Describe Your Environment

connortechnology commented 1 month ago

Works for me although I have seen some weird behaviour with the stream sometimes, not dependent on fps. What doesn't work is Stills mode. Used to be we had a stills mode where it was basically paused and if you clicked on the image it would update.

Seems to me we may need rate options less than 1. Like update every 10 seconds or every minute.

Hm. Additional analysis is probably required.

I didn’t even know what kind of regime this was, but now I understand. Perhaps it should be removed from the selection?

Maybe. Just tried it. When the FPS value is less than 1 (as with =1), a black screen with the words "Waiting for capture" appears, and then a picture appears, then again a black screen and again a picture. Not pretty at all.

Yeah I have seen that behaviour but cannot at this moment reproduce it. Log analysis will be required. Waiting for capture means that zmc isn't decoding.

If "decode = All" - the black screen appears less frequently, if "decode = On demand + key" - the black screen appears more often. And it’s like this on all my cameras... There are no errors in the logs, I did not enable debugging.
