Rainbow Corruption

bp2008 · Jul 11, 2016

Has anyone seen this type of corruption appear before? This is happening at random to my Hikvision cameras -- all 3MP models running at 1920x1080 so far -- for a couple weeks now. Usually I log in and find two of them all corrupted like this.

The corruption pattern is continuously changing, and this triggers motion detection and creates recordings, but the interesting thing is that the recordings (done with direct to disk) are fine and look perfectly normal -- no rainbow corruption. This is only affecting the live view, and it can be (temporarily) fixed by restarting the camera in Blue Iris. I emailed Ken about this yesterday but if anyone else is having the same issue, it would help to know about it so I can rule out any issue with my particular system.

Bp...I've never experienced corruption quite that bad before, however I've had similar results when using hardware acceleration in Blue Iris with my Hiks using H.264+. I have to use the standard H.264 with hardware acceleration in order to keep a clear video stream. Not many folks here have the same level of experience as you do with BI/camera setups, so I doubt I'm telling you something you don't already know. Good luck and please keep us posted.

Ken said he had not seen this before either, but that it might be hardware acceleration causing it. So I disabled it for the two cams doing this the most and they haven't done it again in the past 24 hours. However an hour ago a different cam started doing it.

I hope my CPU isn't starting to glitch out.

I saw that rainbow corruption once back in '73 at the Watkins Glen Summer Jam during the Allman Brothers' set; strong blotter it was.

This hadn't happened for the last two months, but began reoccurring in one camera after updating to 4.4.4.1. Maybe a coincidence. Maybe not. This has still only happened to my Hikvision cams... this time a Swann branded one from Costco years ago. Firmware Version V5.0.0 130412. H264+ isn't even an option.

Isn't H264+ a Hikvision proprietary algorithm and not compatible with anything other than a Hikvision NVR? I'm asking for my own education.

I have had this exact same thing happen a few times myself. Same thing just restart cam and it is good again.

Now that is interesting.

I see that particular corruption when I view a Hikvision h264 RTSP stream on an Apple TV2. Works fine on any other device that I have that does h264.

I might have a plat with the profile settings when I get a moment and see if it is related to that. I'll also see if I can disable hardware decoding and see if it gives a usable image.

Any news on this?

I activated H.264 hardware acceleration today (BI 4.4.5.0 x64) to try and reduce CPU load, and it works perfectly for my two Hikvision camera's, but my Foscams (R2) give the strange patterns as described here. Are the Foscams not producing the right H.264 format perhaps? Can't seem to find any settings for that in the camera web UI.

It just happens at random for me. Hasn't happened again in about a week.

Tinman · Jan 21, 2017

This started again on mine for the last few weeks. Same thing, clips are fine via D2D but the live view and clip image is rainbow effect. I have tried many settings to no avail and I hadn't changed anything prior except for updating BI. Running 4.4.9.10 x64

what hardware is your BI machine, have you tried updating chipset drivers directly from the manufacturer? the fact that its only live view thats like this makes me think the display framebuffer is getting corrupted; perhaps a bug in video card drivers.. iirc its tricky to get Win10 to not auto-update hardware drivers and that could explain the sudden issue.

checking now for updated drivers.....looks like I am current on them and they have not updated for awhile. Bp2008 was also experiencing this and I was curious if he found out what the culprit was.

I'd rather use regular h.264 with hardware acceleration than turn it off and run h.264 plus, hard drive space is cheap.

bp2008 · Jan 21, 2017

This still happens to me, although quite rarely.

It could be a graphics driver problem, but given that there are worse problems (like the memory leak) in newer drivers, I'm not too eager to update.

Only problem I ever had with a BI machine was when I first got the first one I had it would lock up, I took out the discrete video card and it was good to go, it was just a cheap box I got for free anyways because I needed something to run cameras on, knock on wood. I hate intermittent issues like that, they are so damn hard to nail down. But yeah, you could schedule a daily reboot of each camera, staggered of course, if you aren't already doing that.

That is an old driver...Download Intel® Graphics Driver for Windows® 10 and Windows 7*/8.1* [15.33]

Ah, I was thinking Gigabyte. I updated them and will see if that eliminates the issue.

So far no rainbow effect after updating drivers. I also see no sign of memory leak as well. If it comes back I will update thread.
