Plex may occasionally show various errors when you try to play a video. For example, one of the most common error messages reads as follows: “An error occurred while attempting to play this video.” The problem is that the error persists even after restarting the app. Let’s see what else you can do to troubleshoot this problem.
How to Fix Video Playing Errors on Plex
Play Smaller Videos
First of all, make sure to update your Plex Media Server and app to the latest releases. If you’re getting this error on an Android device, go to Settings and select Quality settings. Then enable the option that allows you to play smaller videos.
If you’re experiencing bandwidth issues, Plex will try to preserve the video quality by playing the content as a smaller video. Keep in mind that video playback may still occasionally pause if the connection is painfully slow.
Tweak Your Audio Settings
Other users fixed this problem by changing their audio settings. If your movie has a PCM 5.1 audio track in it, switch it to DTS 5.1 and check if the error goes away. If the issue persists, try switching to AC3 and check the results. Switching to DTS 5.1, AC3, or anything other than PCM 5.1 did the trick for many users.
Several users confirmed the issue went away after disabling the Audio passthrough setting (Settings → Advanced → Player). Use this workaround as well and check which solution works best for you.
- Go to Settings, select Advanced and turn off the new player. Reverting to the original player worked for many users.
- Go to Account settings, Advanced, and disable H264 maximum level. This solution also allows you to keep the default player.
- Try turning the subtitles off and play the problematic video again.
If Plex fails to play your videos, disable the new player, as well as the H264 maximum level setting. Additionally, play smaller videos and switch PCM 5.1 audio tracks to DTS 5.1 or AC3. Are you still experiencing the same error? Let us know in the comments below.
