Server Version#: 1.42.2.10156 Player Version#: 4.147.1 Hello, I recently started to have the “Conversion failed. The transcoder exited due to an error” error on a single TV series, the file would not start or will crash after some time and won’t be able to be played again. I saw those two errors in the logs : Nov 16, 2025 10:21:31.497 [140046520761144] ERROR - [Req#1ad0d9/Transcode/hud0dxklpnqe83a5rkwumcxn/6e0c0559-d919-4f24-a491-03d357fd55f2] [eac3\_eae @ 0x7f804a314ac0] Cannot group in blocks of 6!

Did you check your inotify values? > [@Synology FAQ - Questions, Answers, and How-To's](https://forums.plex.tv/t/synology-faq-questions-answers-and-how-tos/490215/22): > > FAQ 16: Increase the number of folders Plex can monitor Applicable to all supported versions of DSM. When the Linux ‘inotify’ table fills up, this will cause when Plex to stop automatically detecting new media you add to the server. It will also manifest when there are transcoder problems with Dolby audio codecs. Linux has a default table size which is static. We can increase this at will. On some versions it’s 8192. On newer kernels, the default is 65536 folders. This is easy to incr… ---

The blocking fixes (multiples of 6) was implemented in PMS several releases ago. May I get a sample of the file to test here? (I think it’s a damaged / incorrectly encoded media file) ---

Hi, thank you for answering ! How am i supposed to provide a sample of the file ? Is the blocking fixes important or can it be turned off ? sometimes plex can play most of the file without any problem so i’m wondering… ---

Sorry! I forgot to give you the link for creating a [sample file](https://support.plex.tv/articles/201035968-generating-sample-files-from-media/). [https://support.plex.tv/articles/201035968-generating-sample-files-from-media/](https://support.plex.tv/articles/201035968-generating-sample-files-from-media/) We can’t ‘turn off’ the blocking. It’s part of the Dolby-provided encoder. Dolby requires we send it audio in groups of 6 audio segments (blocks). It then converts the audio to the output format needed. I’m sending you a link so you can attach the file (if small enough) or a download link where I can get it. ---
