camera1394 from launch

When I attempt to roslaunch a camera1394 node with a camera.yaml file, I get the following error:

yaml-cpp: error at line 1, column 1: key not found: image_width This indicates that the camera is uncalibrated, which it is. Unfortunately this means that I can't get color images working, despite having determined bayer patterns and the like. At the moment, I don't want to have to calibrate the camera, but would like the color images out of the camera1394 node. Is there a way to run the camera1394 node without the calibration portion?

Here is my launch file:


  <group ns="ffmv">
    <node pkg="camera1394" type="camera1394_node" name="ffmv">
      <param name="guid" value="00b09d0100a80b41" />
      <param name="video_mode" value="640x480_mono8" />
      <param name="iso_speed" value="400" />
      <param name="frame_rate" value="30" />
      <param name="bayer_pattern" value="rggb" />
      <param name="bayer_method" value="" />
      <param name="camera_info_url" value="file:///home/bradpowers/ros/ros_tutorials/cv_bench/params/ffmv.yaml" />

    <node pkg="image_view" type="image_view" name="image_view" >
      <remap from="image" to="camera/image_raw"/>

    <!-- Debugging Tools -->
    <node pkg="rxtools" type="rxconsole" name="rxconsole" />
    <node pkg="dynamic_reconfigure" type="reconfigure_gui"
          name="reconfigure_gui" />



And my corresponding ffmv.yaml file:

{auto_brightness: 2, auto_exposure: 2, auto_focus: 5, auto_gain: 2, auto_gamma: 0,
  auto_hue: 5, auto_iris: 5, auto_saturation: 5, auto_sharpness: 5, auto_shutter: 2,

How do you get your ffmv.yaml file? Thanks

Ok, problem solved. Instead of using the camera1394 node as is, I'm using some of the nodelets that comprise it, namely the camera_nodelet_manager, camera1394_nodelet, and the image_proc_debayer nodelet. Here's my .roslaunch file:


  <!-- nodelet manager process -->
  <node pkg="nodelet" type="nodelet" name="camera_nodelet_manager"
        args="manager" />

  <!-- camera driver nodelet -->
  <node pkg="nodelet" type="nodelet" name="camera1394_nodelet"
        args="load camera1394/driver camera_nodelet_manager">
        <rosparam file="$(find cv_bench)/params/ffmv.yaml" />

  <!-- Bayer color decoding -->
  <node pkg="nodelet" type="nodelet" name="image_proc_debayer"
        args="load image_proc/debayer camera_nodelet_manager">
    <param name="bayer_pattern" value="rggb" />
    <param name="bayer_method" value="" />
    <remap from="image_color" to="camera/image_color" />
    <remap from="image_mono" to="camera/image_mono" />
    <remap from="image_raw" to="camera/image_raw" />

  <!-- Image View Node -->
  <node pkg="image_view" type="image_view" name="image_view" >
    <remap from="image" to="camera/image_color"/>

If someone could mark this as the correct answer, it'd be much appreciated, as I can't.
