Snapshot quality

[satoshi]

It was added to an update after substreams where introduced:

From the help file.
5.3.3 - October 1, 2020
When using dual-streaming, JPEG images will be created from the main-stream instead of
the sub-stream where possible. Rather than fully spooling up main-stream decoding, the
software uses the direct-to-disc pre-trigger frames buffer to synthesize these images. This
means you should specify at least enough pre-trigger time on the Record tab to span the
key-frame interval for your main-stream.

And yes, the issue of the clone camera without the substreams then makes it not a clone and motion detection will be made from the mainstream then and then you are pulling two video streams and actually using more CPU.

i am trying to retrieve the snapshot using the REST API call:

/image/{cam-short-name}

Still getting the substream version of the snapshot. Any ideas if it is even possible to obtain the highres version?

I am not using REST API, but if I set the camera to take a high res snapshot it does. So I would think it would be possible to retrieve it with REST API.

can you share which one are you referring to?

the one in trigger...add to alerts list: "Hi-res JPEG files" or in rhe Record tab check JPEGs?

 

[wittaj]

I am doing it on the record tab and check JPEGs

just tried that, same thing, substream version of the snapshot when using:

http://blueirisserver/image/

{camera_name}

To get a snapshot from the mainstream, use

http://blueirisserver/image/

{camera_name}&decode=1

great!! this is what i was looking for, thanks a lot. (while still waiting for Blueiris for support email....useless)

I'm using the Snapshot function from the Events schedule... for a few cameras (page 89-91 current of

https://blueirissoftware.com/BlueIris.PDF;

the Schedule and Events heading), and the snapshots are from the sub stream .

I just tried this and cannot replicate your observation.

Getting Hi-res snapshots may be dependent on having one of these options enabled:
1. Trigger tab > Add to alerts list > Hi-res JPEG files
2. Trigger tab >AI > Burn label markup on to alert images
