It has been over a year since we made the examples and it seems not all streams mentioned work anymore or have different URL's. It turns out the url for this stream has changed to rtsp://streaming5.webcam.nl:1935/live/N302.stream. So just use that one in the example and it should work.

Thank you for your help. But recently when I submit topology, I get following error:
content in supervisor.log:

and error information in worker-6702.log:

[corneversloot]

It looks like you are not able to submit the topology to the cluster since the connection is being refused. Are you sure that you can connect to the Storm cluster using port 6700 (no firewall in the way or other networking issues?).

Thank you for your reply. The problem go away when I refresh the webpage again and again till the video appear.

I am having two errors while I run E2(FaceDetection example)-

1. java.io.FileNotFoundException: Unable to locate /C:/Users/ayush.a/Downloads/opencv/build/java/x64/opencv_java2411.dll

and second one is -
org.apache.storm.zookeeper.server.ServerCnxn$EndOfStreamException: Unable to read additional data from client sessionid 0x154f1f0efa7000e, likely client has closed socket

I have run E1, and it was working fine. Will be grateful for your help.

[corneversloot]

I think the second error is a result from the first one.

The first one has to do with loading the OpenCV library which is needed in example 2 (it was not needed in example 1 which is why that executed correctly). Did you specify the correct library for your operating system as described on the wiki?
If you checked out the master branch you have to use the 2.4.8 version of the opencv library for your OS and not the 2.4.11 one as the example is trying to load now.

[contrast007]

Thank you. 1st error is resolved. I had to use win64_opencv248.dll(in resources folder) whereas I was using opencv2411.dll.
But I am still stuck with 2nd error. The client is connected before, but terminates early.

here is the log-

It does not really throw an error so im not sure if something really goes wrong. Example 2 does not really show anything, it just writes the results (detected faces) to the specified output directory. There are only a few images to process so this goes very fast. Did you check the output directory (default = /output/facedetections/) to see if it contains results?

[contrast007]

That is the problem, It shows no errors but there is no output to the directory.

input files - files.add( "C:/Users/ayush.a/Downloads/StormCV-master/StormCV-master/stormcv-examples/resources/data/faces5.jpg" );
files.add( "C:/Users/ayush.a/Downloads/StormCV-master/StormCV-master/stormcv-examples/resources/data/faces8.jpg" );

output directory -
builder.setBolt("drawer", new SingleInputBolt(new DrawFeaturesOp().destination("C:/Users/ayush.a/Downloads/StormCV-master/StormCV-master/stormcv-examples/output/facedetections/")), 1)
.shuffleGrouping("face_extraction");

Have you solved this problem? @contrast007
