AVPro Video player delay #566

Closed mykr13A closed 3 years ago

mykr13A commented 3 years ago

Hi,

I use the AVPro Video player to play a 360 live streaming video on Unity. I noticed that when I start the video player it takes about 8s to load the video and the live streaming video I watch has 8s delay. That is the video player starts, it takes 8s to show the live streaming video and when it shows the video, it is 8s back in time (as long as the delay is). The same delay appears when I run it in Oculus Quest. How could I decrease the delay of the video player? Are there any settings?

You are seeing the delay on both Windows and Android? If so, it sounds like the problem is at the server/stream end as the two platforms use completely different APIs in AVPro Video.

Are you able to provide a link to the stream?

Unfortunately, I cannot provide a link of the stream due to privacy issues. Do you have any idea why this is happening? Or what could I do to my server to reduce this latency? I use an rtsp protocol. Is there any case that the protocol causes the delay?

I would say 100% the delay you are seeing is the due to it being an RTSP stream. RTSP streams always seem to have a lot of inherent lag compared to HLS etc. If you google 'rtsp delay start' you might find some tricks on server setup to minimise the delay.
