Server Version#: 1.20.1.3252-a78fef9a9 Player Version#: Version 4.34.4 (shiled, Windows PMP, Web browser, etc) For the past few months users of my server have said it’s un-useable due to constant transcoding errors. Lately, I’ve been having them several times a day on my local network as well. I currently can’t watch a 20 minute show without it erroring out 5-6 times during playback. Also, if I leave the tab open for [http://127.0.0.1:32400/web/index.html](http://127.0.0.1:32400/web/index.html) it eventually becomes a completely black screen and I need to double click the plex icon in my task bar to regain access. I’m attaching my logs and have tried every setting I can think of in the transcoder section. ---

Can anyone help me please? Plex used to work for years, but is completely broken now. I’m not sure where to look in the logs… ---

There are many FFMPEG / CUDA out of memory errors. Also, Plex is not always recognizing the GPU. See log entries below. Which NVIDIA card are you using? Maybe re-installing the Nvidia drivers would help. Also, I’m not sure if it is relevant to your transcoder problems, but Plex is constantly re-analyzing the same iCloud photos. It detects a rename, which kicks off an analysis. For example, it reanalyzed IMG\_4158 three times between 12:12:51 and 12:26:19, a little over 13 minutes. For all your pictures, there were 9018 renames, and corresponding analysis, during the same 13 minute time period. I don’t use iCloud Photos or have photos in my Plex Server. But maybe your system is so busy analyzing photos it has trouble streaming/transcoding movies & shows? * * * Out of memory errors `Sep 23, 2020 12:15:29.032 [47588] ERROR - [FFMPEG] - InitializeEncoder failed: out of memory (10)` `Sep 23, 2020 12:18:47.055 [39480] ERROR - [FFMPEG] - -> CUDA_ERROR_OUT_OF_MEMORY: out of memory` Recognition issues `Sep 23, 2020 12:13:17.608 [37952] DEBUG - TPU: hardware transcoding: enabled, but no hardware decode accelerator found` `Sep 23, 2020 12:13:17.608 [37952] DEBUG - TPU: hardware transcoding: final decoder: , final encoder:` `Sep 23, 2020 12:14:32.887 [18888] DEBUG - TPU: hardware transcoding: final decoder: nvdec, final encoder:` Picture Analysis ```auto Sep 23, 2020 12:26:19.613 [49048] DEBUG - We found a hash match for [C:\Users\peloq\Pictures\iCloud Photos\Downloads\IMG_4158.jpg] which was [C:\Users\peloq\Pictures\iCloud Photos\Downloads\IMG_4158.jpg].

Thanks for the response. I’ll try removing photos from Plex altogether. My video card is a GeForce GTX 1080 Ti and the driver version is 456.38 (latest). How would I resolve the out FFMPEG / CUDA out of memory errors? I’ve reinstalled the drivers and they say in the geforce app that they’re the latest versions. ![image](https://global.discourse-cdn.com/plex/original/3X/f/6/f6a0b859e4dfc25eb857ba432bd9f64b151769aa.jpeg) ---

Leave hardware acceleration enabled. It looks like you have an i7-7700K CPU. It is more than capable of transcoding multiple 1080p streams w/o hardware acceleration. However, hardware acceleration should work. Disabling it would be a workaround. Let’s see what happens after you remove the photos from Plex. Let’s try this: - Once Plex has finished removing the photos, reboot your PC (since you re-installed the drivers). - Wait 2 - 3 minutes for Plex to finish startup. - Play a movie or TV show and force a video transcode. - Let it run and see what happens. - If the transcoder fails, then pull the log files. - Even if it doesn’t fail, still pull the logs, to make sure Plex is using the 1080 Ti for transcoding. * * * Edit: FYI, the log entries in the earlier post are from `Plex Media Server.log` (wraps to .1 to .5) in the ZIP file. If hardware acceleration is working correctly, you’ll see final decoder = nvdec and final encoder = nvenc in the entries with `TPU:`. ---

Ok, I rebooted and then tried playing a movie from my mobile device off of the wifi. It errored out about 15 minutes in, logs attached.[Plex Media Server Logs\_2020-09-25\_15-18-12.zip](https://forums.plex.tv/uploads/short-url/jwp2xDaiSSOpBZRFKAkdfEE0nuq.zip) (5.7 MB) ---
