Some files aren't generating thumbnails, FFMPEG error -22 #61

Hi @breath-prime , I'm not sure why this is happening. We will need debug logs tho. Can you set env var LOG_LEVEL=debug and rerun and then share the logs here? In the meantime, I've got some questions.
Thanks |

Hi @stevezau, Sure thing. LOG_LEVEL=debug was already set. Is there a specific location to pull the log files from outside of what's generated in the console? I'm afraid I'm not seeing that location in the documentation unless I'm just blind.
I just cleared one of my library thumbnails and I'm regenerating them now. Will update with some more console output soon. Thanks for your time/help! |

I already found one thing I need to change: I set TMP_FOLDER to a unique folder instead of leaving it in /dev/shm/XXXXX or assigning a tmpfs volume. For now I'm leaving it as is, unless you recommend otherwise. I'm fairly new to docker setups so sorry for any starter mistakes here. I've attached some console output here with some of the errors. |
|
I just noticed some interesting, intermittent behavior. In my original post, I listed one example error on a library file. This time around, it generated the thumbnails correctly on the same file, while others are having issues. |
|
I know what this might be. Can you tell me the version of FFMPEG please?

Hi @planetrocky, Looks like version 7.0.1 in the container: Thank you! |
|
Hmm, looking at the logs, it works for some files but not others. That’s odd—I’m not sure what’s going on. @breath-prime, do you think this could be a known issue with 7.0.1? I’ve locked it to 7.0.1 for now, but I can upgrade if needed. Also, I see you changed the tmp path. Does it consistently fail on the same files? By the way, are you familiar with Docker? I might ask you to jump into the container and run ffmpeg manually to check the debug output. So first start the container but drop into a shell command Then within the container run the below which failed in your previous run. |

In all my experience (months of testing), FFMPEG will terminate very quickly and you will see the exact error you have. I actually thought I had a bug in my code for a very long time! This is a crash internally in the FFMPEG HEVC packet processor. For example, using this build of Extracting the errors from FFMPEG log, will yield this at the very start of the file.

FFMPEG VersionIt does depend upon the CODEC and container that is causing FFMPEG to terminate. I've a broad range of test-material, and have found different bugs across a range of different FFMPEG versions. Please try ffmpeg version 7.1 (some of my test cases succeed in 7.01, but not all) However don't try any nightly builds from January 2025 onwards, as they will fail a lot on HEVC video. Last known good nightly build of FFMPEGThe last known good version I have is: ffmpeg-2025-01-08-git-251de1791e.exe -version

Hi,
Thank you for the time you and everyone have spent creating and supporting this script.
Current Issue:
I'm currently rebuilding my thumbnails after a fresh rebuild of plex. When I let the script run, some files error out with a -22 error from FFMPEG. When this occurs, no thumbnails are generated and plex just shows black thumbnails for the affected file. It also does not seem to retry with the files so I'd have to delete all thumbnails and try regenerating the whole library again.
Environment:
Example Error:

I can provide any other logs or output you may need.
Thank you!
