Frame rate on mobile

villasueno35 · Nov 14, 2018

Here is an odd thing I just noticed. See the screenshots. On the mobile app you can see it is reporting a frame rate of near 25, but if you look at camera set up it is set to 5 on mobile and 8 on desktop, and in bi it is called to 10.

Why does the mobile report wrongly?

Any ideas?
Thanks
Darren

i found the bug in BI! So, you set frame rate to 10fps, all ok. But, if you had an older video of a higher frame rate (25fps) and watch that video it resets the video fps on that camera to that video frame rate (25 fps). So, I set my fps to 10, i double checked it was saved, said 10fps, i then watched a video it recorded last night at 25fps (as it set itself wrong) and then when i when back to camera>video the fps was back to 25... reset to 10, watched another video, set back to 25.

so there is a bug. will try to report to BI dev, not sure if they read on here, i have tried reporting bugs in the mobile app but never bother to reply.

seems on further investigation this is not watching a video, if i set the camera in bi to 10 fps, it is ok for about 15 seconds, then goes back to 25fps regardless, always, 20 times over it did this. so i went to camera settings, i had that set to h265 no smart codex, vbr, 8fps (which had all previously worked) and in bi using no hardware acceleration at all as that does not work with h265, but, seems the h265 is consfusing bi as i changed that to h264h and now bi camera?video retains the 10fps - shame as now my videos are 3-4x the size on disk with all other variables the same. so seems there is a bug in the h265 from the camera (dahua) to bi. I have reported to BI

Does the camera have an memory card in it. If so how does the file sizes compare for the same period between the memory card and BI?

No it doesnt

fps can never be adjusted in blue iris, only in the camera. The setting in blue iris does nothing. The fps that blue iris is showing will not affect the file size. The ONLY thing that will affect file size is the bitrate coming from the camera.

even more strange then as the camera was 100% set to 8fps main stream and 5fps sub stream, I was running lots of tests the other night to find the best trade off in quality/file size etc and set on 8fps, vbr, bitrate capped to 1280, etc, but was sending 25fps this morning despite camera showing 8 and bit stream capped to 1280 on vbr, and this was sall at night in a black room with no movement.

again you are confused. File size is dependent on one thing only, the BIT RATE. If the camera is sending 25, there is nothing blue iris can do, its a camera issue.

but surely if i capped bit rate at 1280 (not sure what that equates to in fps) how could it send bi 25fps, its just odd, as i had it all setup, it ran one night and 1 hr of video was 44mb, last night (no settings changed on camera or BI) 1hr of footage was 130mb, same environment, same camera (only got one running for now getting things setup), so with no setting changes, same environment, same pc, same camera such a difference in file size and the only thing I see that was different was the fps in bi, ho hum, thanks anyway

I have a camera that has a file size difference every hour of the day and from day to day. Motion changes the file size, light changes the file size.

The only way I have the same file size is to point the camera at a colored wall,with a bright fixed artificial light.

The math for the compression is very complicated.

Changing the bit rate limit does not affect your FPS at all. The camera just reduces the quality of all the frames until they fit into your bit rate limit.

thanks, i have learnt a bit more on bit rate, and have bit rate capped, but, my camera is set to 7fps (changed last night), and yet bi still reports 25fps, so i can only assume now there is some fault on the camera as i have been told a few times now that bi max frame rate does nothing and the camera controls that, which i get, but just then dont get why my camera is set to 7fps and bi reports 25, stumped, anyone else seen this on a dahua camera and found a fix? firmware upgrade or something?

mine is the dahua ipc-hdbw4631r-zs

thanks

Reboot everything. The bi PC and the cameras.
Also make sure that all cameras have unique static IP addresses.

you have it set to vbr, it can go lower than 1280

Why don't you feed the rtsp to another destination like VLC..you will see it's also at 25 fps....that is a hacked China region camera.
