Suddenly constantly gettinga very low quality video in iOS app
Completed
I have Hikvision DS-2CD63C5G0-IVS fisheye cameras (4000x3000 resolution) that always worked pretty well (video quality in iOS has always been lower compared to the desktop app) but now recently the video quality in the iOS app is very very very bad. It's so bad that you can't use it for anything at all. The previews are fine still.
I posted about this here ( https://support.networkoptix.com/hc/en-us/community/posts/22642388781079-Suddenly-constantly-gettinga-very-low-quality-video-in-iOS-app?page=1#community_comment_22755999534231 ) before and was told the app was rolled back to fix the issue.
Now the issue is back :(

Ruslan Zinatullin, Norman-Nx-Support,
I have also received a report of something similar happening.
Specifically for a high-resolution fish-eye camera, and specifically in the iOS application.
Despite the stream information in the app showing a resolution of around 1080p (H263p), the stream looks like it's much lower resolution, as if the low-resolution stream is being shown instead. Works fine on the desktop client, though.
You guys have any ideas? -
The system is not cloud connected and it's not even accessible from the outside. Only through a VPN. So I'm afraid I can't do that.
I can confirm that the problem is still there. It's exactly the same issue we had a while ago when you guys decided to rollback the iOS app version. That fixed it for a while but now it's totally unusable again.
Video quality is so bad that you can't even recognise a person in front of the camera.

Hi Andy Knuts,
I'm awaiting a build, that contains a change for something else, however, I assume it should also resolve the issue you encounter. I reckon, it should be available today, or early next week.

If you can notify me when a new build is available I can try asap...
Also, when it was working the video quality was much worse compared to the desktop client. I cannot set the resolution higher than 1080p but I have 4k fisheye camera's. When it's receiving only 1080P and I tilt/zoom with the fisheye camera the image quality is really bad compared to the desktop client. That's one of the reasons I'm forced to check in the desktop client regularly...
But that's a different issues. Right now the mobile video quality is just unusable. -
Hi Andy Knuts and Norman-Nx-Support,
This is not a solution but may be helpful in understanding and fixing the issue.
If it's the same issue I am having, you can see that it's the dewarping function that is "triggering" the low quality decoding on the App.
If you disable dewarp for that camera you will immediately be able to see the high quality image without all the "square pixelization" that are caused on the App, but will have no dewarping capability, of course.
Also noted that when you have the issue, the higher the resolution the more obvious it is.
