VideoStreamer

The video streamer service can stream a video source in MJPEG format.  In order to stream the video, it needs to be attached to a video source.  By default it will stream to port 9090.  Most "real" browsers have the ability to display the video feed.

If you have a webcam, you can start an OpenCV service which will be the video source.  Start the video streamer and attach it to the OpenCV service.  Start a browser and go to http://localhost:9090/output , you should be able to see the video from the camera.

#file : VideoStreamer.py edit raw

from org.myrobotlab.service import Runtime
from org.myrobotlab.service import OpenCV
from org.myrobotlab.service import VideoStreamer
from time import sleep
from org.myrobotlab.net import BareBonesBrowserLaunch

# create a video source (opencv) & a video streamer
opencv = runtime.start("opencv","OpenCV")
streamer = runtime.start("streamer","VideoStreamer")

# attache them
streamer.attach(opencv)

# add a pyramid down filter and gray to minimize the data
opencv.addFilter("pyramidDown", "PyramidDown");
opencv.addFilter("gray", "Gray");

# start the camera
opencv.capture();
#added sleep in order to give opencv the time to "warm up" the cam
sleep(3)


# go to http://localhost:9090/output
BareBonesBrowserLaunch.openURL("http://localhost:9090")

Example for develop:

#file : VideoStreamer.py edit raw

from org.myrobotlab.service import Runtime
from org.myrobotlab.service import OpenCV
from org.myrobotlab.service import VideoStreamer
from time import sleep
from org.myrobotlab.net import BareBonesBrowserLaunch

# create a video source (opencv) & a video streamer
opencv = runtime.start("opencv","OpenCV")
streamer = runtime.start("streamer","VideoStreamer")

# attache them
streamer.attach(opencv)

# add a pyramid down filter and gray to minimize the data
opencv.addFilter("pyramidDown", "PyramidDown");
opencv.addFilter("gray", "Gray");

# start the camera
opencv.capture();
#added sleep in order to give opencv the time to "warm up" the cam
sleep(3)


# go to http://localhost:9090/output
