Export short clip via api?

[jonrub11]

Hi,

Is it possible to export a short videoclip of an event via api? I am thinking of a video like the one I can get when using the email notification that is 10 seconds long.

Thanks in advance!

Yes. See the Blue Iris help file > Administration > JSON interface. Scroll to the "export" command, currently on about page 222.

It isn't something you can simply do with one request. First you need to log in, then get a clip list to obtain a clip ID (if you don't already have one). Then begin the export. Then poll for status until the export completes. Only then can you download the exported file.

Thank you @bp2008!
Do you have any idea of "startms" for the export? How do I know what to set here?

 

[bp2008]

That would be for if you wanted to skip some time at the beginning of the clip. For example if you only cared about the video after the first 30 seconds, you would put a value of 30000 there. To start the export at the beginning of the clip, just set 0.

Thank you very much for your help. I am using continuous recording and when I try to export the file below I get a video that is 15 minutes long.
'{"cmd":"export","session":"48534f5555c571490414490f7bb107e4","path":"@36733140.bvr","startms":"0","msec":"10000"}'

I just want 10 seconds around the alert so there is something I am doing wrong.

 

[jonrub11]

Solved it by removing "" around the startms-value and msec-value. Like this: '{"cmd":"export","session":"48534f5555c571490414490f7bb107e4","path":"@36733140.bvr","startms":0,"msec":10000}'

@bp2008 Any idea of how to make the file smaller? I have tried to edit a profile in Convert/Export and set "profile":2 but the file size is still the same.

 

[bp2008]

You did not tell Blue Iris to re-encode the video. There is a separate argument for that.

 

[jonrub11]

Gaah, thank you @bp2008!
Last step is poll for status. Do you any exemple? I have not managed to get it working yet.

UI3 is a giant example of almost everything in Blue Iris's JSON API.

I tried to look at the code but I am not good enough to see how to get status for a single event.
I have tried with this {"cmd":"export","session":"$sessionvariable",path:"pathvariable"} but it doesn't work.

I don't understand this in the manual "Send only a path with a previously obtained path to obtain status on a single item. Send only the export command without a path to receive an array of items in the export queue.".

I think when you begin the export, the response from that will include a path variable which you can use to query for status updates.
