[Elphel-support] question about elphel 353 camera

[重点实验室]

Andrey, 


Acturally I have tried cvCaptureFromFile("http://192.168.0.9:8081/img"), or "bimg". Sorry for forgetting typing "/img". 
http://192.168.0.9:8081/bimg works in an internet browser,  but how does it works in an opencv program?  


Wei

Wei,

I would still recommend to use 8081 port for individual images directly, not through the streamer. http://192.168.0.9:8081 will not give you an image - it just opens a mini-help page that explains how to get image. The simple way (if you do not need synchronization) will be http://192.168.0.9:8081/bimg

Hello Andrey,


I have tried to get a image by cvCaptureFromFile("http://192.168.0.9:8081"), but not succeed. In firefox, it works. 
With live555 I can download a sequence of image with its example program openRTSP. I use rtsp://192.168.0.9:554 in live555, the data are stored in a buffer. I want to decode the data from the buffer. I find the buffer in live555, but did not find the way to deal with it.
I just want to get an image from the camera with an opencv function or maybe some other c/c++ function.

Hello Wei,

Did you get static jpeg or jp4 images from the camera port 8081 as I suggested? live555 software is for videostreaming, not for the images, and last time you asked how to get images.

Hi Andrey,


Now I can get the image data from the camera with live555 software. I use its dummysink, the data is not The data is put in a buffer, it looks like noise. I think it is encoded image data. Is it a jp4 encoded file or a jpeg encode file?
