How To Delay Camera On Obs
ane.5 Second filibuster of RTSP video feed into OBS
Our church simply bought the 20x -SDI photographic camera. Nosotros currently apply OBS to alive stream our services. The trouble we are having is rather than just the normal couple hundred millisecond filibuster in the video feed, we are having a latency of about i.5 seconds. No corporeality of adding latency to the audio can seem to compensate for such a big lag. We have brought the RTSP stream into ONVIF, IP Capture Viewer, and even downloaded a trial of vMix, and in all of them, the video feed was virtually existent-time or only a few milliseconds delayed.
It seems to be something with OBS. Has anyone else ever encounter this trouble, and take yous found a solution? Thanks.
Hello Dwight,
This is something we have been hearing and seeing recently. Information technology turns out OBS leverages VLC for pulling in RTSP feeds. Whether you bring them in as a media source or VLC Video source. And it seems like the aforementioned issue occurs in the latest version of VLC. We are in the process of testing things out with older versions of VLC to see if that solves the issue. If we detect anything that tin fix this delay in OBS I will achieve back out on hither.
Thanks for letting me know! Will be watching for a resolution!
Any update on this issue? I'g also experiencing something similar. Wondering if OBS has this limitation, should we look at other options similar Wirecast will have a better functioning.

Hi James,
Yes, this appears to be becasue OBS leverages VLC to practice the RTSP feeds. This adds a skilful bit of additional latency that would otherwise not exist in that location in Wirecast or Vmix. You can ever go a trial of Vmix to test it out and see if it shows less latency for you.
We are having a similar issue using vMix, so it isn't strictly an OBS trouble

Hi Lee,
IP latency tin come from a number of different sources and the means that VLC, OBS, vMix implement use of the FFMPEG solution.
I would be curious with your setup in vMix how much latency you are seeing and how the stream(southward) are existence configured.
Please run into an case of achieving the lowest possible latency within vMix, outside of using NDI, for our RTSP feeds.
Note that we would non recommend running a professional person production with no buffer every bit shown above.
What this should enable though is for you to come across, without buffering, how low of latency is possible given the electric current PC, Network, etc...
One other thing to be aware of is the x264 decoder selected within vMix settings can likewise impact the final latency experienced.
If you have whatsoever additional questions relating to this or otherwise delight do not hesitate to return to the forums.
Has anyone figured out a set up for this latency effect? I had my sound dialed in and just used presets, but now the latency seems to be variable and this week was almost 3000ms instead of the 1100ms information technology has been since I fix it all up.

Howdy Josh,
While I cannot speak to the exact latency you volition see via OBS I can likely assist with the "drift" issue you are experiencing.
On our network I typically see latency effectually 800ms - 900ms in testing in OBS using the VLC input option for RTSP.
Our network is a Unifi solution, summit to bottom, that uses the post-obit setup guide to for configuration for IP video
Unifi Setup Guide for mDNS and Multicast
In the knowledgebase entry shared beneath you will acquire how to leverage the NTP options on the camera, you lot PC and network to minimize video drift and allow for better synchronization of multiple cameras and audio feeds.

If y'all practise not encounter the NTP option on your camera delight proceed with updating the firmware using the PTZOptics Firmware Finder.

If you combine this tutorial with the audio synchronization test you should notice a much more than reliable presentation for day-to-twenty-four hours use with fiddling to no modifications required.
We hope this information is helpful towards improving the synchronization between audio and video for your productions
