B4J Code Snippet Synology Surveillance API

A simple example of working with Synology Surveillance API
added possibility work with https:
1 take a sid for current session
2 check all available cameras
3 make shots from each camera to file
TODO
One of mine camera work on rtsp with H.264 video
snapshot file started from

���� Lavc56.60.100

Any suggestion of easy way to transfer it to jpg or png

Is it actually producing proper JPEGs? I would think that

Dim tfile As Long= DateTime.Now
File.WriteString(File.DirApp, tfile&".jpg", j.GetString)

would corrupt the JPEG, since j.GetString returns a string, not binary data, and File.WriteString writes a string. That actually works?

 

[DonManfred]

That actually works?

I don´t think so

 

[Molchyn]

That actually works?

I don´t think so

it's return stream snapshots
one camera JFIF format
and next H264
samples attached in file

Looks like the *21.jpg file contains the H264 capture and the *03.jpg file contains the JFIF format. Neither open properly for me. Do they for you?

 

[Molchyn]

Neither open properly for me

Yes for me too.
But then I change from string to stream it's work like charm
