Issue Description

I was trying to call the 'seek' function in rs2::playback to control the playback of .bag files.

However, PyBind issue a critical error as it was unable to translate the float parameter into the Chrono object. It suggested me to re-check the compilation of the PyBind headers.

Is this implementation incomplete? Alternative, is there an easier way to seek a .bag file and also be notified at the end of the playback?

Thanks.

Hi, thanks for the support.

Is there a Python example where I can use a playback device context to read all video frames without frame drop?

Hi @jimmy82
At the moment, no, but we will try to add such an example (@lramati / @AnnaRomanov could you please assist?)

I'm closing the seek issue. We are looking into adding the python code snippet you requested. You can open a separate issue on this for follow-up if you'd like.

Hi, Thanks. It will be good if Python documentation can be beef up.

Hi, I haven't found any functioning example of playback.seek in python

I can get playback. [current_status,file_name,get_duration,get_position,pause, resume, set_real_time] all working

but seek still throws back error

TypeError: seek(): incompatible function arguments. The following argument types are supported:
    1. (self: pyrealsense2.pyrealsense2.playback, Sets the playback to a specified time point of the played data.time: datetime.timedelta) -> None

Invoked with: <pyrealsense2.device: Intel RealSense D435 (S/N: 817512071792)>, 0

in which the type of my playback is <class 'pyrealsense2.pyrealsense2.playback'>
it should be correct, I would like to ask if you can also answer this

thank you

Can you please open a new issue for your problem and indicate when version of the SDK you are using and what the line you tried to run is?
