The (ugly) way that I have done this in the past, is roughly like this:

import subprocess, shlex
command = "rosbag record -O subset /camera/depth/image_raw /camera/rgb/image_raw /joy /mobile_base/sensors/imu_data_raw"
command = shlex.split(command)
rosbag_proc = subprocess.Popen(command)

and this is how you can kill the recording process:

rosbag_proc.send_signal(subprocess.signal.SIGINT)

The (ugly) way that I have done this in the past, is roughly like this:

import subprocess, shlex
shlex, psutil
command = "rosbag record -O subset /camera/depth/image_raw /camera/rgb/image_raw /joy /mobile_base/sensors/imu_data_raw"
command = shlex.split(command)
rosbag_proc = subprocess.Popen(command)

and this is how you can kill the recording process:

for proc in psutil.process_iter():
    if "record" in proc.name() and set(command[2:]).issubset(proc.cmdli    ne()):
        proc.send_signal(subprocess.signal.SIGINT)
