Video crashes near the end with a transcode error - but the video is direct playing

Server Version#: 1.32.2.7100
Player Version#: To confirm
Bit of a strange issue. I direct play videos from my media server to my LG TV but reasonably often they crash out with a transcoder error towards the end of the video. At a rough guess I’d assume it’s to do with the credits detection feature, since they seem to drop out around where I’d expect the ‘skip credits’ popup to show.

It happened last night and I finally thought to pull logs. This time it happened roughly 3 seconds beforee the end of the video, during the end roll which wasn’t a big deal but it happens quite often while the meat of the episode is still playing.

Same here on our LG TV for few weeks now. Despite all are Direct Play for Video and Audio with SRT subs (to avoid transcoding). It often happens at the end of the video which is weird since since everything is Direct Play.

I’m not certain yet but If you remove the SRT subs or no subs seems to be fixes it. Either transcoder is now having issue with SRT or what. I don’t know. I’m just hoping it goes away soooner…

You guys seem to have a different way to reproduce the error, but maybe it is related to this: LG C9 TV: Conversion failed. The transcoder exited due to an error happening occasionally - #68 by cremor

Same problem. Here are the crash logs from MacOS
