Hi Mark,

I can confirm that vMix should reconnect to rtsp streams in the background, so it is certainly strange that everything is hanging.
Might be best to drop us an email to info@vmix.com.au and go to Settings -> About and click Send Support Report (preferably with the preset open) so we can investigate further.

Thanks,

Martin

If possible, could you email us the log and xml files from the replay folder for that session.
I have been running tests with rtsp disconnecting and have not been able to recreate any hanging (other than the obvious temporary freezing of the rtsp camera itself)

Thanks,

Martin

This sounds very very similar to what I am getting
Mark

i am having the same problem with vmix17, still haven't tried 18. If I loose an rtsp camera (and having at least 7 wireless cams it can happen several times a day), recording will stop and vmix hangs for around 10 secs. This didn't happen up until the first update of v17. If the camera is imported via vlc-ndi vmix will not hang. I will try with v18 soon.

unfortunately the proble is still with us on 18.0.0.61

tried only with 1 rtsp camera and 2 video files playing in loop.
The first time I only disconnected network cable from camera and waited for connection error in vmix, the video file playing and the other overlay video were still running. I reconnected the cable and the camera went back online without problems.
I then removed power from the camera, and after around 5 secs, recording stopped and got error message. Video playback halted as well..

my system is:

Intel i7 3770 3.4G
16Gb ram
Nvidia GTX660 with driver 10.18.13.6869
2 x Blackmagic Intensity Pro PCI cards

no replay. Here is a video with the problem.
As you can see only 1 rtsp cam and 1 video file and ticker.
Camera is a Grandstream but I can't give you exact model at the moment. But in previous tests with V17 camera model was irrevelant, it happened with every camera I had (Grandstream, Vivotek, Auvidea HDMI board encoder)

@ thepelell

Perhaps totally unrelated, but I couldn't help but notice that you were recording simultaneously.
What were your recording settings and hard drive specs?
I've had similar "hiccups", that to me were more hard drive related (read/write timeout sort of thing) when vMix CPU and/or GPU are dealing with matters at hand, in your case, Input signal loss while playing a video with ticker overlay and recording simultaneously.

I tried the same exact configuration without recording and had the same problem. When vmix tries to reconnect the rtsp camera it hangs badly.

Thanks for the reports, the MultiView being on was what I needed to track down the bug.
It's to do with an obscure bug in the .NET Framework, but i'll be able to release a fix for it in the next update due out soon.
