2BTSquared 5 Posted June 1, 2022 Share Posted June 1, 2022 Emby has recently developed audio/video sync issues. It appears to effect recorded TV. I tend to watch shows while they are being recorded. But I delay starting playback by 20 minutes or better so that I can fast forward through the commercials. Audio/video seems to be in sync at the beginning of playback but becomes more more out of sync as playback progresses. Half way through an hour program it becomes unwatchable. The problem manifest when playing back with Emby Theater (3.0.15) or the web app. I've attached the most recent log files. Let me know what other information I can provide or is needed. embyserver.txt ffmpeg-remux-df0a0abb-c6be-4961-ba7d-ac5dd50fea34_1.txt ffmpeg-transcode-d476f9c9-24a6-4eb4-8f89-d130c4cc34eb_1.txt Link to comment Share on other sites More sharing options...
2BTSquared 5 Posted June 3, 2022 Author Share Posted June 3, 2022 Another night. Another episode recorded with audio and video out of sync. Played it back with VLC to see if the player was the issue. Nope. Audio and video out of sync with VLC too. Link to comment Share on other sites More sharing options...

softworkz 3324 Posted June 4, 2022 Share Posted June 4, 2022 Please try to replace the ffmpeg in the Emby system folder with one of these and see whether it makes a change. ffmpeg_versions.zip Link to comment Share on other sites More sharing options...
softworkz 3324 Posted June 4, 2022 Share Posted June 4, 2022 Could you please try to replace (after backup copying) hls.min.js with this version: hls.min.js.zip It's in the dashboard-ui/modules/hlsjs folder of the server installation You may need to refresh the browser cache in edge and F5 refresh to be sure you get the new version when trying playback.

softworkz 3324 Posted June 4, 2022 Share Posted June 4, 2022 If none of the above helps, we should collect some data from the source and output files. Could you please try the following steps? Prerequisites Update to Emby Server 4.7.2 Install the Diagnostics Plugin from the catalog Reboot EDD Generation Go to "Diagnostic Options" on the server dashboard Scroll to the bottom where it says: Diagnostic Data Generation Check all three boxes Save Reproduce the problem Link to comment Share on other sites More sharing options...

I'm always skipping through the commercials. When doing so the problem remains. The recording starts out fine, but as playback progresses the audio/video sync issue begins to manifest and gets worse.

The zip file contains two versions. I'll chose what appears to be the newest (2022-01-14). I'll backup the current version of ffmpeg.exe in ...AppData\Roaming\Emby-Server\system and replace it with the version in the 2022-01-14 folder. If my assumption is correct, the next scheduled recording is on Monday evening. I'll wait and review that recording and report back. If this step fails, then I'll move on to replacing hls.min.js. If my asumption is incorrect, and you want me to go ahead and replace hls.min.js now, then let me know. Thanks for the help. Update... I guess I could just schedule a recording of something today as a test case and see what happens. Edited June 4, 2022 by 2BTSquared Link to comment Share on other sites More sharing options...

That's fine, you'll need to redo the replacements. Yes, I meant to try one at a time. The hls.js affects watching in the browser (do F5 and clear the browser cache after replacing). I forgot to ask: when the recording is completed and you play it then, do you see the same problem? Link to comment Share on other sites More sharing options...

Unfortunately I didn't catch to the part about a short recording. Tonight's recording was for the whole show/hour. Roughly a 1.7G file. I could try to do a short recording, but I'm not sure the issue would manifest. Usually it doesn't start going sideways until about halfway through playback of the hour long episode. I'll give it a try and see what happens. hardware_detection-63790227304.txt embyserver.txt ffmpeg-directstream-56eed4ec-739f-4895-9732-5ba304e868d9_1.txt Link to comment Share on other sites More sharing options...

Thanks. Is there suppose to be a install file here, or am I just supposed to replace the contents of the system folder with the contents of this system folder?
