stream recoder UI and data size limit

[km0703]

I want to hide start and stop button during recode. And I want to take data about 6 minutes but I can only get data of 1-2 minutes.　I do not care about high Hz. What should I do that 2 problems.

Thanks for the help, Minato

Hi, did you find any solution?

Hi, no I did not.

Hi Minato

You can try the patch below for removing the buttons and automatic recording of a fixed number of frames at the start of the app. You can conviniently start and close the app via the Device Portal. It's hacky but does the job.

I did not test for longer recordins though, so I can't help you with your second issue.

Hi friederwC I appreciate your help. We try this code and finally we can delete buttons! Please let me express my sincere gratitude once again.

Has anyone had any luck trying to do long recordings? I'm unable to record anything longer than 1-2 minutes!
