Just be aware that this log file is not from playback on the LG TV.

Sorry it was another device's log. Forwarding issue doesn't throw ffmpeg log file. I tried again now with transcoding and without transcoding. Here is the new log file, mb it helps you.

embyserver.txt

Is it just the one file that has this issue? I suspect there might be an issue with the file encoding

There is no ew encoding log file. Only embyserver.txt.

I check old logs and found this but idk it related to LG WebOS because it not includes App info (or i can't found).

I mean the actual file itself that you are trying to play.  If it hasn't been made correctly then you can have issues with things like ff/rew.  That's way I ask if it is just one file that has an issue or all files.

It happens on entire season videos but I downloaded all from same source.

Blacklist that source and buy the media and rip it your self.

Like most things in life " If you want it done right, do it your self "

If it is just that season from the one source then likely it has not been correctly encoded at creation.

If other files/sources play correctly, then that would mostly confirm it.

Yes it related to video file. I tried another 4k hevc video and it is working perfect.
