Hi, is there any function for converting CameraInfo sensor messages to images. I'm aware of CvBridge library but it seems to me like it only works for Image sensor messages. I appreciate your help!

Edit:

Sorry if you misunderstood me. Video was recorded from the camera, but the .bag wasn't recorded using Image msg type. It's structured like this:

some header
     <Preface Index>    // preface frame index
     <Message Data> // first frame record
....
     <Message Data> // last frame record
<Index Data>    // index of all records in the previous chunk
<Connection>    // connection specs
<Chunk Info>    // additional chunk info

So, when I type rosbag info in command line, I get only CameraInfo msg type recognized, but that msgs are probably containing our special format.

So, what I'm then interested in is how to access/view the content of these msgs?
