My tech leader on RHIoT project (ex-camellabs) Henryk had just release the last version of RHIoT project : 0.1.2. Lot of new stuffs are included in this new release, more details available here. I found in list a cool stuff to test. We gonna check if our new commiter @levackt from ZA worked well ;-)
Webcam camel component on Mac OSX with Groovy language
Let’s start to broadcast yourself.
Requisites
- Have a mac
- tested MacBook Pro Retina, 13-inch, Mid 2014
- Groovy Mac port installed
- Groovy Version: 2.4.4 JVM: 1.8.0_45 Vendor: Oracle Corporation OS: Mac OS X
Program
We gonna use Groovy language for this simple example. Groovy provides a concise and expressive syntax that makes it perfect for quickly testing new components like this webcam integration.
The key point of this program are :
- the @Grab annotation to download camel-webcam component :
@Grab(group="io.rhiot",module="camel-webcam",version="0.1.2") - the from command to capture image every second :
from("webcam:cam?consumer.delay=1000")
Copy log4j.properties into the same directory to properly configure logging:
Execution
Let’s run it now. The following output shows the Camel context starting up, initializing the webcam component, and capturing images at regular intervals:

And the result
After 5s of running, you can find all images into webcam directory. The component automatically creates this directory and saves each captured frame as a separate image file. Here are some examples of the captured images:
Conclusion
With this small example, we can see the power of camel and the integration with hardware component managed via Rhiot project. Just imagine a camel including both webcam and websocket components. This would allow you to create a real-time video streaming application with just a few lines of code.
I would like thanks a lot Taariq Levack for this so cool component ;-). I’m sure he will provide some new cool stuff like this one soon.
The RHIoT project continues to expand the Apache Camel ecosystem with IoT-focused components, making it easier than ever to integrate hardware devices into your integration flows. This webcam component is a perfect example of how the project is bridging the gap between traditional integration patterns and IoT applications.
