While testing to see if not using the buffer would alleviate the stream resetting issue (which it didn't as I mentioned in a different thread moments ago) my viewers found there to be a fairly severe delay in audio in relation to the webcam video.

I think there may be some webcam issues in general as sometimes the webcam is silky smooth when using OBS and other times it's a bit of a mess (this is regardless of webcam settings and identical lighting in the room).

If you want to see the syncing issue here's an example:

Could I see a log file? Just want to check something in there to see if it's what I think it is (timestamping related issue)

Hm, very interesting. Your mic is still behind the video despite the fact that I implemented specific timestamping code for microphones to prevent this from occuring. Definitely not the video's problem here. This is most interesting. Did you create this via the MP4 file output, and then just upload it to youtube? MP4's currently have a weird sync issue at the moment I'm still trying to pinpoint.

If not, and this was happening on a live stream as well, then maybe some time you could come around the chat and help me determine what the cause is if none of those things are the case and the mic is definitely off

It's strange in that it's fine today (according to the viewers anyway). That video was uploaded straight from twitch and I THINK their storage is all in FLV. It was there during the stream either way according to those watching.

Yeah I pop in to chat every now and then when I'm doing my emails and stuff in the morning but I think you don't get up usually until another couple of hours after. I'll try and pop in when I know you're up and we'll see if we can hammer something out.

hm, so basically the problem only happens on youtube after you upload it? do the twitch vods show any problems before that? stream is okay?

Nono, I'm just commenting on how it is at the moment. I'm actually live right now hahaha.

I'm saying it happens on the live stream and carries over to the archive so it's not a rendering issue or something.

Wow threads get buried fast.. Could you check out 0.463a test 4, nova? Or anyone? Could anyone who had mic sync issues in 0.458-0.461 test out 0.463a test 4 and tell me if it fixed the problem or not?
