D435 C# Record and Playback depth and color streams

[MCC001]

Is there any sample available demonstrating recording and playback code using C# ? In the sdk I see there is a Playback and RecordingDevice classes available.. but couldnt find any example using them.

cheers

The link below has a long discussion of recording with C#.

​Within that discussion, a RealSense community member posts the script of their solution here:

I used the above links to further my work and can successfully record images in *.bag file.

however playback using c# still doesnt seem to work.

Below is my code. For some reasons my playback.Status value is always "Stopped". Any suggestions would be greatly appreciated. Thank you.

var ctx = new Context();

        var dev = ctx.AddDevice(@"C:\temp\20190522_133223.bag");

        cfg = new Config();

        pipeline = new Pipeline(ctx);   

        var token = tokenSource.Token;

        using (pipeline.Start())

        using (var playback = PlaybackDevice.FromDevice(dev))

        {

          Debug.WriteLine(playback.FileName);

          playback.Realtime = false;

          playback.Resume();

          var t = Task.Run(async () =>

          {

            var start = DateTime.Now;

            while (playback.Status == PlaybackStatus.Playing)

            {

              if (pipeline.PollForFrames(out FrameSet frames))

                using (frames)

                {

                  var releaser = new FramesReleaser();

Ok i found out what was happening here.

The following command adds another device in the list of your devices.

 var ctx = new Context(); 

var dev = ctx.AddDevice(@"C:\temp\My_test100.bag");

Which means if you still have your physical sensor connected then by default when you do:

var  pipeline = new Pipeline(ctx);

 var pp = pipeline.Start();

This will pick up your physical sensor as the default and attempt to start that pipeline. Which is why I kept getting playback.Status as Stopped.

When I disconnected the sensor from my computer then this code rightly sets up the saved file as a device which you can then start and access frames from.

I can post the whole code if someone wants !

Apologies Eliza - I had been away for a while.

But thanks on this particular issue i dont require any support. There is another issue which I'll post soon regarding Playback.

Thanks
