kinect 2 not working with ROS

edit

Hi, I have a problem to use kinect2 in my ROS and look for lots of ways to configure that but still cannot. Firstly, I follow the instructions from:

https://github.com/OpenKinect/libfree...

This link is the kinect driver in linux. It seems that everything works fine except

sudo dpkg -i debs/{libva,i965}*deb; sudo apt-get install -f

it tells me that it doesn't contain libva and i965 directory, and fails.

I used another way to install them:

sudo apt-get install libva-dev libjpeg-dev

I skipped this step, and followed the instruction to the end:

./Protonect

And this gives me four images which includes depth image and RGB image. However, I noticed that, when I executed this command, the output in the screen shows:

jimmy@eaibot:~/libfreenect2/bin$ ./Protonect Version: 0.2.0

Environment variables: LOGFILE=<protonect.log>

Usage: ./Protonect [-gpu=<id>] [gl | cl | clkde | cuda | cudakde | cpu] [<device serial="">]

    [-frames <number of frames to process>]

To pause and unpause: pkill -USR1 Protonect

From here, it shows there's some problem with the libva, however, I don't understand what the reminders mean. I used to be happy with the image and continue to work on the ROS. and the ROS results turn to be fairly disappointing!

I found a kinect ROS driver which is called iai-kinect2:

https://github.com/code-iai/iai_kinect2

And it fails when I run

roslaunch kinect2_bridge kinect2_bridge.launch

This is the main problem.(I want to show you the overall message from the screen, but sorry, I don't know how.) And it shows me no message and always shows some problems:
