Unable to get this streaming with a Hikvision mjpeg stream

[jimt...@gmail.com]

I've been fishing around trying to get this to work, here is my current setup:

1) I have a Hikvision camera.  I've set its substream to be mjpeg as shown in this image...

2) I tested this stream in VLC, by connecting to the following network stream: http://admin:P455...@10.120.111.244/Streaming/Channels/2/preview.  No issues there, streaming correctly.

3) I modified alprd.conf with the following line: stream = http://admin:P455...@10.120.111.244/Streaming/Channels/2/preview

4) I ran alprd, to no avail...First on MacOS:

./alprd -f --config ./config/
INFO - Running OpenALPR daemon in the foreground.
INFO - Using: ./config/alprd.conf for daemon configuration
Missing config value for company_id
Missing config value for pattern
INFO - Using: /var/lib/openalpr/plateimages/ for storing valid plate images
INFO - country: us -- config file: ./config/openalpr.conf
INFO - pattern:

INFO - Video stream connecting...
VIDEOIO(cvCreateFileCapture_AVFoundation (filename)): raised unknown C++ exception!

And then again on a fresh Ubuntu install:

INFO - Running OpenALPR daemon in the foreground.
INFO - Using: /etc/openalpr/alprd.conf for daemon configuration
INFO - Using: /var/lib/openalpr/plateimages/ for storing valid plate images

INFO - Video stream connecting...
WARN - Stream http://admin:P455...@10.126.141.204/Streaming/Channels/2/preview?openalprfiletype=file.mjpg failed to open.

What am I doing wrong here?  I'm simply trying to get the alprd daemon running against my Hikvision camera stream.  Thanks for any help you can provide!

Hi,

you're not doing anything wrong, it's in the daemon code :  it appends "?openalprfiletype=file.mjpg" when it tries to open an http video stream source that does not already have an .mjpg extension.

Apparently to help OpenCV.

I tried to work around that previously, change the code, recompile... but i ended trying to get OpenCV handle the rtsp stream instead as the MJPG streams are getting rare now.

And it works pretty well, but with a newer version of OpenCV, I don't know which one you use.

I spent a few days  compiling OpenCV 3.2 from source with the modules (ffmpeg, gstreamer, OpenCL etc..) with OpenALPR 2.3 and it works like a charm with x264 rtsp streams now.

Try to stream using RTSP protocol

syntax: rtps://username:password@ipaddres:rtspport(default 554)

Example : rtsp://admin:admin%40...@192.168.1.1:554

Hello, what kind of camera is this? LPR or just IP camera?

Can I use the OpenALPR Daemon without using Cloud Stream? Just python Integration?

Please reply I need your help

Hi There.

I'd like to stream from a Hikvision to OpenALPR as well, using MPEG, but just found your thread. Have you resolved this? With RTSP or MJPEG?

Regards

Markus

Bara-

I am interested in how you were able to get OpenCV to handle the RTSP stream.  Do you still have access to the code or documentation?  I am hoping to be able to implement a similar application on my device and would appreciate any assistance you could provide.  Thanks!
