creating color rosbag

[razramon]

Hi T. Stoffregen, thanks for your hard work.
My question is: the bags created are videos in grayscale, is that correct? or has something gone wrong at my end, because I thought that ESIM suppose to output events, like their example: https://github.com/uzh-rpg/rpg_esim/wiki/Simulating-events-from-a-video
Second, is there a way to make color bags? We are inputting RGB images, and I was hoping that we could output an RGB bag, and then maybe use bag2vid on that.
Thanks so much,
RazRamon
