Hello.
I'm trying to save image topic from Full-HD image camera.
I ran my camera package on my pc. The publisher have 5 size of queue.
I have used `ImageTransport` for publisher.
the resolution of a image is 1920x1080. It is approximately 6 MB. And, It have 30 fps.
The throughput of result .bag file is not constant. The variation is 17~30.
I tried to use some option for rosbag record like --buffsize, --chunksize. But there was no change for it.
When I do that, the memory of RAM has continued to increase steadily.
I want to get images without throughput decrease.
Is there any good solution or advise for me?
