Hi, it depends. There is an option to delay video in relation to audio. In theory it can be used, depending on actual situation. My questions are:
do you use audio as well or only the video?
what is approximate duration of the delay?
If the responses is "no" and something below 1 second, you could use something like:
uv --audio-delay -AMOUNT_IN_MS
I'll explain – in this mode audio or video is delayed given amount of milliseconds, in case of negative value, video is delayed (as we cannot present video earlier). My second question is because I am not unsure if this trick scales well beyond let say few second; other approach will be perhaps more eligible.
Audio is coming to destination by different route and is around 1 second latter then video. Audio is highly processed by high latency ai plugins in daw and thats reason why video is receiving sooner then audio.
Thanks for the info, so we'll try to add video delay postprocessor. Adding the delay to -1000 ms as I proposed above may or may not work but it is slightly on a borderline of what is rather misusing that parameter.
I've just added the delay video postprocessor that might be able to do the task, example usage:
uv -p delay:sec=1.5 -d gl
The code should be built in continuous in few moments.
Thanks
Hi, I am looking how to delay video in ultragrid as obs video delay filter is unstable and get always different number. I see that ffmpeg has that type of parameter.
Thanks
