Server Version#: 1.19.5.3112 Player Version#: Tuner Make/Model: HD Homerun Connect Duo Guide/Lineup name: Using XMLTV?: Channel number/Name: Running Plex in Docker on OMV (OpenMediaVault) on Raspberry Pi 4 with HD HomeRun. Installed a couple of weeks ago, got it working and recorded a couple of programmes. Just come back to it to record… and it’s not working. Scheduled recordings and attempting to record programmes currently on all fail with “There was a transcoder error” message. Updated plex to latest version, NAS has plenty of free space (over 1TB). Log attached below. Basically I tried a couple of times to click “Record” on a currently playing programme from Guide. Both failed with same transcoder error message. Can anyone help?

I’m seeing the following errors in your logs at the start of the log file you provided: ```auto Jul 27, 2020 19:18:24.377 [0xb6f88970] WARN - [FFMPEG] - Error loading external lib: /config/Library/Application Support/Plex Media Server/Codecs/5f603a2-3204-linux-armv7hf_neon/libaac_latm_decoder.so: failed to map segment from shared object Jul 27, 2020 19:18:24.377 [0xb6f88970] WARN - [FFMPEG] - Error loading external lib: /config/Library/Application Support/Plex Media Server/Codecs/5f603a2-3204-linux-armv7hf_neon/libhevc_decoder.so: failed to map segment from shared object Jul 27, 2020 19:18:24.377 [0xb6f88970] WARN - [FFMPEG] - Error loading external lib: /config/Library/Application Support/Plex Media Server/Codecs/5f603a2-3204-linux-armv7hf_neon/libaac_encoder.so: failed to map segment from shared object Jul 27, 2020 19:18:24.377 [0xb6f88970] WARN - [FFMPEG] - Error loading external lib: /config/Library/Application Support/Plex Media Server/Codecs/5f603a2-3204-linux-armv7hf_neon/libh264_decoder.so: failed to map segment from shared object Jul 27, 2020 19:18:24.377 [0xb6f88970] WARN - [FFMPEG] - Error loading external lib: /config/Library/Application Support/Plex Media Server/Codecs/5f603a2-3204-linux-armv7hf_neon/liblibx264_encoder.so: failed to map segment from shared object Jul 27, 2020 19:18:24.377 [0xb6f88970] WARN - [FFMPEG] - Error loading external lib: /config/Library/Application Support/Plex Media Server/Codecs/5f603a2-3204-linux-armv7hf_neon/libdca_decoder.so: failed to map segment from shared object Jul 27, 2020 19:18:24.377 [0xb6f88970] WARN - [FFMPEG] - Error loading external lib: /config/Library/Application Support/Plex Media Server/Codecs/5f603a2-3204-linux-armv7hf_neon/libmpeg2video_decoder.so: failed to map segment from shared object Jul 27, 2020 19:18:24.377 [0xb6f88970] WARN - [FFMPEG] - Error loading external lib: /config/Library/Application Support/Plex Media Server/Codecs/5f603a2-3204-linux-armv7hf_neon/libac3_decoder.so: failed to map segment from shared object ``` I see you are running Plex in a Docker container… I don’t use Docker for Plex, but I did a bit of quick googling and found [this thread](https://forums.plex.tv/t/plex-does-not-playback-anything/571299) where another user was using Docker and OMV getting similar errors. Does your mountpoint in OMV have noexec set? ---

It isn’t clear, you mounted with **exec** or you have **noexec**? ---

Seconding Tiberius - please verify, because according to the other thread having **noexec** set causes this problem. ---

To provide insight – 1. Codecs are “shared object” library files (blocks of executable code) 2. Linux differentiates between code and data. 3. All files can be read but not all files can be ‘executed’. 4. Shared-object (codecs) require additional privilege (exec priv) to be integrated into the running executable (transcoder). This is where ‘noexec’ stops the operation (security mechanism). ---

To clarify, I thought I had OMV mountpoint set with noexec. After your comments I went back to check. And I hadn’t. Fixed it and now solved. All working. Thank you so much chaps. For anyone reading this with same problem here’s how I implemented suggestions above: **Solution 1: remove noexec from current mountpoint** - SSH into Raspberry Pi - Open fstab (`sudo nano /etc/fstab`) - Under mountpoint(s) delete `noexec`: ![done](https://global.discourse-cdn.com/plex/original/3X/7/a/7a0e8fa6398295161fbf16248d2331b26daa92ce.png) - Save & exit That sorted problem for me. However, not 100% but from reading forum posts it seems that, even if you do this, OMV likes to re-mount with `noexec` after updates etc. and the problem comes back. I _think_ solution is config file stops it doing that: **Solution 2: remove `noexec` from OMV configuration parameters** 1. SSH into OMV Pi 2. `sudo nano /etc/openmediavault/config.xml` 3. Search (ctrl W) for “`mntent`”, a little below it delete `noexec` from opts: ![doing](https://global.discourse-cdn.com/plex/original/3X/8/d/8de44ff863d2b1d35a60fac79de1d6dff677145e.png) 4. Save & exit Hopefully that will stop problem recurring. ---
