Server Version#: 1.42.2.10156 Hello, I noticed a problem today when converting h264 videos to h265 using ffmpeg 7.1.1. I recorded a video from tv. It’s in 1080p and h264 compression. If I move the file “the.voice.of.germany.S15E01.1080p.h264.mkv” to the video/tv folder on my NAS Plex recognizes …

My guess is that the problem is caused by ffmpeg. I updated ffmpeg from ffmpeg-7-7.1.1-1699.10.pm.6 to ffmpeg-7-7.1.1-1699.10.pm.9 this …

Are you rescanning the library after placing the new file into the proper folder? Plex should still scan the file and include it even if the file can’t be played. If the scan isn’t writing, please provide your logs after the scan runs.

H265 is the current standard for my library. It is processing new content without issue. Can you plex dance the file and then post a copy of your server logs?
