still gives the same problem. Tried a few MPG and AVI files with XVID and MPEG-2 encodings and they work. MKV or MP4 seems not to work. Tested with a view videos downloaded from youtube as well with no success.
Yes it did reboot during installation and I have rebooted a few times afterwards during testing and after reinstalling JRiver.
I am on a Macbook pro 15" late 2013 model.
I am able to play these videos using quicktime and VLC.

Interesting. I did a little bit of reading and found that some people are experiencing high CPU utilization after the upgrade to high sierra. You might open the Activity Monitor (Applications > Utilities > Activity Monitor) and switch to the CPU view and see how much CPU is being used and how much is free.
A "normal" system will typically have at least 80% CPU free (only 20% being used). Mine is generally not even that busy. It's usually around 90% free (only 10% being used).
I saw reports of a process called trustd taking up lots of CPU.

I can see there are 4 instances of the trustd process but they are all idle. My machine is 90% idle. Usually the fans will kick in if the CPU load is high.
The strange thing is that the videos start to play for 3-4 seconds before my machine freezes. I did change the config so that the app does not jump to the display view when the video starts, so I see it starts in the bottom left window. This only happens when trying to play videos through JRiver.
Does video playback work for you on High Sierra? Hope I am not the only one with this issue.
