Currently, I'm running Indigo on Ubuntu 14.04 on my Nvidia Jetson TK1.
I'm trying to stream rgb from my Asus Xtion Pro Live rgb to a web browser using openni2 and mjpeg_server. I used openni v1 previously, and how i did it was simply by running roslaunch openni_launch openni.launch, and rosrun mjpeg_server mjpeg_server _port:=8181. I put the url (in my case, http://192.168.254.100:8080/stream?topic=camera/rgb/image_color/) in an img tag on a webserver, and I could see the rgb stream perfectly.
But with openni2, I tried to do the same, running roslaunch openni2_launch openni2.launch and rosrun mjpeg_server mjpeg_server, but I can't view any rgb stream on my web browser. When I connect though, I can see that mjpeg_server recognises it and says Client connected. 1 subscribers for /camera/rgb/image_color.
$ roslaunch openni2_launch openni2.launch

Can anyone tell me if I did anything wrong?
