usage:

rosbag2video.py [--fps 25] [-o outputfile] [-s (show video)] [-t topic] bagfile1 [bagfile2] ...

converts image sequence(s) in ros bag file(s) to video file(s) with fixed frame rate using avconv
avconv needs to be installed!
if no output file (-o) is given the filename '<topic>.mp4' is used and default output codec is h264
multiple image topics are supportet only when -o option is _not_ used
avconv will guess the format according to given extension
compressed and raw image messages are supportet with mono8 and bgr8/rgb8

-t topic
only the images from topic "topic" are used for the video output

example output:

rosbag2video.py -r 50 -o test.mp4 peng_2015-12-14-13-*.bag
using  50.0  FPS
/cam_peng/color_rect/image_raw/compressed  with datatype: sensor_msgs/CompressedImage
