video_recorder not recording the Image stream
I am trying the record a Image stream directly since I do not want to deal with bags. Hence I am using video_recorder but the output mp4 file (output.avi) gives the following error when I try to play the file:
Could not demultiplex stream
I think the error is related with timestamps because the topic I try to record had no prior camera_info topic so I created one myself. Also, if I try to record some other Image topic with an existing camera_info topic on the terminal I can see the following info:
Recording frame 1
Recording frame 2
Recording frame 3
...
and the output .avi file is playable without any errors. But if I try to record my problematic Image topic, those messages don't print on the terminal.
