Plex stuck on creating thumbnails (FFmpeg issue)

There’s a hidden preference you can use instead of binary-hacking Plex to avoid a broken file.

Video Preview Thumbnail Generation Fails for Some Items

Oh my gosh … There’s a much better way than the binary hacking above. I found a hidden setting: In Preferences.xml, add: GenerateBIFKeyframesOnly="0" By default this setting doesn’t exist, the default value is 1, and Plex uses -skip_frame:v nokey. This is fast but has occasional problems on certain files if FFmpeg doesn’t detect enough keyframes. Adding this and changing it to 0 causes Plex to not use that argument and not skip frames. This is much slowe…
