Error while transcoding one particular file

Server Version#: 1.40.1.8227
Player Version#: All

In any plex client, I get a Playback Error that says “Conversion failed. The transcoder exited due to an error”.

Here are the errors/warnings/info logs that are relevant inside plex:

Did some more digging and, for some reason, it seems I can’t read from the file. I’m not sure why. Possibly plex (or something else) is locking it?

I can perform this command on any other file and it spits out 5 bytes of data but fails on this file.

lslocks does not show this file as being locked

I copied the file with a new name, deleted the original, then put the name back and now it works. I still have no idea why. The permissions and everything are exactly the same. We’ll see if it sticks.
