Another Way to get Session Recorder files?

October 26, 2020 - 5:50am #1

Hi,

I wanted to try the new Session recorder today. Everything regarding the recording itself went fine, but I can't ssem to get the recordings from the HoloLens onto my PC.

I tried using the Device Portal to download single files, but I always get a timeout (but only when trying to get files from the LocalAppData directory). I tried using Advanced REST Client (a tool to make REST calls and test if they work) to do the GET call by hand as described in the Sessions Recorder guide and after some time I got it to request a single camera frame file (the .xpgm ones), but then that tool freezes. And when I try to use the /file endpoint on a directory (like one of the folders in the LocalState/Recordings directory) it gives me a 404.

Over USB the HoloLens doesn't let me access the LocalAppData folder apparently. So now I am a bit stumped. I was hoping, that someone has found a different way to get the files. (Preferably something convenient like just drag n dropping them over USB :D).

Thanks

 

edit: I also thought about trying to make a simple app for Android, which would only contain the Session Recorder. But I worry that the difference in device (Hololens vs Phone) has an impact on the suitability of the data to test my Hololens app.

Ok thanks for the answer. I captured our footage with a smartphone app for now. The tracking on the captured footage doesn't seem to be as stable as with the realtime tracking on the Hololens, but it's usable for now.

Hi,

We have the guide here; https://library.vuforia.com/content/vuforia-library/en/tools/recording-playback.html which goes over how to access information on the Hololens. Based on the information provided you already tried the recommended steps and it failed.

I will check if we have any other options regarding HL, however I do believe we would have mentioned it in the documentation if we had a drag and drop approach.

In regards to your last questions, the device used for capture does not matter, what is important in my view is the below information mentioned in the guide.

It is worth mentioning that it is important to work out the scenario you wish to capture before recording. A clear strategy on what to capture; whether it is user centric, sequential steps, or targets under environmental constraints, will reward you with an ideal recording that can help in the development process and result in a capable AR application.

Thank you.
