Topic: Audio-video desync, conflict

Hi everyone,
I've just read trough this forum for 4hours straight trying to fix my issue. I've recently install SVP 4 to get 60fps for streaming media, it's awesome ! But it has launched me into an audio-video sync wormhole...

Before SVP instal:
I'm using VLC to stream my media. As I use a projector, I stream video trough HDMI cable and my audio through Bluetooth as I'm using my BT speakers. Audio and video were a bit out of sync and I use native sync tool directly in VLC parametres and it worked flawlessly (320ms).

Now that I have installed SVP, it fixes this delay to 250ms. I found this parametre under SVP parameters prefetch>vlc_delay but no matter how I change this value (+/-250 to 0), nothing in the audio-video sync change when I play my file from VLC.

I also tried to add a delay, either audio or video, through ffdshow config parameters but that get bypass as well.

I'm running out of idea what is the issue and how to resolve this. There is probably a conflict of parameters somewhere on my PC but I can't find which or where. Pls someone help me, it's very frustrating.

Re: Audio-video desync, conflict

this is the way VLC filter works - it overrides audio/video sync value and shifts video timestamps accordingly, to be able to buffer a few frames inside the filter.

for now you can't do what you want in VLC + SVP
still you can use any other video player...
