Blue Iris Live video shows jaggies every ~20 seconds

I have a number of Blue Iris systems out in the wild using the 5442 camera from Andy. Viewing the Live view directly on the camera admin UI shows smooth video, however, when I view the live video using my Blue Iris iOS app, I get jaggies every 20 seconds or so. I've checked and this occurs on most if not all of my systems. It seems I'm missing some common setting.

The camera in question is running full rez, 20 fps, 40 iframe int. No hardware acceleration on BI, running an i5-3470. CPU usage around 30%.

Sample of issue below. You'll see at 1:00:30 it just jumps 4 or 5 seconds and the jaggies show up.

Match the iframe rate and frame rate. That is the recommended setting by Blue Iris. It needs to be a ratio of one. Motion detection starts on the first available iframe.

This vid was recorded on your phone?
Have you performed ALL the optimizations listed in the wiki on BI?
You may have the bit rate set too low in the BI phone app it's self, increase it.
To be honest, I see those same issues on my android app on my phone, and have never been able to solve it. Ken doesn't seem interested in fixing it.
 
The video was recorded using the video capture option in the BI iOS app while viewing a clip of this camera. Will go back and check the wiki. I have the FPS set at 21 in the BI app.

EDIT - I have 7 other cameras on this system (older bullet style Dahua) that do not have the issue, so it's not system wide.

Does this problem occur when viewing on the BI console ?

I'm not sure if this happens on the console because I'm headless accessing via RDP. I can connect a monitor and see if it happens.
 
headless a major clue...
Are you using a dummy HDMI plug ?

I am not using a dummy plug. Could I just hook up a monitor to the machine instead?

Just hooked a monitor up and I do NOT see the issue when viewing this camera in the console. I still see the issue in the iOS app.
 
a monitor would be OK. The I2 in the HA column indicates that you are using some hardware acceleration processing.

Also note that on the driveway2 camera you have a lot of No signal errors
You are not using WIFI ? If wired check your connections.
 
I've gone back and checked some of my other systems and they're all doing this on one camera or another... no real rhyme or reason to the model or make. Frustrating.
 
Is it not the default streaming profiles with their low bit rate settings? I always end up upping them in my streaming profile for UI3 because of this. If I don't, when using UI3, I get those terrible jaggies. There is a similar setting in the BI console for the apps that will determine the bit rate that is sent to them.

That's something I haven't investigated. Can you provide more info on what to check/change?
 
Settings -> Web server -> Advanced -> Configure (for streaming Profile 0). Inside of that you can see the default were it limits the bit rate and video quality. Either uncheck it, or change either (both) to a larger number.

That seems to have done the trick! I unchecked the limit option and set the quality to 100 as a test:

I don't see the jaggies or time jump every ~20 seconds now. Thanks for the tip!

Just keep in mind that when you are on regular cell data (LTE) then its possible that you may not get fluid video depending on your cell connection strength and bandwidth since you aren't compressing the video any longer. Its a trade off of course.

Got it! I'll fiddle with it to get it down to where it's optimized but not showing the issue. Thanks again
