Can't use sub streams?

[cmx]

I have 6 identical cameras out of the 6 only one of them will let me use the sub stream! All 6 have sub stream turned on all use the same ports, settings, firmware, codec.

But BI using the latest version will not find the substreams on the other 5, i even tired to clone the working cameras settings and then i would just not get video.

The correct video path is

/cam/realmonitor?channel=1&subtype=0&unicast=true&proto=Onvif


if i use that on one of the other 5 i get no video.

FWIW, the URL you posted is for main stream (subtype=0).

When you say ".... All 6 have sub stream turned on...." does that mean you've logged into each camera's webGUI and enabled/configured the sub stream?

EDIT: Are you using "Find/Inspect" to populate the BI video configuration boxes?

Yes find and inspect leaves it blank, Yes all had the sub stream on by default but i did log in and check.

even if i put /cam/realmonitor?channel=1&subtype=0&unicast=true&proto=Onvif

The other 5 will not show any video unless it's left blank.

All 5 are the same.

Goto whatever page/link the camera provides for Users / Accounts.
Select the tab that says Onvif.
Be certain whatever user you're putting in Blue Iris username has a matching Onvif user defined.

It is i use admin for them all. Even though you shouldn't.

This has little to do with your issue but thought I'd mention these recommended initial camera settings for use with BI:

• Encoding strategy: General (or Smart Codec: Off)
• Encode mode: H264
• Bitrate type: CBR
• Bit rate: 8192
• Frame rate: 15 FPS
• Frame interval (iFrame): 15

A while back I had something (forgot what) that wasn't working on one camera, even though all its settings were identical to another same model camera that worked right. I eventually solved it by deleting the non-working camera and reinstalled it, copying the one that worked right.

Yes, I forgot about that....had a similar occurence years ago...
Kind of like how we sometimes forget about power cycling a glitchy device...it's too non-technical and uncomplicated to work, our subconscious thinks.

Just gonna say "me too" when it comes to finally giving up, deleting the camera entirely from Blue Iris, and adding it back from scratch.
