Start bagfile in enable_device_from_file from a certain position

Hi, I am using enable_device_from_file in my program and I would like to skip some seconds of the bag file, such that it starts a t=5s for example and not at t=0s. Is this possible?

Hi @snopytas It is possible to navigate to a particular frame number of a bag, as described in #3121

If your bag was recorded at a certain FPS speed then conceivably you could work out a rough frame-number starting point from that. For example, if recording 30 frames per second, t = 5 seconds might equate to a rough frame number position of 30 x 5 = 150 (the 150th frame). So if your aim was to jump to a particular position and then begin normal playback from that point onwards, you could maybe set playback to paused first, skip to the desired frame and then unpause playback.

Hi @snopytas Do you require further assistance with this case, please? Thanks!
