Question / Help OBS Live Streaming to Facebook Live: video recorded for later viewing has audio off-sync

[massimiliano_c]

I'm using OBS Studio 21.1.1 from a MacBook Pro 15 2016. I'm streaming different cameras to Facebook Live. I'm correcting the off-set of audio/video sync via OBS. While streaming live, the audio is correct, and the users from their phone can view and listen audi/video in sync. As I stop the streaming, Facebook renders the video for later viewing. As i watch the video in my video library on facebook, the audio is off-sync.

Any suggestion?

Here's my OBS steaming config:

Custom streaming Server
x264
CBR
3500 bitrate
1280x720 30 fps
audio 48khz mono 128
Keyframe every 2 sec
I tried also 44.1khz audio but I have the same issue: live streaming in sync, video for later viewing out of sync. Thanks!

Did you ever figure this out? My mac livestreams are great until X minutes in then the audio gets garbled till its unusable. wondering if its the same issue as what you had?
