Some videos don't play after recent 1.40.2.8395 update!

MAC Server Version#: 1.40.2.8395

It seems that right after this recent update, I started having problems with some movies and videos not playing even though, only days ago, there were no problems playing any of these videos or movies.

I am streaming within my own house, on same network, and playing on an Apply TV device (ATV), or on a Samsung TV (STV), or even trying to play the movie or video with a Plex Player or Web Player on the very Mac where the server is installed… some movies play no problem, but others don’t, even though they played prior to update…

I don’t get any error messages on the ATV or STV, it simply keeps spinning a wheel and never plays. But, when I use a Plex player or Web player on my Mac where server is running, it gives me this error: Conversion failed. The transcoder exited due to an error.

I’m not sure if its a codec issue, or a probem with the current Server version, but I am struggling to find a solution, or figure out how to fix it. I’m noticing it appears this problem ONLY exists with x264 encoded video. I downloaded a few duplicate videos created with x265 codec, and they all play. Only the x264 videos are having the problem.

I’m not a solid tech guy, so need you to walk me through it, thanks. Much appreciated.

Same here. I am using a Synology NAS (DS1019+) which has hardware transcoding, but most (not all) .mp4 movies and TV series exhibit the same behavior you are describing. I think PLEX broke the .mp4 transcoder in the latest version. Unfortunately for me, Synology Package Center will not allow a roll-back on PMS versions so I am stuck until PLEX fixes the issue.

Thanks for your comment.

Is Plex aware of this new problem? or do they just ignore it?

It’s THIS kinda stuff that makes people abandon Plex and use other software.

I’m not sure but since this is a beta version ( Version 1.40.2.8395) I don’t know how quickly they will release a new version…hopefully soon!

Same problem here. I rolled back to 1.40.0 and everything start to work again. (Server-Windows)
Videos works on computer (chrome) but don’t won Plex app (Android) and Plex for Roku.
I don’t know how to report this bug to help them fix this

Where did you find this older version? I can’t seem to find it anywhere, and when I go to the Plex Media Server downloads page, it seems to be locked onto Beta downloads, and I can’t toggle it off.

I’m running 2 servers, one on a MAC and the other on a Synology NAS , I would love to roll back to an earlier version. I checked my settings on both servers, and I am configured for the Public channel, not the Beta channel, yet I somehow this problematic Beta release is installed.

Since i’m on Windows, I used the update folder :
C:\Users\YOUR_USERNAME\AppData\Local\Plex Media Server\Updates\

Ya, I figured out how to roll back my Mac, but sadly I cannot do the same method with my Synology NAS which is updated manually, and I certainly didnt know the update was a Beta.
